TECH A-Z

 Adobe Acrobat Reader
Acrobat Reader is software that allows you to view a PDF  document (a document that can be seen but not changed).  It can be  downloaded free of charge from Adobe.  


ADSL
Asymmetric digital subscriber line (ADSL) is a type of digital  subscriber line (DSL) broadband technology that is used to connect to  the Internet. It uses standard telephone lines to deliver high-speed  data communications (up to 24 megabytes per second).

 

Analogue
Analogue is a conventional method of transmitting data. Standard  landline telephones use analogue technology. It is distinct from  digital technology, which provides for greater quality and speed of data  transmission. 


Assistive technology
Assistive technology refers to any software or hardware that  acts to assist and improve the functional capabilities of people with  disabilities.  Examples include wheelchairs, prosthetics, voice-to-text  technology and text-to-speech technology.  


Attachment
An attachment is a document sent with an email message. Many  types of files can be sent this way (e.g. Word documents, PDFs, Excel  files, JPEGs). Be wary of attaching large files because these can take a  lot of time for the recipient to download.  If you have a large file,  it is considered good practice to compress the file using software such  as Winzip before attaching it.


Backward compatible
 If software is backward compatible, it is compatible with  earlier (superseded) versions of the same software. For example, the  Microsoft word-processing program Word 2010 can read files created in  the 2003 version of the same program, so it is backward compatible.  


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


Bit
 A bit (short for binary digit) is the smallest unit of measurement in computing.  8 bits make up 1 byte.  


Bluetooth
 Bluetooth is a wireless communications technology intended to  replace cables. It allows short-range connections between two or more  Bluetooth-compatible devices such as mobile phones, tablets, headsets or  medical equipment.  


Bookmark
 A bookmark is a saved link to a particular Web page.  Microsoft Internet Explorer denotes bookmarks as "favorites."  

 

Boot (re-boot)
To boot (or re-boot) is to load and initialize the operating  system on a computer. Think of it as starting up your computer. In  Windows you can use the key combination CTRL and ALT and DEL as a "soft"  boot. This means restarting the computer rather than turning it  completely off and on again, which could cause damage to your computer's  hard disk under some circumstances. 


Bounce back
 An email message that cannot be delivered and returns an error  notification to the sender is said to "bounce back". If you receive such  an error notification, check that you have typed the address correctly.   


Broadband
 Broadband is a type of communications technology whereby a  single wire can carry more than one type of signal at once; for example,  audio and video. Cable TV is one technology that uses broadband data  transmission.  


Browser
 A software program that allows you to surf the web. Popular web  browsers include Google Chrome, Mozilla Firefox, Microsoft Edge and  Internet Explorer.  


Cache
 When you download (read) 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 downside to this is that if the cached web page is often updated,  you may miss the latest version. If you suspect that the web page you're  seeing is not the latest version, use the "refresh" button on your  browser.   

 

CAD
Computer-aided design (CAD) is a type of software that allows  users to create 2D and 3D design and modelling. CAD is used by  architects, engineers, artists and other professionals to create precise  technical drawings. 


Chip
 A chip is a microprocessor that performs many functions and  calculations that make your computer run.  Your computer's chip is also  referred to as the CPU (Central Processing Unit) or the processor.  


Cloud computing
Cloud computing refers to the storing and accessing of data and  programs over the Internet instead of on another type of hard drive.  Examples of Cloud services include iCloud, Google Cloud and Dropbox. 


Compression
 Compression is the reduction of the size of a file.  Compressed  files take up less memory and can be downloaded or sent over the  Internet more quickly.  


Content
 Content refers to a website's text and information, as opposed to its design and structure.  


Cookie
 A piece of code or data created by a web server and stored on a  user's computer.  It is used to keep track of the user's usage patterns  and preferences.  


CPU
 The central processing unit (CPU) is the brains behind your  computer.  The CPU is responsible for performing calculations and tasks  that make programs work.  The higher the speed of a CPU, the faster the  CPU undertakes the calculations and tasks.  


Cybercrime
 Cybercrime is any type of illegal activity that is undertaken  (or relies heavily) on a computer.  There are thousands of types of  cybercrime, including network intrusions, identity theft and the  spreading of computer viruses.

Megahertz
 Megahertz is the unit used to measure the speed of a computer's processor (e.g. 2.8Ghz)  


Modem
 A modem is a device that allows computers to transmit information to each other via ordinary telephone lines.

 If a computer (or computer user) is online, it is currently  connected to a network or to the Internet. Online also refers to  resources and services available on the Internet - e.g. online banking,  online dictionary.  


Operating system
 An operating system (OS) is the software that manages all of a  computer's processes and allows programs and applications to run. The  most prominent operating system is Microsoft Windows. Others include Mac  OS X and Linux.  


PDF

RAM
 Random access memory (RAM) is usually referred to as a  computer's "memory" - it stores information used by programs. Generally,  the larger your computer's RAM, the more programs it can run at once  without slowing down.  


Read-only
 A read-only file cannot be edited, modified or deleted.
