House, i want to know the features of vpn, how does it work? Can it be used with a gprs service? Can it be used for free browsing?Which are the reliable companies that offers such service? How excellent is the service. Lets put heads together and answer these questions thanks.

means wat its means. in simple english, artificial private network, its an environment created within your normal computer envioronment. a more private one i might add. think of it this way, normally, when you browse the web, u use programs like I.E7 or firefox or opera. these are commonly used browsers but what if you browse the web anoynimously without be traced or anything.
this is the whole ideal. it is more secure with a lot of security features. can it be used with a gprs system?? technically Yes. this means that you will be connected to a server and yu can use yur gprs system to connect remotely to that server so that yu can browse yur files etc. free browsing?? nooooooooooooo. will have to have some contract with an ISP. oh least i forget, you can also configure VPN with your phone lines. i knw that linkserve provides such services, problem is i dont know how reliable they are. hope this answers your question.

Thanks men for the info, i need more comments

as far as i know, vpn stands for virtual private network. sometimetimes refered to as intranet.
i.e exchange of datas and information between computers that are far from one another using the TCP/IP protocol without being connected to the outside internet. Banks uses it. There is a central server(database) at the HQ, and other branches of the bank connects to it using the ip protocol.
