Hard disk drive of the system in called primary memory and secondary memory is Random Access Memory(RAM). Either a program written in High Level Language(HLL) or a executable code generated by the sequence of works done by pre-processor, compiler and assembler, resides in secondary memory of the system. To start an execution, operating system allocates some space in the main memory, for the program to be executed and loads the program in the secondary memory to the allocated space. The piece of work which is loaded by the operating system to the main memory in order to execute program is called processEvery program loaded by operating system will create a focus boundary(or process body), a partitioned memory area where all memory requirements for the execution of program is satisfied.Variable which will not change its value through out life time of process is called static variable and variables which are globally accessible in a process known as global variable.Heap area is reserved f…
