What Is A Compiler?
Compiler is used to translate the high-level language program into machine code at a time. It doesn’t require special instruction to store in a memory, it stores automatically. The Execution time is less compared to Interpreter.
Differentiate Between Ram And Rom?
RAM: Read / Write memory, High Speed, Volatile Memory. ROM: Read only memory, Low Speed, Non Voliate Memory.
What Is A Microprocessor?
Microprocessor is a program-controlled device, which fetches the instructions from memory, decodes and executes the instructions. Most Micro Processor is single- chip devices.

What Command Would You Use To Create An Empty File Without Opening It To Edit It?
You use the touch command to create an empty file without needing to open it. s a and e point to invalid commands, though either of these might actually be aliased to point to a real command. s b and c utilize editors, and so do not satisfy the requirements of the . actually touch is used to change the timestamps of a file if its exits, otherwise a new file with current timestamps will be created.
What Do You Type To Stop A Hung Process That Resists The Standard Attempts To Shut It Down?
The kill command by itself tries to allow a process to exit cleanly. You type kill -9 PID, on the other hand, to abruptly stop a process that will not quit by any other means. Also, pressing CtrI+C works for many programs. s b and d are only valid in some contexts, and even in those contexts will not work on a hung process.
