But their size and cost limited their accessibility to only a select few.

However, everything was about to change with the emergence of microprocessors. These tiny yet powerful chips revolutionized the computing landscape, bringing the power of mainframe computers within the reach of everyday users.

One key player in this transition was IBM. The American technology company played a pivotal role in the development and popularization of both mainframe computers and microprocessors. IBM’s mainframe computers dominated the market, providing unparalleled computing power for industries like finance, healthcare, and government.

“IBM introduced the System/360 in 1964, a family of compatible mainframe computers that set the industry standard. These machines were capable of handling tremendous volumes of data, making them invaluable tools for businesses and organizations.”

However, as technology advanced, the limitations of the mainframe became apparent. The need for more compact and affordable computing solutions paved the way for microprocessors.

Microprocessors, developed by companies such as Intel and Motorola, combined the essential components of a computer (central processing unit, memory, and input/output circuits) onto a single chip. This technological breakthrough allowed for the creation of smaller, more affordable, and portable computers.

With the birth of personal computers, individuals could now enjoy the benefits of computing power right at their fingertips. The advent of microprocessors brought about a democratization of technology, transforming computing from a luxury reserved for large organizations to an indispensable tool for people from all walks of life.

The Impact of Microprocessors

Microprocessors revolutionized the world of computing in several ways. Here are some key highlights:
