Today, computers are getting more sophisticated. But, before the computer is not as small, sophisticated, cool and light now. In the past, the size of the computer can spend a full space you know.
In its basic sense, computers are counting. Before the birth of the first computer the calculator used was an abacus and a mechanical calculator.
The term Computer comes from the Latin “computare”, which means the calculator, because initially the computer is more used as a tool in terms of counting the numbers before finally becoming a multifunctional device.
Computers today are the result of the long evolution of the ancient computers, which were originally mechanical and electronic devices. Here is an example of a computer invention.
Therefore want to be faster in doing the calculation, then make an electronic-based calculator that is computer.
The earliest history of computer creation was to speed up calculations. But do not assume that the first computer is the same now. The computers we use today are the result of the evolution of discovery since the first.
First Generation Computers
The first computer devices developed were computers for aircraft design and missiles. The scientist who initiated the concept of development is Konrad Zuse, an engineer from Germany. Later, in the mid-1940s, the computer went through a further development by John von Neuman.
The main feature of first generation computers is the CPU. Yes, the central processing unit contained in the first generation computer is the first machine used to operate the entire system in the computer. While the main program contained in the first generation of computers is “machine language”.
Second Generation Computers
An important discovery has taken place in this second generation. Is a transistor, a sophisticated tool that can maximize computer performance with a very small size. The discovery of this tool affects the development of computers in the second generation. In the 1960s, scientists tried to work on second generation computers.
Several intansi, companies, universities, and governments have taken advantage of the sophistication of second generation computers. The essence of second generation invention is the transistor, which makes the second generation of computers smaller than the first generation computers.
Third Generation Computers
In use, the transistor makes the computer heat faster. Thus, second generation computers began to be abandoned. Then a scientist named Jack Billy tried to do research. Then in 1958, he created a more sophisticated component than the transistor that made the computer heat up fast earlier. Ie IC or Integrated Circuit chip small that can accommodate many components into one.
That way, the size of the computer becomes smaller. Also, on third-generation computers is also faster in the operating system and able to run multiple programs simultaneously.
Fourth Generation Computers
In this generation, computers that use IC chips are then developed again. The Very Large Scale Integration Company tried to do the development in the 1980s. As a result, a single chip can accommodate thousands of components. From here, the term “personal computer” or PC appears. That is, computer devices began to be marketed to the individual sector. Do not stop there, there comes a computer device that is easy to carry everywhere, namely Laptops.
Fifth Generation Computer
The fifth generation computer is currently being done by various electronic vendors. Yes, fifth generation computers are often referred to as future generations of computers. Some small evidence is the emergence of smartphones, tablets, phablets, netbooks, ultrabooks, and more. The next development is a computer device that can be run without having to use physical contact (touch it), but using the brain.
