152.176.153.177. Answers:154.178.155.179.156.180. 1. Which generation of computer is still under development157.181.

Correct Answer: b. Fifth Generation

Explanation: Todays computer fall under the fourth generation computers thatuses the LSI and VLSI Integrated Circuits. For fifth generation computers it isexpected for Ultra Large Scale Integrated Circuits (ULSI). The study for usingGallium Arsenide instead of silicon chips is underway. Electrons can travel 5times faster in Gallium Arsenide compared to the silicon. Similarly, geneticallyengineered protein molecules are being tried for processors. Fifth generationcomputers are expected to have artificial intelligence, ability to use naturallanguage.

158.182.2. Artificial Intelligence is associated with which generation?159.183. Correct Answer: c. Fifth GenerationExplanation: A computer is a slave in a box. This is a saying due to the lack ofintelligence in computer in spite of their speed, accuracy, diligence and reliability.A computer can only perform instructed task in the way already programmed.Thus, scientists are trying to develop artificial intelligence in computers so thatthey can think and make decisions themselves. This is expected for fifthgeneration computers.

184.3. Which operation is not performed by computer

185. Correct Answer: d. UnderstandingExplanation: Computers cant understand since they dont have intelligence. Letshope in fifth generation they will achieve artificial intelligence and be able tounderstand.

186.4. Fifth generation computer is also known as

187. Correct Answer: a. Knowledge information processing systemExplanation: Fifth Generation computers will have artificial intelligence and willbe able to understand making knowledge information processing system possible,

188.5. Central Processing Unit is combination of

189. Correct Answer: d. Arithmetic logic and control unitExplanation: Arithmetic logic and control unit along with memory unit forms acomplete central processing unit and central processing unit along withinput/output unit forms a computer system.


65/151

190.6. The brain of any computer system is

191. Correct Answer: c. Central Processing UnitExplanation: Control unit or arithmetic logical unit alone can not represent the

function of brain to compare with neither does storage unit only. CentralProcessing Unit is the combination of control, arithmetic logic and memory unitsthus can be compared with brain that controls the body, processes its functionsand remembers.

192.7. Pick the one that is used for logical operations or comparisons such as less than equalto or greater than.

193. Correct Answer: a. Arithmetic and Logic UnitExplanation: Logical sub-unit of ALU performs all the comparisons such as lessthan equal to or greater than. Arithmetic sub-unit of ALU performs calculations

such as addition, subtraction and so on.194.8. Analog computer works on the supply of

195. Correct Answer: a. Continuous electrical pulsesExplanation: Analog computers works on the continuous electrical pulses anddigital computers work on the discrete electrical pulses. Analog computers needto process physical quantities such as temperature, pressure, speed etc.

196.9. Digital devices are

197. Correct Answer: a. Digital Clock.Explanation: Automobile speed meter and clock with a dial and two hands areanalog devices. Speed meter works on speed of wheel and the later works ontension of dialed spring.

198.10. The computer that process both analog and digital is called

199. Correct Answer c. Hybrid ComputerExplanation: Analog, Digital and Hybrid are the three classes of computers basedon the work or principle on which computer work. Hybrid computers can performboth the tasks of analog computers as well as hybrid computers. These computersare used in aircraft, hospitals where measuring physical quantities and convertingthem into digital data to analyze is required.
