  • 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.

  • 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.

  • 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.
