Understanding Servers and Backends

Flashcards designed to help students review key vocabulary and concepts related to servers and backend systems.

Server

A program that responds to requests from clients, supplies data, and processes client information.

Client

A program that sends requests to servers, processes responses, and displays an interface for users.

Client-Server Interaction

The communication process between clients and servers over predefined protocols.

TCP

Transmission Control Protocol - A protocol used for reliable communication between computers in a network.

HTTP

Hypertext Transfer Protocol - The protocol used for transmitting data over the web.

MQTT

Message Queuing Telemetry Transport - A lightweight messaging protocol for small sensors and mobile devices optimized for high-latency networks.

Single Point of Failure (SPOF)

A part of a system that, if it fails, will stop the entire system from functioning.

Data Processing

The operation performed by servers to handle data received from clients.

Requests and Responses

The method by which clients ask for data from servers and receive information back.

Centralized Data Storage

A system where all data is stored in a single location, managed by a server.

Separation of Logic and Visualization

The architectural design principle that delineates server operations from user interface elements.

Server Applications

Software that runs on servers to manage and process tasks.

Client Applications

Software that runs on clients to interact with servers and present data to users.

Communication Protocols

Standardized methods for data transmission across networks.

Architecture

The structure and organization of a client-server system.

Pros of Client-Server Architecture

Benefits such as security, centralized control, and logical separation.

Cons of Client-Server Architecture

Drawbacks including vulnerability to single points of failure and potential high costs.

Game Server Example

A specific type of server that delivers data to players and accepts their inputs.

User Interface

The means through which clients interact with the server's data.

Program Behavior

The specific functions that a program performs in response to inputs.
