Most organization today are moving to client server architectures. Client server attempt to balance the processing between the client and the server by having both do some of the logic. In these networks, the client is responsible for the presentation logic, while the server is responsible for the data access logic and data storage. The application logic may reside on the client on the client or on the server, or it may be split between both. These are many ways in which the application logic can be partitioned between the client and the server. The type of the client server consists of two-tier, three-tier and multi-tier client server. Two-tier client server is one of the most common. In this case, the server is responsible for the data and the client is responsible for the application and presentation. The two-tier client server is uses only two sets of computers, one client and one server. For example, the database management system (DBMS) runs in the server. A request from the client is sent to the DBMS, which responds by searching the server and sending only the result to the client. If 100 records matched the criteria in our million-record example, only 100 kilobytes of data traverse network rather than one gigabyte. Another type of client server architectures is three-tier client server uses three sets of computers. In this case, the software on the client computer is responsible for presentation logic, an application server is responsible for the application logic, and a separate database server is responsible for the data access logic and data storage. Three-tier client server Beside that, the web really is a client server. Because on the server side, the web uses a multi-tier architecture with interlinked web server, application servers, database servers and caching servers. On the client side, user machines commonly execute scripts embedded in countless web pages. They also execute java applets, java programs and rich client application, all of which means that both client and server cooperate in tandem. Advantages and disadvantages of these method The client server architecture does not propose any new model or architecture, but it simply allows users to get more processing power for developing their business network applications in a cooperative processing environment. It does not define any new infrastructure, but it uses the existing structure and new user interface tools. It integrates these new tools and the concepts of the distributed architecture to define a new computing environment which will enhance productivity at much lower operating costs.
The new payroll system will utilize client/server based architecture with the use of thin clients running from a central terminal server located at the Data Center. The terminal server will communicate with the application server where the new payroll application will reside and the application server will communicate with the payroll database server.
In most cases today, a distributed computing architecture consists of very lightweight software agents installed on a number of client systems, and one or more dedicated distributed computing management servers. There may also be requesting clients with software that allows them to submit jobs along with lists of their required resources. An agent running on a processing client detects when the system is idle, notifies the management server that the system is available for processing, and usually requests an application package.
Setting up the network basis is necessary to the success of this project. A Client/Server network is needed to implement through a TCP/IP protocol. Each plant will function as Local Area Network linked together as a Wide Area Network. All the users with the access will have the ability to exchange information instantly. This configuration will generate the best and secured settings to create and direct the information to the users.
In contrast to the poorly defined Windows DNA (Distributed interNet Architecture), .NET is a tangible and easily defined software product. It is an application framework, meaning that it provides applications with the system and network services they require. The .NET services range from displaying graphical user interfaces to communicating with other servers and applications in the enterprise. It replaces Windows COM (Component Object Model) with a much simpler object model that is implemented consistently across programming languages. This makes sharing data among applications, even via the Internet, easy and transparent. .NET also substantially improves application scalability and reliability, with portability being a stated but not yet realized objective. These are clear benefits demonstrated by the pre-beta edition of .NET.
 Move to a industry standard infrastructure that would be managed centrally – a client server environment.
Thin-client computing now offers real hope for progress. The state of affairs described above is like a fat pitch don the middle of home plate, just begging for thin-client computing proponents to smack it out of the park. When it comes to total cost of ownership for desktop computing services, thin-client computing is a bottom-line winner. Yes users will have to five up some control of their desktops. Any yes, administrators will need to learn a new approach to application deployment. But the payback is so clear; thin clients' arrival is almost inevitable.
This memorandum will attempt to explain the Open Systems Interconnection Model, known more simply as the OSI Model. The OSI Model has seven levels, and these levels will be discussed in detail. Particular mention will be made to which level TCP/IP functions with the OSI Model.
Through personally developing my own server-client network, I was able to better understand the concepts of networking. I was individually able to manipulate the program to better undertake the communication aspect, the level of security, and organization of information in code and to the end-user. From this mini project, I learned the communication process between systems and how to first initiate a connection. I also learned the fundamentals of server sockets, regular sockets, print streams, and buffered readers in addition to multithreading, try-catches, and exceptions. And lastly, the utmost important aspect, I gained a full understanding of the concept of networking once I personally learned, through development, the intricate network
Thin Client or Server-based computing is a model in which applications are deployed, managed, supported and executed 100% on a server. It uses a multi-user operating system and a method for distributing the presentation of an application's interface to a client device. The server-based computing model employs three critical components. The first is a multi-user operating system that enables multiple concurrent users to log on and run applications in separate, protected sessions on a single server. The second is a highly efficient computing technology that separates the application's logic from its user interface, so only keystrokes, mouse clicks and screen updates travel the network. As a result, application performance is bandwidth-independent.
To build a good and stable network is extremely difficult. It takes a team of very knowledgeable engineers to put together a system that will provide the best service and will forfill the need for the companies users and clients. There are many issues that have to be resolved and many choices have to be made. The toughest choices IT managers have to make, are what will be the best server platform for their environment. Many questions must be answered. Which server software offers complete functionality, with easy installation and management? Which one provides the highest value for the cost? What kind of support and performance can be expected from this system? And most important of all is what is more secure? In this paper, Microsoft Windows NT Server is compared to UNIX, in the large commercial environment. The main focus of the comparison is on the areas of, reliability, compatibility, administration performance and security.
Architectural design refers to the mechanisms that are used to frame the structure of a computer-based system. Proper architectural designs enable a computer system to develop its compatibility feature. Compatibility in this sense refers to the manner in which the computer- based systems fulfill the needs of the users (Denford, O’Neill & Leaney, 2003). Transform characteristics can be considered as one of the methods to develop an efficient computer system (Losavio, Chirinos, Lévy & Ramdane-Cherif, 2003). Emphasizing the issue, the essay aimed at describing the architectural design of a computer-based system, which possesses distinct transform characteristics.
The TCP/IP is the most important internet operation protocol in the world. While IP protocol performs the mass of the functions which is needed for the internet to work. It does not have many capabilities which are essential and needed by applications. In TCP/IP model these tasks are performed by a pair of protocols that operate at the transport layer. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). These two protocols are vital when it comes to delivering and managing the communication of numerous applications. To pass on data streams to the proper applications the Transport layer must identify the target application. First, to be able to attain this, Transport layer assigns an application an identifier. In the TCP/IP model call this identifier a port number. Every individual software process needing to access the network is assigned a un...
It simplifies the storage and processing of large amounts of data, eases the deployment and operation of large-scale global products and services, and automates much of the administration of large-scale clusters of computers.
Server-based networks are higher in cost because money is invested for dedicated servers, network operating software, and network administrators with technical expertise required for network management and configuration. On a small network consisting of fewer than five workstations, client/server architecture is not recommended and is very costly.
Client-Server overuse occurs when too many employees on a network are using a central copy of a program at the same time. When using a program in this way, it must be stated in the license. By having more employees using the software than stated in the license, is defined as overuse.
