Data is stored optically on the surfaceof the disk.
CDD have become the predominantremovable storage media for PCs andcan store 700 Mega bytes of data.
A 4-pin cable from the power supplyplugs into the CDD and providespower to it.
Data to and from the motherboard iscarried on a 40-pin IDE(Integrated
Drive Electronics) cable.
There are two types of Compact DiskDrives available for PCs
1. CD-ROM(read only memory) is theolder type. It can only read CDs.
2. CD-RW(Rewritable) units can readand write CD-R and CD-RW typedisks.

It is powered by a 4
conductor cable coming
from the power supply.
Data to and from the
motherboard is carried on a
40-pin IDE(Integrated Drive
Electronics) cable.
Data is magnetically onmultiple rigid disks that are
stacked up like pancakes.

It is powered by a cable with a 4-
pin connector that comes from
the power supply.
It transfers data to and from the
motherboard by means of 34 pin
ribbon cable.
It stores data magnetically on a
removable floppy disk.
Floppy disk hold 1.44 Mbytes,
which at one time was a large
amount of data.

The keyboard was the first inputdevice developed for the PC.
Keyboard layout provides 104
keys organized as four groups:
1. Alphanumerical keys(A-Z;0-9)
2. Location keys(home, end etc)
3. Numeric keypad
4. Function keys(F1-F2)
Data is transferred to the PC overa short cable with a circular 6-pinMini-tin connector that plugs intothe back of the motherboard.

The motherboard is the
main component inside the
case. It is a largerectangular board with
integrated circuitry that
connects the rest of the
parts of the computer
including the CPU, the
RAM, the disk drives(CD,DVD, hard disk, or any
others) as well as any
peripherals connected
through the ports or the
expansion slots.

System software helps to run the computerhardware and computer system. It includesoperating systems, device drivers, diagnostictools, servers, windowing systems, utilities andmore.
The purpose of system software is to insulate theapplications programmers as much as possiblefrom the details of the particular computer
complex being used, especially memory andother hardware features, and such as accessorydevices as communications, printers, readers,displays, keyboards, etc.

Application Software allow end users to accomplish
one or more specific (non- computer related) tasks.
Typical applications include industrial automation,
business software, educational software, medicalsoftware, database, and computer games.
Businesses are probably the biggest users of
application software, but almost every field of human
activity now uses some form of application software.
