OCR 1.3.4 Client server and Peer to Peer

What is client-server architecture?

• A network architecture in which each computer or process on the network is either a client or a server.

• A type of computer monitor

• A type of computer software

• A type of network cable

Explain the concept of peer-to-peer network.

• Decentralized network where each participant can directly communicate with other peers

• Network where only one participant can communicate with others

• Centralized network where all communication goes through a single server

• Decentralized network where each participant can only communicate with a central authority

Name a few network protocols commonly used in client-server networks.

• HTTP, FTP, SMTP, DNS

• TCP, UDP, IP, Ethernet

• SSH, Telnet, SNMP, POP3

• HTML, CSS, JavaScript, XML

How does client-server communication work?

• The client and server do not communicate with each other.

• The server sends requests to the client, and the client responds with the requested information or action.

• The client sends requests to the server, and the server responds with the requested information or action.

• The client and server communicate through a third-party mediator.

What is peer-to-peer file sharing and how does it differ from client-server file sharing?

• Peer-to-peer file sharing only allows sharing within a single network, while client-server file sharing can be done across different networks.

• Peer-to-peer file sharing and client-server file sharing are the same thing.

• Peer-to-peer file sharing allows direct sharing between users, while client-server file sharing involves a central server.

• Peer-to-peer file sharing involves a central server, while client-server file sharing allows direct sharing between users.

List two advantages of client-server networks.

• 1. Centralized management and security control. 2. Scalability and flexibility.

• Limited management and security control. 2. Inflexibility and lack of scalability.

• No management and security control. 2. Limited scalability and flexibility.

• Decentralized management and security control. 2. Limited flexibility and scalability.

Describe the role of a client in a client-server network.

• Initiates requests for services or resources from the server

• Stores data on the server

• Manages the server's hardware

• Provides internet connection to the server

What are the main characteristics of a peer-to-peer network?

• Decentralization, shared resources, and direct communication between nodes

• Centralization, shared resources, and direct communication between nodes

• Centralization, private resources, and indirect communication between nodes

• Decentralization, individual resources, and direct communication between servers

Explain the importance of network protocols in client-server communication.

• Network protocols ensure smooth and reliable communication between client and server.

• Client-server communication can work without any protocols

• Client-server communication does not require reliable communication

• Network protocols are not important in client-server communication

Discuss the security implications of peer-to-peer file sharing.

• Peer-to-peer file sharing has no impact on security

• Peer-to-peer file sharing only enhances security measures

• Peer-to-peer file sharing reduces the risk of malware

• Peer-to-peer file sharing can lead to security risks such as the spread of malware, exposure of sensitive data, and potential legal issues related to copyright infringement.
