Windows 2008 vs. Windows 2003 OS

There are many differences between the Windows 2003 server and the Windows 2008 server. I will cover both each with their own paragraph, and then compare them in the last paragraph. Each paragraph will cover information on processor management, memory management, I/O, and the networking and file systems. Before I get started let me explain what they both generally are. Windows 2003 is a server system whereas Windows 2008 is a client/server system with a combination of Windows 2003 and Vista. Windows 2003 is usually used in offices and Windows 2008 is used more with personal computers. Windows 2008 is 32 bit whereas Windows 2003 is 16bit and sometimes 32 bit, so installation of 2008 is faster.

First, I will start out with explaining the basics of the Windows 2003 server. Windows 2003 server functions in two different modes: the executive mode (kernel mode) and the open non privileged user mode. Low-level system services, interfaces to the hardware, and system data are controlled by the kernel mode. The user mode handles everything else that is subject to user interface; such as the default Win32 subsystem, optional subsystems, and applications. The executive (kernel) mode has five different segments of operations; The Hardware Abstraction Layer (HAL), the microkernel, the device drivers, the executive managers, and the executive services buffer. These five segments handle all the operations that are hidden from the user. The Hardware Abstraction Layer is at the base of the windows executive mode. The HAL provided code that fixed cross-platform issues. The microkernel manages base-level functions and controls and dispatches threads. Dispatcher objects launch and synchronize events, timers, mutants, and threads. Control objects review system interruptions, thread profiles, and regulate virtual address processes. The device drivers are set of instructions that coordinate the OS...
