The i-mode service by NTT DoCoMo is a mobile phone service in Japan that provides its customers with both voice and comprehensive data services. With an i-mode phone, users can exchange i-mode e-mail and obtain information from i-mode menu sites and i-mode compatible Internet sites. The i-mode phone contains a browser that displays i-mode compatible HTML web pages. Beginning with the 505i phones, you can view Macromedia Flash Lite movies from the i-mode browser. You can also use the phones’ My Picture and Standby Screen applications to view Flash Lite movies. Although a number of manufacturers produce 505i phones, all of them support the same Flash Lite functionality.

A Public Key Infrastructure (PKI) binds cryptographic public keys to physical entities through digital certificates. A PKI includes components that issue digital certificates and distribute certificate status information. PKI users select one or more certificate issuers as trust anchors, and establish security services based on certificates that may be validated using one of their trust anchors.

The many variants of the Unix operating system require use of a mode of thought that s significantly different from the one that s required by simpler operating systems. Think Unix introduces readers to important fundamental and intermediate Unix commands and, in the process, inculcates them in the Unix way of thinking. It s a worthy goal in a world with more Linux users than ever, and author Jon Lasser accomplishes it. He s both a capable writer and a knowledgeable user of Unix shell commands. Lasser uses bash under Red Hat Linux in most examples--which usually apply equally well to other Unix variants--and makes asides about other shells and environments, as needed.

In the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic communication for emergency operations, disaster relief efforts, and military networks. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of mobile ad hoc networks. A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the
