Dell and Windows Server 2003 for 64-Bit Extended Systems
Windows Server 2003 for 64-Bit Extended Systems can provide higher performance for both 32-bit and 64-bit applications running on Dell PoweEdge Servers built on Intel Extended Memory 64-bit Technology (EM64T). The underlying architecture of Windows Server 2003 for 64-bit Extended Systems is based on 64-bit extensions to the industry-standard x86 instruction set, allowing today's 32-bit applications to run natively on 64-bit extended processors. At the same time, new 64-bit applications are executed in 64-bit mode, which processes more data per clock cycle, allows greater access to memory, and speeds numeric calculations. The end result is a platform that leverages the...

History of Operating Systems
The systems of the 1960's were also batch processing systems, but they were able to take better advantage of the computer's resources by running several jobs at once. So operating systems designers developed the concept of multiprogramming in which several jobs are in main memory at once; a processor is switched from job to job as needed to keep several jobs advancing while keeping the peripheral devices in use. For example, on the system with no multiprogramming, when the current job paused to wait for other I/O operation to complete, the CPU simply sat idle until the I/O finished. The...

Windows XP
A lot of time and effort has gone into making Windows XP Home Edition and Windows XP Professional easier to install and use. Take, for example, the improved Setup wizard that helps to make installation as pain-free as possible. This includes a new Dynamic Update feature, which lets the operating system update itself with new drivers, fixes, or other code updates directly from the Internet. With Windows XP installed, your startup times will be faster than they were with other Windows operating systems. Configuring a fresh install is also speedier thanks to a Transfer Files and Settings wizard, which lets...

Application Problems in Windows XP SP2
Now that Windows XP Service Pack 2 (SP2) is available at Windows Update for online update of both the XP Home Edition and XP Professional Edition platforms, you need to be prepared for the changes you’ll see as a result of the security controls XP SP2 installs and activates by default. A query of Microsoft's XP SP2 Knowledgebase articles posted during the past 2 weeks turned up a laundry list of installation and device-related bugs, information about the affects of the now disabled Alerter and Messenger services, problems related to the enabled firewall, third-party network backup, and other application problems....

Athlon 64 and Windows XP 64 Bit Edition - This is the Beta
For the past week, I've been running Windows XP 64 Bit. This version is still a beta version of the OS. In other words, should you try this for yourself, don’t expect full functionality. What this 64-bit operating system does allow is the running of 64-bit programs. Unfortunately, at this point I have none of those. (If you have one, and can spare a license...) Let's begin with the hardware: the Athlon64/FX/Opteron has the ability to run in three modes. The first is "Legacy," which almost everyone is using right now. That's where you have a 32-bit O/S, and 32-bit...

Windows XP 64-Bit Edition
This is preview software. In other words, there are still a lot of kinks to work out, and very little driver support. ATi has stated their unwillingness to make special drivers for an operating system that is not final, and other hardware vendors have also been slow on the uptake. I can't really say I blame them--by the time this operating system goes "gold", they will have spent a lot of time creating drivers and support for very few users. The only thing to be gained is experience compiling for this modified kernel. Thankfully though, VIA, Silicon Image and...
