ICT Fundamentals for Libraries Questions and Answers

Answer: C

The ISDN services are teletext, voice mail and video conference, so the answer is C.

The integrated services digital network carries voice, data, text and video on the same digital line. Services such as teletext, voice mail and video conferencing can be offered over it.

RSS (i) is a web feed format for syndicating content and has nothing to do with ISDN, so options A, B and D, which include it, are wrong.

Answer: B

The key says that planting the 'Trojan Horse' virus in a computer network is tampering, decryption and intrusion, so the answer is B.

A Trojan horse is a program that looks harmless but enters the system, alters or tampers with data, and opens the way for an unauthorised person to get in. In the key these are the three terms (ii), (iii) and (iv).

The key does not accept hacking (i), the term for breaking into a system by a person, so options A, C and D are rejected.

Answer: A

The assertion is true and the reason is false, so the answer is A.

Hypermedia extends hypertext by linking text with images, sound, video and other media, so a combination of hypertext and hypermedia carries all of these kinds of information (A).

The reason says that hypermedia information is represented in a linear fashion. The opposite is true: hypermedia is non-linear, since the user follows links in any order. So the reason is false, and options B and C, which accept it, are wrong.

Answer: C

The order of increasing data storage capacity in the key is cartridge, CD-ROM, DVD and Blu-ray disc, so the answer is C.

A CD-ROM holds about 650 to 700 MB, a single-layer DVD about 4.7 GB and a Blu-ray disc 25 GB or more. The key puts the cartridge, a tape or disk cartridge of small capacity, first.

The other orders place the Blu-ray disc, which has the largest capacity of the four, before the others or put the CD-ROM after the DVD, which cannot be right.

Answer: B

The correct matching is pen drive with storage device, i-Pad with computing device, Wi-Fi modem with communication device and cloud computing with web server device, so the answer is a-iii, b-iv, c-i, d-ii, option B.

A pen drive stores data. An iPad is a tablet computer. A Wi-Fi modem connects devices to a network, so it is a communication device, and cloud computing provides services from servers on the web.

The other codes assign the pen drive to communication or computing or place the iPad as a storage device, which they are not.

Answer: B

The correct matching is Informix with DBMS software, Omni Page with OCR software, TIFF viewer with image software and Team Viewer with remote login software, so the answer is a-iii, b-iv, c-i, d-ii, option B.

Informix is a database management system. OmniPage converts scanned images of text into editable text, which is optical character recognition. A TIFF viewer displays image files, and TeamViewer gives remote access to another computer.

Each other code assigns one of these to a wrong class of software.

Answer: C

The keyed answer is option C: a relational database is one in which manipulation commands relate records in different fields. In a relational database, data are held in tables, and commands such as join and select link records across tables on common fields, so the relation is between data held in different places.

Option A describes a related work in bibliographic terms, not a database. Option B describes a relationship symbol or operator, which is a notation in indexing and not a database design. Option D, all of the above, fails because A and B are wrong. Only option C describes the working of a relational database.

Answer: B

The factors that influence the organisation of computer files are speed of access, storage space and file volatility, option B, statements (i), (ii) and (iv). Speed of access decides whether a sequential, indexed or direct organisation is chosen. Storage space limits how records can be packed. Volatility, how often records are added, changed or deleted, decides how easily the file can be kept current.

Fixed-length fields (iii) describe how a record is laid out, which is a design detail inside a file, not a factor that decides the type of organisation. Options A, C and D contain statement (iii), and so are wrong.

Answer: C

The major problems of information and communication technology are information overload, information insecurity and lack of control over communication, option C, statements (i), (ii) and (iv). Too much information, threats to its safety and privacy, and the difficulty of controlling what flows across networks are the problems usually discussed.

Lack of innovative technologies (iii) is not a problem of ICT but the opposite, since the technology changes constantly. Options A and B leave out one of the three problems, and option D includes statement (iii), so each of them is wrong.

Answer: D

The open source content management systems in the list are Drupal, Joomla and OpenCms, option D, statements (i), (iii) and (iv). Each is free software whose source code is open and can be modified.

Atex (ii) is a commercial publishing system sold by a vendor, so it is not open source. Options A, B and C all include it, and so they are wrong. The key to such a question is to find the one proprietary product among the names.
