6.3.2. Modern Communication Technologies

The list of modern communication technologies is long and every other day we hear of innovation in the existing technology. Following are some of the major types of modern communication technologies used primarily for extension purposes.

This chunk introduces the concept of modern communication technologies, indicating that they are constantly evolving and being updated. It serves as a preliminary notice to students that the world of communication is dynamic, with new advancements emerging frequently. By mentioning that various types are used for extension purposes, it lays the groundwork for further exploration of specific technologies.

Think of your smartphone or computer; every month or so, you might receive updates or hear about new applications that can help you communicate in different ways, like social media platforms adding new features to improve how you share and connect.

Computers are classified as mainframes (large and costly), mini computers (less powerful) and micro-computers (based on microchip technology). This classification is based on their power, speed of executing a set of instructions and the amount of memory available to store data as well as degree of interconnectivity that the computer offers.

This chunk explains the classification of computers, emphasizing the differences in size, power, and capability. It notes that computers range from large mainframes that are expensive and powerful to micro-computers that are more common and portable. Understanding these classifications can help students grasp how computers can be tailored for different tasks and uses within communication technology.

Imagine a large library (mainframe) that stores enormous amounts of information and can handle many visitors at once, compared to your home bookshelf (micro-computer) where you have a few select books for everyday reading. The library serves a broader purpose, while the bookshelf is practical for personal use.

Bluetooth Technology is a low-cost, short-range radio frequency (RF) link between mobile PCs, mobile phones and other portable devices capable of transmitting voice and data at the rate of 1 Mbps, which is from three to eight times the average speed of parallel and serial ports, respectively. It can transmit through solid, non-metal objects.

This chunk focuses on Bluetooth technology, clarifying that it allows for wireless communication between devices at short ranges. It highlights its low cost and effectiveness in transmitting data and voice quickly, even through obstacles. Understanding Bluetooth's capabilities aids students in appreciating how everyday devices can interact seamlessly without physical connections.

Think of Bluetooth like a small, friendly neighborhood that allows neighbors (devices) to chat with each other without having to go to each other's houses. Instead of running a wire between homes, they can simply send messages back and forth over the air wherever they are located within the neighborhood.

Interactive video refers to a video system which is a combination of computer and video. It uses multimedia approach, i.e., text, still photographs, video, audio, slides, overheads, etc. The messages stored in different forms are received by the users as per their choice.

This chunk details interactive video technology, explaining that it combines various media types. This feature allows users to choose how they want to interact with content, making learning more engaging. The multimodal approach can be seen as a way to cater to different learning styles, enhancing understanding and retention.

Imagine watching a cooking show where you can click on the ingredients list and see a video of how to prepare them, while also reading tips on the side. This interactive experience is like having a personal cooking assistant that adapts to how you learn best.

Teleconferencing is interactive group communication. It refers to a system meant for creating dialogue between geographically dispersed participants and physically distant people. Advances in telecommunication have made it possible to hold meetings without travelling to long distances.

This chunk describes teleconferencing, which enables real-time communication among groups that are not in the same location. This technology facilitates dialogues and meetings without the need for travel, making collaboration more efficient and accessible. Understanding teleconferencing is crucial for students as it exemplifies how modern technology can enhance productivity and connectivity.

Think of teleconferencing like a virtual classroom where students from different cities can join the same lesson without leaving their homes. It’s like a magic portal that connects everyone for discussions and learning, regardless of their physical locations.
