Model of Topology

 
Bus Topology, Client/Server Network, LAN Network


We use bus topology in the post office because it is inexpensive and easier for us to install. If we adding or removing a node such as a personal computer from the backbone, it does not affect the rest of the network in the post office.And if there is a failure of one node in the network, it also does not affect the rest of the network.

We use Client/Server Network in the post office because the network can works in any size and does not tend to slow down if there are more nodes are uses in the post office. the security of the Client/Server Network also more advance than Peer to Peer Network because we can use our personal profile by using a password to access so the others cannot access our computer because of the passwords that we used in the computers.

We use LAN Network in the post office. This is because LAN Network is a network that connects computers and devices in a limited geographical area. So, LAN Network is suitable use in the post office building. The network that we use are owned and operated by an organization in the post office building. The communications devices that we use is switch or hub to connect multiple devices on a single wireless network such as Wi-Fi range in the post office. This is because we can share the information, data, hardware and software for lower cost and it also can saves our money on hardware expenses.
