Computer Knowledge Questions on Introduction to Computers | Set – 44

Correct Answer: A. Electronic machine

Explanation- A computer is a electronic machine or device that performs processes, calculations and operations based on instructions provided by a software or hardware program. It has the ability to accept raw data as input, processes it and produce information as output.

Correct Answer – C. Data

Explanation- A computer is an electronic machine which stores, reads and processes data to produce meaningful information.

Correct Answer – D. Microprocessors

Explanation-

Correct Answer – D. All of the Above

Explanation- The characteristics of the computer system are as follows −

Speed- A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. Computers can process millions (1,000,000) of instructions per second. The time taken by computers for their operations is microseconds and nanoseconds.

Accuracy- Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.

Diligence- A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings.

Versatility- Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency.

Reliability- A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.

Automation- Computer performs all the tasks automatically i.e. it performs tasks without manual intervention.

Memory- A computer has built-in memory called primary memory where it stores data. Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data.

Correct Answer – B. Assembly Language

Explanation-

Correct Answer: A. Electronic Delay Storage Automatic Calculator

Explanation-EDSAC is first generation of computer. EDSAC. The Electronic Delay Storage Automatic Calculator (EDSAC), developed at Britain’s Cambridge University, ran its first programs in 1949. It became the first stored-program computer in regular use, heralding the transition from test to tool.

Correct Answer – A. Scale

Explanation- Ultra large-scale integration (ULSI) is the process of integrating or embedding millions of transistors on a single silicon semiconductor microchip. ULSI technology was conceived during the late 1980s when superior computer processor microchips, specifically for the Intel 8086 series, were under development. ULSI is a successor to large-scale integration (LSI) and very large-scale integration (VLSI) technologies but is in the same category as VLSI.

Correct Answer – C. Transistors

Explanation-An Integrated Circuit (IC) is a minuscule electronic circuit that consists of active and passive components as well as interconnections. These components include transistors, diodes, capacitors and resistors.

Correct Answer – A. Charles Babbage

Explanation-

• Father of Computers – Charles Babbage
• Father of Modern Computers – Alan Turing
• One of the inventors of Microprocessor – Ted Hoff

Correct Answer: D. Micro Computers

Explanation- Microcomputers are also known as Personal Computers and these include Desktop Computers, Laptops, Notebooks, Mini Tower Microcomputers and Full Tower Microcomputers.
