Synchronous data transmission is a data transfer method in which a continuous stream of data signals is accompanied by timing signals (generated by an electronic clock) to ensure that the transmitter and the receiver are in step (synchronized) with one another. The data is sent in blocks (called frames or packets) spaced by fixed time intervals.
The server should be able to block unauthorized access, a good firewall but still, enable those authorized to have an access. However, there should be security on vulnerable parts of the system that may lead to corruption and easy access to data thieves.
This delay in routers is what we called Packetization delay
or also called Accumulation delay. Packetization delay is the time required for
the information to pass on the wires. The data rate of the links that passes
thru the wires cause the delay.
