Network Performance - Bandwidth, Throughput, Latency Explained?

Network Performance - Bandwidth, Throughput, Latency

Explained

Hello Guys! I'm 101Programmer, In this post, You going to see about Network Performance -- Latency, Throughput, and Bandwidth.

One of the main issues of the network is Performance. It’s not only important in networking and it's vital for all other things. 

How this Network performance is measured?

Network Performance is measured in the following fundamental ways. They are,

• Bandwidth
• Throughput
• Latency

 

let's start with a simple analogy,  there is a highway designed to transmit 1000 cars per minute. from one end to another end. If there is congestion, so it is reduced to 100 cars per minute. It actually capable of carrying 1000 cars but due to its congestion, it is possible only to transmit 100 cars.

From the above analogy -- 

• Bandwidth is 1000 cars per minute, [Capablity]

• Throughput is  100 cars per minute [Reality]

Bandwidth:

• The Bandwidth of a network is defined by the number of bits/hertz that can be transmitted in a certain period of time.
• Bandwidth is Capability.
• 
  

Throughput:

• The Throughput is defined as the actual amount of bits/hertz that transmit through the medium.
• Throughput is Reality.
• 
  

Latency [Delay] :

• Latency or also called Delay defines how long it takes for an entire message to sent which is the time from the first bit sent by machine A to the last bit received by Machine B.
•
