BANDWIDTH available for communications between interconnected devices is the main thing that characterises a network.
Internet Cloud refers to all computers, servers & other devices connected together constituting a vast network known as Internet.While Bandwidth is the rate of transmission of bits in a medium to access network. This is generally limited by Devices or by Service Providers.

Many devices were historically available for ISA slots. Modems, sound cards, video cards, hard disk controllers, terminal emulators, and network interfaces are all examples of devices that were available for the ISA slot.
Four computers and two phone devices can be connected with that.
bandwidth is a term used to describe the speed at which data can travel between two systems or devices. It is commonly used when talking about a connection to the internet or business network. Its a slightly-ambigious way of either stating network potential or size of files that would be transferred (a lot of bandwidth, faster downloads or higher data content then low bandwidth)

For internet connections and bandwidth monitoring, I would recommend "WFilter". For local network devices monitoring, I would recommend "spiceworks".
