Latest Computers General Knowledge(GK) Questions and answers

1 .

Which of the following terms could be used to describe the concurrent processing of computer programs, via CRTs, on one computer system?

A)

Interactive processing

B)

Online processing

C)

Time-sharing

D)

All the above processing

Correct Answer : All the above processing

Interactive processing is the simplest way to work on a system. You log in, run commands which execute immediately, and log off when you've finished. You can use either the command line or a graphical environment. Interactive jobs run directly on the limited number of login nodes (servers) on each cluster.

2 .

When the time to establish link is large and the size of data is small, the preferred mode of data transfer is

A)

Packet switching

B)

Circuit switching

C)

Time division multiplexing

D)

None of the above

Correct Answer : Packet switching

3 .

Which of the following bus types are used by the Apple Macintosh computer?

A)

MCA

B)

EISA

C)

NuBus

D)

PCI Bus

Correct Answer : NuBus

NuBus is a 32-bit parallel computer bus, originally developed at MIT and standardized in 1987 as a part of the NuMachine workstation project. The first complete implementation of the NuBus was done by Western Digital for their NuMachine, and for the Lisp Machines Inc.

4 .

What is meant by computer literacy?

A)

Ability to assemble computers

B)

Ability to write computer programs

C)

Knowing computer related vocabulary

D)

Knowing what a computer can and cannot do

Correct Answer : Knowing what a computer can and cannot do

The knowledge and ability to use computers efficiently. Computer literacy can also refer to the comfort level someone has with using computer programs and other applications that are associated with computers. Another valuable component of computer literacy is knowing how computers work and operate.

5 .

Which of the following is used to check for errors in RAM chips?

A)

Parity chip

B)

ROM chip

C)

EPROM chip

D)

Microprocessor chip

Correct Answer : Parity chip

The parity chip is used for error checking, to make sure that the other chips aren't making any errors.

6 .

The computers that we use are digital whereas we live in an analog world which means that we have to translate analog data into digital data. What is the name of the circuit which helps us in this conversion?

A)

D/A converter

B)

A/D converter

C)

Adapter

D)

Voice recognition

Correct Answer : A/D converter

An analog-to-digital converter, or ADC as it is more commonly called, is a device that converts analog signals into digital signals. Analog information is transmitted by modulating a continuous transmission signal by amplifying a signal's strength or varying its frequency to add or take away data.

7 .

When used with I/O devices, the term intelligent implies

A)

a color output capability

B)

speech processing capability

C)

high speed printing capability

D)

feature to support offline and online tasks

Correct Answer : feature to support offline and online tasks

8 .

The binary equivalent of the Hexadecimal number 7BD is

A)

11110111101

B)

101110111101

C)

111010111101

D)

None of the above

Correct Answer : 11110111101

7bd from hexadecimal to binary is 11110111101.

9 .

Which was the first computer to use transistors instead of vacuum tubes?

A)

Burroughs E-101

B)

Intel-650

C)

IBM-1401

D)

Datamatic-1000

Correct Answer : IBM-1401

IBM- 1401 was the first computer to use transistor instead of vacuum tubes.

A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky, and were unreliable. A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation machines.

Because the transistor was so much smaller and consumed significantly less power, a computer system built with transistors was also much smaller, faster, and more efficient than a computer system built with vacuum tubes.

10 .

The punched card used in the IBM System/3 contains

A)

80 columns

B)

96 columns

C)

120 columns

D)

126 columns

Correct Answer : 96 columns

In the late 1960s, IBM introduced a new, smaller, round-hole, 96-column card format along with the IBM System/3 computer. These cards have tiny (1 mm), circular holes, smaller than those in paper tape. Data is stored in 6-bit BCD, with three rows of 32 characters each, or 8-bit EBCDIC.
