2.3 Classification of Network
LOCAL AREA NETWORK (LAN)
Advantages
a) LAN provides faster data transfer rates compared to WANs.
b) LANs have lower latency compared to WANs. With shorter distances between devices the delay in transmitting data across a LAN is minimal
c) LANs provide greater control and security over network resources.
Disadvantages
Disadvantages
a) Limited Geographical Coverage: LANs have a limited geographical coverage area, typically confined to a building or a specific site.
b) Limited Connectivity: LANs provide limited connectivity beyond the local
area.
c) If the central device fails, it can lead to downtime and loss of connectivity for all connected devices within the LAN.
LAN
• What is Local Area Network (LAN)?
» Local Area Network is 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 organizations
Characteristic
• Characteristics of LAN:
(a) Areas of coverage
» It covers limited geographically area.
(b) Ownership:
» LANs owns by single ownership
(c) Cost of setup:
» The cost of setting up a LAN is usually low as compared to a WAN as it is located over a smaller geographic area and does not require additional devices.
WIDE AREA NETWORK (WAN)
WAN
What is Wide Area Network (WAN)?
, A network that covers a large geographic area such as a oity, states, countries, or the world using a communications channel that combines many types of media such as telephone lines, cables, and radio waves.
CHARACTERISTIC
Areas of coverage
The area covered by a WAN is large, usually covering two or more cities, states, countries or continents.
» Ownership:
WAN owns by multiple/shared/distributed ownership.
» Cost of setup:
Cost of setting up a WAN is higher compared to a LAN as it requires more planning, more hardware and leasing long distance transmission lines
Advatanges
a) Allow wider communication across different cities and countries.
b) enable efficient data backup and disaster recovery.
b) Higher infrastructure and operating
c) WANs can be used to connect devices that use different types of networking protocols.
Disadvatanges
Lower data transfer speeds compared to LANS.
b) Higher infrastructure and operating
costs
Complex network configurations and require skilled IT professionals to design, implement, and manage.
