1- Ubuntu is different. Everything is done via repositories and it uses a dedicated update manager to update both the operating system and all of the applications installed. So you only ever have to manage your updates from one place.
2-Ubuntu is also a lot less popular than Windows. That means that the bad guys who make all the viruses don’t really care about it, so they don’t bother writing much malware for Ubuntu: that’s great news for us users!
3-Desktop customization is also cool in Ubuntu there are several themes available over the internet
4-We can also use as a live environment
5-Ubuntu is 100% free. It won’t cost you a penny (although you can make a donation on their download page)

Swap Area ( Linux-swap)
Swap space in Linux is used when the amount of physical memory (RAM) is full. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space. While swap space can help machines with a small amount of RAM, it should not be considered a replacement for more RAM.
For more modern systems (>1GB), your swap space should be at a minimum be equal to your physical memory (RAM) size “if you use hibernation”, otherwise you need a minimum of round(sqrt(RAM)) and a maximum of twice the amount of RAM
Now proceed according to instructions . . .
