1.0 BASIC CONCEPTS 1.1 What is a Process? In computing‚ a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OSf a process may be made up of multiple threads of execution that execute instructions concurrently (Robbins‚ Kay. A. and Steven Robbins‚ 1996). A computer program is a passive collection of instructions; a process is the actual execution of those instructions. Several processes

system is known as a process. Associated with a process is the current status of the activity‚ called the process state. This state includes the current position in the program being executed (the value of the program counter) as well as the values in the other CPU registers and the associated memory cells. Roughly speaking‚ the process state is a snapshot of the machine at a particular time. At different times during the execution of a program (at different times in a process) different snapshots

Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontiguous‚ thus allowing a process to be allocating physical memory wherever the latter is available. 3.

time in a useful manner. A single-threaded process‚ on the other hand‚ will not be capable of performing useful work when a page fault takes place. Therefore‚ in scenarios where a program might suffer from frequent page faults or has to wait for other system events‚ a multi-threaded solution would perform better even on a single-processor system. 4.4 Which of the following components of program state are shared across threads in a multithreaded process? a. Register values b. Heap memory c. Global
