Architects Applications by Making Use of Multitasking
As the capability of computer hardware keeps increasing, operating systems are presented with overwhelming opportunities. Operating systems now have more processing power, core controls for concurrent applications, and very large address space to accommodate new programs.
A high degree of processor utilization can only be achieved when many application use system resources concurrently. It is the duty of the operating system to provide mechanisms for this concurrency.
This describes and architects applications by making use of multitasking. It provides a full discussion of multitasking, including both process and thread. In addition, this describes the mechanics of programming applications using the available controls of each operating system. It also explains the ownership of data and resources managed by these operating systems constructs.
