Windows

Windows Server 2008 is built from the same code base as Windows Vista; therefore, it shares much of the same architecture and functionality. Since the code base is common, it automatically comes with most of the technical, security, management and administrative features new to Windows Vista such as the rewritten networking stack (native IPv6, native wireless, speed and security improvements); improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features such as BitLocker and ASLR; improved Windows Firewall with secure default configuration; .NET Framework 3.0 technologies, specifically Windows Communication Foundation, Microsoft Message Queuing and Windows Workflow Foundation; and the core kernel, memory and file system improvements.
Processors and memory devices are modeled as Plug and Play devices, to allow hot-plugging of these devices. This allows the system resources to be partitioned dynamically using Dynamic Hardware Partitioning; each partition has its own memory, processor and I/O host bridge devices independent of other partitions.

Linux

Linux is nothing but an operating system that was started by Linus Torvalds, at the University of Helsinki in Finland. Linux is used for a large number of applications such as networking, development of software and as end-user platform. People often consider Linux to be an excellent and a not very expensive substitute to a lot of other expensive operating systems. Because of Linux’s good functions and its availability, it is quite in demand all across the world and a large number of s/w programmers are making use of the Linux’s source code in order to meet their individual needs.
