Detailed explanation-1: -Explanation : Wireless Area Network is not a computer network. The other three are computer network types.
Detailed explanation-2: -Point-to-Point Protocol (PPP) is a TCP/IP protocol that is used to connect one computer system to another. Computers use PPP to communicate over the telephone network or the Internet. A PPP connection exists when two systems physically connect through a telephone line. You can use PPP to connect one system to another.
Detailed explanation-3: -Many examples of point-to-point communications networks include leased wires, microwave relay links and two-way radio. Radio and television broadcasting are examples of point to multipoint communication systems. The Point to Point Protocol (PPP) is used to create direct communication between two nodes in the network.
Detailed explanation-4: -Services Not provided by the PPP protocol It does not support flow control mechanism. It has a very simple error control mechanism. As PPP provides point-to-point communication, so it lacks addressing mechanism to handle frames in multipoint configuration.
