Processes- Making the System More Responsive and Useful
A method by definition build up of a code execution and resource ownership. A process has two main characteristics, code execution and resource ownership. Every application loaded into memory is represented as a process which is the controlling mechanism in a multitasking system. Operating systems in fact multitask the process representing user programs.
The system becomes more responsive and fully used while processes are multitasked. In many such systems, additional processes may be created by the application to provide concurrent execution within a program. Application efficiency will thus be enhanced because there will be multiple units of execution representing the program. When a new process is created, a copy of code and data are created and execution is initiated. Each process runs independently, but the created process has significant ties to the process that created it.
Q. Why do several systems store the operating system in firm ware and others on disk? Answer: For certain devices such like handheld PDAs and cellular telephones a disk with
Q. Likewise some systems support many types of structures for a file's data while others simply support a stream of bytes. What are the merits in addition to demerits? Answer:
Locks (also known as mutexes, short for mutual exclusion locks) provide mutual exclusion to shared data inside a critical session. They are implemented by means of two atomic routi

Differentiate pre-emptive and non-preemptive scheduling In a pre-emptive scheduling technique, CPU can be taken away from a process if there is a requirement while in a non-pre
Q. Consider a system in which a program is able to be separated into two parts: code and data. The CPU recognizes whether it wants an instruction (instruction fetch) or data (data
Is disk scheduling, other than FCFS scheduling, useful in a single-user environment? Explain your answer. In a single-user environment, the I/O queue usually is blank. Requests
