Computers have become really advanced with wide
varieties of accessories attached to it. We can define an accessory as a device
which is attached to a computer but is not a part of it. The functionality of
an accessory depends on the computer it is attached to. A computer has to be
equipped with all the necessary computer accessories in order to carry out all
the tasks in more efficient way. There are two forms of accessories one is
basic accessories and other is an advanced accessories. Basic accessories available
are speakers, printers, scanners, UPS, surge protector, headsets, cases and
covers, cleaning and repair kits etc. Advance computer accessories include
webcam, microphones, gaming equipments, portable storage devices, CD and DVD
recordable drives, network accessories, modem.
These computer
accessories and Peripherals make each task very fast and easy for example
if you have a personal printer connected to your PC then there is no need to go
to any office to get the document printed. The most important computer device
is the UPS (Uninterrupted Power Supply), it provides a continuous power supply
to a computer so that no data should be lost. A Headset comes with a built-in
microphone so you can not only listen to music but also make a call from your
computer to other computer or phone. Webcam allows taking pictures or recording
your video or can be used to have a live chat with anyone through internet.
Portable storage devices like USB flash drives can be
used to transfer data. The capacity of these devices varies from 8 to 12
Gigabytes. Rewritable CDs and DVDs are also other source of transferring and
storing data. If above devices are not enough for transferring data then we can
also go for networking accessories such as LAN cables or modem. These
networking devices can be used to transfer data within a Local Area Network or
over internet.
