1. EBCDIC stands for Correct Answer: a. Extended Binary Coded Decimal Interchange Code Explanation: EBCDIC is an 8-bit binary code for larger IBMs primarily mainframes in which each byte represent one alphanumeric character or two decimal digits. 256 characters can be coded using EBCDIC.

2. BCD is Correct Answer: a. Binary Coded Decimal Explanation: BCD is a binary coded notation in which each of the decimal digits is expressed as a 8-bit binary numeral. For example in binary coded decimal notation 12 is 0001 0010 as opposed to 1100 in pure binary.

3. ASCII stands for Correct Answer: c. American Standard Code for Information Interchange Explanation: ASCII is a code which converts characters – letters, digits, punctuations and control characters such as Alt, Tab etc – into numeral form. ASCII code is used to represent data internally in micro-computers. ASCII codes are 7 bits and can represent 0 to 127 and extended ASCII are 8 bits that represents 0 to 255.

4. Which of the following is first generation of computer Correct Answer: a. EDSAC Explanation: IBM-1401, CDC-1604 is second generation computer. ICL-2900 is a fourth generation computer. EDSAC is important in the development of computer since it was the first computer to use John von. Neumann’s Stored Program Concept. It used 3000 vacuum tubes and computers with vacuum tubes are of first generation computers.

5. Chief component of first generation computer was Correct Answer: b. Vacuum Tubes and Valves Explanation: Transistors were used for second generation computers and integrated circuits in third generation. First generation computers used vacuum tubes and valves as their main electronic component. Vacuum Tubes were invented by Lee DeForest in 1908.

6. FORTRAN is Correct Answer: c. Formula Translation Explanation: FORTRAN (Formula Translation) is one of the earlier High Level programming languages used to write scientific applications. It was developed by IBM in 1956.

7. EEPROM stand for Correct Answer: a. Electrically Erasable Programmable Read Only Memory Explanation: 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 intensity ultraviolet light and EEPROM can be erased and reprogrammed electrically. It is not needed to be removed from the computer to be modified.

8. Second Generation computers were developed during Correct Answer: 1956 to 1965 Explanation: Second generation computers used transistors as their main electronic component. Transistor was invented by Bell Lab Scientists John Burdeen, Walter Brattain and William Shockley in 1947 and won the Nobel Prize in 1956 but it was not used in computers till 1956. The second generation continued until the implementation of IC chips invented by Jack Kilby in Texas Instruments in 1958.

9. The computer size was very large in Correct Answer: a. First Generation Explanation: It is obvious that computers developed with more power, reliability, speed and smaller sizes due to the enhancement of technology. First generation computers used 1000s of vacuum tubes that required lot of space made them gigantic in size. Single transistor could replace 1000 vacuum tubes and a single IC chip replaced 1000s of transistors made computers smaller and more speedy.

10. Microprocessors as switching devices are for which generation computers Correct Answer: Fourth Generation Explanation: Microprocessors further revolutionized the development of computers. Personal microcomputers were possible due to the microprocessors. The first microprocessor called Intel 4004 was developed by American Intel Corporation in 1971. Microprocessors are used in the computers of fourth generation computers.

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.

2. Artificial Intelligence is associated with which generation? Correct Answer: c. Fifth Generation Explanation: ‘A computer is a slave in a box’. This is a saying due to the lack of intelligence 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 that they can think and make decisions themselves. This is expected for fifth generation computers.

3. Which operation is not performed by computer Correct Answer: d. Understanding Explanation: Computers can’t understand since they don’t have intelligence. Let’s hope in fifth generation they will achieve artificial intelligence and be able to understand.

4. Fifth generation computer is also known as Correct Answer: a. Knowledge information processing system Explanation: Fifth Generation computers will have artificial intelligence and will be able to understand making knowledge information processing system possible,

5. Central Processing Unit is combination of Correct Answer: d. Arithmetic logic and control unit Explanation: Arithmetic logic and control unit along with memory unit forms a complete central processing unit and central processing unit along with input/output unit forms a computer system.

6. The brain of any computer system is Correct Answer: c. Central Processing Unit Explanation: Control unit or arithmetic logical unit alone can not represent the function of brain to compare with neither does storage unit only. Central Processing Unit is the combination of control, arithmetic logic and memory units thus can be compared with brain 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 or greater than. Correct Answer: a. Arithmetic and Logic Unit Explanation: Logical sub-unit of ALU performs all the comparisons such as less than equal to or greater than. Arithmetic sub-unit of ALU performs calculations such as addition, subtraction and so on.

8. Analog computer works on the supply of Correct Answer: a. Continuous electrical pulses Explanation: Analog computers works on the continuous electrical pulses and digital computers work on the discrete electrical pulses. Analog computers need to process physical quantities such as temperature, pressure, speed etc.

9. Digital devices are Correct Answer: a. Digital Clock. Explanation: Automobile speed meter and clock with a dial and two hands are analog devices. Speed meter works on speed of wheel and the later works on tension of dialed spring.

10. The computer that process both analog and digital is called Correct Answer c. Hybrid Computer Explanation: Analog, Digital and Hybrid are the three classes of computers based on the work or principle on which computer work. Hybrid computers can perform both the tasks of analog computers as well as hybrid computers.
