	Operating system (Linux Reviews)
		Apart from the kernel, an operating system is often distributed with system software that manages a graphical user interface (although Windows and Macintosh have integrated these programs into the operating system), as well as utility programs for tasks such as managing files and configuring the operating system.
		Like the term "operating system" itself, the question of what exactly the "kernel" should manage is subject to some controversy, with debates over whether things like file systems should be included in the kernel.
		Mainframe operating systems, such as IBM's z/OS, and embedded operating systems such as VxWorks, eCos, and Palm OS, are usually unrelated to Unix and Windows, except for Windows CE, Windows NT Embedded 4.0 and Windows XP Embedded which are descendants of Windows, and several BSDs, and Linux distributions tailored for embedded systems*.

		Students will learn about fundamental operating systems principles: definition and comparison of operating systems, hardware services for system protection and memory management, the kernel and shell, file I/O and buffering, file system, process and thread control, signals, interprocess communication and synchronization.
		They will be able to write Unix system programs that utilize system services, and they will understand the benefits and complications of buffering, asynchronous events, and synchronized communicating processes or threads.
		This course is essential preparation for the 5103 Operating Systems course; students must understand operating systems services and the systems programmers' view of an operating system from the outside before they can understand operating systems design from the inside.

		Sun’s UNIX operating system began life as a port of BSD UNIX to the Sun-1 workstation.
		With the predicted growth in multiprocessor systems, Sun invested heavily in the development of a new operating system kernel, with a primary focus on multiprocessor scalability.
		The framework implements several disk-based file systems (such as UNIX File System, MS-DOS File System, and CD-ROM File System), network file systems (such as NFS V2 and V3), and pseudo file systems (such as the PROCFS, the process file system that abstracts processes as files).

		As computer vendors are currently interested in building more powerful computers with faster processors and more memory, it may sound surprising that there is any interest left in embedded systems with 1024 bytes of RAM and a 1 Mhz processor.
		The comparison criterion is the memory footprint; we look into how much memory is required to run such an operating system and what services are available in such small memory space.
		The goal is to determine the smallest memory footprint for embedded operating systems and what are the factors that determine such a footprint.

	HP OpenVMS systems
		HP is bringing its OpenVMS operating system, middleware, and application portfolio to Intel® Itanium® architecture, which has a 64-bit model and basic system functions similar to the Alpha chip.
		AlphaServer system architecture supports both IEEE and VAX system floating-point formats in hardware, and OpenVMS compilers generate code using the VAX system formats by default, with options (on AlphaServer systems) to use IEEE formats.
		Irrespective of whether it was originally written for VAX systems or AlphaServer systems, an OpenVMS application that uses the default VAX system floating-point formats needs to produce equivalent behavior on the Itanium architecture using IEEE formats at the lowest level.

		However, they do sometimes accept non-disclosure agreements (NDAs) and include a limited number of closed-source HAL modules for specific device drivers in their source tree, in order to support the hardware of companies who cannot provide purely open source drivers (such as HALs to program software-defined radios so that vendors do not violate FCC regulations).
		A significant focus of development over the last five years has been "SMPng", a fine-grained SMP architecture intended to support higher levels of scalability, and KSE, an M:N threading implementation also targeted at scalability.
		Another attempt to profile worldwide BSD usage is the BSDstats Project, whose primary goal is to demonstrate to hardware vendors the penetration of BSD and viability of hardware drivers for the operating* system.
