Computer Fundamentals – Networking Basics

Understanding Networks

Networking allows computers to communicate and share resources. Key concepts include:

• LAN (Local Area Network): A network that connects computers within a limited area, such as a home or office.

• WAN (Wide Area Network): A network that spans a large geographic area, often connecting multiple LANs.

Basic Networking Devices

Essential networking devices include:

• Router: Connects multiple networks and directs data between them, allowing different networks to communicate and access the internet.

• Switch: Connects devices within a single network, enabling them to communicate with each other efficiently by forwarding data to the appropriate destination.
