The third generation of computer used integrated circuit rather than transistors or vacuum tubes The transition from vacuum tubes to solid-state components like transistors and ultimately integrated circuit (IC) chips marks the beginning of the history of computing hardware in the 1960s. Between 1953 and 1959, discrete transistors gained a reputation for being so dependable and cost-effective that they rendered future vacuum tube computers obsolete. In the mid-to-late 1960s, semiconductor memory was created using large-scale integration (LSI) technology based on metal-oxide semiconductors (MOS), and in the early 1970s, the microprocessor was created.

As a result, magnetic-core memory devices were replaced with solid-state static and dynamic semiconductor memories for primary computer memory, which significantly decreased the price, size, and power consumption of computers. In the 1970s, these developments led to the development of the tiny personal computer (PC), which was later followed by home and desktop computers, laptops, and finally mobile computers during the next several decades.

More about third generation of computer of computers

With the introduction of “Third generation of computer” computers to the commercial sector starting about 1966, the widespread expansion in computer use intensified. These mostly utilised early (integrated circuits with less than 1000 transistors) technology. The fourth generation, which is processor-based, follows the third generation of computer.

The creation of considerably more compact computers was made possible by the integrated circuit. In the 1960s and 1970s, the minicomputer was a key invention. More individuals now have access to computing power thanks to its more practical physical size as well as the expansion of the market for computer vendors. With their well-known PDP and VAX computer systems, Digital Equipment Corporation overtook IBM to become the second-largest computer manufacturer. The creation of significant new operating systems like Unix was also facilitated by smaller, more cheap equipment.

Fourth generation of computers 

The fourth generation’s roots are fundamentally different from the third generation of computer‘s, which were essentially scaled-down versions of mainframe computers. The fourth generation is based on the microprocessor, a computer processor that is housed on a single large-scale integration (LSI) MOS integrated circuit chip .In the beginning, microprocessor-based computers had extremely limited computing power and processing speed, and there was no attempt to make them smaller than minicomputers. They were speaking to a very other market. Since the 1970s, processing power and storage capacities have increased beyond all recognition, yet the fundamental technology of large-scale integration has remained mostly unchanged (LSI). The size of fourth generation was smaller than third generation of computer and when compared to all generation the size of current generation of computer is the smallest. The current generation of computer has made possible the construction of slim laptops

Current of computers

The current generation of computer is fifth generation of computers, it is the most advanced one in all generations. The current generation of computer is user friendly which means user does not need formal training to use the current generation of computer. The current generation of computer is smaller in size than the previous generation of computers. The Japan Ministry of International Trade and Industry (MITI) launched the current generation of computer. The current generation of computer uses ULSI technology. 

The current generation of computer uses AI technology which makes it the most advanced than other generations. The phrase “fifth generation” was used to suggest that the system was cutting-edge. The first generation of computers used vacuum tubes. The second generation used transistors and diodes. The third generation of computer used integrated circuits. The fourth generation used microprocessors. The current generation of computer are by far the most advanced generation in all of computer generations¬†
