Windows audio architecture. Windows Driver Model supported by Win 98, Win ME, Win 2K and Win XP a single audio driver works for multiple Windows versions APIs DirectSound WinMM Kernel streaming multiple audio streams can be played at the same time

Unix Architecture. Typical computer system consists of: Hardware Operating system Applications and utilities Typical OS includes a user interface or command interpreter Unix is somewhat unique in that the command interpreter is not integrated with the OS but is a separate program.

ARM. Advanced RISC Machines. The ARM Instruction Set. Main features of the ARM Instruction Set. All instructions are 32 bits long. Most instructions execute in a single cycle. Every instruction can be conditionally executed. A load/store architecture

Module 22: Windows XP. History Design Principles System Components Environmental Subsystems File system Networking Programmer Interface. Windows XP . 32-bit preemptive multitasking operating system for Intel microprocessors. Key goals for the system: portability security

Process Description and Control. B.Ramamurthy. Introduction. The fundamental task of any operating system is process management. OS must allocate resources to processes, enable sharing of information, protect resources, and enable synchronization among processes.
