Glossary of Website Terminology

Common website terms and what each one means.

The terminology used within the web industry can be a little daunting because many website terms are not used in our everyday language. This is why Thinking IT’s website designers speak in layman terms, so you can understand exactly what is going on with your website.

To have a better understanding of how the web works, you will need to become familiar with terms that you may not fully understand the meaning of, so to help you Nigel Brookson complied a list of commonly used website terms with their definition.

Commonly used Website Terms and their Definitions.

ACCESSIBILITY: Relates to web design/coding standards and refers to how easy it is for everyone to use your website, including people who are visually impaired or in any way physically handicapped, or limited by older or less common computers and software. These days with the smaller screen sized tablets and smart-phones, accessibility for use on all devises is important; especially with the growing number of people using smaller screen devices to go online.

ADDRESS BAR: The white bar towards the top of your computer screen. It will normally have something typed in it that starts with "http://" This is where you type in the address of a website that you want to visit.

ANCHOR TEXT: The text a link (hyperlink) uses to refer to your web page. These make a difference in your search engine results.

ASCII: American Standard Code for Information Interchange. A code that represents English characters as numbers, ranging from 0 to 127. Commonly used by computers and browsers, ASCII codes make it possible to transfer data from one computer to another computer (like a server). In terms of transferring data from a computer to a server (called "uploading"), you would need to use either ASCII or Binary, depending on the type of file being transferred.

ASP: A coding language that is compatible with Windows servers. Normally used for increased functionality on a website or to work with a database. It works in conjunction with html and html variants.

ATTRIBUTE: An attribute supplies additional information within an element. Attributes come in name/value pairs and are always inside the start tag.
Looking at this simple example of an a tag (), hyperlink the href is the attribute name with its value. The syntax or rule for attributes is: attribute name="value" and they appear in the start tag (< >).

BANDWIDTH: It may help if you read "traffic" first, but very simply, bandwidth relates to how much a resource is used. An analogy would be a freeway. The wider the freeway, the more traffic (users) it can handle. The narrower it is, the less people can use it at once (without problems).
When a website gets a lot of visitors, it will use a lot of bandwidth.

BCC: Means "Blind Carbon Copy". An email feature. If you send someone a BCC email, their email address will not show in the "to" field.

BELOW THE FOLD: This term is a carry-over from newspaper publishing days. In newspaper terms, “below the fold” means content was on the bottom half of the page (below the physical fold in the paper). In web design terms, “below the fold” refers to the content that is generally going to be below the point first viewable to the average website visitor in their browser (in other words, viewers would have to scroll down to see the content).

BETA: A term used for software that is in a "live" testing phase. People can use it but can expect some hiccups.

BINARY: A numbering system that consists of only two numbers, 0 and 1. Everything that you type or input into a computer is converted into binary – a unique combination of the zeros and ones. Screens and printers then convert this binary code back into what you inputted. When uploading (transferring) information (files) from a computer to a server, certain files need to be transferred as binary in order to be correctly interpreted and rendered. The alternative to binary for uploading is ASCII.

BLOG: An online journal or diary and a very popular current method of sharing your thoughts with the world. It is also very popular as a marketing tool. This article is found within Thinking IT’s blog.

BOUNCE: When you send an email to someone and it comes straight back to you with an error message, it is said to have bounced. It’s like the internet version of "return to sender" except it is a computer or piece of software automatically sending it back to you, not a person. Emails can bounce for many reasons. The most common are: you made a spelling or typing error in the address, making the address invalid; the person you are sending to no longer has that email address; the person you are sending to has let their mailbox become too full to accept new emails; a piece of software on the receiving end thinks that your email is spam or that it includes a virus and sends it back to you.

BOUNCE RATE: A website’s bounce rate is the percentage of people who leave the site from the same page they entered the site, without clicking through to any other pages. This can be a good indicator of how good a website’s navigation is, as well as an indicator of the quality of the site’s content (a very high bounce rate doesn’t bode well for either of those things).

BROADBAND: Relates to a type of internet connection. When someone says they have a broadband connection it means they are connecting using a service that provides greater speed. ADSL is one example of a broadband connection. It also often means greater reliability because you will not experience as many time-outs and also because more people can use a broadband connection at the same time without it causing "traffic congestion" (which slows everything up – just as it does when you are driving on a busy road).

