Sound cards are a physical component of
computers which convert digital information into
analog sound, which can be heard through
speakers.

Sound cards have output and input capabilities

Now a days they are rather popluar and they have
begun to become for many indiviuals an inessential
need

13. Video Card

Also called graphic cards, video
cards are a physical parts of
computers which are used to display
graphics on a monitor screen.

Almost used in every area beside
radios.

Because video cards will generate
heaps of warmth, most video cards
have a conductor.

Some also employ a fan to help with
cooling.

14. Motherboard

Motherboard knowns because the brain of a compture

The motherboard contains the connectors for attaching further
boards. Frequently, the motherboard involves the CPU, BIOS,
memory, mass storage interfaces, serial and parallel ports,
expansion slots, and all the controllers required to control regular
peripheral instruments, such as visual display unit, keyboard, and
disk pressure.

15. RAM

RAM stands for Random Access
Memory

A type of computer program tha can
be access randomly

RAM is hardware used to store and
retrieve information

RAM can access data much faster
then ROM, though RAM requires
power to keep the data accessible

16. ROM

ROM stands for Read-Only Memory

Like RAM, ROM is also hardware used to
store and access data.

ROM can only be read and not modified

Unlike RAM, ROM does not require power to
keep and access data

17. EPROM

EPROM stands for Erasable
Programmable Read-Only Memory is
programmable that can be erased and
resued.

Erasure is caused by shining an intense
ultraviolet light through a window that
is designed into the memory chip

Due to ultraviolet light clears its
contents, making it possible to reproram
the memory

The most frequent use for an EPROM
memory chip is to store pc BIOS.

18. Client

The client is a part of a client-server architecture. Often, a client is
an utility that runs on a private pc or workstation and relies on a
server to perform some operations. For instance, an electronic mail
client is an application that enables you to ship and receive e mail.

19. Email Address

A name that identifies an electronic post workplace box on a network
wherever e-mail is sent. Different varieties of networks have completely
different formats for e-mail addresses. On the Internet, all e-mail addresses
have the form:

@<domain name >

For example,webmaster@sandybay.com

Every user on the web contains a distinctive e-mail address. Th term e-
address is a symbol that is commonly used for e-mail address

20. CACHE

A cache is a place to store
something transitorily in a
computing environment. It's
pronounced CASH.

Is used to speed up the retrival
process in computer

In computing, active data is often
cached to abbreviate data access
times, reduce latency and
ameliorate input/output. Because
virtually all computer application
workload is dependent upon
input and output operations,
caching is utilized to amend
application performance.

21. CD ROM

CD ROM stands for Compact Disc-Read-Only Memory,

a type of optical disk capable of storing large amounts of data -- up to 1GB

A single CD-ROM has the storage capacity of 700 floppy disks

To read a CD, you need a CD-ROM player. Thats is installed in almost
every computer.

You can use cd to store or play videogame, audio, movie etc.

To add or store some data on the Cd Rom. You need Cd writer.Which are
used by many coftware industries.

22. DVD-RW

A DVD-RW disc is a rewritable optical
disc with equal storage capacity to a
DVD-R, typically 4.7 GB

Developed by Pioneer in November 1999

The primary advantage of DVD-RW(DVD
Writer) over DVD-R(DVD Read Only) is
the ability to erase and rewrite to a DVD-
RW disc.

One benefit to using a rewritable disc is if
there are writing errors when recording
data, the disc is not ruined and can still
store data by erasing the faulty data.

Data can thus be written, erased and re-
written.

23. Modem

Modem a device thats is used for computer to send the data to
other technology. For example Computer information is stored
digital form, whereas information transmitted over telephone lines
is transmitted in the form of analog waves.Which computer cannot
understand nor the data from the computer(understand only
didgital,not analog) to telephone(only understand analog, no
didgital). So to help them commuincate A modem is used, to
converts the waves or data between these two forms. From didtal to
analog, From analog to digital.Which help them communicate.

24. MP3

Stand s for MPEG-1 Audio Layer-3

MP3 is a lossy data compression format for audio

Is used to make smaller computer file containing digitale music
and other sounds.

Maintaing nearly the same Cd quality sound.

Because of its small size and pleasent reliability, MP3 files have
become a popular way to store music file both in computer in
phone like ipod etc.Which now are used to listen music

25. VIRUS

A computer virus is a program or piece
of code thats is that is loaded onto your
computer without your knowledge from
internet or anyother software that
download from internet and its runs
against your wishes on your PC.

Many virus that are used they make a
copy of thmselves consuming your
avaliable memory which brings the
system to halt. All computer viruses are
man-made.

An even more dangerous type of virus is
capbale of bypassing the security of a
computer maikng the computer unable
to block any virus.
