What are the three types of switching techniques? There are 3 common switching techniques: Circuit Switching. Packet Switching. Message Switching. What are the four causes of packet delay? In packet switched networks, there are four types of commonly identified delays – processing, queuing, transmission and propagation delays. Processing delay is the CPU cycles needed to […]

How many billion years did it take for humans to appear on Earth? Recognizable humans emerged at most 2 million years ago, a vanishingly small period on the geological scale. The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era, after a geological crust started […]

Why is liquid water important to life? Even organisms that live in very dry places need water to live. One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get […]

How do I compare two numbers as a percentage? First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is […]
