Now day’s computer science become necessity for everybody  should be learn basic of computers.

Computer replaced physically space needed for large amount of documentation and file records with small memory storage space.

Computer Science Overview  

“It is a branch of science for theoretical foundation of computation, information and their implementation and application in a computer system”

Computer science has many sub-fields each studied as a separate subject:

Computer Graphics: Study of use of graphics in computer.

Programming Languages Theory: Specify to use language to solve computational problem.

Data Structure: Study of logical relationship among different element of a collection of data.

Computer Architecture: Study of that aspect of computer which influence a programmer.

In this world many types of computer are available for every field to fulfill user requirement. Computers broadly classified by their speed and computing power.

PC- personal computer: The personal computer (PC) define computer designed for general use by a single user. These computers are called personal computer (pc). The first computer was launched by IBM as IBM/PC. Nowadays, thousands of vendors are there which supply personal computers. Processing power of these computers is increase day by day, Cost is reducing. The operating system used by these computers may be Microsoft windows, Linux, Mac OS etc. present scenario Personal computers come in many forms, including the new Apple iPad.personal computer
