Study Notes
Client-Server Relationship
- A server provides resources or services to clients in a networked environment.
- Servers respond to client requests, processing data and fulfilling functions like storage, database access, or web hosting.
Server Applications
- Examples of server applications include web servers, file servers, and email servers, which manage requests and deliver content to clients.
Client Role
- In the client-server model, a client initiates communication by sending requests to the server for data or services, effectively starting the interaction.
Key Characteristic of Client/Server Systems
- Client/server systems are characterized by their division of tasks, where servers manage resources and clients utilize those services.
Protocol for Web Interaction
- Hypertext Transfer Protocol (HTTP) governs interactions between web servers and web clients, enabling the exchange of web content.
Role of TCP in Communication
- Transmission Control Protocol (TCP) ensures reliable communication between clients and servers, establishing a connection and managing data transmission.
Function of Network Access Protocols
- Network access protocols define how clients connect to the network and communicate with servers, facilitating the transmission of requests and responses.
Data Link Management Protocols
- Data link management protocols handle the formatting and transmission of packets from Internet Protocol (IP) to ensure they are delivered accurately over the network.
Network Interface Cards (NICs)
- NICs are hardware components that enable communication over a network, translating data into signals for transmission and facilitating the connection to the network infrastructure.
Representation of Bits and Signals
- Physical layer protocols dictate how bits are represented on physical media, including electrical impulses or optical signals, governing the conditions of the transmission medium.

Description
Test your knowledge on client/server systems, where a client sends a request to a server and the server responds by carrying out a function. Understand the role of protocols in client/server communication using common instances like web browsers and web servers.
