ICT Fundamentals for Libraries Questions and Answers

Q: Which of the following is not a network protocol ?

The answer is Z 39.50.HTTP, SMTP and TCP/IP are the communication protocols on which the Internet runs: TCP/IP carries data between machines, HTTP moves web pages and SMTP moves e-mail. Z39.50 is an ANSI/NISO standard for information retrieval: it lets one library system search another library's catalogue or database and get records back in a common form.Z39.50 is itself a client-server protocol, but it is an application standard for searching bibliographic databases that runs on top of TCP/IP rather than a networking protocol in its own right, which is the distinction the question draws. The other three are the textbook examples of network protocols.

Q: "Live Journal" can be used for the creation of :

LiveJournal is used to create a Blog.LiveJournal, launched in 1999, is a social networking service on which users keep journals or blogs: dated posts shown in reverse chronological order, with comments from friends and communities. It was one of the early blogging platforms, alongside Blogger.RSS is a feed format that blogs and news sites use to syndicate their updates; it is a technology, not something a LiveJournal user creates as content. A wiki, such as Wikipedia, is built with wiki software that lets many people edit the same pages. Facebook is a separate social network.

Q: Process of reading data from permanent store and writing it to computer's main store is called :

The process is called loading data.Loading means reading data or a program from permanent storage, such as a hard disk, into the computer's main memory (RAM) so the processor can work on it. When a document is opened, it is loaded from disk into memory.Saving is the reverse movement, writing data from main memory to permanent storage so it survives after the power is switched off. 'Writing data' and 'reading data' each name only one half of the operation described, which reads from the permanent store and writes to main memory, so the single term for the whole movement is loading.

Q: Thick coax cable has maximum .......................... segments.

Thick coaxial cable allows segments of at most 500 m.Thick coax (thicknet) is the cable of the original 10BASE5 Ethernet. The name encodes its limits: 10 Mbps, baseband signalling, and a maximum segment length of about 500 metres before a repeater is needed.Thin coax (thinnet, 10BASE2) is limited to about 185 metres, roughly the '2' of its name, and twisted-pair Ethernet (10BASE-T) to 100 metres per segment, which is the trap in the 100 m option. 10 m and 50 m are far shorter than any of these standard Ethernet segment limits.

Q: Multiplexing is used in :

In the classic textbook pairing, multiplexing is used in circuit switching.In a circuit-switched network such as the telephone system, a dedicated channel is set up between two parties for the whole call. The trunk lines between exchanges carry many such circuits at once by frequency-division or time-division multiplexing, each call getting its own frequency band or time slot. This is the textbook pairing of multiplexing with switching.Packet-switched networks also share links, but by statistical multiplexing of packets, which textbooks treat under packet switching rather than as multiplexing in this classic sense. On that classic pairing the packet-switching options and 'data switching', which is not a standard switching type, are marked wrong.

Q: Assertion (A) : Many of the big libraries are going for cloud computing.Reason (R) : Cloud computing has helped them to avoid locally hosting and operating multiple servers.

The answer is Both (A) and (R) are true.The Assertion is true: many large libraries have moved their library systems, discovery services and repositories to cloud-hosted platforms, OCLC's WorldShare and Ex Libris Alma being common examples.The Reason is also true, and it is the main attraction of the cloud: the vendor hosts and runs the servers, so the library no longer has to buy, house, power, patch and back up several servers of its own.Since both statements are true, the options calling either of them false are wrong. (This code set has no separate option about whether R explains A.)

Q: "Jotspot" is used for the creation of :

JotSpot was used to create a wiki.JotSpot, founded in 2004 by Joe Kraus and Graham Spencer, was a hosted application wiki: groups could create and edit shared pages and add structured applications such as calendars and project trackers. Google bought it in 2006 and rebuilt it as Google Sites.It was not a blogging service like Blogger or WordPress, not a feed format like RSS, and not a social network like Facebook.

Q: In OSI model which layer is in between Physical layer and Network layer ?

The layer between the Physical and Network layers is the Data link layer.The seven OSI layers, from the bottom: 1 Physical, 2 Data link, 3 Network, 4 Transport, 5 Session, 6 Presentation, 7 Application. The Data link layer packs bits into frames, adds physical (MAC) addresses and checks for transmission errors on a single link, before the Network layer routes packets between networks.The Transport layer (4) sits above the Network layer, and the Session (5) and Presentation (6) layers are higher still, so none of them lies between layers 1 and 3.

(ii) Facebook
(iii) Intelligent Web
(iv) RSS Feeds

A.(i) and (ii) are correct
B.(i) and (iii) are correct
C.(ii) and (iii) are correct
D.(iii) and (iv) are correct

Exam Year(s)

MH SET - 2018, SET Exam - 2018,

Answer: B

The ones that are not Web 2.0 tools are ontologies and the intelligent web, so the answer is (i) and (iii) are correct.

Ontologies and machine-understandable, 'intelligent' web services belong to the Semantic Web, often called Web 3.0, which aims to let software reason over the meaning of data.

Facebook (a social networking site) and RSS feeds (syndication of new content) are standard Web 2.0 tools, built on user participation and sharing, so codes containing (ii) or (iv) are wrong.
