Client-Server Architecture Flashcards
(12 cards)
What is a Client-Server network?
A Client-Server network is a type of network where multiple client devices request and receive services from a centralized server. The server manages resources, security, and data access.
What are the key characteristics of Client-Server networks?
They have centralized control, servers handle requests and provide services, clients depend on servers, and the system can scale by adding more clients or servers.
What is a server in a Client-Server model?
A server is a powerful computer that provides resources or services such as file storage, printing, email, or web hosting to client devices on the network.
What is a client in a Client-Server model?
A client is a device (like a PC, tablet, or smartphone) that sends requests to a server for resources or services and receives responses in return.
What are examples of services provided in a Client-Server network?
Services include web services (HTTP), file services (FTP), email services (SMTP), print services, and database access.
What are the advantages of a Client-Server network?
Advantages include centralized security, easier management of resources, scalability, regular data backups, and the ability to control user access.
What are the disadvantages of a Client-Server network?
Disadvantages include higher cost, server dependency (single point of failure), complexity in setup, and the need for dedicated administrators.
Why is centralized security a benefit in Client-Server networks?
Because all user accounts, permissions, and security policies are controlled from one location, making it easier to manage and enforce rules.
How does a Client-Server network handle data backup?
The server typically handles automatic and centralized data backups for all clients, reducing the risk of data loss across the network.
What happens if the server fails in a Client-Server network?
If the server fails, clients cannot access shared services or resources, which can halt productivity until the server is restored.
In what environments are Client-Server networks commonly used?
They are commonly used in businesses, schools, government offices, and large organizations where centralized control and resource management are needed.
How does a Client-Server network differ from a Peer-to-Peer network?
In Client-Server, a central server provides services to clients. In Peer-to-Peer, all devices can act as both servers and clients, sharing resources directly.
