Study Notes
- A network is a group of linked computers which can range from two on the same desk to thousands across the world.
- Network users can share hardware, access data on other computers, and run programs stored on the network.
Network Components
- Networks consist of nodes (computers and devices), a connecting medium (cables or wireless), routers (for sending messages), and switches (for path selection).
Network Types
- LAN (Local Area Network) is located in a limited space like a building or campus.
- WAN (Wide Area Network) operates in a larger area, potentially reaching most of the world as a collection of LANs.
Communication Protocols
- Communications protocols control information exchange by defining the formats and rules computers must follow when communicating.
- Examples include Ethernet (for LANs) and the Internet Protocol Suite (for any computer network).
Advantages of Networks
- Networks facilitate communication through emails, texts, phone/video calls, and videoconferencing.
- Networks allow users may access data and information stored on other computers.
Disadvantages of Networks
- Setting up networks can be difficult, and they can be insecure due to viruses and computer worms.
- Networks may interfere with other technologies; power line communication can disturb radio communication and access technologies like ADSL.
