Features of Second Generation Computers:
The second generation of computers marked a significant advancement in technology compared to the first generation. They were developed during the 1950s and 1960s and brought about several new features and improvements. However, one feature that was not present in second generation computers was the programming in mechanical language.
Features of Second Generation Computers:
1. Transistors were used: Second generation computers utilized transistors as the primary electronic component for processing and amplifying electrical signals. Transistors replaced the vacuum tubes used in first generation computers, resulting in smaller, faster, and more reliable machines.
2. Core memory was developed: Core memory, also known as magnetic core memory, was a significant development during the second generation. It provided a more efficient and reliable form of primary storage compared to the magnetic drums used in first generation computers.
3. Easier to program than first generation computers: Second generation computers introduced higher-level programming languages, such as FORTRAN and COBOL. These languages made programming easier and more accessible to a wider range of users.
4. Improved speed and performance: With the use of transistors and other technological advancements, second generation computers demonstrated significant improvements in speed and performance compared to their predecessors.
Not a feature of second generation computers:
- Programming in mechanical language: Mechanical language programming was not a feature of second generation computers. Mechanical language refers to programming systems that utilize mechanical components, such as gears and levers, to perform computations. This type of programming was primarily used in first generation computers and was subsequently phased out in favor of electronic programming languages in the second generation.
In summary, while second generation computers incorporated features such as the use of transistors, the development of core memory, and easier programming, they did not involve programming in mechanical language.
