Correct Answer :   Data transfer rate

A CD-ROM drive, a device that can read information from a CD-ROM. CD-ROM players can be either internal, or external. There are a number of features that distinguish CD-ROM players, the most important of which is probably their speed or data transfer rate. CD-ROM players are generally classified as single-speed or some multiple of single-speed.

Correct Answer :   FAX

Value-added telecommunication services are telecommunications for which suppliers “add value” to the customer’s information by enhancing its form or content or by providing for its storage and retrieval. FAX is not considered to be a Value-added telecommunication service.

Correct Answer :   multiplication

The ‘AND’ gate in computers has basic application of multiplication. It has two or more inputs and one output. An ‘AND’ gate produces an output of 1 if all the inputs are 1 if any of the inputs is zero then it produces an output of zero.

Correct Answer :   1959 – 1964

The period 1953-1964 is generally taken to be the period of second generation computers. Sometimes, 1946-1958 is supposed to be the period of first generation computers. By 1948, the invention of the transistor greatly changed the computer's development. The transistor replaced the large, cumbersome vacuum tube in televisions, radios and computers. As a result, the size of electronic machinery has been shrinking ever since. From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of computers. A second generation computer, the IBM 1401, captured about one third of the world market. IBM installed more than ten thousand 1401s between 1960 and 1964.

Correct Answer :   Local Area Network

A local area network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home.

Correct Answer :   Random Access Memory

Random Access Memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order. In contrast, other data storage media read and write data only in a predetermined order.

Correct Answer :   hyper text transfer protocol

The Hyper Text Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. HTTP is the protocol to exchange or transfer hypertext.

Correct Answer :   Multimedia

Multimedia is media and content that uses a combination of different content forms. This contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material. Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms.

Correct Answer :   they do not generate magnetic fields

Optical fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Besides, there are no radiated magnetic fields around optical fibers; the electromagnetic fields are confined within the fiber. Since fiber optics do not radiate electromagnetic energy, emissions cannot be intercepted.

Correct Answer :   Morphing

Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition. Most often it is used to depict one person turning into another through technological means or as part of a fantasy or surreal sequence.
