Busy loop - what kind of cycle is this?

Question

Machine translation from one language to another

According to the meaning, I understand that this is an endless cycle (active cycle). I can be wrong. In Habré, this word is used without translation. Help me understand the meaning.

.text
.globl	start
.code16

start:
        jmp	start

In such a code, he met me.

Answer 1

Yes, this is a loop that constantly checks for some condition. Constantly spends processor time checking conditions, and therefore busy.
Something like

while(status != DONE) {
    Sleep(500);
}

An alternative is the callback mechanism, when the execution of the thread is stopped and continued by an external signal.
