INTRODUCTION :
• Who invented the computer?
• What is computer?
• How did the computer evolve?
• Where did it start?
Charles Babbage, a British professor mathematics is the man who invented the first computer in 1837. It was basically an mechanical type of calculator that also had a memory. The computer was powered by steam engine and used punched cards for programming.
A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
The first modern computer was invented during World War II. It was invented by a team of scientist and engineers at the University of Pennsylvania. It was actually a general purpose digital calculator called the ENIAC.
The computer first started with a machine that could calculate math problems known as a calculator to us today, but known as the difference engine to Charles Babbage in 1833. The main purpose of the machine was to calculate astronomical tables. The machine was never built because the government ignored his ideas. In 1940 an idea of the Analytical machine, which claimed could perform any mathematical calculation. The machine was built but there were too many bugs and defects that made the machine incompatible of doing a lot of mathematics.
