Richard Rashid
Richard Farris Rashid is the founder of Microsoft Research, which he created in 1991. Between 1991 and 2013, as its chief research officer and director, he oversaw the worldwide operations for Microsoft Research which grew to encompass more than 850 researchers and a dozen labs around the world. Before joining Microsoft in 1991, Rashid had been the developer of the Mach kernel during his tenure as a professor of computer science at Carnegie Mellon University. The Mach multiprocessor operating system kernel developed by Rashid has had a lasting influence in the design of modern operating systems, including the design of Windows NT, and remains at the core of several operating systems such as NeXTSTEP, GNU Hurd, macOS, iOS, OSF/1, and Tru64 UNIX. Rashid's Mach kernel pioneered the concepts of microkernel architecture and its impact can be traced in today's computing landscape with hundreds of millions of people still using Mach based operating systems thirty years after its creati ...

Microkernel
In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC). If the hardware provides multiple rings or CPU modes, the microkernel may be the only software executing at the most privileged level, which is generally referred to as supervisor or kernel mode. Traditional operating system functions, such as device drivers, protocol stacks and file systems, are typically removed from the microkernel itself and are instead run in user space. In terms of the source code size, microkernels are often smaller than monolithic kernels. The MINIX 3 microkernel, for example, has only approximately 12,000 lines of code. History Microkernels trace their roots back to Danish computer pioneer Per Brinch Hansen and his tenure in Danish computer compan ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Lebanon
Lebanon ( , ar, لُبْنَان, translit=lubnān, ), officially the Republic of Lebanon () or the Lebanese Republic, is a country in Western Asia. It is located between Syria to the north and east and Israel to the south, while Cyprus lies to its west across the Mediterranean Sea; its location at the crossroads of the Mediterranean Basin and the Arabian hinterland has contributed to its rich history and shaped a cultural identity of religious diversity. It is part of the Levant region of the Middle East. Lebanon is home to roughly six million people and covers an area of , making it the second smallest country in continental Asia. The official language of the state is Arabic, while French is also formally recognized; the Lebanese dialect of Arabic is used alongside Modern Standard Arabic throughout the country. The earliest evidence of civilization in Lebanon dates back over 7000 years, predating recorded history. Modern-day Lebanon was home to the Phoenicians, a m ...

Marjayoun
Marjayoun ( ar, مرج عيون: Lebanese pronunciation), also Marj 'Ayoun, Marjuyun or Marjeyoun (lit. "meadow of springs") and Jdeideh / Jdeida / Jdeidet Marjeyoun, is a Lebanese town and an administrative district, the Marjeyoun District, in the Nabatieh Governorate in Southern Lebanon. Geography Marjayoun is above sea level, standing on the west side of the Jordan Rift Valley just across from the ancient regional capital, Caesarea Philippi, which was located at the foot of Mount Hermon on the east side of the Rift Valley. It is not to be confused with the Banias Springs at Caesarea Philippi. Marjeyoun stands on a hill facing Mt Hermon to the east, the Crusader castle of Beafort, set above the Litani River and overlooking Mount Amel (Jabal Amel), to the west, the Mount Lebanon range with the Rihan and Niha peaks to the north, with the fertile Marjeyoun plains extending southward into the Galilee plains and the Golan Heights.

Lebanese People
The Lebanese people ( ar, الشعب اللبناني / ALA-LC: ', ) are the people inhabiting or originating from Lebanon. The term may also include those who had inhabited Mount Lebanon and the Anti-Lebanon Mountains prior to the creation of the modern Lebanese state. The major religious groups among the Lebanese people within Lebanon are Shia Muslims (27%), Sunni Muslims (27%), Maronite Christians (21%), Greek Orthodox Christians (8%), Melkite Christians (5%), Druze (5.2%), Protestant Christians (1%). The largest contingent of Lebanese, however, comprise a diaspora in North America, South America, Europe, Australia and Africa, which is predominantly Maronite Christian. As the relative proportion of the various sects is politically sensitive, Lebanon has not collected official census data on ethnic background since 1932 under the French Mandate. It is therefore difficult to have an exact demographic analysis of Lebanese society. The largest concentration of people of ...

Interactive TV
Interactive television is a form of media convergence, adding data services to traditional television technology. It has included on-demand delivery of content, online shopping, and viewer polls. Interactive TV is an example of how new information technology can be integrated vertically into established technologies and commercial structures. History Prior to the development of interactive television, interaction could only be simulated. In the 1950s, there were limited efforts to provide an illusion of interactive experience, most overtly with ''Winky Dink and You'', which encouraged viewers to draw on a vinyl sheet they would attach to a television set. QUBE operated an interactive cable television service in Ohio from 1977 to 1984. An interactive video-on-demand (VOD) television service was proposed in 1986 in Japan, where there were plans to develop an "Integrated Network System" service. It was intended to include various interactive services, including videotelephony, home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications pro ...

Data Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding; encoding done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a signal. ...
