UNIT 19.1 Internet Basics for Biologists

Before embarking on any practical discussion of computational methods in solving biological problems, it is necessary to lay the common groundwork that will enable users to both access and implement the algorithms and tools discussed in this book. This unit begins with a review of the Internet and its terminology, and also discusses major classes of Internet protocols, without becoming overly engaged in the engineering minutiae underlying these protocols. This unit also discusses matters of connectivity, ranging from simple modem connections to digital subscriber lines (DSL). Finally, one of the most common problems that has arisen with the proliferation of Web pages throughout the world is addressed, i.e., finding useful information on the World Wide Web.
