MEMORY
Data is stored in the KAYPRO 10 by
means of:
•
ROM
(Read Only Memory)
• RAM (Random Access Memory)
• the hard
disk
ROM is the
smallest
portion
of
memory - about 4 kbytes (4,000 bytes).
ROM
contains
unchanging
programs and
information
most frequently used.
RAM
holds
64
kilobytes
(64
thousand bytes). RAM can be read from and
written
to. RAM is lost when the
computer's
power is turned off, so,
if
you want
to
save
a program
or
data
which
you have put in RAM, you
will
have
to
save it on the
hard disk.
The hard
disk
holds
10
million
bytes
of
information
that may be stored, retrieved,
changed, and erased, as necessary.
If the information you are storing has con-
tinuing
value for you, you will
want
to
back up the information which is on hard
disk
by copying the
information
to
a
floppy
diskette
.
