Study Notes

Lesson 2: Communication

The lesson objective is to compare and contrast different online platforms, sites, and content to best achieve specific class objectives or address situational challenges.
Communication is the act of transferring information from one place to another. The classic communication system involves an information source, encoder, transmitter, receiver, decoder, storage, retrieval, and an information destination.
Communication in ICT can be synchronous or asynchronous.

Two Types of Communication in ICT

Synchronous communication occurs when people send data at the same time.
Asynchronous communication involves a time lag between sending and receiving data. The recipient takes in the information before responding.

Examples of Synchronous Communication

Online chat
Text-based communication
Audio-based communication
Video-based communication
Mobile technology
Conferences
Phones
Satellite
Television channels
Video conferencing

Examples of Asynchronous Communication

Discussion forums
Blogs
E-groups
Wikipedia (knowledge-based)
Google (search engine)
Mobile SMS
MMS
Podcasting

Importance of the Internet in ICT

The internet plays a crucial role in ICT, enabling global connectivity.
It connects computer networks using the TCP/IP protocol suite to link billions of devices worldwide.
It provides diverse application services, such as email, newsgroups, and the World Wide Web.

Types of Network Connection

Local Area Network (LAN): A network of devices in one physical location like a building, office, or home. LANs can range from small home networks to large enterprise networks.
Wide Area Network (WAN): A large network spanning across multiple locations. WANs facilitate communication and information sharing between devices across geographical distances.

Uses of the Internet

Searching for information
Accessing email services
Using commercial online services
Reading electronic books and publications
Holding video conferences
Sharing data and results quickly
Retrieving files and applications
Using various online programs

World Wide Web

The World Wide Web is an information system on the internet that allows documents to connect using hypertext links. This enables users to navigate between documents easily.
