Star
A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub or concentrator (See fig. 2).
Data on a star network passes through the hub or concentrator before continuing to its destination. The hub or concentrator manages and controls all functions of the network. It also acts as a repeater for the data flow. This configuration is common with twisted pair cable; however, it can also be used with coaxial cable or fiber optic cable.

Tree
A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable (See fig. 4). Tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs.

Linear Bus
A linear bus topology consists of a main run of cable with a terminator at each end (See fig. 1). All nodes (file server, workstations, and peripherals) are connected to the linear cable. Ethernet and LocalTalk networks use a linear bus topology.

Wired/Wireless Networking
A local area network (LAN) will allow peripherals, documents, databases, and the internet to be shared by multiple computers. Whether you require a client-server or peer-to-peer configuration, we can easily ascertain your needs and construct the appropriate wired or wireless network solution.



Sharing the internet, printers, scanners, back-up media, and other resources is always a far better option than purchasing duplicate equipment for each workstation your organisation might own. But to do so, a local area network needs to be in place.

Besides sharing hardware it is likely you will need to share vital data among colleagues or departments within your organisation. For example you may have a database application which records contacts information but sadly its only available on your workstation. Imagine the benefit to your organisation if more than one person could query the database directly. Workload would be reduced, savings could be made on printed media, and information could be accessed expediently . A centralised database system will always allow your organisation to function efficiently.

Whether you require a client-server or peer-to-peer configuration, we can easily ascertain your needs and construct the appropriate wired or wireless network solution. We can offer a range of networking solutions using wired or wireless technology which includes:

Discussing your networking requirements.
Providing a wired or wireless solution.
Building a peer-to-peer or client-server configuration.
Sharing your ADSL or Cable broadband connection.
Installing and configuring LAN adapters on each workstation.
Installing Cat5e structured cabling including RJ45 ports.
Installing ethernet hub, routers, and access points
Patch cable construction.
