Having an understanding of assembly language makes one aware of −
- How programs interface with OS, processor, and BIOS;
- How data is represented in memory and other external devices;
- How the processor accesses and executes instruction;
- How instructions access and process data;
- How a program accesses external devices.
Other advantages of using assembly language are −
-
It requires less memory and execution time;
-
It allows hardware-specific complex jobs in an easier way;
-
It is suitable for time-critical jobs;
-
It is most suitable for writing interrupt service routines and other memory resident programs.
