31. Unicode encoding scheme represents a character as a group of โ€“ [R.A.S/R.T.S. (Pre) 2015]

Correct Answer: (a) 16 bits
Solution:

Unicode represents each character by 2 bytes or 16 bits.

32. The basic unit of quantum information is โ€“ [Jharkhand P.C.S. (Pre) 2017]

Correct Answer: (d) QUBIT
Solution:

In quantum computing, a 'qubit' (or quantum bit) is the basic unit of quantum information โ€“ the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, e.g. spin of the electron in which two levels can be taken as spin up and spin down.

33. 33. Which one of the following is the context in which the term 'qubit' is mentioned? [I.A.S. (Pre) 2022]

Correct Answer: (b) Quantum Computing
Solution:

In quantum computing the information is encoded in qubits. A qubit (or quantum bit) is the counterpart in quantum computing to the binary digit or bit of classical computing. A qubit is a two-state quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics.

34. Consider the following statements and select the correct answer from the codes given below: [M.P.P.C.S. (Pre) 2008]

35. An exclusively private network used by employees of a company in a single location will be classified as โ€“ [M.P.P.C.S. (Pre) 2008]

Correct Answer: (b) Local Area Network
Solution:

A local area network (LAN) is a computer network that interconnects computers within a limited area such as home, school, computer laboratory or office building by using network media.

36. LAN means โ€“ [Uttarakhand U.D.A/L.D.A. (mains) 2006]

Correct Answer: (b) Local Area Network
Solution:

A local area network (LAN) is a computer network that interconnects computers within a limited area such as home, school, computer laboratory or office building by using network media.

37. Ethernet is an example of โ€“ [M.P.P.C.S. (Pre) 2017]

Correct Answer: (b) LAN
Solution:

Ethernet is a network protocol that controls how data is transmitted over LAN. Technically it is referred to as the IEEE 802.3 protocol.

38. In a database, field is โ€“ [M.P.P.C.S. (Pre) 2008]

Correct Answer: (d) Category of information
Solution:

In a database, field is a category of information.

39. Which part of Central Processing Unit (CPU) performs calculations and makes decisions? [Jharkhand P.C.S. (Pre) 2023]

Correct Answer: (d) Arithmetic Logic Unit
Solution:

Arithmetic Logic Unit (ALU) is responsible for performing calculations and contains decision-making mechanisms. In the computer system, ALU is a main component of the central processing unit (CPU), which performs all arithmetic and logic operations that must be performed on instruction words.

40. With relation to computers ALU means : [Uttarakhand P.C.S. (Pre) 2005]

Correct Answer: (b) Arithmetic Logic Unit
Solution:

Arithmetic Logic Unit (ALU) is responsible for performing calculations and contains decision-making mechanisms. In the computer system, ALU is a main component of the central processing unit (CPU), which performs all arithmetic and logic operations that must be performed on instruction words.
