Network Environment
[Chapter 2]
Network Architecture
Client server network consist of a group of user oriented PC’s [Clients] that issue request to a server a client PC responsible for issuing request for servers function on the network is service this request.
In a client server environment like Windows NT or whole network files are stored on a centralized high speed F.S. PC that is made available to client PC network access speed are usually faster than those found on peer-to-peer network which is reasonable given the vast number of client that this architecture can support. Nearly all network services like printing and email routed through the file server which networking task. In efficient network segments can be reworked to make them faster and user’s activity can be closely monitored. Public data and application are stored on the file server, where they are run from client PC’s location which makes upgrading software a simple task in a network administrators can simply on the file server. Rather than having to physically upgrade each client PC’s.
In the client server diagram the client PC’s are shown to be separate and sub-ordinate to the file are stored in a common location. File server are often setup do that each users on the network has access to his or her on directory, along with rang are stored. If the two clients above want to communicate to each other, they must go through the file server to do it. A massage from one client to another is first send to the file server where it is then routed to its destination whit loads op client PC’s a file server is the only way to manage the often complex operations that large networks required
A peer-to-peer network allows two or more PC’s to pull there resources to gather. Individual resources like disk drives, CD ROM drives, and even printers are transformed in to shared, collective resources that are accessible from every PC. Unlike client server network where network information is stored on a centralized file server PC and made available to 1000end of client PC’s. The information stored across peer-to-peer PC have there own hard disc that are accessible by all computer each PC acts as client and a server. The given diagram 3 peer-to-peer work stations are shown. All through not capable of handling the same amount that a client server network might the entire computer can connect with each other and shares another resource.
