Computer

Computer It is an electronic device that is designed to work with Information. The term computer is derived from the Latin “Computare” which means “to calculate”. It cannot do anything without a program. It represents the decimal numbers through a string of binary digits.

History of Computer In 1642 Blaise Pascal (a famous French mathematician) invented an adding machine based on mechanical gears in which numbers were represented by the cogs on the wheels.

The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.

Features of Analytical Engine Analytical Engine 1833could store numbers powered by steam accurate to six decimal places

Evolution of Computer First Generation (1946-1959) Vacuum tube based Second generation (1959-1965) Transistor based Third generation (1965-1971) Integrated Circuit based Fourth generation (1971-1980) VLSI microprocessor based Fifth generation (1980-onwards) ULSI microprocessor(Artificial Intelligence) based

First Generation (1946-1959) Vacuum tube based Storage Device – Magnetic drum, 1 KB memory Software – Machine and Assembly language Application – Scientific and simple business systems

Second generation (1959-1965) Transistor based Storage Device – Magnetic tapes, disk, 100 KB memory Software – FORTRAN, COBOL, Batch operating system Applications – Extensive Business applications, engineering & Scientific research

Third generation (1965-1971) Integrated Circuit based Storage Devices – High speed magnetic cores, large disk, 1 MB memory Software – FORTRAN-IV,COBOL 68 Applications – on-line system, Database management system

Fourth generation (1971-1980) VLSI microprocessor based Storage – Semiconductor memory, 1000 MB disks Software – FORTRAN-77,PASCAL,COBOL 74 Applications – personal computers,graphics oriented system,

Fifth generation (1980-onwards) ULSI microprocessor(Artificial Intelligence) based Millions of transistors 64 bit Used Artificial Intelligence Software - C and C++, Java, .Net
