Introduction:
 Computer is a computing machine. It have makeover brain developed by human being. It can perform accurately beyond its limits. It has its own language and number system which is deferent of human being.

Invention:
 We could argue that the first computer was the abacus or its descendant, the slide rule, invented by William Oughtred in 1622.
 But    the   first    computer    resembling    today's   modern    machines    was the  Analytical   Engine,   a device   conceived   and  designed   by  British mathematician Charles Babbage between 1833  and 1871

Generation:
 1940   –  1956:   First   Generation   –  Vacuum   Tubes.   These   early   computers used vacuum tubes as circuitry and magnetic drums for memory. ...
 1956  – 1963:  Second Generation – Transistors. ...
 1964  – 1971:  Third Generation – Integrated Circuits. ...
 1972  – 2010:  Fourth Generation – Microprocessors.
 Artificial intelligence (current)
Classification:
Functional Organization
Computer has three main parts. They are……….
 Input device
ex: Key-board, Scanner, Mouse etc.
 Processing unit.
ex: Central processing unit
 Output device.
ex: Monitor, Printer, Projector etc.

Application of computer:
Computers  are  used  to control  large  and small  machines  which  in  the past were controlled by humans.
 Medical  and Patient  Data.  When examining  patients,  doctors  and nurses can take notes and prescribe treatments at the point of care. ...
 Medical Imaging and Equipment. ...
 Patient Monitoring. ...
 Research. ...
 Communication and Telemedicine. ...
 Inventory. ...
 Computers Made for Healthcare.

Advantage:
 Increase your productivity. ...
 Connects you to the Internet. ...
 Can store vast amounts of information and reduce waste. ...
 Helps sort, organize, and search through information. ...
 Get a better understanding of data. ...
 Keeps you connected.

Disadvantage:
 Unemployment.     Different     tasks     are     performed     automatically     by using computers. ...
 Wastage of time and energy. Many people use computers without positive purpose. ...
 Data   Security.   The   data stored   on a  computer   can be accessed   by unauthorized persons through networks. ...
 Computer Crimes. ...
 Privacy violation. ...
 Impact on Environment.

Completion:
End of the line we can say, computer can make our life more easy and relax able. Though there are some disadvantage but so many advantage we can achieve by properly using computer. To be a successful in our aim every body should learn and properly use the computer.
