Detailed Summary of Modern Communication Technologies
Modern communication technologies represent the significant changes in how we convey information using various mediums rapidly evolving due to technological advancements. In this section, we first explore the definition of communication technology, which encompasses the technologies designed to manage and facilitate communication.
The classification of these technologies is essential; they are primarily divided into two groups: cable-based and wireless technologies. Cable technologies, such as landline telephones and simple PCs without internet connectivity, tend to be more affordable and less complex. In contrast, wireless technologies like mobile phones and satellite communications require more advanced infrastructure and can often be costlier.
The discussion also covers notable communication technologies that have transformed information dissemination, including:
- Micro Computers - These are categorized based on size and capabilities, significantly aiding information processing and record-keeping tasks.
- Video Text - An innovative service allowing users to access electronic text data transmitted to their TV sets.
- E-mail - A convenient electronic mail system that enables efficient communication across distances.
- Interactive Video - This combines computer and video technologies to allow user choice in information access.
- Teleconferencing - This method supports group discussions among participants who are geographically scattered.
Overall, modern communication technologies have not only increased the efficiency of communication but have also made it widely accessible, thus playing a vital role in connecting people across various sectors.

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.
Detailed Explanation
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.
Examples & Analogies
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

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.
Detailed Explanation
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.
Examples & Analogies
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.
