Understanding The Functions Of A Proxy Server

In a network of computers, an application program or the computer system will function as a server. It acts as a link to get the information required from the other servers by the user of the computer. The client or the user will be connected to the proxy server when he requests for a file or a connection or a web page or any other details that are available from the other server. The request of the client is evaluated by the proxy server based on the rules of filtering.

For example, the proxy server may filter the traffic based on the protocol or the IP address. If the proxy server validates the request according to the filter, then it offers the resource by just connecting it to the concerned server and pass on the request for the service on clients behalf. The proxy server has also got the option to alter the request of the client or the response of the server and in many cases the request is served without any communication to the particular server. Instead, in this circumstance, it caches the reply from the remote server and forwards the further requests direct with regard to the same matter.

The proxy server has got two purposes. One is that it keeps all the computers behind it as anonymous mainly for the purpose of security. The next one is that it speeds up the access to the resource through caching. It is popularly used just for the purpose of caching the web pages from the web server.

The proxy server also passes the replies and the requests without any modification and is generally called as the gate way. It is also otherwise called as the tunneling proxy.

The proxy server can be located in the local computer of the user or even at different points between the source servers and the user or in the internet. The reverse proxy is a type of proxy that is utilized as a front end to speed up and cache the resources in demand like web page.

Although there are various uses that can be obtained from the proxy servers, the most important one is that it reduces the cost of the hardware. A company may be in possession of many computers that are connected on the same network or may be even under the control of one server and thus does not allow all the computers to have the connection to the internet directly. Under these circumstances, each and every computer under the same network can be connected to a single proxy server and in turn the proxy server will connect the computers to the main server for access to the internet.

Surfing the Internet is becoming an essential thing in most of peoples life. Unfortunately, more and more PC users battle with an awfully slow internet speed. The sluggish internet speed will cause much inconvenience to computer users. With the poor speed, you can do nothing but just waste your precious time. Here, I would like to discuss some easy ways to improve internet speed with you guys.

1. Internet Speed Problems caused by Binding too many Agreements on Network Card

Slow internet surfing speed is a usual problem among LAN users because there are too many agreements binding on the Network Card. If a NIC is bound lots of agreements then the computer has to spend more time on identifying which agreement would transmit a certain group of data that passes it. PC users will feel uncomfortable at the moment when they are surfing the Internet. Here is a solution for this situation:

b. Use another one to run other agreements in order to boost its performance so that the speed of internet surfing would be improved obviously.

2. Internet Speed Problems caused by Unbound TCP/IP Agreement.

Unbound TCP (Transport Control Protocol)/IP (international agreement) may be caused by reasons as follow: a. the driver of Network Card is installed incorrectly. b. There is a problem with quality of Network Card. c. PCI slot is broken. Solution for this situation: You should uninstall NIC driver in the Device Manager at first—-reinstall the driver after you reboot your computer. If you still fail to improve the internet speed with this solution, please change a PCI slot for Network Card or change a new one.

3. Internet Speed Problems caused by low quality of telephone line.

If the phone line is affected by some bad extraneous factors, network device will adjust client access rate automatically and dynamically according by the quality of line and transmission distance. The Internet surfing Speed also will be affected by the export bandwidth, the website line from opponents and the device configuration if you try to visit foreign website.

It has an easy concept, hosting an application or we can say application hosting is a web based solution that enables clients to run software applications via cloud on a recurring basis and is generally provided by an ASP i.e, Application Service Provider or Application Hosting Provider.

The requirement for ASPs has evolved from the increasing costs of specialized software that have far surpassed the price range of small to medium sized businesses. As well, the growing complexities of software have led to maximum costs in distributing the software to end-users. With the help of ASPs, the complexities and costs of such software can be cut down. In addition, the problems of upgrading have been eliminated from the end-firm by placing the onus on the ASP to maintain up-to-date services, 24 x 7 technical support, physical and electronic security and in-built support for business continuity and flexible working.

A hosted cloud system can be leased or rented on a monthly or annual basis, thus discarding the need to buy expensive equipments, the main reason is that most of the equipments are hosted by the service provider and all communication is routed through that provider to and from your company’s site or sites. Application hosted environment setup has an advantage in terms of cost of operation, and it is also easier to install, increases the flexibility and allows communicating from any part of the world with just an ease.

Hosted cloud solution is very inexpensive to operate, and as usage and number of user increases, the cost advantage of hosted application systems simply disappears.
