Book is for everyone who uses Windows XP Home Edition and Windows XP Professional. You might already have Windows XP installed on your computer, or you might be considering upgrading a Windows Me, Windows 98, or Windows 2000 system to Windows XP. You might have a lot of experience with other computer systems, or Windows XP may be your first exposure to computing. Your computer might be the only one in your home or office, or it may be one of many on a local area network. You probably have a modem or network card, although Windows works perfectly well without either. Chances are, your computer is connected to the Internet, or will be soon. If your computer is connected to a large network, we don"t expect you to be the network administrator, but if you"re in a small office with two or three computers, we tell you how to set up a small, usable Windows network. If you have a modem, we discuss in detail what"s involved in getting connected to the Internet, because Windows XP includes all the software you need to use the Internet. >note If you are the network administrator of a domain-based local area network, or if you need to know about the security and networking options for large networks, consider getting Windows .NET Server: The Complete Reference (by Kathy Ivens, published by Osborne/McGraw-Hill). It"s the companion volume to this book for information technology staff members who support Windows XP servers and networked workstations .
