Q50. What does MIME stand for in electronic messaging technology?

[MP SET Library and Information Science 2022]

1. Multipurpose Internet Mail Extensions
2. Mail Internet Mobile Extensions
3. Mouse Extension Input Motherboard
4. Mobile Input Mail Extensions

Answer: A. Multipurpose Internet Mail Extensions

Explanation: Multipurpose Internet Mail Extensions permits email to carry attachments and content types beyond plain ASCII text, including images, audio and encoded files. MIME specifies headers and content encoding so receiving applications can interpret and display the message’s different parts.

Q49. Which network protocol is designed for standardised searching and retrieval from remote bibliographic databases?

[MPPSC Assistant Professor, Library and Information Science 2022, Paper II]

1. HTTP
2. FTP
3. SNMP
4. Z39.50

Answer: D. Z39.50

Explanation: Z39.50 is a client-server protocol used for searching and retrieving records from information systems, especially library catalogues. HTTP mainly transfers web resources, FTP exchanges files, and SNMP monitors and manages network devices rather than supporting this specialised search interface.

Q48. In basic networking terminology, bandwidth commonly indicates what?

[MPPSC Assistant Professor, Library and Information Science 2022, Paper II]

1. The physical separation between devices
2. A computer’s data-storage volume
3. Only the radio-frequency range in every context
4. Maximum data-transfer capacity of a connection

Answer: D. Maximum data-transfer capacity of a connection

Explanation: In everyday networking, bandwidth describes the data-carrying capacity of a link, usually expressed in bits per second. In signal theory, bandwidth also describes a frequency span. The recruitment question uses the common internet-connection speed or capacity sense.

Q47. The Semantic Web is conventionally associated with which version of the web?

[MPPSC Assistant Professor, Library and Information Science 2022, Paper II]

1. Web 1.0
2. Web 2.0
3. Web 3.0
4. Web 4.0

Answer: C. Web 3.0

Explanation: The Semantic Web vision adds machine-readable structure and meaning to online information. It has commonly been described as part of Web 3.0 in educational material, though contemporary Web3 also refers to decentralisation and blockchain technologies, which are not identical concepts.

Q46. Which body develops and promotes standards for the internet’s protocol suite?

[MPPSC Assistant Professor, Library and Information Science 2022, Paper II]

1. Internet Engineering Task Force
2. International Organization for Standardization
3. International Telecommunication Union
4. Institute of Electrical and Electronics Engineers

Answer: A. Internet Engineering Task Force

Explanation: The Internet Engineering Task Force develops widely used internet standards through open working groups and Requests for Comments. Organisations such as ISO, ITU and IEEE also develop technical standards, but IETF is particularly associated with TCP/IP internet protocols.

Q45. Which early commercial online system is recognised for pioneering worldwide information retrieval services?

[MP SET Library and Information Science 2022]

1. DuckDuckGo
2. Google
3. DIALOG
4. EBSCO

Answer: C. DIALOG

Explanation: DIALOG was an influential early commercial online information retrieval service developed in the 1960s. It gave users remote access to searchable bibliographic and other databases before the modern web became widespread. Google and DuckDuckGo emerged considerably later as web search services.

Q44. Which programming language was central to Japan’s original Fifth Generation Computer Systems initiative?

[Rajasthan Gram Vikas Adhikari, 27 December 2021, Shift 1]

1. ALGOL
2. COBOL
3. C
4. PROLOG

Answer: D. PROLOG

Explanation: Prolog is a logic programming language based on facts, rules and logical queries. Japan’s Fifth Generation Computer Systems project emphasised logic programming and inference technologies for knowledge processing. Its direction contrasted with the procedural style of languages such as C and COBOL.

Q43. How many bits make up an IPv4 address?

[SSC CHSL, 9 August 2021, Shift 2]

1. 32
2. 24
3. 16
4. 12

Answer: A. 32

Explanation: IPv4 addresses are 32 bits long and are conventionally displayed as four decimal octets separated by dots. IPv6 addresses, by comparison, use 128 bits. This distinction explains why IPv6 offers a vastly larger theoretical address space than IPv4.

Q42. What does the abbreviation JPEG expand to?

[SSC CHSL, 6 August 2021, Shift 3]

1. Joint Photography Exports Group
2. Joint Pixel Experts Group
3. Joint Photographic Experts Group
4. Joint Pixel Exports Group

Answer: C. Joint Photographic Experts Group

Explanation: JPEG expands to Joint Photographic Experts Group, the standards group associated with a widely used image compression format. JPEG is particularly effective for photographic content, where some loss of information may be acceptable to reduce file size significantly.

Q41. Which extension usually denotes a temporary file?

[SSC CHSL, 12 April 2021, Shift 1]

1. .tmp
2. .txt
3. .tnt
4. .tar

Answer: A. .tmp

Explanation: Many programs use the .tmp filename extension for intermediate or temporary data generated during processing. Such files may be discarded when no longer required. By comparison, .txt is plain text and .tar is an archive format often used on Unix-like systems.