BROWSER: When you visit a website, you are seeing it on a browser. Websites look very different in reality to what you see when you visit it. Everything is in fact encoded. A browser is the piece of software that decodes everything so that what you see is an attractive page rather than a lot of coding. Most people use the Microsoft Internet Explorer browser, which comes with all Windows software. If you look at the top right of your screen right now, just under the "X" you will see a little picture. This picture tells you what browser you are using. If the picture is a wavy square with smaller squares in red, green, blue and yellow, you are using IE (Internet Explorer). If it is something different, then you probably know all this already.

BROWSER WINDOW: The browser is the type of software you use to view things on the internet (see above) – the browser window is the actual screen that the software displays everything on. If someone tells you to open a browser window, they are telling you to activate your browser so that an internet window opens up on your computer. You normally do this by clicking on an icon on your computer screen or task bar (at the bottom of your screen).

BROWSING: Going to different websites on the internet and looking around. A bit like window shopping, but on the internet instead of in a mall. Think of going into a bookshop and browsing. It’s the same thing. – Taking a casual look around for anything that may be of interest.

CACHE: Every time you do anything on your computer, it stores this in memory so that the next time you try to do the same thing, it happens quicker than having to wait from scratch. The place where it stores all this is called the "cache". The irony is that if your cache gets too full, it in fact makes your computer work a lot slower. It’s a good idea to empty your cache regularly to keep your computer working optimally.

CASCADING STYLE SHEETS: Also referred to simply as CSS, Cascading Style Sheets are used to define the look and feel of a web site outside of the actual HTML file(s) of the site. In recent years, CSS has replaced tables and other HTML-based methods for formatting and laying out websites. There are many benefits to using CSS but some of the most important are the simplification of a site’s HTML files (which can actually increase search engine ranking) and the ability to completely change the style of a site by changing just one file, without having to make changes to page content.

CATCHALL: This refers to an email folder that will catch any and all emails sent to your domain, even if there is no such address there. For example, you only have one email address on your domain, which is Now if someone sends an email to, the catchall will accept this email and store it, even though the address is invalid. Catchall’s used to be a great idea in case someone spelled you name incorrectly – you would still get the email. However, these days it’s a bad idea to use a catchall because spammers target these ferociously and you will end up collecting loads of junk that will either swamp your Inbox or cause your mailbox to become so full that legitimate emails bounce.

CC: Means "Carbon Copy". An email feature. Use this to send a copy of an email to one or many other people at the same time that you are sending it to the main recipient/s.

CHAT: In the context of the internet "chat" is a feature that allows users from all over the globe to communicate in real time or almost real time. Conventional chat is communication via typing which then appears on the recipient’s screen. This is done via a piece of software that exists on a server. In some cases you need to install complimentary software onto your own computer as well. Complete chat communities exist that allow people to join in on general conversations with many other users at the same time or with a single person at a time. These "meeting places" are referred to as "chat rooms". One on one chat can also take place privately by using a piece of software on your computer called a messenger. This has to be especially downloaded and installed from a website that uses this technology. Some of the more common, advanced chat facilities are provided by yahoo, msn and icq.

CMS: "Content Management System". A dynamic website that is normally database driven and which enables the owner/user to manage the content of their own website (make changes) without needing to know any coding at all.

CODE: Nothing that you see on the internet is what it appears to be. Everything is coded in one way or another to achieve the exact look, layout and functions. There are different types of code and coding languages that are used to develop websites as well as all computer programmes and software.

CONNECTION: This is what gets you going on the internet. Just like you cannot make a phone call without a telephone service provider to give you the use of their cables or towers, you cannot connect to the internet without an internet service provider to give you a connection to the internet. You get different types of connection: dial-up, ISDN, ADSL and wireless. Depending on the type of connection you choose, who you get your connection through and many other factors, you could end up with a slow or fast connection and a reliable or unreliable connection. However, not all connections are equal and no connection is necessarily the same from one day to the next or even one hour to the next. This is because of all the factors that can influence it. Some of these are: the equipment that your provider is using, the technical maintenance that they do, the software that they use, how busy the internet is at any given time, your physical location, the weather and even the condition of all of these things somewhere on the other side of the world.

CONTENT MANAGEMENT SYSTEM: Also known as a CMS, the content management system is a back-end tool for managing a site’s content that separates the content from the design and functionality of the website. Using a cms can make it easier to change the design of a site independent of the site’s content or pages. 
A content management system can also make it easier for pages and images to be added to the website for people who aren’t programmers, saving on the cost of hiring a programmer because you can add/edit/delete content yourself.

