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. This integration allows different functionalities to coexist and operate together, leading to more versatile and powerful tools. For example, a smartphone converges mobile communication, computing, and internet access into one device.

Question 2.

How to make the convergence technology possible?
Solution: Making technology convergence possible requires several key elements. These include robust, high-bandwidth networks capable of handling large data volumes, and widespread access to high-speed Internet. Additionally, advancements in software and hardware that allow for the compression of data and the seamless combination of multiple technologies are crucial. These advancements enable new methods of connectivity and interaction between different technological domains.

Question 3.

Name the technology that allows to send and receive the signals of various devices.
Solution: Communication technology is the field responsible for enabling the sending and receiving of signals for various devices. This includes technologies that facilitate the transmission of information across different media and distances, such as radio waves, television signals, telephone communications, and satellite transmissions, connecting one location to another.

Question 4.

How is computer technology differ from communication technology?
Solution: Computer technology primarily focuses on the design, construction, and programming of computer systems and their software. In contrast, communication technology is concerned with the design, construction, and maintenance of systems that facilitate the transmission and reception of information. While computer technology deals with processing and storing data, communication technology deals with how that data is sent and received across distances.

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, rather than traditional broadcast methods.

Question 6.

What do you understand by E-Banking?
Solution: E-Banking, or electronic banking, refers to the provision of banking products and services directly to customers through electronic and interactive communication channels. It involves using digital platforms and networks to conduct financial transactions, such as checking balances, transferring funds, and paying bills, without needing to visit a physical bank branch.

Question 7.

Name the method used for exchanging digital messages.
Solution: Electronic mail, commonly known as e-mail, is the primary method used for exchanging digital messages over computer networks. It allows users to send and receive text, documents, images, and other digital files to and from other users across the globe.

Question 8.

What is the use of Voice over Internet Protocol?
Solution: Voice over Internet Protocol (VoIP) is a technology that enables users to make and receive telephone calls using the Internet instead of traditional telephone lines. It converts analog voice signals into digital data packets that are transmitted over the internet, often providing cost savings and additional features like video conferencing.

Question 1.

Describe 3C's of technologies.
Solution: The '3Cs' of technologies refer to three fundamental domains that are central to modern technological convergence:

1. Computer Technology: This involves the design, construction, and programming of computer systems. It encompasses hardware development, software engineering, and the creation of applications that process and manage information.

2. Communication Technology: This field focuses on the design, construction, and maintenance of systems used for transmitting and receiving information. It includes technologies like radio, television, telephone networks, and the internet, often referred to as Information and Communication Technology (ICT).

3. Content Technology: This domain deals with the creation, display, storage, and distribution of digital content. When information is processed by computers, it becomes digital content that can be universally shared and communicated through various media such as websites, CDs, DVDs, and pen drives.

Question 2.

Define television and radio broadcasting system
Solution: A television broadcasting system is a complex network designed to transmit visual and auditory content (programs) to a wide audience via electromagnetic waves or digital signals. It involves content creation, signal encoding, transmission, and reception by television sets. Similarly, a radio broadcasting system transmits audio content (programs) to listeners using radio waves. It includes studios for content production, transmitters to broadcast the signals, and radio receivers used by the public to tune into the broadcasts.

Common mistakes

  • Confusing the distinct roles of Computer, Communication, and Content technologies.
  • Not fully grasping the necessity of high-bandwidth networks for convergence.
  • Overlapping definitions of IT and Communication Technology without clear distinction.

Revision tips

  • Focus on understanding the '3Cs' and their individual contributions to convergence.
  • Review the examples of convergence like E-Banking and VoIP to solidify understanding.
  • Pay attention to the requirements for making convergence possible, such as network infrastructure.
  • Practice explaining the difference between computer and communication technology in your own words.
