INTRODUCTION TO "PEER TO PEER FILE SHARING" (P2P file sharing)

Peer to Peer file sharing has become one of the most popular way of sharing different contents like movies, songs ,softwares etc. on Internet. Many people don't even realize they are using P2P file sharing while downloading files using limewire or torrent client.

When we download something from a file sharing website or any other website we actually download the file from the website's server using the FTP protocol (FTP protocol are set of standard rules for file transfer) , now the servers have a bandwidth limit means there is a limit to the downloading speed, due to this the download speed can't go beyond a specific limit. This is called client server sharing. Downloading from popular sites can be fast, but there is always a limit.

Now lets take a look at P2P file sharing.Unlike centralized client-server sharing model P2P uses P2P networking for sharing contents. In P2P networking the users are directly connected to each other without any interference from any servers. Means the traffic does not pass through any servers. The users are called pears. All these peers are mostly equally privileged and act both as a client and server (consumer and supplier).

FREE SOFTWARES TO SPEED UP COMPUTER

Now-a-days computers have large amount of RAM, so they are usually fast enough. But many users still use old computer or have less RAM. These computers can be very slow and irritating .There are many reasons for slowing down of computers like

• Virus and worms
• The files are not organized properly.
• Uninstalled or broken uninstallable applications.
• Registry problems.
• Too many duplicate files. etc

Most of these problems can be easily corrected using free and open source softwares. Here are some of them

DEFRAGMENTING COMPUTER

Many of the PC users must have observed that as the hard-drive starts filling up, the computer starts slowing down. One of the main reason for this slowing down is Fragmentation of the File system. This problem can be easily corrected by Defragmentation. But before that let us have a look at what really is Fragmentation of file system.

Fragmentation
When the hard-drive is new the computer stores the files in continuous manner. But after some time gaps start forming between files (this gaps form due to deletion of old files or when the computer allocates excess space for the file.) As the hard-drive fills up the computer starts storing fragments of the files in this gaps. This greatly reduces system performance.


Defragmentation
The above problem can easily corrected by defragmentation. defragmentation reorganizes the files contiguously and closer to each other. This creates larger areas of free space which prevents from further fragmentation. Windows has a internal defragmenter but it is not highly efficient and it uses high amount of system resources thus affecting other system processes. Here are 2 of the best free defregmenters out there
