PROCESSES AND THREADS

Processes and Threads

We can think of a thread as basically a lightweight process. In order to understand this let us consider the two main characteristics of a process:

Unit of resource ownership

-- A process is allocated:

·         a virtual address space to hold the process image

·         control of some resources (files, I/O devices...)

Unit of dispatching

- A process is an execution path through one or more programs:

·         execution may be interleaved with other processes

·         the process has an execution state and a dispatching priority
