  • Most input/output devices reside the computer case. These devices communicate with what is inside the computer case through cables attached to the case at a connection called a port, sending data and/or instructions to the computer and receiving them from the computer. Most computers have their ports located on the back of the case, but some models put the ports on the front of the case for easy access. The most popular input devices are a keyboard and a mouse, and the most popular output devices are a monitor and a printer. The keyboard is the primary input devices of a computer.

  • This book considers electronic devices applied to process analog signals in in strument making, automation, measurements, and other branches of technology. They perform various transformations of electrical signals: scaling, integration, logarithming, etc. Such devices are considered in tutorials on electronics. The need in their deeper study is caused, on the one hand, by the great demands of extending the range of input signals, as well as increasing the accuracy and speed of such devices, which usually receive insufficient attention.

  • We will demonstrate a novel graphical interface for correcting search errors in the output of a speech recognizer. This interface allows the user to visualize the word lattice by “pulling apart” regions of the hypothesis to reveal a cloud of words simlar to the “tag clouds” popular in many Web applications. This interface is potentially useful for dictation on portable touchscreen devices such as the Nokia N800 and other mobile Internet devices.

  • CODING TECHNIQUES Many errors in a computer system are committed at the bit or byte level when information is either transmitted along communication lines from one computer to another or else within a computer from the memory to the microprocessor or from microprocessor to input/ output device. Such transfers are generally made over high-speed internal buses or sometimes over networks. The simplest technique to protect against such errors is the use of error-detecting and errorcorrecting codes.

  • A modem computer consists of one or more processors, some main memory, disks, printers, a keyboard, a mouse, a display, network interfaces, and various other input/output devices. All in all, a complex system. If every application programmer had to understand how all these things work in detail, no code would ever get written. Furthermore, managing all these components and using them optimally is an exceedingly challenging job.

  • Communication systems consist of an input device, transmitter, transmission medium, receiver and output device, as shown in Fig. 1.1. The input device may be a computer, sensor or oscillator, depending on the application of the system, while the output device could be a speaker or computer. Irrespective of whether a data communications or telecommunications system is used, these elements are necessary.

  • I was privileged to have witnessed the evolution of medical informatics in the United States during its fi rst six decades. Donald A. B. Lindberg, Director of the National Library of Medicine, advised me that documenting this history would be a worthy project since during this period the country moved into a new information era, and it was obvious that computers were having a major infl uence on all of medicine. In this book I address history as a chronological accounting of what I considered to be signifi cant events.

  • For simple applications, switching devices such as contactors or solid-state relays can be used to control electrical power. The electrical power in a process can be regulated by varying the ON and OFF times of these devices. But in many processes this provision of energy in large blocks will cause significant variations in the process output. As an example, it would not be possible to control lighting levels simply by using such two-state on/off switching elements. Neither could good temperature controllers be implemented in this way...
