(also called high speed) Internet access—typically contrasted
dial-up access over a modem.
A wire used to carry electricity.
caps lock. A key on the keyboard that capitalizes
all letters when pressed.
CD-ROM drive (Compact Disc-Read Only Memory).
The component that reads information from the CD-ROM.
Chipset. The chipset is the chip, or set of chips,
that direct the motherboard's flow of information from one point
to another. Just like a traffic cop, they make sure that the information,
(also called data), arrives at the proper place.
room. A virtual room used to communicate in real time with
compact disc (CD). A digitally encoded disc used
to store information. This disc can be read using a CD-ROM drive.
computer. A machine that stores and reads information.
computer case. It protects all of the electronic
components inside and must provide adequate ventilation to prevent
computer virus. A destructive code that spreads
from computer to computer, capable of damaging software.
CPU (central processing unit). The microprocessor.
The “brains” of the computer.
delete. A key on the keyboard used to delete characters
to the right of the cursor.
Drive Bays. Drive bays are where the computer's
drives are installed. For example CD-ROM and DVD-ROM drives.
(electronic mail). The exchange of messages using computer
enter. A key on the keyboard used to complete a
command or move down to the next line.
fan. The primary source of cooling for your computer.
fax machine. A device used to send and receive
data using telephone lines.
floppy disk 3.5”. A magnetic disk on which
data such as music, text, or graphics are magnetically encoded.
floppy drive. The component that reads and writes
to floppy disks.
forum. An online place to discuss particular topics.
graph. A diagram used to represent data.
hard drive. The component that reads and writes
data. It stores information.
(old computers are IDE and new computers are SATA)
HTML (hypertext markup language). A programming
language used to create documents to be viewed on the Internet.
IDE cable (integrated device electronics). The
cable that connects the drives to the motherboard. (new computers
use SATA cables)
Internet. A worldwide network connecting millions
instant messaging. Messages are electronically
exchanged with another person using usernames.
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
on one’s lap.
line graph. The type of graph in which lines are used to connect
modem. This device transforms a computer’s digital data into
analog data for transmission over phone lines, then reconverts the
data to digital. (dial-up – 56K)
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.
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.
A video display that takes signals from a computer and displays
information onto a screen.
motherboard. The computer’s main circuit
board. This connects together and enables the operation of all the
components of the computer. The heart of the computer.
mouse. A hand-operated data input device that moves
the cursor on a computer screen.mouse pad. A flat pad, coated with
foam rubber, designed to provide an optimum surface on which to
use a mouse.
multi-media. The integration of text, graphics,
sound, and animation on a computer.
netiquette. The term for appropriate behavior on
network. Two or more computers connected with wires
that have the ability to communicate.
network card. A circuit board used to connect the
computer to a local area network (LAN). (Ethernet – high speed
PCI slot/bus (Peripheral Component Interconnect).
A slot on the motherboard used to add PCI expansion cards.
pie chart. A chart in which a circle is divided
into sections, and each segment represents certain data.
plagiarism. To copy a piece of writing and use
it as your own.
power supply. The component that supplies power
to your computer.
printer. A device that prints text or graphics
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.
router. A router allows connectivity to one or
more computers, helping create a network. For home users, these
are particularly useful for taking a single broadband internet account,
and spreading it to at least two or more computers. Wireless routers
have become more common. A wireless router does exactly the same
job in the home as a regular wired (Ethernet) router, with the difference
that a computer can be connected to it without needing to run Ethernet
cable between the computer and the router. All you need is a wireless
network adapter in each PC you want to connect, usually in the form
of a card in your PCI slot (or a laptop's PCMCIA card slot) or an
adapter for USB.
search engine. A Web site designed to search the
Internet for a particular topic.
shift. Press and hold this key, then press another
key to make a capital letter or special character.
software. A program designed for use on computers.
An example would be Microsoft Word.
