Many Linux operating systems come in live CD’s. Many of these Operating systems are quite useful since they come packed with a lot of good utilities like word-processing, Powerful browsers. Hence through Live CD’s these operating systems can be booted without installing them in the hard-disk in the first place.

What is the use of a USB HUB?
