Packet Switching: A method of transmitting data group with the
concern of content, type or structure into suitably-sized blocks. Data packets
are shared in a shared network which route each packet independently from
others. The core objective of packet switching is to optimize the usage of
available link capacity and robustness of communication improvement.
Cell Switching: The process of packet switching is resembles in
cell switching. The difference is the packets length is fixed. ATM technology
is popular for packet switching.
Resembles the same process that of cell switching and difference is the process
of setting up the circuit itself is the part of the process. Between two
parties, the channel is setup, through which the data is transmitted and the
channel is torn down soon after the data transmission. Circuit switching
technology is familiar to use in CCNA candidates in ISDN.
