to store information. This disc can be read using a CD-ROM drive.

keyboard. A hardware device consisting of buttons
(keys) that the user presses to type characters into a computer.
laptop. A portable computer small enough to use

Memory. The computer uses this memory constantly
to temporarily store information, (or data), while it is working
with it. If a computer has a lot of memory, it can store more temporary
information and operate faster.
The microprocessor, (also called the central processing unit), is
the brain of the computer.
Modem. Modems change a computer's digital information
into analog waves that can travel through the phone lines to another
computer. The other computer's modem then changes the analog waves
back into digital information, so that the other computer can understand
it. Modems are rated by how many bits of information they can receive
in one second. Just because a modem is rated at 56Kbps does not
always mean that it is going to be able to receive at that speed.

RAM (random access memory). Random Access Memory
(RAM) provides space for your computer to read and write data to
be accessed by the CPU (central processing unit). When people refer
to a computer's memory, they usually mean its RAM. If you add more
RAM to your computer, you reduce the number of times your CPU must
read data from your hard disk. This usually allows your computer
to work considerably faster, plus able to open more than one program
at a time.
