調制解調器是一種使計算機通過電話線路通信的設備。使用調制解調器，您可以向另一臺配有調制解調器的計算機發送數據。這使您可以從全球網 (World Wide Web) (正如您現在所做的一樣) 中下載信息、發送和接收電子郵件 (e-mail) 及與遠程對手玩計算機游戲。一些調制解調器還能發送和接收傳真及語音電話呼叫。 不同的調制解調器通信速率也不相同。許多新型的調制解調器能以 33.6 kbps 的速率發送和接收數據；以 14.4 kbps 的速率發送和接收傳真。一些調制解調器能以高達 56 kbps 的速率從 Internet 服務供應商處 (ISP) 下載信息。

The Linux kernel is one of the most interesting yet least understood open-source projects. It is also a basis for developing new kernel code. That is why Sams is excited to bring you the latest Linux kernel development information from a Novell insider in the second edition of Linux Kernel Development. This authoritative, practical guide will help you better understand the Linux kernel through updated coverage of all the major subsystems, new features associated with Linux 2.6 kernel and insider information on not-yet-released developments. You ll be able to take an in-depth look at Linux kernel from both a theoretical and an applied perspective as you cover a wide range of topics, including algorithms, system call interface, paging strategies and kernel synchronization. Get the top information right from the source in Linux Kernel Development.

The Art of C++ by Herbert Schildt ISBN:0072255129 McGraw-Hill/Osborne © 2004 The author of this text applies C++ to a wide variety of high-powered, practical applications, each focusing on a different aspect of the language. Examples range from a garbage collector subsystem and a thread control panel to AI-based searches and more.

THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make reading easier for those who do not read all sections. This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.
