Before a disk can be useful in a computer, the disk must be formatted. Formatting, also called initializing, organizes the storage area on the disk-it magnetically marks the disk with tracks and sectors, each with indicated boundaries, so that the information you store can later be located easily. The process involves erasing all that is on the disk, testing the disk to make sure all of its sectors are reliable, and creating a directory-an internal address system used for locating information later.

Analog is the opposite of digital, and I can only explain analog in relation to digital. Analog refers to things that are in a continuous flow or that have an infinite number of values-things that are "analogous" to real life.

CD-ROM (pronounced "see-dee rom") stands for compact disk, read only memory. A NON-VOLATILE OPTICAL DISK STORAGE medium based on the same physical disk format as the audio Compact Disc (CD), developed by Philips and Sony. A CD-ROM actually looks just like the CDs we play music with. To use one with your computer, you need a CD-ROM player, also called a CD-ROM reader. A CD-ROM can hold up to about 600 megabytes of information, which is the equivalent of about 700 regular floppy disks. There are CD-ROMs that hold the entire works of Shakespeare, complete dictionaries, histories, images of the works in the Louvre, etc., etc., ete. You can search the CD for the particular information you want to work with, copy it, then paste it into your own documents on your hard disk to do with what you will. You can only read from a CD-ROM, though-you can't store information onto it. The biggest complaint about CD-ROMs is that they are relatively slow.

SCSI (pronounced "scuzzy," not "sexy") stands for small computer systems interface. SCSI is a standard for interfacing, or connecting, personal computers to peripheral devices (like scanners, hard disks, or CD-ROM players) and having them send information to each other.

Computer products go through extensive testing before they can be released to the unsuspecting and trusting public. When a product has passed the in-house testing stage (see alpha testing), it goes into beta testing, often just called beta. Beta versions of the product are sent out for beta testing to "normal" people who don't work for the company. (These people are then, logically, called beta testers or beta sites.) The beta testers work with the software or hardware in real-life situations and report back the things that go wrong or that need improvement.

Biometrics: The measurement of parts of a person's body, for example fingerprints, voice timbre or unique patterns in the iris of the eye, to identify the person for security purposes. Computers can now process such data sufficiently fast for biometric methods to be used in real time as keys to gain access to a system. For example, when a finger is placed on a scanning pad, the print is immediately compared with one stored in a database of authorized persons.

Beep is the generic term for whatever sound a computer makes when it's trying to tell you something. If you press the wrong key or click on something you shouldn't, the computer will beep at you. Sometimes it beeps just to let you know that it has started or finished doing something (like copying a file). You can customize the beep sound in some computers. In particular, newer Macs and pcs with Windows 3.1 come with several sounds you can assign to various types of "events" in the system. Hundreds can be added, and you can even make your own sounds.

Cylinder The set of all the TRACKS on a HARD DISK drive with multiple PLATTERS that may be read at the same time. All the tracks are the same distance from the central spindle, so they can be imagined as tracing a cylinder in space. The HEADS on all the platters move together in a parallel motion - a sequence of data stored within the same cylinder can be read at optimum speed without requiring any movement.
