The answer to the given question is explained in the explanation.
Explanation:
1940 - 1956: First Generation - It used Vacuum Tube
These early computers used vacuum tubes for electrical circuits and magnetic drums for memory. As a result, they are huge, literally taking up entire rooms and costing a fortune to manage. These are inefficient materials that generate a lot of heat, draw a lot of electricity, and then generate a lot of heat, causing continued failure.
These first-generation computers were based on "machine language" (which is the most basic programming language a computer can understand). These computers are limited to solving one problem at a time. Entry is based on punch cards and paper strips. The output appears on the printout. Two notable machines from this era were the UNIVAC and the ENIAC - UNIVAC was the first commercial computer purchased in 1951 by one company - the US Census Bureau.
1956 - 1963: Second Generation - Transistor
The replacement of vacuum tubes with transistors saw the introduction of the second generation of computers. Although first invented in 1947, the transistor did not see much use in computers until the late 1950s. They are a big improvement over vacuum tubes, although they still expose the computer to damaging heat levels. However, they are far superior to vacuum tubes, making computers smaller, faster, cheaper, and less power-hungry. They still rely on punched cards for input/print.
Language has evolved from a confusing binary language to a symbolic language ("assembly language"). This means that programmers can create instructions in words
Around the same time, high-level programming languages were developed (early versions of COBOL and FORTRAN). Semiconductors were the first computers to store instructions in their memory - moving from magnetic drums to magnetic core "technology". The first versions of these machines were developed for the atomic energy industry.
1964 - 1971: Third Generation - Integrated Circuits were used in the Third generation
During this period, transistors have now been miniaturized and placed on silicon chips (known as semiconductors). This resulted in a significant increase in the speed and efficiency of these machines. These were the first computers where the user interacted with a keyboard and screen that communicated with the operating system, a significant leap forward from punch cards and printouts. This allows these machines to run multiple applications at the same time using a central program that works to monitor memory.
As a result of these advances making machines cheaper and smaller, a new mass consumer market emerged in the 1960s. This revolution can be summed up in one word: Intel. This chip manufacturer developed the Intel 4004 chip in 1971, which placed all computer components (processor, memory, input/output controls) on a single chip. What filled a room in the 1940s now fits in the palm of your hand. Intel chips contain thousands of integrated circuits. 1981 saw the first computer (IBM) designed specifically for home use, and 1984 saw the MacIntosh being introduced by Apple. Microprocessors have even gone beyond computers and become an increasing number of everyday products.
The growing power of these small computers makes it possible to link them together, thus creating a network
