Implementing and maintaining a network is an expensive option.

A group of disconnected stand-alone computers are a much cheaper option than a network with the same number of workstations.

Apart from the cost of connecting the work stations to the servers by cable, optical fibre, wireless access points or other means, there are a number of networking hardware devices that make a network an efficient option. Hardware devices such as routers, hubs, switches and a variety of servers are often the backbone of any network.

The implementation cost of these devices can be expensive but so is the cost of repairs or replacement when these malfunction.

Many large organisations prefer to employ in-house network technicians that ensure that the network is running efficiently and that any downtime is kept to a minimum. Smaller organisations may employ outsourced technicians to fix their problems. Both of these options can be costly to an organisation.
