What are abstractions for?

1.1.4 Abstraction >>> What are abstractions for >>> How Computers Work

 

By simplifying what a computer does, they make it easier to understand.

================================

There is no single representation, even at the hardware level, because things are represented differently in computer memory, on hard discs and when transmitted over networks (among other things).

================================

Compression algorithms typically work on low-level features like numbers.

================================

 

 

You don’t need to understand how each individual image is represented.

================================

 

I will discuss latter

There are many different abstractions of a computer; many ways of thinking about them.
