What Is Actual Working Of Proxy Server

The most common and popular way to stay on internet nameless is proxy server. To accept incoming request of web and forward it to destination are done by the proxy server machine; these severs acts like a middle men of internet which assist to distinguish your computer and destination server. Each computer get connected to net through proxy server or it is a computer that offers online as well as offline services to permit other system users to use web world. So proxy server serve the role of agent between the client (users computer) and server.
Please dont mix up the concept of a proxy server with a NAT (Network Address Translation). Although they look alike, a proxy server does the work of connection, response, and receives traffic from the Internet. In other words, it acts in support of the client computer. A NAT, on the other side, it changes the original address of traffic coming through it and passes it to the Internet. The computer after the NAT, not the NAT itself, does the work.

Technically the difference between proxy server and NAT is as proxy server use transport level 4 or higher, but NAT using 3rd level.
How It Works:
1.When a user on intranet requested for any web page. Actually it requests to proxy server, which forward it to destination server. It also receive data from net server before the client pc, and it transmits the data to user.
2.Proxy servers maintain log report of total network usage such as download, IP address of accessed websites, date & time of access, URL. E.g. Telnet proxy server can trace each and every data passing through.
3.Some proxy servers have to work with unique users. Many people use Netscape with proxy servers. When such type of software is used, that software must be configured to use it with proxy server. Then only intranet users allow using client software as usual.
4.Proxy server not only work as relay but also it can make secured network in office, home. E.g. a FTP proxy server can configured to restrict any type of miss use, means ban download or upload or both.
5.Proxy server also served as time saver. It keeps the copies of web pages .So when user request for same, proxy server provide that page without contacting to internet server. It save time when time is main factor of work.

The Truth About Internet Connection Speed

Internet connection meters are designed to check the actual speed of your online connection. They work by downloading a data file on to your computer, while measuring the transfer rate. You can then compare the results to the speed claimed by your provider, as well as the averages for your location and type of connection.

Next generation meters can now also permanently monitor your bandwidth usage and record traffic information as it happens. There are some that can even measure exactly how much of your money is being spent on bandwidth. This is the reason why an internet connection meter can be very useful when constructing and locating a host for your business website.

Choosing the right service provider is hard and made all the more challenging by companies hyping up their bandwidth speeds and misleading their prospects. Much of the time, internet service providers use clevely worded statements to create the impression that your line will be the fastest available when it isn’t always the case.

Connection speed testing allows you to figure out if you’re getting good value for money from your ISP and if their connection speed promises are being delivered. There is something to be said about a fast internet connection and how that affects Internet marketing. If a website is well designed and optimised, and runs from a fast server, it should load within 3 to 5 seconds.

A heavy website with a slow connection speed from your server will take a while to load and may discourage visitors from staying on your site. Use a good internet connection meter to test the speed of your website and find out if your site is performing at its best.

It’s also worth noting that Google recently announced that page speed is now a factor in how they rank websites in their listing

An internet connection meter like Net Meter Pro or Speed Meter Pro can help you discover if you’re getting the bandwidth you pay for or if your ISP is overcharging you. If the rumours of ISPs introducing bandwidth caps prove true, then this will make it even more vital that you have a fast, optimized website that can be found quickly, and viewed within seconds.

Look for a comprehensive internet connection meter to gauge the real speeds your connection is giving you. If you discover that you are being short-changed, it’s time to look for a new ISP. Try to find a service provider who can offer you what they promise and don’t limit your websites on page count, or have other hidden restrictions you don’t know about. The rest is up to you.