CONVERSION: A marketing term that refers to how many website visitors convert to buyers. If 1 out of every hundred visitors to a site end up buying something, there is a 1:100 (or 1%) conversion rate. Ultimately this is what website marketing is all about because it is pointless getting thousands of visitors if none are buying your product, your services, your ideas or whatever it is you are selling (every website is selling something, even if the only payment is an ego-boost to the site owner).

DATABASE DRIVEN: With a normal static website, the information that you see is on the page itself. It does not change unless someone manually edits the page. On a database driven website, the information is not stored on the page, but in a database. Every time someone visits a particular page, the information is drawn from the database in order to display it on the page. Information can therefore be easily cross-referenced and the same information applied in many different ways, using formulas and different variables.

DIRECTORY or SEARCH ENGINE DIRECTORY: Much like the Yellow Pages, a directory is a place where information about hundreds, thousands and millions of websites is stored to allow people to easily and quickly find information and/or resources. Yahoo is an example of a search engine directory, Trades Check for example is a directory website for people wanting to find local licensed tradesmen.

DOMAIN: A domain is a person or organisation’s unique space on the internet. In layman’s terms, it is commonly used to mean the name of your website.

DOMAIN NAME: A domain is identified by the number assigned to its unique space. To make it easier to use however, the number is given the name of your choice an this name is assigned to the number. In this way, people do not need to remember the number (IP) in order to visit a website, but can use the easier-to-remember domain name. This websites domain name is

DOMAIN NAME EXTENSION: Often referred to as Internet top-level domains (TLDs). The official list of all top level domains is maintained by the Internet Assigned Numbers Authority (IANA). Each country is designated an extension; Australia is .au, India is .in, United States of America is .us and not .com as most people think. The .com extension actually refers to commercial and is open for any entity or person to register, so a means a commercial extension in Australia. Some extensions are limited to certain groups such as .edu for educational institutions and .gov for governments.

DOMAIN REGISTRATION: In the same way that you have to register a business name, so you need to register a domain name. Only once it is registered do you have the ability to assign it to a specific number so that it has an actual location on the internet. A domain name registration is normally only valid for one or two years, at the end of which it has to be renewed for you to continue using it. Some domain names must be registered for 2 years minimum.

DOWNLOAD: When you transfer information from a website or server to your computer, this is called downloading. Collecting email is therefore a download, as is saving a document from the internet to your computer or installing a software programme directly from the internet. Every time that you visit a website you are also downloading, because the information is passing from the server to your computer and often saved there without you even knowing (see "cookies"). This becomes quite important if you are using something like ADSL to connect to the internet, where you have a limit on bandwidth because you use bandwidth every time you download anything. The bigger the download, the greater the bandwidth that you are using.

DNS: Stands for Domain Name Service (alternately Domain Name System or Domain Name Server). Basically, it’s the thing that converts IP addresses into domain names. DNS servers are provided with the IP address of your web server when you assign your domain name to those servers. In turn, when someone types your domain name into their web browser, those DNS servers translate the domain name to the IP address and point the browser to the correct web server.

DOCTYPE: The doctype declaration specifies which version of HTML is used in a document. It has a direct effect on whether your HTML will validate.

ELEMENT: A HTML element is everything from the start tag to the end tag. Using the p tag (

) as an example:

This is a paragraph


element has a start tag

and an end tag

with the element content being ‘This is a paragraph’. The

element defines a paragraph in the HTML document.

EMAIL: The internet equivalent to post and mail, email is an encoded message that is sent instantly to someone else’s computer. It is however a "best attempt" facility and not foolproof, largely because of the complexity of the internet itself and the vast number of things that can cause the process to stall or fail.

EMAIL CLIENT: The software programme that you use in order to send and receive email from your home computer, tablet or smart phone. All devices with Windows installed come with 2 email clients to choose from: Outlook and Outlook Express. I recommend people use Outlook for it’s functionality.

FAVICON: Favicons are tiny (generally 16×16 pixels, though some are 32×32 pixels), customizable icons displayed in the web address bar in most browsers next to the web address. They’re either 8-bit or 24-bit in colour depth and are saved in either .ico, .gif or .png file formats. The favicon used by Thinking IT is the head logo.

