Client Server & Peer to Peer Networks Flashcards

All 6 cards in this deck

What is the role of the server in a client-server network?: It provides services and resources to clients when they request them, e.g. file storage, web pages, printing, and it manages user accounts and security.
What is the role of a client in a client-server network?: It requests services and resources from the server, and is the computer the user works on.
What are the roles of the computers in a peer-to-peer network?: All computers are equal peers; each one acts as both client and server, sharing files and resources directly with the others.
True or false? In a peer-to-peer network one computer acts as a central server for the others.: False. There is no central server; every computer has equal status and shares resources directly.
Give two advantages of a client-server network over a peer-to-peer network.: Files and backups are managed centrally on the server, and security/user accounts can be controlled centrally by an administrator.
A home with three computers wants to share files cheaply and has no technical staff. Which network model is recommended, and why?: Peer-to-peer; no expensive dedicated server is needed and it is simple to set up and maintain.
