Explanation:
Detailed explanation-1: -There are two main system calls to manipulate memory, namely brk and sbrk. Both brk and sbrk change the amount of space allocated for the calling process’s data segment.
Detailed explanation-2: -A system call is implemented by a “software interrupt” that transfers control to kernel code; in Linux/i386 this is “interrupt 0x80”. The specific system call being invoked is stored in the EAX register, abd its arguments are held in the other processor registers.
