Windows XP(operating system)
Windows XPThe client version of Windows superseding Windows 2000 and prior to Windows Vista. Introduced in 2001, XP was a major upgrade with many changes to the user interface. XP improved support for gaming, digital photography, instant messaging, wireless networking and Internet connection sharing. It also added a personal firewall (see Windows Firewall). Although XP is a client operating system, it also functions as a server (see peer-to-peer network).
Home Vs. Pro
XP Home Edition was designed for the consumer, and XP Professional was aimed at the office worker with added security and administrative options. For example, XP Pro can log in to a domain-based network in an office, but XP Home cannot. XP Pro can also be run remotely, and it supports Intel's Hyper-Threading (see Remote Desktop and HyperThreading).
A 64-bit version of XP also became available for Intel IA-64 machines as well as AMD's 64-bit CPUs. Originally code-named Whistler, the Windows XP operating system is .NET enabled. See Windows, .NET Framework and Windows Product Activation.
