  What is client? 3 •A client is a single-user workstation that provides presentation services and the appropriate computing, connectivity and the database services and the interfaces relevant to the business need. • Clients are PCs or workstations on which users run applications. Clients rely on servers for resources, such as files, devices, and even processing power. • Two types of client :- 1) Thin client 2) Fat client
• 4.
  What is server? 4 •A server is one or more multi-user processors with share memory providing computing, connectivity and the database services and the interfaces relevant to the business need. • Servers are powerful computers or processes dedicated to managing disk drives (fileservers), printers(print servers), or network traffic(network servers ).

  What is clientserver architecture? 5 • Client-server architecture is a network architecture in which each computer or process on the network is either a client or a server. • Client-server architecture is producer/consumer computing architecture where the server acts as the producer and the client as a consumer.

  Types of clientserver architecture 7 • It divided into two types of applications 2 tier and 3 tier architecture. Basically high level we can say that 2-tier architecture is Client server application and 3- tier architecture is Web based application.

  Two-Tier architecture 8 • Thetwo-tier is based on Client Server architecture. The two-tier architecture is like client server application. The direct communication takes place between client and server. There is no intermediate between client and server. Because of tight coupling a 2 tiered application will run faster.

  9 • Let’s takea look of real life example of Railway Reservation two-tier architecture: • Let’s consider that first Person is making Railway Reservation for Ahmedabad to Bharuch by Gujarat express at Counter No. 1 and at same time second Person is also try to make Railway reservation of Ahmedabad to Bharuch by same train from Counter No. 2. Then… • The Two-tier architecture is divided into two parts: 1) Client Application (Client Tier) 2) Database or Server ( Server Tier)

  Three-Tier architecture 10 • Three-tierarchitecture typically comprise a presentation tier, a application or data access tier, and a server/data tier. Three layers in the three tier architecture are as follows: 1) Client layer 2) Application layer 3) Server/Data layer
• 11.
  11 1) Client layer: •It is also called as Presentation layer which contains UI part of our application. This layer is used for the design purpose where data is presented to the user or input is taken from the user. For example designing registration form which contains text box, label, button etc. 2) Application layer (Middleware) : • In this layer all application logic written like validation of data, calculations, data insertion etc. This acts as a interface between Client layer and Server Layer. This layer is also called the intermediary layer helps to make communication faster between client and data layer. 3) Server/Data layer: • In this layer actual database is comes in the picture. Data Access Layer contains methods to connect with database based on our input data.
