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. Linker combines all the object modules of a source code to generate an executable module.

What are the steps involved in program execution?

The following steps are involved in the execution of a program: – Fetch: The control unit is given an instruction. – Decode: The control unit then decodes the newly received instruction. – Execute: During the execution the Control unit first commands the correct part of hardware to take action.

What are the five execution steps?

Those stages are, Fetch, Decode, Execute, Memory, and Write. The simplicity of operations performed allows every instruction to be completed in one processor cycle.

What is program execution in computer architecture?

Execution in computer and software engineering is the process by which a computer or virtual machine reads and acts on the instructions of a computer program. Each instruction of a program is a description of a particular action which must be carried out, in order for a specific problem to be solved.

What are the three main steps in the program execution cycle?

It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.

What are the five stages of a machine cycle?

The process of cycling instructions may also be known as the E-cycle (execution cycle), I-cycle (instruction cycle), fetch-decode-execute cycle, or fetch-execute cycle.
