IBM 1401 is a Second Generation Computer.
Explanation:
The classification of computers into different generations is based on the advancements in technology and the architectural changes that occurred over time. Each generation represents a significant improvement in terms of speed, size, and functionality.
First Generation Computers:
- The first generation computers were built using vacuum tubes and used punched cards for input and output.
- Examples of first generation computers include ENIAC, UNIVAC, and EDVAC.
Second Generation Computers:
- Second generation computers were developed in the late 1950s and early 1960s.
- They used transistors instead of vacuum tubes, which made them smaller, faster, and more reliable.
- These computers also introduced magnetic core memory and assembly language programming.
- Examples of second generation computers include IBM 1401, IBM 1620, and IBM 7090.
Third Generation Computers:
- Third generation computers were developed in the 1960s and 1970s.
- They used integrated circuits (ICs) instead of individual transistors, which further reduced the size and cost of computers.
- These computers also introduced high-level programming languages and operating systems.
- Examples of third generation computers include IBM System/360, DEC PDP-11, and CDC 6600.
Fourth Generation Computers:
- Fourth generation computers were developed in the 1970s and 1980s.
- They used microprocessors, which integrated thousands of transistors onto a single chip.
- This made computers even smaller, more powerful, and more affordable.
- These computers also introduced graphical user interfaces (GUI) and personal computers (PCs).
- Examples of fourth generation computers include IBM PC, Apple Macintosh, and Commodore 64.
In the given options, IBM 1401 falls under the second generation of computers because it was developed in the late 1950s and early 1960s and used transistors instead of vacuum tubes. It was a significant advancement over the first generation computers in terms of size, speed, and reliability.
