Which one of the following is the first second-generation computer?
Which one of the following is the first second-generation computer?
The correct option is A IBM 7090
IBM 7090 is the first second-generation computer
The first generation of electronic computers used vacuum
tubes, which generated large amounts of heat, were bulky, and were unreliable.
A second generation of computers, through the late 1950s and 1960s featured
circuit boards filled with individual transistors and magnetic core memory.
The IBM 7090 is a second-generation transistorized
version of the earlier IBM 709 vacuum tube mainframe computers that was
designed for "large-scale scientific and technological applications".
The 7090 is the third member of the IBM 700/7000 series scientific computers.
The first 7090 installation was in November 1959.
The 7090 uses a 36-bit word length, with an address space
of 32,768 words (15-bit addresses). It operates with a basic memory cycle of
2.18 μs, using the IBM 7302 Core Storage core memory technology from the IBM
7030 (Stretch) project.
