Information and Communication Technology Multiple Choice Questions (MCQs) for Assistant Professor, UGC NET, CTET, TGT, PGT and all other Teacher’s Recruitment Exams.

Mankind has entered the information age from an industrial age that prevailed till a few years ago. This change is expected to have a profound effect on the way we live, make money and deal with wars. It would therefore be useful to examine the nature of information and the information technology that is at the root of future opportunities, challenges and competition. Information has been there since beginning. Information technology was also there. But it is computer, which has made information technology so popular.

Information and Communication Technology For Assistant Professor, UGC NET

Information and Communication Technologies are defined as all devices, tools, content, resources, forums, and services, digital and those that can be converted into or delivered through digital forms, which can be deployed for realising the goals of teaching learning, enhancing access to and reach of resources, building of capacities, as well as management of the educational system.

These will not only include hardware devices connected to computers, and software applications, but also interactive digital content, internet and other satellite communication devices, radio and television services, web based content repositories, interactive forums, learning management systems, and management information systems.

These will also include processes for digitisation, deployment and management of content, development and deployment of platforms and processes for capacity development, and creation of forums for interaction and exchange.

India’s capabilities in the field of Information Technology provide not only an opportunity to participate vigorously and effectively in a globalizing world, but also to use it as a major vehicle for all-round socio-economic development of the country.

To ensure the benefits of an ICT-based knowledge economy India needs to adopt the two fold strategies: (i) a number of steps to ensure that the Indian IT industry grows at a fast pace in consonance with international trends: and (ii) to intend to take all possible measures to ensure that the benefits of his technology are meaningfully felt by the common people and reach to even in the remotest parts of the country.

The most basic hardware required for communication is the media through which data is transferred. There are several types of media, and the choice of the right media depends on many factors such as cost of transmission media, efficiency of data transmission and the transfer rate. We will describe some of these transmission media.

1. Twisted Pair Cable

The most common form of wiring in data communication application is the twisted pair cable. It consists of a pair of insulated conductors that are twisted together. The advantage of a twisted pair cable is providing better immunity from spurious noise signals. Twisted pair cable is used for communication upto a distance from 1 km and can achieve transfer rates of 1-2 megabytes per second.

But, as the speed increased the maximum transmission distance is reduced, and may require repeaters. Twisted pair cable is widely used in telephone networks and is increasingly being used for data.

2. Coaxial Cable

A coaxial cable consists of a solid conductor running coaxially inside a solid or braided outer annular conductor. The space between two conductors is filled with a dielectric insulating material.

Larger the cable diameter, lower is the transmission loss, and higher transfer speeds can be achieved. A coaxial cable can be used over a distance of about 1 km. and can achieve transfer rate of upto 100 megabytes per second.

A coaxial cable is of two types-a 75 ohm cable which is used by the cable TV operators and the 50 ohm cable which is used in high speed broadband network and is low loss cables.

3. Optical Fibre Cables

An Optical Fibre Cable carries signals in the form of fluctuating light in a glass or plastic fibre. An optical fibre cable consists of a glass or plastic core surrounded by a closing made of similar material but with a lower refractive index. The core transmits the light while the change in refractive index.

The core transmits the light while the change in refractive index between the core and the cladding causes total internal reflection, thus minimizing the loss of light from fibre. A light waves gave a much wider band width then the electric signal and are immune from electromagnetic interferences, this leads to high data transfer rates of about 1000 megabytes per second and can be used for long and medium distance transmission links.

4. Radio, Microwave and Satellite Channels

Radio, microwave and satellite channels are use electromagnetic propagation in open space. The advantage of these channels lies in their capability to cover large geographical areas and being inexpensive then the wired installation. The demarcation between radio, microwave and satellite channels lies in the frequencies in which they operate. Frequencies below 1000 MHz are radio frequencies and higher are the microwave frequencies. Radio frequency transmission may be below 30 MHz and thus the techniques of transmission are different. Owing to the characteristics of the ionosphere, frequencies below 30 MHz are reflected back towards the surface of the earth. Above 30 MHz propagation is one line-of-sight paths. Antennas are placed in between the line of sight paths to increase the distance.

Radio frequencies are prone to attenuations and, thus, they require repeats along the path to enhance the signal. Radio frequencies can achieve data transfer rates of 100 Kbps to 400 Kbps.

Microwave links would invariably use line-of-sight transmission with repeaters placed every 100-200 kms. Microwave links can achieve data transfer rates of about 100 Mbps. Satellite links use microwave frequencies is the order of 4-12 GHz with the satellite as a repeater. They can achieve data transfer rates of about 1000 Mbps.

5. Digital and Analog Transmission

Data is transferred from one point to another by means of electrical signals. These electrical signals may be in the form of digital and analog signals. In an analog signal, the transmitted power varies over a continuous range. For example, sound, light and radio waves. The amplitude of analog signals is measure in volts and frequency in Hertz. The telephone lines used for data communication in computer networks are usually analog data items.

In digital signals, the sequences of voltage pulses are represented in a binary form. These signals are either high or low; no intermediate phase is there in the digital signals. Computer-generated data is digital. When the digital data are to be sent over an analog facility, the digital signal must be converted to analog signals.

Following are the aim and objectives of ICT implementation in education:

1. To implement the principle of life-long learning / education.

2. To increase a variety of educational services and medium / method.

3. To promote equal opportunities to obtain education and information.

4. To develop a system of collecting and disseminating educational information.

5. To promote technology literacy of all citizens, especially for students.

6. To develop distance education with national contents.

7. To promote the culture of learning at school (development of learning skills, expansion of optional education, open source of education, etc.)

8. To support schools in sharing experience and information with others.
