THE COMPUTER

HISTORY 

The man faced with the need to create a machine that does the repetitive and arduous tasks, created different equipment, such as pascal with his calculator that worked with gears. It is said that the first tool was the Abacus, but we had the Quipu. In the United States Census began the revolution of the machines created the first machine that worked with perforated cards, then they created machines that were the size of a large room that to do any mathematical calculation it was necessary a group of engineers to make the changes Respective then the new advances appear and the computers begin to evolve talking about them as the first generation, second, third, fourth, fifth generation is where we are now. When we talk about 286,486,586, pentium I, pentium II, pentium III, pentium IV, and the current demonized CORE refers to the evolution of the microprocessor.

CLASSIFICATION

SUPERCOMPUTER

A supercomputer is the most powerful computer available at any given time. These machines are built to process huge amounts of information very quickly. Supercomputers can cost from $ 10 million to $ 30 million, and consume enough power to power 100 homes.

MACROCOMPUTERS

The largest computer in common use is the macrocomputer. The mainframe is designed to handle large amounts of input, output and storage.

MINICOMPUTERS

The best way to explain the capabilities of a minicomputer is by saying that they are somewhere between those of a macrocomputer or mainframe and those of personal computers. Like macrocomputers, minicomputers can handle a much larger number of inputs and outputs than a personal computer. Although some minis are designed for a single user, many can handle dozens or even hundreds of terminals.

WORK STATIONS

Among minicomputers and microcomputers (in terms of processing power) there is a class of computers known as workstations. A workstation looks like a personal computer and is usually used by one person, just like a computer. Although the workstations are more powerful than the average personal computer. The workstations have a big difference with their premiums microcomputers in two main areas. Internally, workstations are built differently than microcomputers. They are generally based on another CPU design philosophy called a computation processor with a reduced set of instructions (RISC), which results in faster processing of instructions.

PERSONAL COMPUTERS

Small computers commonly found in offices, classrooms, and homes. Personal computers come in all shapes and sizes. Desktop Models The most common personal computer style is also the one that was introduced first: the desktop model. Notebook computers Notebook computers, as the name implies, approximate the form of an agenda. Laptops are the predecessors of notebook computers and are slightly larger than these. Digital Personal Assistants Digital personal assistants (PDAs) are the smallest laptops. PDAs, also sometimes called palmtops, are much less powerful than notebook and desktop models. They are generally used for special applications, such as creating small spreadsheets, displaying important phone numbers and addresses, or keeping track of dates and schedules. Many can connect to larger computers to exchange data.
