How to explain complex concepts

Describe how your concept fits into a particular category or how it can be broken down into parts that can be described more easily; this is useful in showing your reader how your concept fits into a big picture, how it can be divided, and how it’s a key tool that will help you in explaining complex issues, and the audience to understand.

An analogy involves explaining an unfamiliar concept in terms of a familiar one.

For example analogy between a computer firewall and a bank, you could say that (honest and unarmed) people don’t just go directly into a bank and remove cash. They might go to the counter clerk and identify themselves; the clerk then will make sure they have money in their account and give them the money they require. Similarly, a firewall ensures that people who want information and access to an IT network are trusted to have that access.
