Skype is a freeware (limited) Application that is used in Instant messaging, voice calls (VoIP,Voice over Internet Protocol) and video conferencing. You can also call to mobile or landline telephones with some charges (Debit type). Skype (originally called as : sky peer-to-peer) is one of the most popular apps for video calling.
Skype is different from other VoIP software, due to its architecture, other VoIP software are based on client server system (e.g Google Talk) while Skype uses peer to peer system (probably that’s the reason why Skype consumes a lot of bandwidth in comparison to other VoIP application). On Ubuntu 11.04 (Natty Narwhal), empathy is installed by default, but it’s video/audio quality is very poor, skype is better than that. This article will explain you – how to install skype (Latest beta version : 2.2) on a freshly installed Ubuntu 11.04. Since Skype is a proprietary application, you can’t find it in Ubuntu Software center or Synaptic Package Manager, so it can be installed after downloading the package (Debian Package, with extension .deb).

swap memory space and swapping in OS
Swapping is a simple memory/process management technique used by the operating system(os) to increase the utilization of the processor by moving some blocked process from the main memory to the secondary memory(hard disk);thus forming a queue of temporarily suspended process and the execution continues with the newly arrived process.After performing the swapping process,the operating system has two options in selecting a process for execution :
*Operating System can admit newly created process (OR) *operating system can activate suspended process from the swap memory.
Conclusion : If you have ever used any Linux based operating system then at the time of installation …Did you see an options/warning for the need of swap memory space?? If you have enough primary memory(RAM) e.g greater than 2GB then you may need not any swapping memory space for desktop users(I am using Ubuntu 10.04 LTS and total RAM is 4GB so I am not feeling any trouble without swap memory space) and some times using swap memory may slow down your computer performance.
