| 2CPU |
The part of a computer
which controls all the other parts. Designs vary widely
but, in general, the CPU consists of the control unit, the
arithmetic and logic unit (ALU) and memory (registers,
cache, RAM and ROM) as well as various temporary buffers
and other logic. |

| 3RAM |
A data storage device
for which the order of access to different locations does
not affect the speed of access. This is in contrast to,
say, a magnetic disk, magnetic tape or a mercury delay
line where it is very much quicker to access data
sequentially because accessing a non-sequential location
requires physical movement of the storage medium rather
than just electronic switching. |

3.5" Floppy Drive |
A peripheral device
that reads and writes hard disks or floppy disks. The
drive contains a motor to rotate the disk at a constant
rate and one or more read/write heads which are positioned
over the desired track by a servo mechanism. It also
contains the electronics to amplify the signals from the
heads to normal digital logic levels and vice versa. |

| 12 NIC |
A body that provides
information, assistance and services to network users.
These will typically include telephone and electronic mail
"help desk" type services for users and network
information services such as hostnames and addresses which
are accessed automatically by computers using some
client-server protocol |

| 13 Modem |
An electronic device
for converting between serial data (typically EIA-232)
from a computer and an audio signal suitable for
transmission over telephone lines. In one scheme the audio
signal is composed of silence (no data) or one of two
frequencies representing 0 and 1. |

Card |
A plug-in optional
circuit card for an IBM PC. It provides high-quality
stereo sound output under program control. A
"multimedia" PC usually includes a sound card.
One of the best known is the Sound Blaster. |

| 15 Monitor |
A cathode-ray tube and
associated electronics connected to a computer's video
output. A monitor may be either monochrome (black and
white) or color (RGB). Color monitors may show either
digital color (each of the red, green and blue signals may
be either on or off, giving eight possible colors: black,
white, red, green, blue, cyan, magenta and yellow) or
analog color (red, green and blue signals are continuously
variable allowing any combination to be displayed).
Digital monitors are sometimes known as TTL because the
voltages on the red, green and blue inputs are compatible
with TTL logic chips. |
