Definition: A knot, knob, protuberance or swelling.
Alright class, settle down now, let’s take a look and see,
At the word “nodes,” it’s quite tricky, you agree?
The dictionary gives us clues, a helpful little plea,
Saying "knot," "knob," “protuberance,” for all to clearly see!
Let's break it down in a way that makes sense and flows,
Think of a bumpy road where the pebbles grow.
A
node
is like one of those bumps you find,
A small rise or swelling, leaving no one behind.
It could be a knot in rope, a knob on a door,
Or even a swelling—don't you explore?
Sometimes in diagrams and drawings you’ll see,
Nodes are used to represent points, for you and me!
So remember this rhyme, it’s quite simple and neat,
A node is a bump, a knot, a little treat!
