23) Analogue: Signal whose value varies continuously over time. For example, when a person speaks, the sound wave is an analogue signal, varying smoothly as they talk. Analogue signal information differs from digital signals, which move sharply between fixed values. To help visualise this, consider the difference between an analogue watch face with sweeping hands and a digital watch display, which jumps from one number to the next.

Back upThe process of copying your important computer files and documents from your hard disk to removable media (such as Zip or CD-RW discs) or another computer, to protect against loss of the originals.
46) Banding: Noticeable stripes appearing on a print-out ? usually only a problem with inkjet printers.
47) Bandwidth: In computing terms, a measure of the maximum amount of data that can be transferred over a connection at any one time. For example, if you connect to the internet using a modem, then the bandwidth is likely to be up to 56Kbps (or 56,000 bits of data per second).
48) Beta: Version of a software application or system still in development. Companies make beta versions available to selected testers for evaluation, testing and feedback.
49) Bi-directional: Refers to an ability for two-way communication. Most printer cables, for example, are bi-directional, so the computer can send data to the printer and the printer is able to respond with print-job progress information.
50) Binaries: Newsgroup postings of encoded files (photographs, sound files, video clips and so on), rather than plain text. These are frowned upon except in certain groups, such as those beginning 'alt. binaries. '.

~~~ Computer terminologies 3 ~~~
1) Clock speed: Term used to describe the speed of a computer processor, measured in megahertz or, increasingly, gigahertz ? 700MHz or 1GHz (1,000MHz).
2) CMOS: Stands for complementary metal-oxide semiconductor, and pronounced cee-moss. This is a special computer chip that looks after system set-up information, like date and time and so forth.
3) Command prompt: Also known as DOS prompt. The Windows environment lets you point and click to navigate your way around the computer. However, the predecessor to Windows, DOS (disk operating system) requires typed in commands to control the PC ? and these are entered at the command prompt.
4) CompactFlash: Matchbook-size memory cards with no moving parts. These slot into various devices to store data. Popular with digital cameras and handheld computers.
5) Compression: To reduce the size of a file by encoding the data. This is useful for storing files which would otherwise take up lots of disk space, such as picture and video files. Compression also reduces transfer times, meaning files can be sent over the net, or to another disk, more quickly.
6) Configure: To tweak the functions of software or hardware to the particular settings you require. For example, Windows can be configured so that it displays a particular colour background, or so that it uses a larger typeface
