People don't appreciate this enough

if:

S - the house on the Left is ever for Sale

L - and the Lawn is still in Good condition

P - and the Sale Price is Below 500 thousand dollars

Then:

Buy the House

Let’s assume that we know S, L and P. What is the answer?

We have to have a way to get the answer, to calculate the result. This is a logical problem, and either we have a human being do it, or we get some sort of a machine to calculate the result. You might say, why would you need a machine for something so simple?

What if we had a thousand of these problems, appearing back to back? Quickly.

What if we had billions of these, and a human being could never solve it?

To solve these problems, we have Computers, that can be fed logical problems, and can spit out answers. Not only can they solve one problem, they are able to ‘move’ the cursor, and solve one problem after another in sequence.

And what makes this machine ‘Universal’ is that it can be programmed to do anything. You can program a loom, a typewriter, a fork lift. The idea is that with a program ‘reader’ and logical ‘executor’, you can write absolutely anything. Thus the machine is Universal.
