The Importance Of Proxy Servers

A proxy server acts as a connector between two networks. One network is the internet and the other network is a series of system that are connected within themselves.

The primary reason for using a proxy server is to hide system identity from other systems on the internet. Internet cafes make use of proxy servers for the purpose of managing payment for internet access. People who are under oppressive regimes make use of proxy servers to spread their political opinions. Using a proxy server also increases the speed of internet access in some cases.

There are many types of proxy servers and you can choose one depending on your requirement. The most basic type of proxy server is the simple proxy server. This is a very basic proxy server type and it receives request from the client computer and sends the request for access to that internet resource. It then returns response from the client back to the internet resource.

Another type of proxy server is the reverse proxy. This proxy server receives requests from various systems connected to the internet and connects it to a group of internet servers.

If the internet connection is slow, a caching proxy server is used. This server saves a copy of all fetched content and used that copy whenever new content has to be fetched. These types of servers are used in fast connection environment for the purpose of saving bandwidth cost.

There is a need for restricting internet access so that content filtering proxy servers enable filtering of content during the process of internet access. This type of server is used by schools to block objectionable sites and in some cases companies to restrict job sites, porn websites and even social networking websites. The network administrator can set those sites that can be viewed and block sites that should be avoided.

Benefits Of Print Server

Print server is basically a computer or device which is connected to one or more printers and to client computers over a network.It can accept print jobs from the client computers and allocate the jobs to the printers.
Print Server Advantages
Benefits of print server are enlisted as:
Print server lowers the administrative and management workload due to centralizing local and remote printer management. It allows prioritization of print jobs. It is known that priorities can be assigned to print jobs such that more important jobs are printed before those less important.

Print server allows an administrator to manage and control access to each printer. There are three level of printer permissions, print, manage documents and manage printer. Print permission allows a user to print documents, pause, resume, start and cancel his documents. This permission is granted to everyone in the group.

Manage documents permission is assigned by administrator to selected users when required. With this permission, user can control job settings for all documents. Manage printer permission allows the user to pause and restart the printer, share a printer, adjust printer permissions, change printer properties and change spooler settings.

With the use of print server, client computer jobs are quickly spooled to print server as compared to printer. The main point is that while printing large jobs from an own printer, user may have to leave his computer running until printing task gets completed. But with the use of print server, if any job has been spooled to it, then user can shutdown his system.

A system administrator can easily manage printers with the print server. If your own printer goes down, then you will not be able to print documents. But with the use of print server, when a printer goes down, then the printing job is transferred to other printer.
Print server manages workload on printers such that if one printer has lots of printing jobs, then it will assign some of the jobs to other printers in the network. It means if your printing job is spooled to print server, then it will get completed.
