When the Afrikaners (Boers) migrated northward from the Cape to escape British rule, they enountered the Zulu people. To protect their claims, the Boers formed the laager, a circle of wagons. As years passed, the laager acquired wider political dimensions and became a symbol of Afrikaner determination to survive under hostile conditions. Ian D. Smith, last colonial leader of Zimbabwe from 1964 to 1979, and F. W. de Klerk, the last white president of South Africa from 1988 to 1994, were the last defenders of the laager on the African continent. Rising nationalism and the devastation of...

Fiber optics is a transmission technique that uses electrical signals to modulate a light source and thereby produce an optical signal proportional to the electrical signal. These optical signals contain information that is transmitted via a glass waveguide to a light-sensitive receiver. Fiber optics has a distinct advantage over copper networks for some applications. The objective of this book is to explore monomode, as opposed to multimode, applications of fiber optics to local area networks (LANs), which have become a rather important aspect of this technology because of the...
