The computer was invented a long time ago using the idea of ​​the abacus for calculation purposes. Until today, the computer is still developed to meet the desire of the new generation who wants the computer to have a simpler and faster function in processing information. The style and size of the computer is also important so that the customer is satisfied with the appearance and size of the computer. Since the Second World War, the computer has already been developing its technology, but the question arises from 1945. Von Neaumann is the manager who designed the discrete electronic variable automatic computer (EDVAC) in 1945, equipped with a memory which can also contain both a stored program. as data. The computer can be shut down at any time and then resumed using the stored memory technique as well as conditional control transfer and computer programming more versatile with this development. The key element of its architecture is the computer processing unit which makes it possible to coordinate all computer functions via a single source. In 1951, UNIVAC (Universal Automatic Computer) took advantage of this advance and predicted the winner of the 1952 American presidential election. This time is characteristic of the computer in that the instructions for use are made to order for a task specific. Every computer has a different binary-coded program, called machine language, that tells it how to operate. This computer is difficult to program and limits its versatility and speed. Other distinctive features were the use of vacuum tubes and magnetic drums for data storage. The invention of the transistor in 1948 replaced the large, cumbersome vacuum tube in televisions, radios and computers, but it was not until 1956 that the transistor was placed in the computer. So that's the size of a computer...... middle of paper......the Pentium 4 processor at 1.5 GHz. This processor continues to increase the value up to 2.2 GHz and so on. Instead of only focusing on the faster processor, they also improve the processor, like Intel released the first desktop computer with a dual core processor in 2005. The computer has also grown from a desktop computer to desk to a laptop. then now on tablet PC. Microsoft was the first to present this tablet PC. The computer industry also continues to develop the graphics system that allows the user to experience the image almost similar to reality. They are changing it from 2 dimensions (2D) to 3D and so far it has gone to 6D. The user can buy a user-friendly computer that comes in multiple sizes and has better features. The community can buy the computer because it is affordable today. Nowadays, the education system also uses technology in teaching as a teaching tool..
