Sofiane Amarouche Assignment 1 1) In general terms what are the four distinct actions that a machine instruction can specify? A machine instruction can specify the following four distinct actions -Processor-memory: Such instructions involve data transfer between processor and memory. -Processor-I/O: Instructions may involve data transfer between Processor and I/O modules. -Data processing: Instructions involving arithmetic and logical operations on data. -Control: An instruction may specify that the sequence of execution be altered. For example, in a program any instruction may alter the memory address of the next instruction. 2) What is an interrupt? An interrupt is a signal informing a program that an event has occurred,…show more content…
It is the part of the operating system that loads first and it remains in main memory. Its responsibilities include managing the systems resources and the communication between hardware and software components.

Multiprogramming is a method of running several different programs in a computer at the same time 6) What is a process? Many definitions have been given for the term process including, - A program in execution - An instance of a program running on a computer -The entity that can be assigned to and executed on a processor -A unit of activity characterized by a single sequential thread of execution, a current state, and an associated set of system resources 7) What is the difference between windows Windows7 and Linux with regard to address space and processor support? The address space, is not really different, it's dependent on the processor of the machine Linux will run on any processor that;s relatively modern (arm, sparc, alpha, mips, ia64, i386, PPC) Windows 7 will only run on i386 ( x86 or
