In the beginning, only around ten to twenty components were contained by the integrated circuits technology, which was known as SSI (small scale integration). Later, it became possible to combine hundreds of components on a single chip with the development of advanced technology in the field of ICs, which was known as medium scale integration (MSI). With time, combining more than 30,000 components onto a single chip became possible. The effort is still continued for further advanced technology with the expectation that there will be developing technology that would integrate over millions of components on a single chip, which is called very-large-scale integration (VLSI).
The computers of the fourth generation contain LSI chip technology as their brain. The help of this technology made it possible to manufacture extremely powerful computers as well as very small in size. That led to a social revolution in the computer field. With the size of a postage stamp, on a single ship, an entire computer circuit was soon available. Later, it became possible to make a computer for everyone as the cost of manufacturing them became inexpensive.
|The size of fourth-generation computers decreased because of the high density of components.The development of these computers was intended for completely general-purpose use.They are more reliable, and the heat generation of these computers was negligible.The computers made in the fourth generation do not require air condition in many cases.These computers need minimum maintenance.The fourth-generation computers were inexpensive and portable as compared to previous versions.In terms of speed, computers of the fourth generation were much faster among all generations.During this period, PCs became more common as well as affordable.The objective of the development of these computers was for commercial production.In this generation of computers, all kinds of High-level languages can be used.||The manufacturing of VLSI (Very Large-Scale Integration) Chip was needed very advanced technology.One of the other limitations of these computers; they were highly sophisticated.They required a fan for cooling the system.Also, the manufacturing of Microprocessors needed high technical knowledge.The fabrication of ICs can be made by high quality and reliable system or technology.|
