The central feature of client/server architecture is the allocation of application tasks between clients and server. In both client and server the basic software is an operating system running on the hardware platform. The platforms and the operating systems of client and server may differ.
There may be a number of different types of client platform and operating systems and a number of different types of server platforms and operating systems in a single environment. As long as a particular client and server share the same communications protocols and support the same applications, these lower-level differences are irrelevant.
It is the communications software that enables client and server to interoperate. TCP/IP, OSI are some examples of communications software. The point of all of this support software (communication and operating systems) is to provide a base for distributed applications. Ideally, the actual functions performed by the application can be split up between client and server in a way that optimizes platform and network resources and that optimizes the ability of users to perform various tasks and to cooperate with one another in using shared resources. These requirements dictate that the bulk of the applications software executes at the server, whereas most of the application logic is located at the client in other cases.
An essential factor in the success of a client/server environment is Continue reading »
Website hosting is the only thing which connects the website with the internet and let the website accessed from anywhere in the world. Server is the first and pre required thing for hosting the website and the service of the website rely on the quality of the server. If you want to host an ecommerce website, then the designated server may serve the main purposes of the website and also will ensure the best security.
Dedicated server is one of the useful conception for hosting the ecommerce and large websites. Nearly all the hosting companies create their accounts on the specific shared server. A single hard drive and memory device may be used for hosting n number of websites and the bandwidth also may be divided among the sites. It is always suggested to arrange a single hard drive for storing your single site data. You must get the promoted bandwidth and the security with best. A dedicated server maybe defined as the single server for storing a single website and no other sites will be hosted in that machine. Dedicated serve guarantees better security and flexible bandwidth.
Dedicated server is having some features those are very much required and important for the website in different purposes. The most important features of dedicated server are server security, data transfer, space, software facility and control panel are some of . For having those features, mostly all the clients choose dedicated server as the best server.

There is no denying the fact that the server is a multi-user computer where there is no unusual hardware prerequisite that turns a computer into a server and as such the hardware platform needs to be preferred based on application demands and financial stringency. Servers for client/server applications work unsurpassed when they are configured with an operating system that supports shared memory, application isolation, and preemptive multitasking. An operating system with preemptive multitasking enables a higher priority task to preempt or take control of the processor from a currently executing, lower priority task. The server provides and controls shared access to server resources. Applications on a server must be isolated from each other so that an error in one cannot damage another. Preemptive multitasking ensures that no single task can take over all the resources of the server and thwart other tasks from providing service. There must be a means of defining the relative priority of the tasks on the server. These requirements are specific to the client/server accomplishment and not to the file server implementation. Because file servers execute only the single task of file service, they can operate in a more limited operating background without the need for application isolation and anticipatory multitasking.
The conventional minicomputer and mainframe hosts have acted as de facto enterprise servers for the network of terminals they support. B Continue reading »
