In most networks,not every sender/receiver pair can be connected.

Data communications via circuit switching involves three phases.These phases are

Having multiple paths from one station to another through a network contributes to reliability.

Almost all wide area networks (WAN)user circuit switching.

The major application that uses circuit switching networks is the telephone system,thus most data transferred using this type of network is voice traffic.

In a circuit switching network,the path that will be used through the network is determined prior to any data transfer.

Interconnection of computer systems is not reliable when using circuit switched networks.

Basic packet switching technology has recently been developed to replace circuit switching.

Which of the following is NOT a reason for network jitter when using packet switching networks?

In circuit switching networks,channel capacity between each pair of stations and/or nodes along the connection path must be reserved regardless if used or not.

Use of digital transmission for applications such as telephone requires that a dedicated connection be established across the network.

It is desirable to have only one path from sender to receiver to avoid excess costs.

Which of the following is NOT one of the stated advantages of packet switching over circuit switching?

Switching nodes are devices that enable data to be moved from senders to receivers.

The public telephone network is a good example of a circuit switched network.
