Fourth Generation of Computer

The fourth generation of computers spanned the period between 1971 and 1981, and it is marked by the introduction of microprocessors, which made computers even smaller, more powerful, and more affordable.

Microprocessors are complete CPUs (central processing units) on a single chip. This made it possible to create small, powerful computers that were more affordable than earlier computers. The first commercially available microprocessor was the Intel 4004, released in 1971.

During the fourth generation of computers, personal computers (PCs) were introduced, starting with the Altair 8800 in 1975. These early PCs were sold as kits and required assembly, but they opened up the world of computing to a much wider audience.

In addition to the development of microprocessors and personal computers, other significant developments during this era include the introduction of floppy disks for data storage, the development of the BASIC programming language, and the creation of Ethernet, which laid the foundation for computer networking.

The fourth generation of computers also saw the development of graphical user interfaces (GUIs), which made it easier for users to interact with computers. The first commercially successful computer with a GUI was the Apple Lisa, released in 1983.

Overall, the fourth generation of computers marked a major turning point in the history of computing, as it made computers more affordable and accessible to the general public. The development of microprocessors and personal computers laid the foundation for the explosive growth of the computer industry in the years that followed.
