30.1 Introduction

In this chapter we describe additional TCP/IP applications that many implementations support. Some are simple and easy to cover completely (Finger and Whois), while another is complex (the X Window System). We provide only a brief overview of this complex application, focusing on its use of the TCP/IP protocols.

Additionally we provide an overview of some Internet resource discovery tools. These are tools to help us navigate our way around the Internet, searching for items whose location and exact name we don't know.
