Contributor s : John Sullivan Share this item with your network: Client-server is a relationship in which one program the client requests a service or resource from another program the server. At the turn of the last century, the label client-server was used to distinguish distributed computing by personal computers PCs from the monolithic, centralized computing model used by mainframes.

An Introduction to Client Server Computing

Today, computer transactions in which the server fulfills a request made by a client are very common and the client-server model has become one of the central ideas of network computing. In this context, the client establishes a connection to the server over a local area network LAN or wide-area network WAN , such as the Internet. Once the server has fulfilled the client's request, the connection is terminated.

Because multiple client programs share the services of the same server program, a special server called a daemon may be activated just to await client requests. In the early days of the internet, the majority of network traffic was between remote clients requesting web content and the data center servers that provided the content.

This traffic pattern is referred to as north-south traffic. Today, with the maturity of virtualization and cloud computing, network traffic is more likely to be server-to-server, a pattern known as east-west traffic.

Do you see anything replacing the client/server model in the enterprise in the near future?

This, in turn, has changed administrator focus from a centralized security model designed to protect the network perimeter to a decentralized security model that focuses more on controlling individual user access to services and data, and auditing their behavior to ensure compliance with policies and regulations. Advantages and disadvantages of the client-server model An important advantage of the client-server model is that its centralized architecture helps make it easier to protect data with access controls that are enforced by security policies.

The client sends a request to the server and the server responds with the desired information. The client and server should follow a common communication protocol so they can easily interact with each other.

All the communication protocols are available at the application layer. A server can only accommodate a limited number of client requests at a time. So it uses a system based to priority to respond to the requests.

Denial of Service attacks hindera servers ability to respond to authentic client requests by inundating it with false requests. An example of a client server computing system is a web server. It returns the web pages to the clients that requested them. Difference between Client Server Computing and Peer to Peer Computing The major differences between client server computing and peer to peer computing are as follows: In client server computing, a server is a central node that services many client nodes.

On the other hand, in a peer to peer system, the nodes collectively use their resources and communicate with each other. In client server computing the server is the one that communicates with the other nodes. In peer to peer to computing, all the nodes are equal and share data with each other directly.

Client Server computing is believed to be a subcategory of the peer to peer computing. Advantages of Client Server Computing The different advantages of client server computing are: All the required data is concentrated in a single place i.An important disadvantage of the client-server model is that if too many clients simultaneously request data from the server, it may get overloaded.

An example of a client server computing system is a web server. Maximum capture of information relating to the business and its customers must occur within every business process. Three-tier and N-tier notations are similar, although N-tier architecture provides finer-grained layers.