FIXED WIDTH LAYOUT: A fixed width layout has a set width (generally defined in pixels) set by the designer. The width stays the same regardless of screen resolution, monitor size, or browser window size. It allows for minute adjustments to be made to a design that will stay consistent across browsers. Designers have more control over exactly how a site will appear across platforms with this type of layout.

FOLD: The fold is a term carried over from newspaper design and pagination (where the fold referred to the physical fold in the paper). The fold in a website is the point on the web page that rests at the bottom of someone”s browser (in other words, to see anything below the fold, they would have to scroll down). There are varying opinions on how important the fold is in web design but more websites including Yahoo and msn are increasing their page length to get more information displayed on each page.

FONT FAMILY: Font family is a group designation for defining the typefaces used in CSS documents. The font family tag generally lists multiple fonts to be used, and usually ends with the generic font category (such as “serif” or “sans-serif”).

FREEWARE: Software that is made available at no cost whatsoever. Often includes advertising for the provider and is sometimes used to entice a user to purchase the unbranded version with no advertising. Freeware from an unknown or questionable source should be avoided as these programmes can contain viruses or adware (see "adware" above)

FTP CLIENT: The software programme that you use to upload your website to a host server.

GIF: A type of file used for images, especially animated graphics and line-drawn images (as opposed to photographs). A .gif image can be saved with a transparent background, making it ideal for graphic overlays.

HEXADECIMAL: Also referred to a “hex” numbers, they are a base-16 numbering system used to define colours online. Hex numbers include the numerals 0-9 and letters A-F. Hexadecimal numbers are written in three sets of hex pairs. Because screen colours are RGB (Red, Green, Blue), the first pair defines the red hue, the second pair defines the green hue, and the third pair defines the blue.

HIT: Contrary to popular belief, a hit does not represent a single visitor to a website. A hit is actually a request for a single file from your web server. This means one page can actually generate multiple hits, as each page generally has more than one file (an html or other base file, a css file, multiple images, etc.) and each one is requested from the server whenever the page is loaded. Some marketing people like to quote hits to unknowing consumers as the number makes their site sound like it”s getting a whole lot more traffic than it actually is.

HOST / HOSTING: In order for you to have an email address or a website, a computer somewhere, with all the necessary software, has to provide you with 3 things: an IP (domain) address, physical space to store the information and bandwidth that accommodates the flow of information that is taking place on your behalf. The company that provides you with these facilities is your host and you will pay them a fee for hosting your site and or email address.

.HTACCESS: The .htaccess file is the default directory-level configuration file on Apache servers. They are also known as “distributed configuration files.” Configuration directives contained in the .htaccess file apply to the directory in which the file is placed as well as all of its subdirectories. Within the .htaccess file things like authorization and authentication, rewriting and redirecting of URLs, cache control and customized error responses can all be specified.

HTML: Hyper Text Markup Language. This is the base language that s used for creating websites. Common uses of the term are, "html coding" and "html website". A website created in pure html is also referred to as a static website. In other words, it does not interact with the visitor other than in the most basic ways. It stores no data and can not return data other than what is consistently on the page itself. Emails that use different fonts, colours, borders, backgrounds and graphics are also generally coded in html, with the alternative being plain text.

HTTP: HyperText Transfer Protocol. This is a method used to transfer information on the internet and normally precedes the "description" of the actual resource being accessed and transferred. For example, web sites and web pages are one type of resource, identified by their domain name (

HTTPS: Similar to HTTP, HTTPS stands for HyperText Transfer Protocol over SSL (Secure Socket Layer) or, alternately, HyperText Transfer Protocol Secure. Like HTTP, it”s a set of rules for transferring hypertext requests between browsers and servers, but this time it”s done over a secure, encrypted connection.

HYPERTEXT: Hypertext is any computer-based text that includes hyperlinks. Hypertext can also include presentation devices like tables or images, in addition to plain text and links.

IE: Internet Explorer. The most commonly used internet browser in use, largely because it comes with Windows software and is the automatic default browser for any Windows user. The default can be changed to a different type of browser.

IFRAME: Short for Inline Frame. An iframe is used to display one or more web pages within another normal web page (one that isn”t a frameset page).

IP or IP ADDRESS: Internet Protocol. Very simply, the IP address refers to the actual number that a web address name translates to. (also see "domain"). The IP number is the real address.

