ICT Fundamentals for Libraries Questions and Answers

Q: Assertion (A) : Work about Big data could also be found in Library.Reason (R) : Library data needs to be transformed into information or knowledge.

Both (A) and (R) are true.Assertion A: libraries now hold and generate big data, including large digital collections, circulation and usage logs, research data and catalogue records at scale, and library work increasingly involves managing and analysing such data, so work about big data can be found in libraries.Reason R: like any data, library data have value only when they are processed and analysed into information and knowledge, for example to understand use and plan services.Both statements are true, so the options calling either one false are wrong.

Q: Assertion (A) : Cloud computing does not facilitate external collaboration.Reason (R) : Cloud computing causes libraries to provide innovative web services for users.

(A) is false, but (R) is true.Assertion A is false: cloud computing makes external collaboration easier, since documents, data and applications stored in the cloud can be shared and worked on by people in different places and organisations at once.Reason R is true: cloud platforms let libraries offer innovative web services, such as cloud-hosted catalogues and discovery tools, digital repositories and shared storage, without maintaining their own servers.The options calling A true or R false are therefore wrong.

Q: Which among the following is a free audio book site ?

The free audiobook site is Librivox.LibriVox, founded in 2005, offers free audiobooks of public-domain works recorded by volunteers, and makes them available for download without charge.Ebrary was a commercial e-book platform for libraries (now part of ProQuest Ebook Central), Virtua is an integrated library management system from VTLS, and Amazon sells audiobooks through Audible rather than offering a free audiobook library.

Q: Assertion (A) : TCP is called as a reliable delivery protocol.Reason (R) : TCP makes sure that whatever is sent by the sending machine is received intact by the destination.Codes :

Both (A) and (R) are true.TCP (Transmission Control Protocol) is called a reliable, connection-oriented delivery protocol. It numbers the bytes it sends, requires acknowledgements, retransmits lost segments, discards duplicates and reorders segments, so the receiving application gets the data intact and in order.That is exactly what the reason states, so both statements are true. UDP, by contrast, is the unreliable, connectionless protocol of the transport layer.

Q: Virtual reality is described as an experience, which encompasses senses such as :(i) Sight(ii) Touch(iii) Feeling(iv) SmellCodes :

The key's answer is (i) Sight and (ii) Touch.Virtual reality creates an immersive, computer-generated environment. The senses it mainly engages are sight, through head-mounted displays, and hearing, with touch added through haptic gloves and controllers that give tactile feedback. Of the senses listed, sight and touch are the ones VR systems commonly address.'Feeling' is not a sense distinct from touch, and smell is only rarely simulated in experimental systems, so codes including (iii) or (iv) are wrong.

Q: Which term was coined by Prof. Harald Haas while giving a talk on "wireless data from every light" ?

Prof. Harald Haas coined the term Li-fi.In his 2011 TED Global talk on 'wireless data from every light bulb', Harald Haas of the University of Edinburgh demonstrated transmitting data by rapidly modulating the light of an LED, too fast for the eye to notice, and named the technology Li-Fi (light fidelity).Wi-Fi uses radio waves and was named long before; electromagnetic waves and optical cables are general terms, not ones he coined.

Q: Which type of protocol is used by Interface for public data network (PDN) ?

The interface for public data networks is X.25.ITU-T recommendation X.25 defines the interface between data terminal equipment and a packet-switched public data network. It was the standard protocol suite for public packet-switched networks from the 1970s, and Indian networks such as I-NET used it.X.12 (properly ANSI X12) is an electronic data interchange standard, and X.20 deals with an interface for start-stop transmission on circuit-switched networks; neither is the PDN packet interface. X.13 is not the relevant recommendation.
