Understanding the Linux Kernel helps readers understand how Linux performs best and how
it meets the challenge of different environments. The authors introduce each topic by
explaining its importance, and show how kernel operations relate to the utilities that are
familiar to Unix programmers and Users.
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.
The MINI2440 is an effecient ARM9 development board with a comprehensive price, it characterizes simple method and high performance-price ratio. Based on the Samsung S3C2440 microprocessor, it embodies professional stable CPU core power source chip and reset chip to ensure the stability of the system operation. The PCB on the MINI2440 board is designed to be 4-layers board, adopting the ENIG technology and professional equal-length wiring to ensure the completeness of the signals of the key signal wires and manufactured and released under stringent quality control plans. With the help of this detailed manual, Users are supposed to become proficient in the development process of embedded Linux and WinCE operating system, they are supposed to get the foundation, so long as they have obtained the basic and necessary knowledge about the C language, in two weeks.
We are providing the best information available to us as at date of writing and intend to update it at
frequent intervals as things change and/or more information becomes available. However we intend this
Q&A as a guide only and recommend that Users obtain specific information to determine applicability to
their specific requirements. (This is another way of saying that we can t be held liable or responsible for
the content.)
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.
This manual is an introduction to the Keil Software development tools for the
8051 family of microcontrollers. It introduces new Users and interested readers
to our products.
While faster processors, larger memory, and powerful graphics are fundamental requirements for workstations, Users
are also demanding a low-cost, solution-based approach wrapped around a standards-based technology. The Sun UltraTM
20 Workstation, which leverages the AMD OpteronTM processor with Direct Connect Architecture based on AMD64
technology, provides multiple operating system choices and leading nVidia graphics, delivers a platform that offers
flexibility and performance in a cost-effective package with solutions to benefit customers across the board.
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
