a unique character or characters displayed by a program to in-
form the user that the program requires some instruction or in-
formation. In CP/M, the A> is a prompt which indicates that the
computer is waiting for the user to enter a command.
acronym for Random Access Memory: the memory that the
computer uses for short-term storage of information and pro-
grams.
Unlike ROM, the information stored in RAM is change-
able and volatile, meaning it will disappear when the power to
the computer is turned off.
acronym for Read Only Memory: the memory that is used for un-
changing information and programs. Information stored in ROM
is not volatile, and will remain intact regardless of whether the
power to the computer is on or off.
a portion of a hard disk which is reserved as a space to which
the read-write head can move when it has nothing else to do.
Also, the head must be moved to the safety zone before the
computer is turned off. This is done by typing after the A> prompt:
safety
a group of bytes on a disk. The standard KA YPRO double-
density floppy disk has 10 sectors on each track, with each sec-
tor containing 512 bytes of information.
a CP/M program that gives the statistics of a disk's files, show-
ing how
much space (in kilobytes) each file is using and how
much empty space is left on a disk.
a ring
of information on a disk. A double-density floppy disk has
40 tracks.
The
15 areas on a hard disk which are set up to hold files. They
have no
specific size, but adjust in size as necessary.
a program often used, particularly by system programmers. For
example, PIP is a utility program (details in the CP/M manual)
that allows the transfer of files.
