The second era (Second Generation Computer) 2502 (1959)-2506 (1963)Transistor is used on the computer, making it a smaller and more efficient to work with speed and more precise. In addition In this era, there was also the idea to use with your computer, such as the language format instead (FORTRAN), thus making it easier to write programs for use with the machine.The identity of the computer era 2Using a transistor (Transistor) which was built from semiconductor devices instead of (Semi-Conductor) vacuum tube, because only one transistor. Has the performance equivalent of hundreds evacuated tube tube? In this era of computers makes it smaller. Using less energy Low heat to work faster and get even more reliability.Collect data by using the memory ring magnet (Magnetic Core)Processing speed in one direction approximately one in a thousand of a second (mS: Millisecond)Order more convenient because it works with Chinese symbols (Assembly Language)High-level language development starts (High Level Language) in this era.Third generation (the Third Generation Computer) 2507 (1964)-2512 (1969)Computers in this era started after only 5 years of transistor usage because the ingenuity point about integrated circuit (Integrated-Circuit) or known as yo "ICS" (IC), which is the ICS allows various circuit components and can be placed on the plates, chips (chip) is a small single sheet-pama replacement transistor do to save a lot of space.They also began using database management systems (DBMS: Data Base Management Systems) and the development of computers to work together as many. In the same time and have a system that users can interact with several people at the same time (Time Sharing)The identity of the computer age 3Using integrated circuit (IC: Integrated Circuit), or an integrated circuit c and large scale (Large Scale Integration: LSI) is a device.Processor speed in one direction for about one million of the second. (Microsecond: mS) (higher than 1 in the era of computers, about 1000 times)Working with the General high level languages.The fourth generation (Fourth Generation Computer) 2513 (1970)-2532 (1989)As the era of the semiconductor integrated circuit's building capacity is very high (Very Large Scale Integrated: VLSI), which can minimize many common ICS circuit into the same circuit with the invention. Microprocessor (Microprocessor), a small, cheap, and has the ability to run fast and high. So there is a personal computer (Personal Computer) considered in this era.The identity of the computer era 4Large scale integrated circuit devices (Large Scale Integration: LSI) and very large scale integrated circuit (Very Large Scale Integration: VLSI) devices.With the speed at which each processing command, about one billion seconds. (Nanosecond: nS) and subsequent development until the speed in processing each of the commands. About one in a trillion of seconds (Picosecond: pS)The fifth era (Fifth Generation Computer) 2533 (1990) till now.In this era, focusing on the development The ability of a computer system and comfort in using computers is clearly. Has developed a new computer, small portable (Portable Computer), up available in this era.Development of VLSI devices, easy to use and has a higher capacity, including research and development projects about artificial intelligence (Artificial Intelligence: AI) is at the heart of the development of computer systems in this era. With the hope that a computer system can analyze problems with reason.Elements of artificial intelligence systems consist of 4 topics:1. the system of the robot or robots (Robotics or Robotarm System)Is the human body model robots to work with computers. Is intended to make it work instead of humans in tasks that require speed or hazardous, such as industrial robots or robot bombs etc.2. when processing spoken language systems (Natural Language Processing System)Is the development of a computer system to be able to synthesize sounds that exist in nature (Synthesize) to communication with humans, such as calculator, say (Talking Calculator) or alarm clock talking (Talking Clock), etc.3. speech recognition (Speech Recognition System)Is the development of human language understanding, computer systems, and can recognize human speech continued. That is, it allows the computer to work with the spoken language, such as job security, a publication for persons with disabilities, etc.4. expert systems (Expert System)Is there a computer system developed to meet knowledge reasoning for diagnosing problems using the knowledge or experience in solving other problems, there is a reason. This system requires a database (Database), a man who has the body of knowledge in a database so that a computer system can analyze the problems derived from the knowledge base, such as a computer or a computer disease analysis predicts destiny, etc.
