History Of Computer

Definition

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. heir ability of computers to follow a sequence of operations, called a program, make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers.

1.      Computer Generation 1

The history of the first generation was developed with characteristics that your computer is made with the purpose of performing specific jobs receive specific. Computer hard in the program and have a limited speed, the first computer using vacuum tubes with large quantities and lead to large-sized computer. To store data computer using magnetic cylinder. In addition to the size of a big, first-generation computers also use a great power.r.

2.      Computer Generation 2

In 1948, the invention of the transistor affect on the development of computers. With the invention of the transistor replaced the vacuum tube on the role of television, radio and computer. So that the size of the electronic device is reduced drastically.

In other findings in the form of magnetic core memory, helping the development of the second generation has a size smaller, faster, more energy efficient and more reliable.

In the second generation of computers will no longer use the machine language but replaced with assembly language. Assembly language is a language consisting of abbreviations to replace the binary code (the digits 0 and 1).

In the second generation fully using transistors. The components that can be associated with the computer at this time such as printers, data storage disks, memory, operating system and application programs.

3.      Computer Generation 3

In 1958, Jack Kilby an engineer with Texas Instruments developed the integrated circuit (Integrated Circuit / IC). IC combined three electronic components onto a small silicon disc made of quartz sand. Development of IC is made from quartz sand is able to handle problems in hot temperatures.

The scientists then managed to include more components into a single chip, called a semiconductor. The results of the discovery of these scientists make the size of computers become smaller as more components were squeezed onto a chip.

Other progress of third-generation computers is the use of the operating system or operating system. That allows the engine to work to run different programs at the same time with a central program that is tasked with monitoring and coordinating the computer's memory.

4.      Computer Generation 4

In the mid-1970s, computer assemblers to introduce their products to the general public. These computers are known as mini computers sold bundled with software that is easy to use by lay people.

In the history of its development, the computer continued evolution towards smaller sizes, from a computer that is on the table (desktop computers) into a computer which can be inserted into the bag (laptop), there is even a computer can (palmtops).

Along with the increased strength of a small computer, these computers can be connected together in a network to share a memory, software, information, and also to be able to communicate with each other.

5.      Computer Generation 5

Future plans fifth generation computer is a computer that already has the Artificial Intelligence (AI). So computers in the future may provide a response to the human desire. Fifth generation computers focused on AI (Artificial Intelligence / Artificial Intelligence), which is something related to the use of computers to carry out tasks which are analogous to human behavior.

INPUT DEVICE

Input device is a device used to receive input data and programs to be processed in a computer.

Serves as an input device for inputting data from the outside in a memory and processor to generate the necessary information.

Example for input device :

·         Keyboard

·         Mouse

·         Scanner, etc.

PROCESS DEVICE

The brain of a computer is on a processing unit (Process device). The processing unit is called CPU (Central Processing Unit). CPU function is as a processor and data processing can provide information that is required.

Process Equipment :

·         Processor

·         ROM (Read Only Mermory)

·         RAM (Random Access Memory), ect.

OUTPUT DEVICE

Output device is a tool that serves to release the results of processing or data processing from the CPU into a medium that can be read by humans or can be used for data storage rather than the outcome.

Example for output device :

·         Monitor

·         Printer

·         Spiker, etc.
