Which one of the following is not a client-server application?

• A. Internet chat
• B. Web browsing
• C. E-mail

Answer 1

(A) Typical internet chat is a client/server app, since a client makes a connection to a central server and receives update. There are some chat systems that work on  a P2P model.

(B) Web browsing is client/server, where a browser is the client and the web page is served up by a server.

(C) E-mail is typically thought of as a client/server app, although hops will be made between POP servers.

(D) Ping uses ICMP protocol, and a ping client sends a request to a destination and gets back a response. It is a connection testing tool.
