FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A second-generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation computer.

Detailed explanation-2: -The bipolar transistor was invented in 1947. From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the “second generation” of computers.

Detailed explanation-3: -In this generation, transistors were used that were cheaper, consumed less power, more compact in size, more reliable and faster than the first generation machines made of vacuum tubes. In this generation, magnetic cores were used as the primary memory and magnetic tape and magnetic disks as secondary storage devices.

Detailed explanation-4: -Examples of the second generation computers include IBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108. As a result, they worked on AC and therefore were faster than their predecessors. Having trouble with concepts like DBMS?

Detailed explanation-5: -The second generation of computers consists of two types of devices, transistors, and magnetic core. The transistors helped to develop a better computer than the first generation computers consisting of vacuum tubes. Some second generation of computers are IBM 1920, IBM 7094, CDC 1604, CDC 3600, IBM 1401, etc.
