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.

Do Bar And Ring Magnets Have Different Magnetic Properties Science Fair Project

Magnets are a common test subject for elementary and middle school science fair projects. Magnet science fair projects often examine what impacts a magnetic field or what a magnetic field can impact. In this sample project students will be examining if magnetic properties can be manipulated based on the type of magnet, ring or bar, that is used.

Hypothesis

The hypothesis for this science fair project is that the ring and bar magnets have the same magnetic properties. The dependent variable for this hypothesis is the type of magnetic properties that are displayed by the magnet and the independent variable is the type of magnet. To clarify this hypothesis the term magnetic properties needs to be defined as having a magnetic polarity.

Supplies

To complete this magnet science fair project students will need a variety of bar and ring magnets. They will also need to have objects that also have polarity such as metal objects. Finally, students will need a data collection sheet.

The Experiment

The control experiment for this test will use the bar magnet. This magnet was chosen because it has the most traditional shape and properties. It will serve as the baseline data source. To test the magnetic properties of a bar magnet students will need to test the bar for polarity by identifying if it attracts opposite poles and if it repels like poles.

The test experiment will focus on the ring magnet. This magnet will be run through similar tests. A bar magnet that has poles clearly labeled can be used to test the polarity of various points on the ring magnet. Students will want to mark what areas of the ring magnet are attracted by each pole of the bar magnet and which areas are repelled.

Data Collection and Analysis

The collection of data will be based on simple observations of repulsion and attraction trends for both the bar and the ring magnets. The analysis of the data will revolve on the students ability or inability to find poles on the ring magnet. (*Hint: the poles on a ring magnet may not be found on the curved edge of the magnet.)

In order to prove the hypothesis may be correct the student will need to find polarity properties on the ring magnet. If polarity is not found then the hypothesis can be assumed to be false. Students may need to run this experiment several times to gather enough data to make a solid conclusion from the data that they collect.
