Client And Server Architecture

Today, most organizations are turning to client server architecture. The client server tries to balance the processing between the client and the server by running several logic at the same time. In these networks, the client is responsible for the presentation logic and the server is responsible for data access logic and data storage. Application logic can reside on the client or on the client on the server, or it can be split in two. These are many ways that application logic can be split between client and server.

The client server architecture is completely flexible for Hures multiclient programs. Because the client-server architecture, application processing and data management is a logically separate process, it is a very flexible and scalable way to build system software. Unlike typical client / server applications, this architecture is part of a two-tier application that supports multiple clients, supports client disconnection, and adds an application web browser (the web server is a separate part is). ) But what happens when the Web browser downloads and runs the Java applet? If the applet does not access the network during execution, is it a single-tier application or a two-tier application? For the present purpose, we say that self-contained applets are single-tier applications because they are entirely contained on the client computer.

The client-server architecture has two general architectural models. In two-tiered architecture and three tier architecture dual-tier architecture, because the server has more disk space and power than the PC, the application is on the server, not the client, and the data is placed in the server along with the application. In a three-tiered architecture, the load is distributed across two different servers rather than loading one server and interfering with the other. These servers are database servers, and application server data and applications are split between these servers. The client simply requests and displays the data. In this layer, each server is used to process data or application requests, so it is easier to manage available resources and less contention. (6)
