Spectrum Chart - 134 : Computer Parts
CPU – A Central
Processing Unit (CPU) is an important part of almost every computer.
The CPU sends signals to control the other parts of the computer. It
is called as a brain of computer.
SD Card – A Secure
Digital card (SD card) is a kind of memory card. Such cards are
often used to store images or data. The card has a rectangular
design, but one edge is chipped off. This means that the cards
cannot be inserted the wrong way.
External Hard Disk -
External hard disk usually are used in addition to internal hard
drives in order to store more data. A portable or external hard disk
allows the user to back up or store important information separate
from the main internal hard drive. External hard disk is that it is
portable and operates on a plug-and-play basis.
Pen Drive - Pen drive is a
popular way to store digital information. Pen drives are an easy way
to share data (information). A pen drive can be attached to a USB
port and provides a certain amount of storage space, which can be
used to store data.
Speakers - Computer
speakers are speakers external to a computer. Speakers contain
amplifiers which vibrate to produce the sound. They come in many
different forms. Some speakers are already attached to a computer.
Some speakers are wireless. They work by Bluetooth.
Keyboard – A computer
keyboard is an input device that allows a person to enter symbols
like letters and numbers into a computer. It is the main input
device for most computers. A keyboard is most commonly attached to a
computer via USB port.
Mouse – A computer mouse
is an input device that is most often used with a personal computer.
Moving a mouse along a flat surface can move the on-screen cursor to
different items on the screen. Items can be moved or selected by
pressing the mouse buttons called clicking.
CPU Processor – CPU
Processor reads data from memory and write data to memory.
Processors today can do more than 1 billion (1,000,000,000)
instructions in a single second. The speed that a processor works at
is measured in hertz (Hz). Modern processors often run so fast that
gigahertz (GHz) is used instead, which means a billion cycles per
second.
Hard Disk - Hard Disk is
used by computers to store information. Hard disks use magnetic
recording to store information on rotating circular platters. The
capacity of a hard drive is usually measured in gigabytes (GB),
however hard disc capacity can also be measured in terabytes when
the capacity is over 1000 gigabytes.
RAM - Random access memory
or simply RAM is the memory or information storage in a computer
that is used to store running programs and data for the programs.
Data in the RAM can be read and written quickly in any order.
Normally, the random access memory is in the form of computer chips.
Scanner – A scanner is a
device used to transfer images or text into a computer. In the
computer, the signal from the scanner is transferred to a digital
image. This image can then be edited, printed etc.
Printer – A printer is a
piece of hardware for a computer. It allows a user to print items on
paper, such as letters and pictures. Mostly a printer prints under
the control of a computer. Inkjet printers, Laser printers,
Dot-matrix printers are common computer printers.
Ink Cartridge – An ink
cartridge is a small container that contains ink. The manufacturers
of Inkjet printers use special cartridges for their printers. There
may be one cartridge per colour. Sometimes, there is also just one
cartridge for several colours.
Plotter – A plotter is a
kind of printer for computers. Plotters use vector graphics. Usually
they are used to print to paper which is very large in size.
Plotters print things using special, coloured pens. Plotters are
generally used for making flex or maps.
Desktop - A desktop
computer is a personal computer designed for regular use at a single
location on or near a desk or table due to its size and power
requirements. Demand for desktop computers declined with the
introduction of laptops.
Mother Board – The
motherboard or main board is the main circuit board in a computer. It
is the most 'central' part of a computer. All of the different parts
of the computer are connected to the motherboard. This lets them
work together. In most computers, the motherboard is a big green
board.
Laptop – A laptop is a
computer which is easy to carry around. Its user can fold the laptop
along its hinge for carrying. The laptop was created mainly for this
particular reason. Computer parts were scaled to smaller size so
this could happen.
Tablet – A tablet
computer is a personal mobile computer which is used most of the
time by tapping with a finger or a stylus on a touch screen. It is
bigger than a mobile phone but smaller than a laptop.
Graphic Tablet – A
graphics tablet is a computer input device which replaces
hand-drawing. Users can draw directly to computer as if they were
drawing on a paper or any other material. These tablets are also
used to subscribe some documents or to capture handwriting.
Monitor – A computer
monitor is an electronic device that shows pictures. Monitors often
look similar to televisions. Monitors often have higher display
resolution than televisions. A high display resolution makes it
easier to see smaller letters and fine graphics.
Power Supply Unit – The
desktop computer power supply changes alternating current from a
wall socket to low-voltage direct current to operate the processor
and peripheral devices. Most modern desktop personal computer power
supplies conform to the ATX specification, which includes form
factor and voltage tolerances.
Power Cable – Power cable
is one or more wires covered in a plastic covering that connects a
computer to a power source or other device.There are two main types
of computer cables, a data cable and a power cable. A data cable is
a cable that provides communication between devices.
Graphic Card – Graphic
Card is a special circuit board that controls what is shown on a
computer monitor and calculates 3D images and graphics. A graphic
card can be used to display a two-dimensional (2D) image like a
Windows desktop, or a three-dimensional (3D) image like a computer
game.
CD/DVD – A Compact Disc
(CD) is a type of optical disc. It is flat and round, and is used to
store digital data. A DVD is an optical disc capable of storing up
to 4.7 GB of data, more than six times what a CD can hold.

between computer networks. They are responsible for making sure
traffic between computers gets where it needs to go. They do this by
choosing the shortest path between the computers using a complicated
system of rules called Routing Protocols.
Wireless Router – A
wireless router is a device that performs the functions of a router
and also includes the functions of a wireless access point. It is
used to provide access to the Internet or a private computer
