2. Latency :
Latency is the amount of time a message takes to traverse a system. In a
computer network, it is an expression of how much time it takes for a packet
of data to get from one designated point to another. It is sometimes measured
as the time required for a packet to be returned to its sender.
The chain of events that occur when you press that button are:
You press the “Add to Cart” button.
The browser identifies this as an event and initiates a request to the website’s
servers. The clock for latency starts now.
The request travels to the site’s server with all the relevant information.
The site’s server acknowledges the request and the first half of the latency is
completed.
The request gets accepted or rejected and processed.
The site’s server replies to the request with relevant information.
The request reaches your browser and the product gets added to your cart.
With this, the latency cycle is completed.
3. It is usually measured as a round trip delay - the time taken
for information to get to its destination and back again. ...
Latency is usually measured in milliseconds (ms).
4. delay ;
The amount of time it takes for the first bit ttravel over a link between sender
and reciever
5. Propagation delay
Propagation delay refers to the amount of time it takes for the first bit to travel
over a link between sender and receiver.
transmission delay
The transmission delay between the times that the first and last bits of the packet
are transmitted
Queuing delay
Queuing delay refers to the time that a packet waits to be processed in the buffer
of a switch. The delay is dependent on the arrival rate of the incoming packets,
the transmission capacity of the outgoing link, and the nature of the network’s
traffic
Processing delay
Processing delay is the time taken by a switch to process the packet header. The
delay depends on the processing speed of the switch.
