DEFINITION
• What is a Computer?
• com·put·er
Pronunciation key (km-pytr)
n.
• A device that computes, especially a
programmable electronic machine that performs
high-speed mathematical or logical operations or

processes information.

THE LANGUAGE OF
COMPUTERS
Binary Numbers
Binary Numbers 1 of 3
Computers speak binary. Binary language consists of combinations of 1's
and 0's that represent characters of other languages (in our case the
English language). Don’t make the mistake of thinking that little 1's and
0's are running around inside of the computer. We humans prefer to think
of 1's and 0's because it’s easier than visualizing positive and negative
current flows or open and closed circuits which is what actually happens
inside computers. A combination of eight bits represents one character in
our language. One character in our language (eight bits) is referred to as
a byte. (For example: 01000001 is a byte that represents an uppercase A;
each 1 or 0 is a bit.)
Binary Numbers 2 of 3
• Kilobytes, Megabytes, and Gigabytes
• If you understand that a byte is one character in
our language, you’ve got it made because:
• 1000 bytes = 1 kilobyte
• (1,000 characters = 1 kilobyte)
• 1,000,000 bytes = 1 megabyte
• (1,000,000 characters = 1 megabyte)
• 1,000,000,000 bytes = 1 gigabyte
(1,000,000,000 characters = 1 gigabyte)

Disk Capacity
It’s important to know how large your files are because eventually you won’t
have enough space on your disk to hold more files. Knowing the total
capacity of your disk, how much space is left on your disk, and how large the
file is, you can make accurate decisions as to whether to save the file to the
current disk, or save the file to a different diskette with more disk capacity.
Keep in mind that a low density floppy diskette holds 720 kilobytes of data,
and a high density floppy diskette holds 1.44 megabytes of data. Put in
easier to understand terms, a low density disk can hold approximately 300
typed pages and a high density can hold approximately 600 typed pages. Zip
disks have 100 megabytes of disk capacity (about $10.00 each) or 250
megabytes of disk capacity (about $15.00 each). CD-ROMS have 650
megabytes of capacity (about $1.00 each) or 700 megabytes of capacity
(about $1.50 each). Super Disks have 120 megabytes of disk capacity
(about $12.00 each). Hard drives (disk drives inside of the computer) might
hold anywhere from 30 megabytes (old computers) to 80 gigabytes (new
computers) of data. Most computers today are sold with anywhere from a 5
gigabyte (portable/laptop computers) to a 120 gigabyte (desktop computers)
disk capacity.

SYSTEM COMPONENTS
CPU/PROCESSOR
• The CPU refers to the microprocessor
chip. Sometimes the “Tower” is called the
CPU.
• It’s speed is measured in Megahertz
(MHZ) (Millions of cycles per second) or
Gigahertz (GHZ) Billions of cycles per
second.
• (A cycle is the time required for the CPU to execute
an instruction step).
SYSTEM COMPONENTS
Ram – Random Access Memory
• Ram is the memory used by the computer
to run programs.
• The amount of Ram available will
determine how fast a program will run and
how many windows can be open at one
time.
• Ram memory is considered Volatile
because it disappears when the power is
turned off.
SYSTEM COMPONENTS
Hard Drive
• The Hard Drive is the computers main,
long term storage.
• It is referred to as non-volatile storage,
because it does not disappear when the
power is turned off.
• The size of the Hard Drive is measured in
Gigabytes. (Billions of Bytes).
RAM VERSUS HARD DRIVE
• If we use the analogy
of a desk: Then the
work we are doing on
the desk top would be
using the RAM and
the work we store in
the file drawers would
be on the HARD
DRIVE.
SYSTEM COMPONENTS
• Mother Board
