Question: Which electronic components are used in fourth generation computers?
The fourth generation of computers, which started in the 1970s and continues to the present day, is characterized by the use of microprocessors and very large scale integration (VLSI) circuits. A microprocessor is a single chip that contains the central processing unit (CPU) and other essential circuits, while VLSI refers to the technology of embedding thousands of transistors on a single microchip. These electronic components made the computers smaller, faster, cheaper, and more reliable than the previous generations.
The fourth generation of computers also introduced semiconductor memory devices, such as random access memory (RAM) and read-only memory (ROM), which replaced the magnetic core and drum memory used in the earlier generations. Semiconductor memory is faster, more compact, and more energy-efficient than magnetic memory. It also allows for non-volatile storage, which means that the data is not lost when the power is turned off.
The fourth generation of computers also witnessed the development of personal computers (PCs), which made computing accessible to individual users and small businesses. The first PC was developed by IBM in 1981, and it used an Intel 8088 microprocessor. Other examples of fourth generation computers are Apple Macintosh, Cray-1 supercomputer, and IBM notebooks.
The fourth generation of computers is still evolving with the advancement of microprocessor and VLSI technology, as well as artificial intelligence (AI) software. The current trend is to increase the processing power, memory capacity, and functionality of computers while reducing their size and cost.
