Copy of The A-Z of Technology Terms

If you want to know what all those vague technology terms may mean or even if you are totally unaware of what they mean, here is our summary listing of the A-Z of technology terms.

Account
An account is an often used term to describe what rights a user has on a network or system such as an Internet Service provider (ISP). This will usually detail what "privileges" the user has.

Adobe Acrobat Reader (PDF Documents)
Acrobat Reader is software available through Adobe that allows you to view a PDF document (A document that does not allow editing). It can be downloaded free of charge from Adobe.

Analogue
Analogue is a conventional method of transmitting data. It is the method that standard telephones operate as distinct from digital which provides for greater quality and speed of transmission.

Application Service Provider (ASP)
A relatively new phenomenon, application service providers (ASPs) are Internet -based programs that provide specific functionality (i.e. e-mail, calendar, file storage, etc.) in most cases for a fee. The main benefit being that you do not have to buy a software licence and in essence, only pay for what you use.

Attachment
An attachment is a document sent with an email message. You can attach many types of files to an email but you should be wary of attaching large files as these can take a lot of time to download. If you have a large file you are best to compress the file using software such as Winzip. By attaching the file the receiver can edit or amend as required.

Back-end
The back-end is often used computer term that relates to that part of an application that performs an essential task not apparent to the user. It is often refers to the process end of applications.

Backward Compatible
Backward compatibility relates to superseded software that can relate to earlier versions. eg. MS Word v7.0 can read MSWord v6.0 files, so it is backward compatible.

Bandwidth
Bandwidth is the maximum amount of data that can travel a communications path in a given time, usually measured in seconds.

Bookmark
A bookmark is a saved link to a Web page that has been added to a list of saved links. Microsoft Internet Explorer denotes these as "favourites."

Boolean Operators
Most search engines (eg. Looksmart) allow you to limit your search or make it more specific by using words like "And," "Or," and "Not." These words are known as boolean operators because of their origin as terms in logic.

Boot (re-boot)
To load and initialise the operating system on a computer. Basically, this is starting up your PC. To reboot is to turn the PC on again in Windows you use the CTRL+ALT+DEL keys as a "soft" boot. This means that you restart the PC rather than turn it completely off and on as this can cause damage to your PC's hard disk.

Bounce Back
An electronic mail message that is undeliverable and returns an error notification to the sender is said to "bounce back". Check that you have typed the address correctly.

Broadband
Broadband is a type of communication where a single wire can carry more than one type of signal at once, from audio to video frequencies. Cable TV (eg. Foxtel) is one technology that uses broadband data transmission.

Browser
A software program that allows you to surf the Web. The most popular web browsers are Netscape Navigator and Internet Explorer.

Cache
When you download a web page, the data is "cached," meaning it is temporarily stored on your computer. The next time you want that page, instead of requesting the file from the web server, your web browser just accesses it from the cache, so the page loads quickly. The one downside to this is that if the website you have cached is often updated you may miss the latest "version". If this occurs you can use the refresh button on your browser.

Chat Room
An electronic space, typically a website or a section an ISP where people can go to communicate online in real time. Chat Rooms are generally devoted to a particular interest or topic.

Defragment
A fragmented file or folder is split up into many pieces and scattered over the storage capacity on your hard drive. This means that it takes a lot longer to load and process files. A regular defragment will ensure that files are stored more logically and will help speed up processes.

Dial Up Account
