yaaa.... single server can manage many clients but if in case any problem occur default member server will helps at that time ... so we must maintain the member server ..
You can't have two domains on the same server 2003 machine, since it has to manage a single domain. However, you can have many domains in a server 2003 forest or a series of trees, which are managed by a forest controller. And, a single server 2003 can manage multiple domains.
Client Server software allows a central, single copy of software to be shared among many users of a network. If this is an operating system, then the software may be responsible for managing the network as well.
In the computer industry, server side refers to the operations performed by a server in a server-client computer relationship. The server side typically handles many functions to lighten the load of the client side's work.
The term client-server is not considered outdated, as the concept is still necessary for many systems to function efficiently.
The client server building blocksThe Client Building BlockRuns the client side of the applicationIt runs on the OS that provides a GUI or an OOUI and that can access distributed services, wherever they may be.The client also runs a component of the Distributed System Management (DSM) element.The Server Building BlockRuns the server side of the applicationThe server application typically runs on top of some shrink-wrapped server software package.The five contending server platforms for creating the next generation of client/server applications are SQL database severs, TP Monitors, groupware servers, Object servers and the Web server.The server side depends on the OS to interface with the middleware building block.The server also runs DSM componentIt may be a simple agent or a shared object database etc.The Middleware Building BlockRuns on both the client and server sides of an applicationThis broken into three categoryTransport StacksNOSService-specific middlewareMiddleware is the nervous system of the client/server infrastructureThis also has the DSM componentDSMRuns on every node in the client/server network.A managing workstation collects information from all its agents on the network and displays it graphically.The managing workstation can also instruct its agents to perform actions on its behalf.Server-to-server MiddlewareServer-to-server interactions are usually client/server in nature - servers are clients to other servers.However, some server-to-server interactions require specialized server middleware. For example, Two-Phase commit protocol may be used to coordinate a transaction that executes on multiple servers.Servers on mail backbone will use special server-to-server middleware for doing store-and-forward type messaging.But most modern software follows the client/server paradigm.The building blocks of client/server applications are:ClientMiddlewareServerThese building blocks can be rearranged to use them in the following situations:1. Client/Server for tiny shops and nomadic tribes - This is a building-block implementation that runs the client, the middleware software, and most of the business services on the same machine. It is the suggested implementation for the one-person shops, home offices, and mobile users with well-endowed laptops.2. Client/Server for small shops and departments - This is the classic Ethernet client/single-server, building block implementation. It is used in small shops, departments, and branch offices. This is the predominant form of client/server today.3. Client/Server for intergalactic enterprises - This is the multiserver building-block implementation of client/server. The servers present a single system image to the client. They can be spread out throughout the enterprise, but they can be made to look like they are part of the local desktop. This implementation meets the initial needs of intergalactic client/server computing.4. Client/Server for a post-scarcity world - This model transforms every machine in the world into both a client and a server. Personal agents on every machine will handle all the negotiations with their peer agents anywhere in the universe. This dream is almost within reach.1) Client/Server for Tiny Shops and Nomadic TribesIt is easy to run the client and server portion of an application on the same machine.Vendors can easily package single-user versions of a client/server application.The business critical client/server application runs on one machine and does some occasional communications with outside servers to exchange data, refresh a database and send or receive mail and faxes. Ex: Internet.2) Client/Server for small shops and departmentsThe client/server architecture is particularly well-suited for the LAN-based single server establishments.It consists of multiple clients talking to a local server.This is the model used in small businesses.The single-server nature of the model tends to keep the middleware simple.The client only needs to look into a configuration file to find its server's name.Security is implemented at the machine level and kept quite simple.The network is usually relatively easy to administer; it's a part-time job for a member of the group.There are no complex interactions between servers, so it is easy to identify failures- they're either on the client or on the local server.3) Client/Server for Intergalactic Enterprises:The client/server enterprise model addresses the needs of establishments with a mix of heterogeneous servers.These models are upwardly scalable.When more processing power is needed for various intergalactic functions, more servers can be added, or the existing server machine can be traded up for the latest generation of superserver machine.The servers can be partitioned based on the function they provide, the resource they control, or the database they own.The servers can be replicated to provide a fault-tolerant service or to boost an application's performance.Multiserver capability, when properly used, can provide an awesome amount of compute power and flexibility, in many cases rivaling that of mainframes.To exploit the full power of multiservers, we need low-cost, high-speed bandwidth and an awesome amount of middleware features -includingnetwork directory servicesnetwork securityremote procedure calls andnetwork time services.Middleware creates a common view of all the services on the network called a single system image.Good software architecture for intergalactic enterprise client/server implementations is all about creating system "ensembles" out of modular building blocks.Intergalactic client/server is the driving force behind middleware standards as distributed objects and the Internet.4) Client/Server for a Post-Scarcity WorldEvery machine is both a client and a full-function server.Because every machine is a full-function server, it will run, at a minimum, a file server, database server, workflow agent, TP Monitor, and Web server - all connected via an ORB.This is in addition to all the client software and middleware.In next few years, a hundred million machines or more may be running almost all the forms of client/server softwareIn this model instead of mobile agents, personal agents will be used.
It depends on how it is used. Software on a server usually has a limit on how many clients can access it at one time.
A personal computer is usually a stand alone computer in the home and is fully functional by itself. A server computer can do many things, usually used in offices, schools and any other establishment with several machines. A servers main existence is to connect other computers around it and proved services. Such as on a network at one of these establishments let say you click print on a word document, this would then be sent to the server and then sent to the printer nearby. I use to work for a University, they had about 70 servers, quite often a server will have one duty such as a web server which simply sends the websites you want to see to your computer. The Internet is made of servers that share data all day.
A client-server computer architecture involves a centralized server that provides resources and services to multiple client computers connected to it. In contrast, time-sharing allows multiple users to access a single computer system simultaneously by dividing the CPU time among them. Client-server systems are typically used in network environments, while time-sharing is commonly seen in mainframe or supercomputer setups. Both architectures have their own advantages and disadvantages in terms of resource allocation, scalability, and security.
Many networking services use a client-server model, where information is centralized at a server. The server will wait for requests from a "client", and once it receives one, it will reply. The functions vary widely, depending on what server you use; you have centralized storage of files, databases (as in "an oracle server"), dynamic assignment of IP addresses (DHCP server), centralized printing (print server), sharing an Internet connection (Proxy server), and many others. "Server" may refer to any of these services, but also to the computer that hosts these services.

The computer requesting information is called a CLIENT. The computer responding to the request is called a SERVER. Data transfer from a client to as server is reffered to as an upload. EX. When you want to enter the game. Ur the client waiting for the server to get you in Data transfer from a server to a client is reffered to as a download. EX. When you download stuff from Limewire or Utorrent. Your the server waiting for the client to give you the song or movie.
