Bandwidth – bandwidth is the bits-per-second (bps) transmission capability of a
communication channel. It also refers to the amount of data that can be transmitted in a fixed
amount of time. There are three types:-
(i) Voice band – bandwidth of standard telephone lines.
(ii) Medium band – bandwidth of special leased lines used.
(iii) Broadband – bandwidth of microwave, satellite coaxial cable and fibre optic.
Interconnectivity costs
These are costs incurred in running a network. These costs basically include the subscribing costs
which run when the network is interacting with other networks. It also includes unquantifiable
costs like security threats.
(ii) Factors that determine the extent to which network performance degrades or
Slows down: -
i) Bandwidth – the size of the bandwidth will determine the speed of network. A
large bandwidth will be sufficient to support a large number of network users
without slowing down the network.
ii) Software - For example, a network operating system with a high performance (eg
linux operating system) can be able to provide a high network performance.
iii) Hardware – different hardware have different capability thus if the hardware is
outdated then the network will slow down.
iv) Dedication of the servers – when a server is connected to different networks
then it will be painfully slow as so many users are using the server. As such
servers should be connected in a way to serve limited networks for optimum
performance.
