Network Fundamentals
- A LAN (Local Area Network) is a computer network that spans a small geographical area, usually within a building or campus, whereas a WAN (Wide Area Network) covers a larger geographical area, such as cities or countries.
Data Communication
- Data communication is the transmission and reception of data between devices through a medium, such as cables or wireless links.
Network Examples
- Example of a network: A company's office network, which connects computers and devices within the office building.
Network Functions
- The primary function of networks is to enable communication, resource sharing, and information exchange between devices.
WAN Composition
- WANs consist of multiple LANs connected through routers, switches, and other networking devices.
Personal Area Network (PAN)
- A PAN is a computer network used for communication among devices close to a person's body, such as a wireless headset and smartphone.
Wireless Local Area Network (WLAN) Advantages
- WLANs offer advantages such as mobility, ease of installation, and cost-effectiveness.
Network Security Risks
- Risks to computer network security include unauthorized access, data breaches, and malware attacks.
LAN Cost-Effective Resource Sharing
