Early Computers: A History of Computing Computers are a part of our everyday lives, but about two decades ago, computers were just beginning to enter homes.Many people don’t realize what the computer evolved from, and the speed at which computer technology has taken to arrive to what it is today.
Generally speaking, computers can be classified into three generations. In 1943 an electronic computer name the Colossus was built for the military.
Each generation lasted for a certain period of time,and each gave us either a new and improved computer or an improvement to the existing computer. Other developments continued until in 1946 the first general purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built.
As a result of the various improvements to the development of the computer we have seen the computer being used in all areas of life.
It is a very useful tool that will continue to experience new development as time passes.
Inside the ENIAC were 1,500 relays, and 17,468 vacuum tubes.
These vacuum tubes consumed 200 kilowatts of electricity, thus causing it’s own circuits to fry. The problem was that the tubes within the ENIAC produced heat, and...The invention of integrated circuit brought us the third generation of computers.With this invention computers became smaller, more powerful more reliable and they are able to run many different programs at the same time.By using these cards he was able to calculate the United State Census.Hollerith’s Computer Tabulating-Recording Company changed its name in 1924 to International Business Machines, IBM for short.It was as important as Microsoft is the to the world of computing today.The main term that was used was, “IBM-Compatible.” A large movement in computer technology was the use of vacuum tubes.In 1937 the first electronic digital computer was built by Dr. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes which was used for processing.When this computer was turned on for the first time lights dim in sections of Philadelphia.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.
