Unit 1 Assignment 1: Networking-Tier Architecture
Networking - Client/Server Architecture
Introduction to 2-Tier Architecture
2-tier architecture is used to describe client/server systems where the client requests resources and the server responds directly to the request, using its own resources. This means that the server does not call on another application in order to provide part of the service.
Introduction to 3-Tier Architecture
In 3-tier architecture, there is an intermediary level, meaning the architecture is generally split up between: 1. A client, i.e. the computer, which requests the resources, equipped with a user interface (usually a web browser) for presentation purposes 2. The application server (also called middleware), whose task it is to provide the requested …show more content…
By client, we mean the application that runs on a personal computer or workstation and relies on a server to perform some operations.Thick or thin client architecture is actually quite similar. In both cases, you can consider it as being the client application running on a PC whose function is to send and receive data over the network to the server program. The server would normally communicate that information to the middle-tier software (the backend), which retrieves and stores that information from a database.While they share similarities, there are many differences between thick and thin clients. Thick and thin are the terms used to refer to the hardware (e.g., how a PC communicates with the server), but the terms are also used to describe applications. While this article deals specifically with hardware issues, be sure to check back as we will continue our Thick and Thin discussion as related to applications.Thin ClientsA thin client is designed to be especially small so that the bulk of the data processing occurs on the server. Although the term thin client often refers to software, it is increasingly used for the computers, such as network computers and Net PCs, that are designed to serve as the clients for client/server architectures. A thin client is a network computer without a hard disk drive. They act as a simple terminal to the server and require constant communication with the server as well.
