Tick the four most accurate statements regarding peer-to-peer and client-server networks.  Peer-to-peer networks must have a central server. Client-server networks generally offer greater security than peer-to-peer networks. Peer-to-peer networks can support millions of users with no loss of performance. The server will determine which users can access the files on a client-server network. In a client-server network each client functions both as a client and as a server simultaneously. If one computer crashes it has no effect on the other users in a client-server network. A client-server network is cheaper to set up than a peer-to-peer network. Peer-to-peer networks always require an employee to manage the network. In a peer-to-peer network only one computer is allowed to use the printer. In a peer-to-peer network computers can communicate and share files with every other computer on the network.
