  • One of the major functions of the physical layer is to move data in the form of electromagnetic signals across a transmission medium. Whether you are collecting numerical statistics from another computer, sending animated pictures from a design workstation, or causing a bell to ring at a distant control center, you are working with the transmission of data across network connections. Chapter 3 discusses the relationship between data, which are created by a device, and electromagnetic signals, which are transmitted over a medium.

  • GIS has been coming of age. Millions of people use one GIS or another every day, and with the advent of Web 2.0 we are promised GIS functionality on virtually every desktop and web-enabled cellphone. GIS knowledge, once restricted to a few insiders working with minicomputers that, as a category, don’t exist any more, has proliferated and is bestowed on students at just about every university and increasingly in community colleges and secondary schools.

  • With digital evidence, technology is always needed to process the digital data and therefore the only difference between a forensic and a non-forensic investigation of digital data is whether or not the evidence can be used in a court of law. A forensic investigation is a process that uses science and technology to develop and test theories, which can be entered into a court of law, to answer questions about events that occurred.

  • This is to be contrasted by the fact that the NII may well be the most important technology needed to facilitate a coordinated NSDI. The Mapping Science Committee (MSC) has recommended1 that the NSDI be developed to a level that would support the needs of the nation. The costs of creating and maintaining digital spatial data are high, so it is particularly important that spatial data collection not be duplicated,

  • Our goal in writing this book is to expose the inner workings of the modern digital computer at a level that demystifies what goes on inside the machine. The only prerequisite to Principles of Computer Architecture is a working knowledge of a high-level programming language. The breadth of material has been chosen to cover topics normally found in a first course in computer architecture or computer organization. The breadth and depth of coverage have been steered to also place the beginning student on a solid track for continuing studies in computer related disciplines....

  • Laser scanning technology has emerged as a research field in the science and engineering arena. Laser scanning performs a procedure to detect a surface using laser technology. A scanning device analyzes a real-world object to retrieve data on its shape and its appearance. The collected data can then be used to construct a digital three-dimensional model. The aim of the scanning is usually to create a point cloud on an object surface.

  • The following is an example of an IP address in 32-bit binary form and dotted decimal form. Binary IP Address: 11000000.10101000.00101101.01111001 Decimal IP Address: Binary data is made up of ones and zeros. Ones represent on and zeros represent off. Binary data can be grouped in varying increments, 110 or 1011. In TCP/IP binary data is usually grouped in eight digit groups called a Byte. A Byte, 8 bits, can range from 00000000 to 11111111 creating 256 combinations with decimal values ranging from 0 to 255.

  • Encryption is a widely used technique which involves making information indecipherable to protect it from unauthorised viewing or use, especially during transmission or when it is held on removable magnetic media. Encryption is usually based on a key(s) without which the information cannot be decoded (decrypted). The most widely used encryption system is DES (Data Encryption Standard) although increasingly this is being replaced commercially by the more secure public key system RSA.

  • For reliable communications to take place on a network, things like the physical method of signaling and the meaning of each signal or series of signals must be defined ahead of time. Create a simple physical network and agree on some basic rules for communication in order to send and receive data. This will be a digital network based on the American Standard Code for Information Interchange (ASCII). It will be similar to the old telegraph Morse code-based systems. In these older systems the only means of communicating over long distances was by sending a series of dots and dashes...

  • The deregulation of the telecommunications industry, creating pressure on new operators to innovate in service provision in order to compete with existing traditional telephone service providers, is and will be an important factor for an efficient use of the spectrum. It is certain that most of the information communicated over future digital networks will be data rather than purely voice. Hence, the demand for high-rate packet-oriented services such as mixed data, voice, and video services, which exceed the bandwidth of conventional systems, will increase.
