2.3 Classification of Network
Local Area Network (LAN)
A network that connects computers and devices in a limited geographical area such as a room, a floor or a building
Usually operated by individuals or organisations
Characteristics of LAN
Area of coverage: It covers a limited geographical area
Ownership: LANs are owned by single ownership
Cost of setup: The cost of setting up a LAN is usually low as compared to WAN as it is located over a smaller geographic area and does not require additional devices.
Importance of Local Area Network
The resources can be shared among different users. For example, many users on the network can use a single printer.
Data and software stored on the central server can be shared between all users on the network
Advantages
LAN provides faster data transfer rates compared to WANs.
LANs have lower latency compared to WANs. With shorter distances between devices the delay in transmitting data across a LAN is minimal.
LANs provide greater control and security over network resources
Disadvantages
Limited Geographical Coverage: LANs have a limited geographical coverage area, typically confined to a building or a specific site.
Limited Connectivity: LANs provide limited connectivity beyond the local area.
If the central device fails, it can lead to downtime and loss of connectivity for all connected devices within the LAN
Network is classified based on its coverage area.
Wide Area Network (WAN)
A network that connects computers and devices in a large geographical area such as a city, states, countries, or the world using a communication channel that combines many types of media such as telephone lines, cables and radio waves.
Characteristics of WAN
Area of coverage: The area covered by a WAN is large, usually covering two or more cities, states, countries or continents.
Ownership: WAN owned by multiple/shared/distributed ownership
Cost of setup: Cost of setting up a WAN is higher compared to LAN as it requires more planning, more hardware and leasing long distance transmission lines.
Advantages
Allow wider communications across different cities and countries
Enable efficient data backup and data recovery
WANs can be used to connect devices that use different types of networking protocols
Disadvantages
Lower data transfer speed compared to LANs.
Higher infrastructure and operating costs
Complex network configurations and require skilled IT professionals to design, implement, and manage.
