In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it would 'cache' the first request to the remote server, so it could save the information for later, and make everything as fast as possible. A proxy server that passes all requests and replies unmodified is usually called a gateway or sometimes tunneling proxy. A proxy server can be placed in the user's local computer or at specific key points between the user and the destination servers or the Internet.

Protect our belonging

GPS tracking if I heard that words I always remember about one of my favorite film, the title is “Enemy of the state” maybe you all already watch this movie and so many question will come up, we feel that the personal live will no longer belong to us, every single movement always still can be track.

Understand that GPS tracking will help us to track our belonging or to track our family, our pets or anything that we need to know. Now days this technology already used worldwide since it was found and really help for mankind. Although so many pro contra with this stuff, but still mostly said that this is a wonderful tools that can help the world with all their consequent

If we talk about GPS tracking 4 year ago it seems that this is the high end stuff and only limited off people that really need this, military the one that always using this stuff, they can put at car, airplane, etc. Also it can track people without realizing it, for me this kind of stuff we need it as long as we used it as in good purposed.