ISP: Internet Service Provider. The company that provides you with internet access (connection) and related services is your ISP. Internode is very popular in Adelaide, South Australia

JAVASCRIPT: Coding languages used to achieve effects and functions on websites that normal html and its variants cannot achieve. These bits of coding (or scripts) are normally embedded into a web page and will automatically activate as soon as someone arrives on the page. Please note that JavaScript is distinctly different to Java.

JPG: A type of file used for images, especially photographs. Images used on web pages work best as jpg or gif.

KEYWORD or KEY PHRASE: An internet marketing term that refers to the main topics or subjects of your web pages in relation to how people would phrase them when searching for your products or services on the internet. For example, your topic may be "Quantifiable Analysis of the Strategic Business Model" but the average person searching for your exact information may simply search for "planning business strategies". Your key phrases are at the core of any website marketing strategy and needs to relate to your target market’s thinking rather than your own.

LAN: Local Area Network. A method of connecting a small network of computers to each other. Using LAN enables file sharing amongst different computers and the ability to connect multiple computers to the internet using the same connection.

LANDING PAGE: A landing page is the page where a visitor first enters a website. Oftentimes, a special landing page is created to elicit a specific action from the new visitor (usually in connection with an advertising or marketing campaign).

LIQUID LAYOUT: A liquid layout is one that is based on percentages of the browser window’s size. The layout of the site will change with the width of the browser, even if the visitor changes their browser size while viewing the page. Liquid layouts take full advantage of a person’s browser width, optimizing the amount of content you can fit on screen at one time.

MAILSERVER: (Also see "server"). A mail server is a computer that distributes email. Simplest is to think of it as an internet version of your local post office.

META DATA Meta data is the data contained in the header that offers information about the web page that a visitor is currently on. The information contained in the meta data isn”t viewable on the web page (except in the source code). Meta data is contained within meta tags.

META TAG: Included in the head section of an html web page and is visible to search engines but not human visitors. Meta tags provide information about a web page, like the topic (title), keywords, description and also instructions to search engine robots and visitor browsers.

OPERATING SYSTEM: The type of software that you use to run a computer is the operating system.

OPTIMISE: Has two possible meanings in web design. The first is website/page optimisation. This relates to how the page is structured (both code and content) with regard to search engines. A well optimised website is search engine friendly. The second meaning relates to graphics and pictures that are used on websites. An optimised graphic is one that has been compressed as far as possible without sacrificing acceptable quality. This allows the image to load more quickly when someone visits a website.

PARKED DOMAIN: A domain name that sits on the same server space as another. If someone types in the address of either the main domain or the parked domain, they will arrive at the same website.

PHP: A programming language that is Linux based rather than Windows based. Normally used for increased functionality on a website or to work with a database. It works in conjunction with html and html variants and allows for functions to be run from the server rather than the visitor’s browser.

PLUG IN: A plug-in is a bit of third party code that extends the capabilities of a website. It”s most often used in conjunction with a CMS or blogging platform. Plug-ins are a way to extend the functionality of a website without having to redo the core coding of the site. Plugins can also refer to bits of third-party software installed within a computer program to increase its functionality.

PPC: Pay Per Click. A common term in internet advertising where you purchase advertising space on someone’s website, but instead of paying a flat monthly rate, you pay a small amount each time someone clicks on your advert – which is a link that takes them to your website. This "small amount" can however go quite high, depending on the deemed value of the link. This is a very simplified explanation, but the principle is that you ostensibly "pay for what you get", which is not entirely accurate. False clicks can in fact make this much more expensive than a fixed advertising cost.

PROPAGATION: (Please first read about IP’s and domains if you are not already familiar with those terms). When an IP is changed because you have started up a new website or moved your website from one hosting company to another, every nameserver across the entire internet globally has to update its records to know where to find you. This process is called propagation and can take up to 48 hours. Sometimes even longer. This is because nameservers do not all update at the same time, some update more frequently that others and sometimes a nameserver can have a problem for a while. This means that some people can see the site and others can’t. Some emails will reach their destination and others won’t. Once domain propagation is completed however, everything should work as normal.

RANKING: Ranking is a term related to search engines. When someone searches for something using a search engine, the will receive pages and pages of results. Where a specific site appears in those results is its ranking. There is a second meaning as well, more commonly used with regard to marketing and SEO and related specifically to Google. Each page of a website is given a ranking by Google, from 1-10. This ranking is the value that Google places on that particular page in relation to its subject matter and how relevant it is. The more relevant a page is believed to be the higher its ranking.

