Linux is the operating system for a GNU generation and is considered to be an alternative to Microsoft. Linux is a free operating system that looks and acts very much like UNIX. It can be downloaded off the net for free or can be copied legally.
Alternatively, Linux can be purchased from an internet store, along with a book about it. Linux is a complicated operating system and depends upon the utility. For basic operations and simple rudimentary things, windows would be enough but for the user who is a pioneer and wants to find more about the system and perform the maximum, Linux is worth trying.
Linux is perfectly suited to students, developers and those who are above the normal. It needs powerful processes and hardware whose most important component is the memory. If the Linux memory is of 512 MB and 20gig hardware, then it would be sufficient.
This kind of memory would help to run all the applications including the websites with ease. But there should be a permanent connection to the internet, if one wants to host his or her own websites. Since almost all the virus writers have Microsoft windows as the only target in their mind, most of the time, it is not needed to have any anti virus or anti spy ware software while running Linux. Usually, Linux works well even on a system with only 4 MB of RAM.
