Advantage of network
Provides centralized data storage provides faster data is used for efficient communication between workgroups by using:
1. Electronic mail
2. Online conferencing
3. Group War
Types of networks
On the basis of the area covered, networks are classified into:
1. Local Area Network (LAN)
2. Metropolitan Area Network (MAN)
3. Wide Area Network (WAN)
Local Area Network
1. LAN is confined a single location
2. Uses cables as its connecting media
3. Has the maximum distance between networks limited by:
– The length of the signal
– The network system`s built-in time limit for sending and receiving the messages via the connecting media
Metropolitan Area Network
1. Man covers a larger area compared to LAN
2. Uses the LAN technology
3. Carries information on the from of computer signals
Wide Area Network
1. WAN covers a larger area compared to LAN
2. Carries information in the from of signals from one computer to another
3. WAN is spread over wide areas such as:
– Cities
– States
– Countries
Establishes communication via:
– Telephones line
– Satellites
– Microwaves
Advantages of LAN over WAN
1. LAN designers can setup their own network that is technically reliable
2. Whereas WAN designer are forced to use existing public telephone network that is technically unreliable
3. LAN cables are more reliable since the error rates are lesser than in WAN
4. Error detection and correction are done at lower on LANs as compared to WANs
