Mark Zbikowski
Mark "Zibo" Joseph Zbikowski (born March 21, 1956) is a former Microsoft Architect and an early computer hacker. He started working at the company only a few years after its inception, leading efforts in MS-DOS, OS/2, Cairo and Windows NT. In 2006, he was honored for 25 years of service with the company, the third employee to reach this milestone, after Bill Gates and Steve Ballmer. He retired the same year from Microsoft. He was the designer of the MS-DOS executable file format, and the headers of that file format start with his initials: the ASCII characters 'MZ' (0x4D, 0x5A). Early years Zbikowski was born in Detroit, Michigan, in 1956. While attending The Roeper School (then known as Roeper City And Country School) from 1961 to 1974, he developed an interest in mathematics and computers.

Michigan Mathematics Prize Competition
The Michigan Mathematics Prize Competition (MMPC) is an annual high school mathematics competition held in Michigan. First founded in 1958, the competition has grown to include over 10,000 high school participants (although middle-schoolers may also participate through a high school). The director and host of this competition changes every three years, the most recent director being Stephanie Edwards of Hope College. This competition consists of two parts, which are added together to determine score: : Part I: A 40 question, multiple-choice exam open to all Michigan high schoolers : Part II: A 5 question, proof exam given only to the Top 1000 scorers on Part I The Top 100 scorers on the combined score of both parts of the competition are honored at an awards banquet, usually at the host university, although recent years have seen more than 100 people being awarded due to ties. Problem difficulty The problems on the competition range from basic algebra to precalculus and are wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File System
In computing, file system or filesystem (often abbreviated to fs) is a method and data structure that the operating system uses to control how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stopped and the next began, or where any piece of data was located when it was time to retrieve it. By separating the data into pieces and giving each piece a name, the data are easily isolated and identified. Taking its name from the way a paper-based data management system is named, each group of data is called a "file". The structure and logic rules used to manage the groups of data and their names is called a "file system." There are many kinds of file systems, each with unique structure and logic, properties of speed, flexibility, security, size and more. Some file systems have been designed to be used for specific applications. For example, the ISO 9660 file system is designe ...

Architecture Of Windows NT
The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode. It is a preemptive, reentrant multitasking operating system, which has been designed to work with uniprocessor and symmetrical multiprocessor (SMP)-based computers. To process input/output (I/O) requests, they use packet-driven I/O, which utilizes I/O request packets (IRPs) and asynchronous I/O. Starting with Windows XP, Microsoft began making 64-bit versions of Windows available; before this, there were only 32-bit versions of these operating systems. Programs and subsystems in user mode are limited in terms of what system resources they have access to, while the kernel mode has unrestricted access to the system memory and external devices. Kernel mode in Windows NT has full access to the hardware and system resources of the computer. The Windows NT kernel is a hybrid kernel; the architecture compri ...

Installable File System
The Installable File System (IFS) is a filesystem API in MS-DOS/PC DOS 4.x, IBM OS/2 and Microsoft Windows that enables the operating system to recognize and load drivers for file systems. History When IBM and Microsoft were co-developing OS/2, they realized that the FAT file system did not offer some of the features modern OSes would require, and Microsoft began developing the High Performance File System (HPFS), codenamed ''Pinball''. Instead of coding it inside the kernel, as FAT was, Microsoft developed a "driver-based" filesystem API that could allow them and other developers to add new filesystems to the kernel without needing to modify it. When Microsoft stopped working on OS/2, IBM continued using the IFS interface and Microsoft implemented a similar one in Windows NT. Implementations IFS in DOS 4.x IFS in OS/2 The IFS provided a basic and powerful interface for programming filesystems. It was introduced in 1989 in OS/2 1.20, along with the HPFS filesystem.

Plug And Play
In computing, a plug and play (PnP) device or computer bus is one with a specification that facilitates the recognition of a hardware component in a system without the need for physical device configuration or user intervention in resolving resource conflicts. The term "plug and play" has since been expanded to a wide variety of applications to which the same lack of user setup applies. Expansion devices are controlled and exchange data with the host system through defined memory or Input/output, I/O space port addresses, direct memory access channels, interrupt request lines and other mechanisms, which must be uniquely associated with a particular device to operate. Some computers provided unique combinations of these resources to each slot of a CPU cache, motherboard or backplane. Other designs provided all resources to all slots, and each peripheral device had its own address decoding for the registers or memory blocks it needed to communicate with the host system.

Tim Paterson
Tim Paterson (born 1 June 1956) is an American computer programmer, best known for creating 86-DOS, an operating system for the Intel 8086. This system emulated the application programming interface (API) of CP/M, which was created by Gary Kildall. 86-DOS later formed the basis of MS-DOS, the most widely used personal computer operating system in the 1980s. Biography Paterson was educated in the Seattle Public Schools, graduating from Ingraham High School in 1974. He attended the University of Washington, working as a repair technician for The Retail Computer Store in the Green Lake area of Seattle, Washington, and graduated ''magna cum laude'' with a degree in Computer Science in June 1978. He went to work for Seattle Computer Products as a designer and engineer. He designed the hardware of Microsoft's Z-80 SoftCard which had a Z80 CPU and ran the CP/M operating system on an Apple II.

Ruddigore
''Ruddigore; or, The Witch's Curse'', originally called ''Ruddygore'', is a comic opera in two acts, with music by Arthur Sullivan and libretto by W. S. Gilbert. It is one of the Savoy Operas and the tenth of fourteen comic operas written together by Gilbert and Sullivan. It was first performed by the D'Oyly Carte Opera Company at the Savoy Theatre in London on 22 January 1887. The first night was not altogether a success, as critics and the audience felt that ''Ruddygore'' (as it was originally spelled) did not measure up to its predecessor, '' The Mikado''. After some changes, including respelling the title, it achieved a run of 288 performances. The piece was profitable, and the reviews were not all bad. For instance, the ''Illustrated London News'' praised the work of both Gilbert and, especially, Sullivan: "Sir Arthur Sullivan has eminently succeeded alike in the expression of refined sentiment and comic humour. In the former respect, the charm of graceful melody pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Gondoliers
''The Gondoliers; or, The King of Barataria'' is a Savoy Opera, with music by Arthur Sullivan and libretto by W. S. Gilbert. It premiered at the Savoy Theatre on 7 December 1889 and ran for a very successful 554 performances (at that time the fifth longest-running piece of musical theatre in history), closing on 30 June 1891. This was the twelfth comic opera collaboration of fourteen between Gilbert and Sullivan. The story of the opera concerns the young bride of the heir to the throne of the fictional kingdom of Barataria who arrives in Venice to join her husband. It turns out, however, that he cannot be identified, since he was entrusted to the care of a drunken gondolier who mixed up the prince with his own son. To complicate matters, the King of Barataria has just been killed. The two young gondoliers must now jointly rule the kingdom until the nurse of the prince can be brought in to determine which of them is the rightful king. Moreover, when the young queen arrives ...
