Answers:
1. Which generation of computer is still under development
Correct Answer: b. Fifth Generation
Explanation: Today’s computer fall under the fourth generation computers that uses the LSI and VLSI Integrated Circuits. For fifth generation computers it is expected for Ultra Large Scale Integrated Circuits (ULSI). The study for using Gallium Arsenide instead of silicon chips is underway. Electrons can travel 5 times faster in Gallium Arsenide compared to the silicon. Similarly, genetically engineered protein molecules are being tried for processors. Fifth generation computers are expected to have artificial intelligence, ability to use natural language.
