The proxy a server is an intermediate computer, which is the intermediary ("proxy" - the intermediary) between your computer and the Internet. Through him pass all your manipulations in Internet. Proxy them processes, and results transfers you.
The Proxy-server is various. He is capable:

• To accelerate your work with Internet;

• To make your anonymous travel on the Network;

• To allow to enter into chats even if you have blocked;

• To help to look those sites to which has closed access your system administrator;

• And many other things.

You can ask " What for to me it is necessary to a proxy?? To me and so it is good ". Really, since the childhood we know, that the shortest distance between two points - a straight line :-) But cunning consists, that we require not the shortest distance. The best speed of communication is necessary to us. And high speed not necessarily is consequence of the shortest distance.

Imagine a following situation: you live in city "A", and wish to get in far city "B" (or to you wish to arrive from this city). You can take advantage of usual transport - bus or the railway. But to go such transport up to destination very long. And if you by means of the bus will reach other city - "C" where there is an airport by plane reach much more quickly your destination (cities "B"). And the city "C" can be further away from "B", than your city "A".

The simple scheme:
"A">>>> (train)>>>> "B"
It turns out longer, than
"A">>> (train)>>> "C">>> (plane)>>>> "B"

The similar scheme is used and here: you incorporate to a proxy-server (train from "A" in "C"), and the proxy a server, using the allocated line or an optical fiber ("plane"), transmits or obtains data from a web-server (from "C" in "B").

Communication without a proxy is realized under the following scheme:
Your computer>>>> web-sites
At use of a proxy-server the scheme is represented so:
Your computer>>>> proxy>>>> web-sites
