SYMBIAN OS 90% of the CPUs in the world are not in desktops and notebooks. They are in embedded systems like cell phones‚ PDAs‚ digital cameras‚ camcorders‚ game machines‚ iPods‚ MP3 players‚ CD players‚ DVD recorders‚ wireless routers‚ TV sets‚ GPS receivers‚ laser printers‚ cars‚ and many more consumer products. Most of these use modern 32-bit and 64-bit chips‚ and nearly all of them run a fullblown operating system. But few people are even aware of the existence of these operating systems

Chapter 1 – 8 Essay Question Review 1. Explain why an operating system can be viewed as a resource allocator. Ans: A computer system has many resources that may be required to solve a problem: CPU time‚ memory space‚ file-storage space‚ I/O devices‚ and so on. The operating system acts as the manager of these resources. Facing numerous and possibly conflicting requests for resources‚ the operating system must decide how to allocate them to specific programs and users so that it can operate the

not necessarily through technological means. Telecommunication‚ however‚ is talking through technology meaning phones‚ Internet‚ radio etc... In earlier times‚ telecommunications involved the use of visual signals‚ such as beacons‚ smoke signals‚ semaphore telegraphs‚ signal flags‚ and optical heliographs‚ or audio messages such as coded drumbeats‚ lung-blown horns‚ and loud whistles. In modern times‚ telecommunications involves the use of electrical devices such as the telegraph‚ telephone‚ and teleprinter

CHAPTER 7 Deadlock is a problem that can arise only in a system with multiple active asynchronous processes. It is important that the students learn the three basic approaches to deadlock: prevention‚ avoidance‚ and detection (although the terms prevention and avoidance are easy to confuse). It can be useful to pose a deadlock problem in human terms and ask why human systems never deadlock. Can the students transfer this understanding of human systems to computer systems? Projects can involve

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).
