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 second-generation series of computers from IBM saw approximately six times higher computational speed than computers developed using vacuum tubes in the first generation. In particular, the IBM 7090 was built using over 50, 000 transistors, and extremely fast magnetic cores.

Detailed explanation-3: -2nd generation computers had transistors instead of vacuum tubes. 3. In 3th generation computers, ICs replaced transistors.

Detailed explanation-4: -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-5: -The second generation computers were used during 1957-1963. They are also known as transistor computers. The second generation of computers consists of two types of devices, transistors, and magnetic core.
