WAN Technologies - POINT–TO-POINT
WAN technologies are based on serial transmission at the physical layer. This means that the bits of a frame are transmitted one at a time over the physical medium. The bits that make up the Layer 2 frame are signaled one at a time by physical layer processes onto the physical medium. The signaling methods include Nonreturn to Zero Level (NRZ-L), High Density Binary 3, (HDB3), and Alternative Mark Inversion (AMI). These are examples of...

Getting started with Infosphere data architect
InfoSphere Data Architect (IDA), formerly known as Rational Data Architect, is the premier tool from IBM for database design and more!. Learn how to use it in conjunction with DB2 Express-C, the no-charge edition of DB2. Since IDA is built on top of Eclipse, you can integrate it easily with other tools from IBM such as Data Studio also built using Eclipse technology. This book is for beginners in IDA and also in data modeling.

Advanced Structured MaterialsVolume 21Series Editors Andreas Öchsner Lucas F. M. da Silva Holm
The development of nanomaterials opens the possibility for new materials with outstanding properties compared to classical engineering materials. These materials can find applications in different fields such as medical treatment or structural mechanics. This monograph focuses on two major groups of nanomaterials, i.e.nanoparticels and nanocomposites. Nanopartices, for example in the form of hollow particles, allow for new possibilities in...

RADIO-FREQUENCY AND MICROWAVE COMMUNICATION CIRCUITS
Wireless technology continues to grow at a tremendous rate, with new applications still reported almost daily. In addition to the traditional applications in communications, such as radio and television, radio-frequency (RF) and microwaves are being used in cordless phones, cellular communication, local area networks, and personal communication systems. Keyless door entry, radio-frequency identification, monitoring of patients in a hospital or...

Somewhere, separated from you by just a few degrees, is not Kevin Bacon, but an 800-pound gorilla demanding that you adopt radio frequency identification, or RFID — a technology you may have never even heard of until just a few months ago. Chances are that gorilla wears a stylish blue smock with a yellow smiley face on it and greets you with a “Welcome to Wal-Mart.” If not Wal-Mart, the US Department of Defense, Target, Albertsons, Best...

Radar Systems, Peak Detection and Tracking
This book is written to provide continuity to the reader on how radar systems work, how the signals captured by the radar receivers are processed, parameterized and presented for tracking, and how tracking algorithms are formulated. Continuity is needed because most radar systems books have been written that concentrate on certain specialized topics assuming a prior knowledge of the reader to background principles.

For students writing applications that run over TCP/IP, or for those responsible for managing and maintaining a TCP/IP internet, this book's innovative approach helps readers at all levels to truly understand how TCP/IP really works. Rather than just describing the protocols from an abstract, standards-related point of view-describing what the standards say the protocol suite should do-TCP/IP Illustrated, Volume 1 actually shows the protocols...

A Brief History of Security “Well, I never heard it before,” said the Mock Turtle, “but it sounds uncommon nonsense.” —Lewis Carroll, Alice in Wonderland. Secret communication achieved by hiding the existence of a message is known as steganography. The word is derived from the Greek word “steganos,” meaning cov- ered and “graphin” meaning to write.

This chapter helps you prepare for the exam by covering the following Planning objective: Given a scenario, identify valid network configurations. . This is a very general objective as there are many aspects of a valid network configuration. Essentially, this objective indicates that you will need to have the background provided by the Networking Essentials exam and understand what configurations of TCP/IP are valid. . This chapter...
