Detailed explanation-1: -The first generation computers used vacuum tubes for circuitry and magnetic drums for memory and were often enormous, taking up entire rooms. First Generation: Vacuum Tubes (1940-1956): The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.
Detailed explanation-2: -One of the earliest functioning computers to employ drum memory was the Atanasoff–Berry computer (1942).
Detailed explanation-3: -The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit).
Detailed explanation-4: -second generation of computers. Machines whose designs were started after 1955 (approximately) and are characterized by both vacuum tube (valve) and discrete transistor logic. They used magnetic core main memory.
Detailed explanation-5: -A magnetic drum is a magnetic storage device used in many early computers as the main working memory, similar to how modern computers use random access memory (RAM) cards. In some cases, magnetic drum memory was also used for secondary storage.