REALLY SIMPLE SYNDICATION: Also referred to as RSS. RSS is a standardized XML format that allows content to be syndicated from one site to another. It”s most commonly used on blogs. RSS also allows visitors to subscribe to a blog or other site and receive updates via a feed reader.

ROOT: In the context used here, this relates to website hosting. Often when you want to install a piece of software to work on (or run) your site, you will need "root access". This means that you have access to your hosting space at the highest level. To explain further: the information on the server is stored in different folders, arranged in a hierarchical order. The main folder in which all the other folders and sub-folders for your account are kept, is the root folder. If you go into your account on the server and can only see the main content folders, then you do not have root access.

SCRIPT: A piece of code that creates or enables a specific function on a website. The possible uses are endless, as are the different types of scripts that can be used, written in a variety of languages, including JavaScript.

SEARCH ENGINE: A programme that collects, stores, arranges and normally ranks the various resources available on the internet. It is most commonly on a website and used to find other websites – much like the yellow pages is used in the brick and mortar world.

SEARCH ENGINE FRIENDLY: This relates to how well a site has been put together. A search engine friendly website is one that search engines can easily read and find all the links on AND which search engines "like" because it is properly optimised and not breaking any of their rules.

SEARCH ENGINE LISTING: When someone searches for something using a search engine, all the sites that are listed in response to that search have a "search engine listing".

SEARCH ENGINE RANKING: Different to a search engine listing because a listing means the site appears anywhere on the list. Ranking relates to exactly where on the list it appears. Closer to the top means it has a higher ranking. A critical consideration in having your website found on the internet.

SEARCH RESULT: When someone searches for something using a search engine, the list of websites and links that the search engine responds with is the search result. The aim of any website is to appear high in the search result.

SEO: Stands for "Search Engine Optimisation" and very simply refers to the practice of tweaking website coding and content to achieve the highest possible search engine ranking. SEO practitioners are people who specialise in this (or claim to).

SERVER: A server is a computer that is used to house websites and provide a physical storage area for websites and emails. Without a server, your website would not be viewable to the world. Servers are normally provided by hosting companies who keep the servers in special premises, under special conditions and with permanent connections to the internet.

SERVER SIDE: Server-side refers to scripts run on a web server, as opposed to in a user”s browser. Server-side scripts often take a bit longer to run than a client-side script, as each page must reload when an action is taken.

SHAREWARE: Shareware is a piece of software that you can use free of charge for a set period. After that you have to buy it or pay a license fee in order for the software to keep working. There are different types of shareware. With some you have limited use (not everything works) before you pay, with others you have full use but for a limited time. Some shareware has both limited use and limited time.

SITEMAP: This is an index to all the content on a website. It is normally accessible from at least the front page of the site and is used for two purposes: to help people find what they are looking for on the site and to help search engines find all your links.

SPAM: A somewhat controversial word which has different extremes of meaning to different people. Very simply, spam is junk mail, normally sent out in bulk and normally with no regard as to whether you want to receive it or not. Serious spammers will in fact use your protests as proof that you are seeing their emails and spam you even more.

STABLE RELEASE: While BETA software is software that is in the final testing phases, a stable release is when the software has passed the beta testing phase and is considered safe for general use.

SUBDOMAIN: A domain that is behind another, but totally separate. Using sub-domains you can effectively have multiple "domains" on a single registered domain name and hosting account. A sub domain address would be written like: The "something-else" is the sub domain.

TAG: A tag is a set of markup characters that are used around an element to indicate where it starts < > and ends Tags can also include HTML or other code to specify how that element should look or behave on the page.

THE NET: A shortened version of "The Internet". Refers to the entire network that exists worldwide, making communication and information accessible to anyone with a computer and connection.

TIMEOUT: If you try to connect to any server on the internet – to view a website or collect email – and it takes too long, you will have a time out. It purely means it has taken too long, so the process was aborted. This is often what has happened when you get an error while trying to send or receive email, or when you try to visit a website and instead get a page that tells you the site cannot be found. Often just trying again immediately fixes the problem.

TRAFFIC: Much like the physical world, traffic refers to all the people and computers that are using a particular route at a given time or who access a specific resource. The number of visitors to a website, for example, is also referred to as traffic. Traffic is also often spoken about when it comes to hosting. If a host tells you that you are allowed X amount of traffic, they are telling you how much of the server resources you are allowed to use. This is also called "bandwidth". Please see the explanation of "bandwidth" for more information about "traffic" in the context of hosting.
