are created with CD writer. The speed of these drives is up to 52X or
more.
CD-RW - You must have a CD-RW drive to write date on the CD-RW. These
drives have read and write speed is up to 52X or more but the re-write
speed is 10X or more. The CD-RW drive is advanced and more expensive
than CD-R drive. It can write data on both CD-R and CD-RW discs and
also read data from them
DVD - DVD stands for Digital Video Disk Versatile Disc. DVD-ROM is an
extremely high capacity optical disc with storage capacity from 4.7 GB
to 17 GB.
TRANSFER RATES
Today CD-ROM drives have transfer rates or speeds ranging from 52X to
72X or more. For Example, a 52X CD-ROM drive has a data transfer rate
of 7,200 KBps (i.e. 48 X 150 = 7200)or 7.2 MBps. It means that the
higher the number, the faster the CD-ROM drive. This speed is
generally only going to be noticeable when installing a program or
copying large amounts of data from a CD.
PRICE RANGE
For a CD-ROM drive, not to be confused with a CD-R, CD-RW or DVD drive
can vary depending upon the speed and the interface the CD-ROM drive
uses.

Hard Drive
Hard drives have and always will be an important consideration to
think about when purchasing a new computer or used computer. Hard disk
is most commonly used storage device in personal computers and laptop
computers. Most application programs and operation systems require
hard disk for installation and operation.
Processor
The computer processor is and will always be an important
consideration when purchasing a computer. Processor is considered the
brain of the computer. The CPU fetches instructions of program from
main memory and executes them one by one. The speed of the CPU is
measured in Mega Hertz or Giga Hertz and speed from 500 MHz to 3.4
GHz, it depends upon a user needs, that is why purchasing a processor
is an important consideration when building or buying a computer.
There are several considerations and additional information about what
to ask and look for when purchasing a processor directly or already
