The computer was first invented in 1822 which was originally only used as a quick calculator called the difference engine. Stealth in 1833 Charles Babbage developed another difference engine with a more in-depth and general concept. This machine can carry out any calculations, so this is the first machine known as a general purpose digital computer called the analytical engine.
In 1937, Prof. Howard Aikem, began designing and developing the manufacture of a computer that can perform arithmetic and logic operations automatically. The computer designed by Prof. Howard was originally just an electronic mechanic. Then with the help of the IBM company, the electronics company that is now also a computer company in 1944, the design computer was resolved electronically. The computer was named “Harvard Mark I Automatic Sequence-Controlled Calculator (ASCC)”.
In 1948, began to find transistors, this is the forerunner of all electronic goods that have a small size drastically. No exception with a computer that previously had a super large size. In 1956 transistors began to be used on computers that made computers work faster, more economically, and smaller. Beginning with various large companies using computers as supporting financial information processing.
In 1958 Jack Kilby developed an integrated circuit (IC: integrated circuit). IC combines three electronic components in a small silicon disk made of quartz sand. The scientists then succeeded in inserting more components into a single chip called a semiconductor. The result is that computers are getting smaller, because some component functions have been taken over by the IC.
Computers are increasingly developing, and finally the name processor was invented in 1971. After that, computers became smaller and smaller, because many components were made together and their role was replaced by processors. After that, along with the development of the computer, found a LAN for the efficiency of sending data, sharing devices, or anything else. After developing a lot from year to year, now the computer has become what we see today.
