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.
rapidly chooses how to convey the set of uses and framework servers over different machines in the cloud. Large portions of the conventional parallel applications for the most part utilize an altered number of strings on the other hand procedures characterized as a parameter toward the begin of the application. The choice for the number of strings is frequently chosen by the client in a push to completely use the parallel assets of the framework or to take care of top demand of a specific administration. fos utilizes the duplicated server model which permits extra transforming units to be alterably included amid runtime permitting the framework to attain a finer use for element workloads and lightening the client from such
The internet works on the basis that some computers act as ‘servers’. These computers offer services for other computers that are accessing or requesting information, these are known as ‘clients’. The term “server” may refer to both the hardware and software (the entire computer system) or just the software that performs the service. For example, Web server may refer to the Web server software in a computer that also runs other applications or it may refer to the computer system dedicated only to the Web server applicant. For example, a large Web site could have several dedicated Web servers or one very large Web server.
New customer machines were introduced in every one of the focuses these machines were associated by means of web to a bunch of servers which are utilizing Oracle database programming. The lattice servers share the workload of the whole exchange among them likewise the procedure is adjusted utilizing Cisco load balancers to disseminate it equally among the
This also provided the ability to handle large volumes of client requests without creating unwanted delays, thus, low latency and high availability were achieved. Network load balancer provided a continuous service by automatically detecting any failures of a server and redirecting client traffic among the remaining servers. Scalability was another reason to use a server cluster. As traffic increases, additional servers can be added to the cluster if needed to handle the extra
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
 Move to a industry standard infrastructure that would be managed centrally – a client server environment.
Peer-to-peer is a communications model in which each party has the same capabilities and either party can initiate a communication session. Other models with which it might be contrasted include the client/server model and the master/slave model. In some cases, peer-to-peer communications is implemented by giving each communication node both server and client capabilities. In recent usage, peer-to-peer has come to describe applications in which users can use the Internet to exchange files with each other directly or through a mediating server.
JavaNet, unlike a typical cafe, will provide a unique forum for communication and entertainment through the medium of the Internet. JavaNet is the answer to an increasing demand. The public wants: (1) access to the methods of communication and volumes of information now available on the Internet, and (2) access at a cost they can afford and in such a way that they aren't socially, economically, or politically isolated. JavaNet's goal is to provide the community with a social, educational, entertaining, atmosphere for worldwide communication.
Traditionally websites were made using HTML and CSS. Over the time when websites became heavier and complicated, scripting languages like PHP, Python, and Perl were used with front end developed in previous mentioned technologies (HTML and CSS). JavaScript was introduced and made the web pages more interactive. With time and increased usage, jQuery was introduced. These were libraries of JavaScript functions used frequently in the web pages. But still people using these technologies were called “JavaScript User” and not “JavaScript Developer”. Node.js allows you to run JavaScript code on server side, outside the browser.

This white paper identifies some of the considerations and techniques which can significantly improve the performance of the systems handling large amounts of data.
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.
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.
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...
With the design separated into smaller logical pieces, network design problems can be easier to solve through divide and conquer techniques. Vendors who follow the model will produce equipment that is much more likely to be compatible with equipment from other vendors. The OSI model also provides for more extensible network designs. New protocols and other network services are easier to add to a layered architecture.
