 Computer  network consists of communications media, devices and software needed to connect two or more computer systems or devices. The computers and devices on the networks are also called network nodes. After they are connected, the nodes can share data, information, and processing jobs. Increasingly, businesses are linking computers in networks to streamline work processes and allow employees to collaborate on projects. If a company uses networks effectively, it can grow into an agile, powerful, and creative organisation, giving it a long-term competitive advantage. Organisations can use networks to share hardware, programs, and databases. Networks can transmit and receive information to improve organisational effectiveness and efficiency. They enable geographically separated workgroups to share documents and opinions, which fosters teamwork, innovative ideas, and new business strategies (Stair and Reynolds,2014, p.228).

According to (Clements 2006), the most general topology is the unconstrained network. The individual nodes are connected in an arbitrary fashion. Its advantage is that additional links can be provided to reduce bottlenecks where heavy traffic passes between a group of nodes. Further nodes and links can readily be added without disturbing the hardware of the existing system. The star networks route all messages from to destination via one central node and eliminates the need for nodes to make routing decisions. The star has a simple topology and has advantages when the networks physical topology matches its logical topology. The bus and the ring both minimise the complexity by both removing a special purpose central node and the need for individual nodes to make to make routing decisions.
