Computer and Information Technology-part (1)

Total Questions: 50

1. The first Computer was made by : [U.P.P.C.S.(pre) 2007]

Correct Answer: (c) Charles babbage
Solution:Charles Babbage was considered to be the father of computing after his invention and concept of the Analytical Engine in 1837. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control and integrated memory. It was hailed as the first general purpose computer concept. Unfortunately because of funding issues, this computer was never built while he was alive.

2. Who is known as Father of Computer? [U.P. Lower Sub. (Mains) 2013]

Correct Answer: (d) Charles Babbage
Solution:Charles Babbage was considered to be the father of computing after his invention and concept of the Analytical Engine in 1837. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control and integrated memory. It was hailed as the first general purpose computer concept. Unfortunately because of funding issues, this computer was never built while he was alive.

3. Who invented electronic computer? [M.P.P.C.S.(PRE) 2006 M.P.P.C.S.(PRE) 2000]

Correct Answer: (a) DR. Alan M. Turing
Solution:Colossus was the name of a series of electronic digital computer developed for British code breakers in 1943-1945 to help in the cryptanalysis of the Lorenz Cipher. It was designed by the British engineer Tommy Flowers. Alan Mathison Turing also contributed to its design but the fact was that he was not directly involved in it. But in the available options, Dr. Alan M. Turing is the correct answer.

4. The digital computer was developed in : [Uttarakhand P.C.S. (pre) 2002]

Correct Answer: (b) Britain
Solution:Colossus was the name of a series of electronic digital computer developed for British code breakers in 1943-1945 to help in the cryptanalysis of the Lorenz Cipher. It was designed by the British engineer Tommy Flowers. Alan Mathison Turing also contributed to its design but the fact was that he was not directly involved in it.

People generally thought that the very first digital computers to use electricity were the Colossus, created in England in 1943, and the ENIAC, made in the US in 1945.

6. The first digital computer built with IC chips is known as- [Uttarakhand P.C.S.(PRE) 2006]

Correct Answer: (d) IBM System/360
Solution:The first digital computer built with IC chips is known as IBM system/360 . It was a groundbreaking family of mainframe computers that utilized solid-state transistors and, more significantly, integrated circuits in their later models. It was developed in 1964.

7. The main board of the computer is known as: [Uttarakhand P.C.S. (MAINS) 2002]

Correct Answer: (b) Motherboard
Solution:A motherboard is a physical arrangement in a computer that contains the computer's basic circuitry components. The chipset is the main part of the motherboard. It manages the data flow between processor, memory, and peripherals. The chipset plays a crucial role in determining system performance.

8. A pen drive is: [Uttarakhand P.C.S.(PRE) 2006]

Correct Answer: (c) A removable secondary storage unit.
Solution:A pen drive or a  USB flash drive is a portable data storage device. Pen drives have replaced the floppy drive of the past and have became the most popular data-storage devices among consumers. It is smaller and handy.

9. Mouse is : [Uttrakhand U.D.A. / L.D.A.(PRE) 2007]

Correct Answer: (c) Input device
Solution:A mouse is a  hardware input device that was invented by Dought Engelbart in 1963. The mouse allows an individual to control a pointer in a graphical user interface (GUI) and manipulate on-screen object such as icons, files, and folders.

10. Which of the following is not an output device? [Uttarakhand P.C.S. (MAINS) 2006]

Correct Answer: (c) Mouse
Solution:

A mouse is an input device that allows you to interact with the computer by controlling the cursor on the screen.

The other options are output devices:

  • Monitor: Displays visual information.
  • Printer: Produces hard copies of digital documents.
