Historical development and generation of computers

Historical development and generation of computers from past to present are divided into 5 times of development or computer generation.What are the historical development let us refer to the explanation ofeach of his generation his development.

In essence the computer is calculating. Before terlahirnya the first computer used calculators and Abacus calculator is a mechanic, as like to faster in performing the calculations then make elekronik-based calculators namely computer.

So the history of the beginning of the creation of the computer is to speed up the calculations, however, do not assume that the first computer with the same Computer now, yg we gunaakan now is the result ofa long evolution from ancient discoveries. To know the history of his development read the explanation below.

The history of the development of the first Generation (1946-1959)

the first generation of computer

vacuum tube computers first generation

Since the onset of the second world war made the development of this first computer becomes faster because of the increased costs of funding for research or research. Development of ni aims to mengeksploitpotential of conveniently located, owned a computer so that it can be used to make the war strategy and steal information from the enemy.By that time the size of the computer is very spacious with large 7.45 feet x 50 feet and have a weight of around 35 tons. The result of this first research gained some computers include:

Colassus

Mark 1

ENIAC

EDVAC

UNIVACI

The hallmark of the first generation is

The use of vacuum tube (which makes the computer at the time of thevery large-sized)

The existence of magnetic cylinder for data storage.

Operating instructions created specifically for a specific task.

Each computer has a different binary code program called "machine language" (machine language) thing in the computer difficult to cause programmed and limit his speed.

The history of the development of the second generation Computers(1959 – 1964)

the second generation of the computer

the second generation of computer transistors

Stretch and LARC

The first machines utilizing new technology yg ni is a supercomputer. IBM supercomputer named Stretch, making and Sprery Rand makes a computer named LARC. Computer computer ni, which was developed for Atomic Energy Laboratory, can handle large amounts of data, a capability that is needed by the researchers of the atom. These machinesare very expensive and tend to be too complex for business computing needs, thus limiting its popularity. There are only two LARC yg neverinstalled and used: one at Lawrence Radiation Labs in Livermore, California, and others in the US Navy Research and Development Center in Washington D.C. the second generation Computers replace machine language depends on assembly language. Assembly language is the language using the shorthand abbreviation for replacing the binary code.

In the early 1960 's, the second generation of computers began to appear successful in the lucrative field of business, at the University, and in the Government. This is the second generation of computers computer yg full use of transistors. They also have components components that could

associated dngn computers on the present: a printer, disk storage, memory, operating system, and programs.

computer on the second generation:

The use of transistors so that its size is smaller.

The existence of magnetic core memory development help the development of the second generation computers are small, fast lebh, reliable, and energy efficient than his predecessors.

Replacement of machine language into the language of the Asembly.

Emerging programming language COBOL and FORTRAN.
