How programming language is programmed? How exactly a computer understands the programming language, if there is no language programmed for programming yet?

Using lower level languages?

Built up from the 1s and 0s

Ok. How the computer gets the 01 language without previous programming?

1s and 0s are electrical signals. On and off. They control when power is diverted around the hardware.

OK. You steel need to explain what 1 and 0 mean to the computer.

I just did? Read it again.

Or Google it.

Assembly language. Each instruction in assembly translates to a unique bunch of 0s and 1s. When a processor reads that particular combination of 0s and 1s, it does a corresponding operation.

OK. How the assembly language was programmed?

When a company like Intel or AMD manufacture their processor, they design it to perform particular actions like add, move, multiply, etc for a particular combination of voltages(1's and 0's).

OK. Thanks.

You should look up "Compiler Construction".

There do exist languages intended for this or parts of this (i.e. flex, bison etc) but a compiler/interpreter can be written in most any programming language.

The author of this ebook is popular on Reddit /r/programming... It's actually fairly good. :/
