Fundamentals of Web Design and Development: Client Server Architecture

A set of flashcards covering key vocabulary and concepts related to Client/Server Architecture from the lecture notes.

Client/Server Model

Describes the relationship between a client that requests a service and a server that fulfills the request.

Web Server

A specific type of server that sends web pages and files in response to client requests.

Peer-to-Peer (P2P)

A symmetric relationship where each participant can act as both client and server.

Asymmetric Relationship

In client-server architecture, the client predominantly makes requests, whereas the server responds.

Three-tier Architecture

A type of client-server architecture that includes a Presentation Tier, Application Tier, and Data Tier.

Presentation Tier

The layer in a three-tier architecture that handles the user interface.

Application Server

A server that delivers applications to client computers and processes data for them.

Database Server

Stores data for application servers in a three-tier architecture.

n-tier Architecture

An architecture that separates processing among multiple servers to balance loads and improve scalability.

Web Hosting Service

An Internet hosting service that allows individuals and organizations to make their websites accessible online.

Bandwidth

The amount of data transferred over a network in a given time, impacting website performance.

Scripting Languages

Programming languages used to create dynamic content on web pages.

Traffic Congestion

Occurs when a large number of clients send requests to a server simultaneously, potentially causing problems.

Client Characteristics

Active (master) nature; sends requests and waits for server replies.

Server Characteristics

Passive (slave) nature; waits for requests and serves replies upon receipt.

Advantages of Client Server Model

Better security, centralized data management, scalable, user-friendly interfaces.

Disadvantages of Client Server Model

Possible traffic congestion, reliance on server uptime, vulnerabilities in case of server failure.
