The correct answer is: E. None of the above
The IBM 7000 series was a family of mainframe computers introduced by IBM in 1964. It was the successor to the IBM 7090 series and was the first computer series to use transistor technology. The IBM 7000 series was used for a variety of applications, including scientific computing, business applications, and data processing.
The IBM 7000 series was a modular computer, which means that it was made up of individual modules that could be plugged together to create a system with the desired configuration. This modular design made the IBM 7000 series easy to maintain and upgrade.
The IBM 7000 series was also a transistorized computer, which means that it used transistors instead of vacuum tubes. Transistors are smaller and faster than vacuum tubes, which made the IBM 7000 series more powerful and efficient than previous computer systems.
The IBM 7000 series was a successful computer series and was used by many businesses and organizations. It was eventually replaced by the IBM 360 series, which was introduced in 1964.
Here is a brief explanation of each option:
- Option A: The IBM 7000 series was a third-generation computer, not a second-generation computer. Second-generation computers used vacuum tubes, while third-generation computers used transistors.
- Option B: The IBM 7000 series did not use VLSI. VLSI is a type of integrated circuit that was not developed until the 1970s.
- Option C: The IBM 7000 series did not employ semiconductor memory. Semiconductor memory is a type of memory that uses transistors, while the IBM 7000 series used magnetic core memory.
- Option D: The IBM 7000 series did have modular construction. However, this was not a unique feature of the IBM 7000 series. Many computer systems of the time were modular.
