ADVANTAGES OF LAN
Network in an organisation can be a LAN
Typically owned, controlled, and managed by a single person or organization
LANs have a high data transfer rate
Have a small geographical range and do not need any leased telecommunication lines
one LAN can be connected to other LANs over any distance via telephone lines and radio waves
Easy to share devices (printers, scanners, external drives)
DISADVANTAGES OF LAN
device become another point of entry for undesireables.
Upkeep - when things go wrong or the software gets updated.
A lot of times a network shares one Internet connection - if all computers running at once, can reduce speed for each.
ADVANTAGES OF WAN
WAN (Wide Area Network) is a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries
Internet is the best example of a WAN
WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management
WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances
Have a large geographical range generally spreading across boundaries and need leased telecommunication lines
Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites
DISADVANTAGES OF WAN
A WAN is generally slow. If we compare that to a LAN, we said that Ethernet could run up to 1000 Mbps, currently, certainly in South Africa, the fastest WAN is 155 Mbps, so you can see in a LAN we can talk up to 1000 Mbps whereas in a WAN, at the moment, currently,
WAN is expensive. If we look at the path of telecommunications, we need to connect two offices, one in Pretoria and one in Johannesburg together - it 's an expensive operation even for a slow line.
WANs have a lower data...
