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.

Web Hosting Service

Everyone knows the Internet. Adult, Elder, Kids, Teenage, and everyone using internet to find information and knowledge for daily purposes. Some might say that Internet has a great wisdom. But do you know about the process…? About the internet? Or even about web hosting service?

First of all, a website needs webhosting service to store files and programming language. So webhosting is a vital for a webmaster. A webhosting service provides a service that allows webmaster to store web pages. Many webhosting providers sell or giving a free service, they provide the technology and servers to view and store website on the internet. They store website (also called web pages) on a dedicated computer called a server. The server is a small part of a huge network of computers on the World Wide Web that allows internet users from around the world to access your site at anywhere and anytime. The internet is never sleep, 24 hours a day, seven days a week and you’ve got the idea.

Most hosting companies require that you buy your own domain name before purchasing hosting service. But worry not because many webhosting providers also includes free domain on their packages. You can buy the domain name and hosting at the same time. Internet is easy, if you know how to use it. Host computers are configured so that when your URL or domain name is typed in, the address will use a pointer routine (look for the address from terminal to terminal) until it reaches the computer that hosts your web-site. Then, if all is okay, your web site should display itself on the users screen.

Next, let’s talk about the domain name. A domain is a unique name that identifies IP addresses on the World Internet. For example, the domain name Google.com represents about 15 IP address. If you are planning to use a web hosting provider service, you can always check on webmaster customer review to help you decide on which one you will use.
Happy playing Internet.

Although the answer was not really satisfied me still I try to asked the brochure and manufacturer description and I decide not to buy the camera right away.

Back to my house and comparing all the detail information that I got still not really understand and I am still not yet decide whether want to buy Canon which has a good image quality, or Nikon which is the seller said “natural color” or just to buy Sony which I had no information clearly about this. Well still confusing me …..or maybe you just need to browse here, so hopefully your decision will not wrong.
