- 1NetworkIs a method of connecting all the computers together.
- 2LANLocal area network.(same building)
- 3WANWide area network.(Different building )
- 4WLANWireless local area network.
- 5Peer to PeerWhen you connect two computers together.
- 6Client-Server Network.Con be managed centrally from the sever.(Back up.security and access right from one place)Ad:can save a great deal of time.
Dis:If the sever goes down then no-one can access anything. - 7TopologyMethod of joining computers together.
- 8BUS networkCentral way of sending data.Only one device can access the bus at a time.There are terminators at each end of the bus network meaning it can be extended.
- 9ADD/DisAdvantages:
#Easy to install
#Easy to add extra workstations
#Uses less cable than a Star network
#Best choice for temporary networks
Disadvantages:
#If there is a problem with the central cable, the entire network stops working
#If there are a lot of workstations on the network, data can travel slowly.
#Data collisions can happen as the network becomes busy
#Low security - every workstation can see all of the data in the network
#Limited cable length and a maximum number of workstations - 10Ring networkA Ring has no central host computer and noon of the nodes need to have overall control of access to the network.(All computers are joined together where imaginary token is continuously passed around the ring.Token contain which pass around the ring until the data meets it location .
- 11ADD/DISAdvantages:
#Transmission of data is fairly simple as it only travels in one direction #No data collisions
#Extra computers can be added easily with little effect on performance - although you have to shut down the network to be able to do this.
Disadvantages:
#If a single machine is switched off, the network doesn't work
#If a cable breaks, the network doesn't work
#Data must pass through every computer until it reaches its destination. This can make it slower than other network layouts.
#If there are any problems with the network, they can be difficult to identify the cause. - 12Star networkIn a star network layout, each workstation is connected by its own cable directly to the server. Star networks are usually the layout of choice in schools and offices because they tend to be the most reliable of the topological.
- 13ADD/DISAdvantages:
#Star networks are very reliable. If one connection fails, it does not affect other users
#Very few data collisions as each workstation has its own cable to the server
#Good security - no workstation can interact with another without going through the server first
Disadvantages:
#The most expensive network layout to install because of the amount of cables needed
#Installing the network usually needs experts to set it up
#Extra hardware such as hubs and switches may be needed
#If the server crashes or stops working then nobody will be able to access their files or use the network.
