2.2 Types of Networks
Understanding Network Fundamentals
What is a company's IT department?
What do they do?
Why are they vital to a company's success?
Take a look at this article and select the 3 most important thing a successful IT department does. Be prepared to explain your answer.
Networks
TYPES OF NETWORKS
The IT Department controls your companies network and there are three types:
1.Covers a small region of space, typically a single building.
2. LAN is the smallest network compared to other two networks.
3. the simplest form of LAN is to connect two computers together
4. LAN is operated within a limited physical area such as at home, school, a single building or several buildings.
5. A network which consists of less than 500 interconnected devices across several buildings, is still recognised as a LAN.
6. LAN is very high speed network (from previously 10Mbps) to 100Mbps,which is faster than MAN and WAN.
Provide a few examples of a company that may have a LAN in the Frederick Area.
LAN: Local Area Network
Do you think you have a LAN in your house?
LAN: Local Area Network
1. Is collection of LANs with the same geographical area, for instance a city.
2. Is a network of computers located at different sites within a large physical area, such as a city.
3. MAN often acts as a high speed network(although not as fast as LAN) to allow sharing of regional resources.
4. MAN can defined as a group of computers and network devices connected together within a large physical area.
5. Companies that have several locations within a City may have an MAN.
Provide a few examples of a company that may have a MAN in the Frederick Area.
MAN: Metropolitan Area Network
MAN: Metropolitan Area Network
MAN: Metropolitan Area Network
1. Is the largest network of all network types.
2. The internet is the largest WAN in the world.
3. WAN generally covers large distances such as states, countries or continents.
4. WAN is group of MANs or LANs or the mixture of both network.
5. An example in the society using WAN is the banking organization.
