Questions and Solutions

Question 1.

What do you mean by convergence of technology?
Solution: Convergence of technology refers to the phenomenon where two or more distinct technologies integrate and interact within a single device or system, leading to new functionalities and enhanced user experiences.

Question 2.

How to make the convergence technology possible?
Solution: Making convergence technology possible requires several key components: high-bandwidth networks for efficient data transfer, high-speed internet access for connectivity, advanced compression techniques for software and hardware, and the development of devices that integrate multiple technologies while leveraging new connectivity methods.

Question 3.

Name the technology that allows to send and receive the signals of various devices.
Solution: Communication technology is the field dedicated to the design, construction, and maintenance of systems that enable the sending and receiving of signals. This allows various devices, such as radios, televisions, telephones, and satellites, to transmit and receive information from one location to another.

Question 4.

How is computer technology differ from communication technology?
Solution: Computer technology primarily involves the activity of designing, constructing, and programming computer systems. In contrast, communication technology focuses on the design, construction, and maintenance of systems used for transmitting and receiving information, such as networks and broadcasting equipment.

Question 5.

Name the term used for digital distribution of television content over Internet.
Solution: The term used for the digital distribution of television content over the Internet is Internet television or online television. This allows viewers to watch TV programs and shows through web browsers or dedicated applications using an internet connection.

Question 6.

What do you understand by E-Banking?
Solution: E-Banking, or electronic banking, is defined as the automated delivery of banking products and services directly to customers through electronic and interactive communication channels. It allows customers to perform various banking transactions remotely using digital platforms.

Question 7.

Name the method used for exchanging digital messages.
Solution: Email (electronic mail) is the primary method used for exchanging digital messages. It allows users to send and receive text, documents, images, and other files electronically over computer networks, typically the internet.

Question 8.

What is the use of Voice over Internet Protocol?
Solution: Voice over Internet Protocol (VoIP) technology enables users to make and receive telephone calls using the Internet instead of traditional telephone lines. This allows for voice communication over data networks, often at a lower cost and with additional features.

Question 1.

Describe 3C's of technologies.
Solution: The '3Cs' of technologies are:
  1. Computer Technology: This involves the design, construction, and programming of computer systems. The innovation in computer technology has led to the integration of communication features into devices like televisions and mobile phones.
  2. Communication Technology: This is the activity of designing, constructing, and maintaining communication systems, often referred to as ICT (Information and Communication Technology). It encompasses devices and applications like radio and television that facilitate the sending and receiving of signals.
  3. Content Technology: This technology deals with how content is displayed over the Internet through websites and stored using various media like CDs, DVDs, and pen drives. When information is processed by a computer, it becomes digital content that can be universally shared and communicated.

Question 2.

Define television and radio broadcasting system
Solution: A television broadcasting system transmits visual and audio signals over the airwaves or through cable networks to receivers (televisions) that display the content. Similarly, a radio broadcasting system transmits audio signals to receivers (radios). Both systems rely on communication technology to distribute content to a wide audience, enabling mass communication.

Common mistakes

  • Confusing the distinct roles of Computer Technology and Communication Technology.
  • Not fully grasping how Content Technology facilitates digital sharing.
  • Underestimating the importance of network infrastructure for convergence.

Revision tips

  • Review the definitions of the '3Cs' and their interrelations.
  • Focus on understanding the practical applications of convergence like E-Banking and VoIP.
  • Create a mind map connecting different technologies discussed in the chapter.
