1. In conection-oriented system a HANDSHAKING process is
used i.e the process tsarts from the sender computer by
sending a request to start the transfer that is to be
acknowledged by the destination device before the data can
be send.
while in CONNECTIONLESS system no handshaking
process is used. if one computer wants to send data,it just
sends the data packet to the end system.

2. In conection-oriented system communication between the
sendr & receiver continues untill th etransmission has been
verified.thus it requires higher overhead & places greater
demand on bandwidth.
while the CONNECTIONLESS system requires less
overhead & bandwidth.

3. There is guranteed delivery of data in CONECTION-
ORIENTSD system.any packet that is not received by the
destination is resend by the sending device.
there is no confirmation that the data has been
received,thus there is no resending of data in
CONNECTIONLESS SYSTEM.thus transmission is not guranteed.

4. eg of connectio-oriented protocol is-TCP\IP & eg of
connectionless protocol is-UDP

Why are using 4ma to 20ma for signal transfer. Why not 0 to 20ma?
