Unit2 Os Pdf Process Computing Thread Computing Typically, processes are fairly heavy (like ms word), while the threads are lighter (like background save option). the table below highlights some of the differences between the two. The os picks the new processes from the secondary memory and put all of them in the main memory. the processes which are ready for the execution and reside in the main memory are called ready state processes. Emphasise that the process control block contains sufficient information so that it is possible to interrupt a running process and later resume execution as if the interruption had not occurred. Whenever a command is issued in unix linux, it creates starts a new process. for example, pwd when issued which is used to list the current directory location the user is in, a process starts.

Whenever a command is issued in unix linux, it creates starts a new process. for example, pwd when issued which is used to list the current directory location the user is in, a process starts. Key difference between processes and threads is that multiple threads share parts of their state. typically, allow multiple threads to read and write same memory. Simple and powerful primitives for process creation and initialization. unix fork creates a child process as (initially) a clone of the parent [linux: fork() implemented by clone() system call]. Many modern operating systems have extended the process concept to allow a process to have multiple threads of execution and thus to perform more than one task at a time. To make the students understand the basic operating system concepts such as processes, threads, scheduling, synchronization, deadlocks, memory management, file and i o subsystems and protection.
