Glossary of Computer Terms <strong>for</strong><br />

<strong>Food</strong> <strong>Service</strong> Operators<br />

Backup A duplicate set of programs and data.<br />

Band width The amount of data that can be transmitted at one time.<br />

Byte A unit of storage equivalent to one character; data-storage capacities are usually given<br />

in megabytes (2 20 bytes) and gigabytes (2 30 bytes).<br />

Cache Storage allowing rapid access to data.<br />

CD-ROM [compact disk; read-only memory] A compact disk that can store a great deal<br />

more in<strong>for</strong>mation than a floppy disk.<br />

Central processing unit (PCU) The part of the computer where “thinking” takes place; “the<br />

brain.”<br />

Clock speed The speed with which a computer can process in<strong>for</strong>mation, measured in<br />

megabytes.<br />

Configuration The way the software and hardware are set up.<br />

Database A large compilation of data; this may be accessed in many ways but is not used <strong>for</strong><br />

calculation. A directory of food vendors, their specialties, phone numbers, and addresses could<br />

be a database.<br />

DBMS A database management system.<br />

Desktop publishing A more advanced type of Word Processing; it may be used to incorporate<br />

graphics and complex page layouts <strong>for</strong> publishing documents. In food service management, this<br />

type of software is used to produce menus, signs <strong>for</strong> postings, newsletters, brochures, and training<br />

aids.<br />

Disk A magnetic recording plate on which data are stored. A floppy disk, or diskette, can be<br />

held in the hand and is used <strong>for</strong> storing limited programs and data. A fixed disk, or hard drive,<br />

is permanently located inside the computer and stores much greater quantities of in<strong>for</strong>mation<br />

than a floppy disk. All dietary manager computer programs require the greater memory found<br />

on a fixed disk.<br />
