Answer / hariprasad
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.

hi shyam i am putting urs question here I am facing one problem in my layer 2 switch I don’t know the problem is on switch side or client side. The problem is some PC (not all) are stop participate in LAN they don’t send or recd. Packet from switch and if I check RJ45 (with LAN tester)from PC side the packet and 8 pin wire is working fine and after that process of LAN tester I plug RJ 45 in PC now PC start recd/ send packets what is the problem I don’t understand even client side no virus found RJ45 is ok and switch has no problem bcoz other PC is working fine Cable (cat 5 ) is also fine bcoz I didn’t crimp again just check in LAN tester and start working fine. Plz any one solve this matter. And after lan tester process pc is working fine and after 2 or 3 hour it again start same problem and again same process lan tester I have used
