You find out about domain name selection, name generators, domain verification, and domain registration.

Understanding How to Get Your Site Online Before you can make a new website available on the Internet, it must first be assigned its own special web address,COPYRIGHTED which is commonly referred to MATERIALas the domain name. The process of acquiring a domain name can be a fun adventure and only requires a little bit of work. To start with, someone needs to think of a good name for the site and then check to see whether that name is available for use or has already been taken. If the desired name is available, the name needs to be registered, and that can be done either through a domain registrar or a host provider.

    United Nations Conference on Trade and Development Use of the Internet for Efficient International Trade Guide for SME Managers Prepared by the UNCTAD secretariat United Nations New York and Geneva, 2004 Chapter 1 UNDERSTANDING THE INTERNET BEYOND THE BASICS 1. Objectives and organization of the chapter The goal of this chapter is to explain and illustrate the major technical and commercial features of the Internet, which have potential impacts on businesses in developing countries. This chapter is not an introduction to the Internet. It is assumed that readers have a basic understanding of the Internet and are reasonably proficient at using it. This chapter lays the foundations upon which chapter 2 (Introduction to e-business) and chapter 3 (Internet for international trade) will build. In this chapter we start by bringing to the fore some key characteristics of the Internet (section 3). The subsequent sections cover services which are part of the Internet; these services are the web (sections 4 to 7), e-mail (section 8), file transfer protocol (section 9), discussion groups (section 10), IP telephony (section 11) and real time communication tools (section 12). Last but not least, Internet-based searches ( section 13) deals with several of the above-mentioned services of the Internet. 2. Introduction The Internet is a network of several hundred million computers which are interconnected and located all over our planet. It is as simple as that. Technically speaking, the Internet is not an impressive innovation. What is spectacular is the fact that, for the first time in history, there is a truly global and very dense computer network.
