What happens when a program is executed?
Once the program begins execution it is entirely copied to the RAM. Then the processor retrive a few instructions (it depends on the size of the bus) at a time, puts them in registers and executes them.
What are the steps of program execution?
Linker generates the executable module of a source program. Loader loads the executable module to the main memory for execution. Linker takes the object code generated by an assembler, as input. Loader takes executable module generated by a linker as input.
What does it mean to execute a line of code?
Execution is the process by which a computer interprets our program or performs the instructions of our program. For example, you have written a program to print your name.
What happens when we compile a code?
A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). … So, for a compiled language the conversion from source code to machine executable code takes place before the program is run.
What do you call a program in execution?
A program in execution is called a process.
Where a program is stored and executed?
The CPU. The CPU is the heart of the computer. A program is a sequence of instructions stored in main memory. When a program is run, the CPU fetches the instructions and executes or follows the instructions.
Is a program in execution?
Explanation: We know that a computer program is a set of instructions to be executed. And if the instructions are in execution, then it is called as process. In brief, a program in execution is called as process.
What is program execution cycle?
The main job of the CPU is to execute programs using the fetch-decode-execute cycle (also known as the instruction cycle). … When a program is being executed, the CPU performs the fetch-decode-execute cycle, which repeats over and over again until reaching the STOP instruction.
What are the stages of compilation and linking?
Four Steps of Compilation: preprocessing, compiling, assembly, linking.
- Preprocessing: Preprocessing is the first step. …
- Compiling: Compiling is the second step. …
- Assembly: Assembly is the third step of compilation. …
- Linking: Linking is the final step of compilation.

What are the three different ways of executing a form?
Answer. Answer: Here is your answer dude, Lethal injection is the most widely-used method of execution, but states still authorize other methods, including electrocution, gas chamber, hanging, and firing squad.
What execution means?
1 : the act or process of executing : performance. 2 : a putting to death especially as a legal penalty. 3 : the process of enforcing a legal judgment (as against a debtor) also : a judicial writ directing such enforcement. 4 : the act or mode or result of performance.
Which one is the starting point for the execution of a process?
In computer programming, an entry point is where the first instructions of a program are executed, and where the program has access to command line arguments. To start a program’s execution, the loader or operating system passes control to its entry point.
What is compiling in coding?
Compiling is the transformation from Source Code (human readable) into machine code (computer executable). … A compiler takes the recipe (code) for a new program (written in a high level language) and transforms this Code into a new language (Machine Language) that can be understood by the computer itself.
Why we compile the code?
A compiler is a program for automated translation of computer programs from one language to another. It translates input to output. Often, the input language is one that a given computer can’t directly execute (for example, because the language is designed to be human-readable).
What is purpose of compiler?
Compiler, Computer software that translates (compiles) source code written in a high-level language (e.g., C++) into a set of machine-language instructions that can be understood by a digital computer’s CPU. Compilers are very large programs, with error-checking and other abilities.
