Modified Harvard architecture

Okay kiddo, have you ever played with LEGO before? Imagine if you had two different types of LEGO pieces that couldn't fit together – one type has four bumps and the other has three bumps. That's kind of like how a computer's architecture works – there are two different types of "blocks" for storing and processing information that are designed differently and can't work together.

In a normal computer, called the "von Neumann architecture," the blocks are combined in a certain way to make the computer work. But in a modified Harvard architecture, the blocks are kept separate from each other and have their own special paths for sending and receiving information.

Think of it like a bakery – there's a room for storing ingredients, and a separate room for baking the ingredients into delicious treats. In a modified Harvard architecture, the ingredients (data) and the kitchen (processing unit) are kept separate and have their own entrances and exits. This makes the computer work faster and more efficiently, because it doesn't have to wait for ingredients to move through the same pathway that the baked goods are coming out of.

So, in summary, a modified Harvard architecture is like separating the ingredients and the kitchen in a bakery so that they can work faster and more efficiently. It's a different way of building a computer that helps it run better.
