Practical Networking

A detailed Summary of Practical Networking


Every branch, including the Head Office in Johannesburg, will need to have a DHCP V Dynamic Host Configuration Protocol Server. This enables for IP addresses in that particular network to be assigned dynamically to all networked computers. This protocol brings with the advantages of:

„« Assigning valid IP addresses i.e. those that are appropriate for the type of network type concerned and especially the subnet mask that the system is on.

„« Reducing the chances of getting redundant IP addresses leading to errors and conflicts.

„« Automatically reconfiguring the IP addresses of workstations that were moved to another segment of the network.

„« Saving a network administrator considerable time and expense.

The Proxy or Internet Server that is connected to the PDC in the head office has to run the Hypertext Transfer Protocol. This allows a Web Server to be connected to Web Browsers. For this reason all the computers in any domain of any branch that requires Internet access also need to run this protocol. It creates a link between the workstation of the user and any document he/she is trying to reach.

This server also needs to run an SMTP V Simple Mail Transfer Protocol. As its name suggests, this protocol allows for th


Routers should be installed in every one of the branches to facilitate transmission processes inside the WAN V wide area network V that exists between the branches. This in turn could allow for utilities such as Distance Vector and Tracert to increase the speed and performance in data transfer.

Because a router determines what data goes where it can be used as a firewall. This means that it will monitor dataflow i.e. from where to where, and access could therefore be denied.

„« Messages can be stored hierarchically on a server

„« It allows mail to be downloaded selectively
