1. Objectives Define what a computer network is. Explain the uses and benefits of computer networks. Describe workgroup computing and groupware. Differentiate between server and client computers.

2. What is a Computer Network? Consists of two or more connected computers. Shares information and resources (e.g., printers, hard disks). Connected through communication media (cables or wireless). Can be in the same room, building, or different places. Used at home, in businesses, and educational institutes.

3. Example of Computer Network The Internet: allows millions of users worldwide to share information.

4. Uses/Benefits of Computer Networks Access shared data. Share devices like printers and hard disks. Send emails with attachments. Communicate with people globally. Share software over a network with multiple users.

5. Workgroup Computing Group of people working together on a task using a computer network. Called collaborative computing. Members can be in different places. Share ideas and experiences, files, pictures, sounds, videos, and graphics. Efficient data and information transfer. Important for research and development.

6. Groupware Software used for workgroup computing. Used to share information about projects online. Facilitates collaboration with colleagues.

7. Server Computer Provides services to computers and devices in a network. More powerful than other network computers. Services include: - Controlling access to hardware, software, and data. - Centralized storage. - Processing data. - Sharing software. - Managing network traffic.

8. Client Computer Connected to a server to access resources. Sends requests to the server for resources. Less powerful than a server.

9. Conclusion Computer networks enable resource sharing and communication. Workgroup computing and groupware enhance collaboration. Servers and clients have distinct roles in a network.
