Mnemonics is derived from a Greek word “mnemonikós”, which means Mind, this learning technique is used for information intention.  Mnemonics allows us to easily transform unrelated information into a form which is easily understood by our brain than its original form. In simple words, it helps us to remember unrelated information easily.

Here is a technique to remember a list of unrelated items in order using Mnemonics:

• Start at the top of the list and make up a simple story connecting the first item to the next.
• Continue by connecting the second item to the third, and so on.
• When your story is done and the list is removed, you’ll have a mental picture of  that story, as you recall its progression, it will lead you from one remembered item to the next.

For example, if you want to remember bridge selection process in Switches.

The normal order is :

Step 1 : Lowest Root Bridge ID (BID)
Step 2 : Lowest Path cost to Root Bridge
Step 3 : Lowest Sender BID
Step 4 : Lowest Port ID

So here is the trick, focus on these words Root, Path, Sender, Port. Using first alphabets of root, path, sender and port the sentence will be as follow:
