Answer 2

Answer:

How do we give commands to the computer?

The computer has a CPU, a central processing unit, which is the thing that you can command to do things.

This CPU has a set of “instructions” that it can recognize, which are a pattern of voltages in the circuits that will cause the CPU to perform a specific conceptual function, such as adding two values together, or “reading” some value[s] from memory, for example.

So by sending such a specific pattern/instruction to the CPU, you command it to do things. By combining a large number of such instructions in sequence (a “program”), you can make it do all of the things computers do, and things we haven’t even tried to make them do, yet.

However, because this is not a very intuitive or easy way to command the computer to do complicated things, we instead use programming languages to “explain” what we want it to do. A program called a “compiler” will then read what you’ve explained, and turn that into a program that the computer can run (a “.exe” file for Windows, for example).

But you could open notepad, write a bunch of numbers that refer to the instructions for the CPU, and then save that as a .exe file, and run it. Theoretically, you could. You’d also need to study how your operating system works in more detail, though, as it’ll expect certain things from you in order for the program to be able to run at all.

Or, if you want to run it without an operating system, you’ll need to study how to make a bootable file.
