University Of Cambridge Computer Laboratory
The Department of Computer Science and Technology, formerly the Computer Laboratory, is the computer science department of the University of Cambridge. it employed 56 faculty members, 45 support staff, 105 research staff, and about 205 research students. The current Head of Department is Professor Alastair Beresford. History The department was founded as the Mathematical Laboratory under the leadership of John Lennard-Jones on 14 May 1937, though it did not get properly established until after World War II. The new laboratory was housed in the North Wing of the former Anatomy School, on the New Museums Site. Upon its foundation, it was intended "to provide a computing service for general use, and to be a centre for the development of computational techniques in the University". The Cambridge Diploma in Computer Science was the world's first postgraduate taught course in computing, starting in 1953. In October 1946, work began under Maurice Wilkes on EDSAC (''Electronic Del ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Gates Building, Cambridge
The William Gates Building, or WGB, is a square building that houses the University of Cambridge Computer Laboratory, Computer Laboratory at the University of Cambridge, on the University's West Cambridge site in JJ Thomson Avenue south of the Madingley Road in Cambridge, England. Construction on the building began in 1999 and was completed in 2001 at a cost of Great British Pound, £20 million. Opened by Maurice Wilkes, it was named after William H. Gates Sr., the father of Microsoft founder Bill Gates. The Bill & Melinda Gates Foundation provided 50% of the money for the building's construction. Building features The building has the following features: * The glass wall in the "fishbowl," a communal seating area in the building, is decorated with a paper-tape representation of the original EDSAC "Initial Orders" (boot program) written by David Wheeler (computer scientist), David Wheeler and of a program written by Maurice Wilkes in 1949 to compute squares * The building's m ...

High-level Programming Language
A high-level programming language is a programming language with strong Abstraction (computer science), abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language ''elements'', be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language. The amount of abstraction provided defines how "high-level" a programming language is. In the 1960s, a high-level programming language using a compiler was commonly called an ''autocode''. Examples of autocodes are COBOL and Fortran. The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse. However, it was not implemented in his time, and his original contributions were largely isolated from other developments due to World War II, aside from the language's influe ...

Formal Semantics Of Programming Languages
In programming language theory, semantics is the rigorous mathematical study of the meaning of programming languages. Semantics assigns computational meaning to valid string (computer science), strings in a programming language syntax. It is closely related to, and often crosses over with, the Semantics of logic, semantics of mathematical proofs. Semantics describes the processes a computer follows when Execution (computing), executing a program in that specific language. This can be done by describing the relationship between the input and output of a program, or giving an explanation of how the program will be executed on a certain computer platform, platform, thereby creating a model of computation. History In 1967, Robert W. Floyd published the paper ''Assigning meanings to programs''; his chief aim was "a rigorous standard for proofs about computer programs, including formal verification, proofs of correctness, equivalence, and termination". Floyd further wrote: A semant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Formal Verification
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of a system with respect to a certain formal specification or property, using formal methods of mathematics. Formal verification is a key incentive for formal specification of systems, and is at the core of formal methods. It represents an important dimension of analysis and verification in electronic design automation and is one approach to software verification. The use of formal verification enables the highest Evaluation Assurance Level ( EAL7) in the framework of common criteria for computer security certification. Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code in a programming language. Prominent examples of verified software systems include the CompCert verified C compiler and the seL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Usability
Usability can be described as the capacity of a system to provide a condition for its users to perform the tasks safely, effectively, and efficiently while enjoying the experience. In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use. The object of use can be a software application, website, book, tool, machine, process, vehicle, or anything a human interacts with. A usability study may be conducted as a primary job function by a ''usability analyst'' or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer. Usability includes methods of measuring usability, such as needs analysis and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Information Security
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, Data breach, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g., electronic or physical, tangible (e.g., Document, paperwork), or intangible (e.g., knowledge). Information security's primary focus is the balanced protection of data confidentiality, data integrity, integrity, and data availability, availability (also known as the 'CIA' triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process. To stand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Platform Virtualization
In computing, virtualization (abbreviated v12n) is a series of technologies that allows dividing of physical computing resources into a series of Virtual machine, virtual machines, Operating system, operating systems, processes or containers. Virtualization began in the 1960s with IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. In hardware virtualization, the ''host machine'' is the machine that is used by the virtualization and the ''guest machine'' is the virtual machine. The words ''host'' and ''guest'' are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a ''hypervisor'' or ''virtual machine monitor''. Hardware virtualization is not the same as hardware emulation. Hardware-assisted virtualization facilitates building a virtual machine monitor and allows guest OSes to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cambridge Ring (computer Network)
The Cambridge Ring was an experimental local area network architecture developed at the Computer Laboratory, University of Cambridge starting in 1974 and continuing into the 1980s. It was a ring network with a theoretical limit of 255 nodes (though such a large number would have badly affected performance), around which cycled a fixed number of packets. Free packets would be "loaded" with data by a sending machine, marked as received by the destination machine, and "unloaded" on return to the sender; thus in principle, there could be as many simultaneous senders as packets. The network ran over twin twisted-pair cabling (plus a fibre-optic section) at a raw data rate of 10 megabits/sec. There are strong similarities between the Cambridge Ring and an earlier ring network developed at Bell Labs Nokia Bell Labs, commonly referred to as ''Bell Labs'', is an American industrial research and development company owned by Finnish technology company Nokia. With headquarters locat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Cambridge Computing Service
The University of Cambridge Computing Service provided computing facilities across the University of Cambridge between 1970 and 2014. It was located primarily on the New Museums Site, Free School Lane, in the centre of Cambridge, England but, in September 2013 moved to the Roger Needham Building on the West Cambridge site. The Computing Service shares a common ancestry with the University of Cambridge Computer Laboratory. Founded on 14 May 1937 ''to provide a computing service for general use, and to be a centre for the development of computational techniques in the University'' as the ''Mathematical Laboratory'' (under the leadership of John Lennard-Jones), it was not until 2001 that the provision of computing services across the University and Colleges was fully separated from computing research and teaching. On 30 March 2014, the Computing Service merged with thManagement Information Services Division (MISD)of thUnified Administrative Service (UAS)to create thUniversit ...
