In telecommunications, a circuit switching network is one
that establishes a circuit (or channel) between nodes and
terminals before the users may communicate, as if the nodes
were physically connected with an electrical circuit.

The bit delay is constant during a connection, as opposed to
packet switching, where packet queues may cause varying
packet transfer delay. Each circuit cannot be used by other
callers until the circuit is released and a new connection
is set up. Even if no actual communication is taking place
in a dedicated circuit that channel remains unavailable to
other users. Channels that are available for new calls to be
set up are said to be idle.

Ex is Trunk call between two phones(Telephone connectivity)

Packet switching is a digital network communications method
that groups all transmitted data, irrespective of content,
type, or structure into suitably-sized blocks, called
packets. The network over which packets are transmitted is a
shared network which routes each packet independently from
all others and allocates transmission resources as needed.
The principal goals of packet switching are to optimize
utilization of available link capacity, minimise response
times and increase the robustness of communication. When
traversing network adapters, switches and other network
nodes, packets are buffered and queued, resulting in
variable delay and throughput, depending on the traffic load
in the network.
