Is int 0x80 the only interrupt number used when programming a Linux build?

Question

We use only 80H in assembly programming to request a service for the linux kernel?

What is the usefulness of other interrupt numbers on Linux?

I am switching from windows to linux.

Answer 1

int3(debug breakpoint) and int 80h(old system call) are the two software interrupts commonly used on Linux. Hardware interrupts are used by device drivers, but they probably don't concern you.
