American Standard Code for Information InterchangeExplanation: ASCII is a code which converts characters – letters, digits, punctuationsand control characters such as Alt, Tab etc – into numeral form. ASCII code is used torepresent data internally in micro-computers. ASCII codes are 7 bits and can represent0 to 127 and extended ASCII are 8 bits that represents 0 to 255.4. Which of the following is first generation of computerCorrect Answer: a. EDSACExplanation: IBM-1401, CDC-1604 is second generation computer. ICL-2900 is a fourthgeneration computer. EDSAC is important in the development of computer since it wasthe first computer to use John von. Neumann’s Stored Program Concept. It used 3000vacuum tubes and computers with vacuum tubes are of first generation computers.5. Chief component of first generation computer wasCorrect Answer: b. Vacuum Tubes and ValvesExplanation: Transistors were used for second generation computers and integratedcircuits in third generation. First generation computers used vacuum tubes and valvesas their main electronic component. Vacuum Tubes were invented by Lee DeForest in1908.
  45. 45. 6. FORTRAN isCorrect Answer: c. Formula TranslationExplanation: FORTRAN (Formula Translation) is one of the earlier High Levelprogramming languages used to write scientific applications. It was developed by IBMin 1956.7. EEPROM stand forCorrect Answer: a. Electrically Erasable Programmable Read Only MemoryExplanation: There are three types of ROM namely, PROM, EPROM and EEPROM.PROM can’t be reprogrammed, EPROM can be erased by exposing it in high intensityultraviolet light and EEPROM can be erased and reprogrammed electrically. It is notneeded to be removed from the computer to be modified.8. Second Generation computers were developed duringCorrect Answer: 1956 to 1965Explanation: Second generation computers used transistors as their main electroniccomponent. Transistor was invented by Bell Lab Scientists John Burdeen, WalterBrattain and William Shockley in 1947 and won the Nobel Prize in 1956 but it was notused in computers till 1956. The second generation continued until the implementationof IC chips invented by Jack Kilby in Texas Instruments in 1958.9. The computer size was very large inCorrect Answer: a. First GenerationExplanation: It is obvious that computers developed with more power, reliability, speedand smaller sizes due to the enhancement of technology. First generation computersused 1000s of vacuum tubes that required lot of space made them gigantic in size. Singletransistor could replace 1000 vacuum tubes and a single IC chip replaced 1000s oftransistors made computers smaller and more speedy.10. Microprocessors as switching devices are for which generation computersCorrect Answer: Fourth GenerationExplanation: Microprocessors further revolutionized the development of computers.Personal microcomputers were possible due to the microprocessors. The firstmicroprocessor called Intel 4004 was developed by American Intel Corporation in 1971.Microprocessors are used in the computers of fourth generation computers._______________________________________________

Fifth GenerationExplanation: Today’s computer fall under the fourth generation computers that usesthe LSI and VLSI Integrated Circuits. For fifth generation computers it is expected forUltra Large Scale Integrated Circuits (ULSI). The study for using Gallium Arsenideinstead of silicon chips is underway. Electrons can travel 5 times faster in GalliumArsenide compared to the silicon. Similarly, genetically engineered protein moleculesare being tried for processors. Fifth generation computers are expected to have artificialintelligence, ability to use natural language.2. Artificial Intelligence is associated with which generation?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. Acomputer can only perform instructed task in the way already programmed. Thus,scientists are trying to develop artificial intelligence in computers so that they can think
  48. 48. and make decisions themselves. This is expected for fifth generation computers.3. Which operation is not performed by computerCorrect Answer: d. UnderstandingExplanation: Computers can’t understand since they don’t have intelligence. Let’s hopein fifth generation they will achieve artificial intelligence and be able to understand.4. Fifth generation computer is also known asCorrect Answer: a. Knowledge information processing systemExplanation: Fifth Generation computers will have artificial intelligence and will be ableto understand making knowledge information processing system possible,5. Central Processing Unit is combination ofCorrect 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 with input/outputunit forms a computer system.6. The brain of any computer system isCorrect Answer: c. Central Processing UnitExplanation: Control unit or arithmetic logical unit alone can not represent the functionof brain to compare with neither does storage unit only. Central Processing Unit is thecombination of control, arithmetic logic and memory units thus can be compared withbrain that controls the body, processes its functions and remembers.7. Pick the one that is used for logical operations or comparisons such as less than equal to orgreater than.Correct Answer: a.
