  • There are many occasions when data need to be transmitted over a voice communication network. Many people use a computer to connect to their Internet Service Provider via the telephone lines to transmit and receive data, check their email, surf the Web, etc. Telephone networks were originally built for human speech, not for computer data and is unsuitable for digital communication in its raw form.

  • Note the following details of the code protection feature on Microchip devices: • • Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature.

  • A Grid can be defined as a layer of networked services that allow users single sign-on access to a distributed collection of compute, data, and application resources. The Grid services allow the entire collection to be seen as a seamless information processing system that the user can access from any location. Unfortunately, for application developers, this Grid vision has been a rather elusive goal. The problem is that while there are several good frameworks for Grid architectures (Globus [1] and Legion/Avaki [18]), the task of application development and deployment has not become easier....

  • Computer processing is performed by transistors, which are switches with only two possible states: on and off. All computer data is converted to a series of binary numbers– 1 and 0. For example, you see a sentence as a collection of letters, but the computer sees each letter as a collection of 1s and 0s.

  • As computer networks become cheaper and more powerful, a new computing paradigm is poised to transform the practice of science and engineering. Driven by increasingly complex problems and propelled by increasingly powerful technology, today’s science is as much based on computation, data analysis, and collaboration as on the efforts of individual experimentalists and theorists. But even as computer power, data storage, and communication continue to improve exponentially, computational resources are failing to keep up with what scientists demand of them....

  • This book is an introduction to computer science. Computer science is the study of computer hardware, algorithms, and data structures and how they fit together to provide information systems. Each of these topics can be studied at various levels. For example, physicists study the properties of matter that allow hardware components to be designed, electrical engineers study how the components can be combined to produce circuits, and computer engineers study how circuits can be combined to produce computers.

  • In Oracle8 we saw the addition of bitmap indexes, function-based indexes, as well as reverse key indexes and star index structures. We also saw the Oracle SQL optimizer becoming more intelligent about the way indexes are used by SQL statements. In Oracle9i, we have the index skip scan, the and_equal hint to combine individual indexes into a contaminated index, as well as specialized bitmap access methods to improve the speed of data warehouse queries.

  • Oracle 10g Data Mining Application Developers guide WW Oracle Database 10g, released in 2003 and the current release, enables grid (the g in 10g) computing. A grid is simply a pool of computers that provides needed resources for applications on an as-needed basis. The goal is to provide comput- ing resources that transparently scale to the user community, much as an electri- cal utility company can deliver power to meet peak demand by accessing energy from other power providers’ plants via a power grid.

  • The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process.
