Chapter Two: Internet Services in Windows Goal The main goal of this chapter is to give you a working knowledge of how to operate the Windows operating system (OS), to receive and send electronic mail (e-mail), and to access the internet. In addition, the concepts of internet, internet services, and internet elements (such as servers, routers, hosts, ISPs, clients, NSPs) are defined and discussed. Netscape, Explorer, and Mozilla are mentioned as browsers or clients to access internet services, particularly web pages. The main reason for introducing this material early in the book is because you will have to use both the internet and e-mail frequently in order to successfully complete the course. In this chapter, you will learn to set up Windows XP and Mac OS for remote connection to the ucdavis.edu or other domains. I describe the internet and its services, and I explain the more common protocols, including TCP/IP and IMAP, POP, and SMTP for e-mail. Detailed instructions are given for the use of e-mail as one of the internet services. Introduction to Windows Windows is the name used to refer in general to the various operating systems produced by Microsoft ® . The name, of course, refers to the graphical user interface (GUI , pronounced ―gooey‖) in which the screen can display several areas (windows), each dealing with a separate aspect of what the computer and the user are doing. It is likely that you have no experience with anything but ―windowed‖ operating systems, but until 1984 GUIs and windows did not exist in commercial operating systems. At that time, computers had been around for a while, but the concept of a GUI was revolutionary. As you will learn in the next chapter, Microsoft was not the company where the concept of windows was first developed; it was first conceived at Xerox and first developed into a full commercial GUI by Apple. Today windows are used in most if not all operating systems, including Mac OS, Unix, and Linux. Windows has had many ―flavors‖ starting with Windows 3, Windows 95, Windows 98, Windows 2000, etc. –– within each name there are even several editions. For example, you can have XP Home, XP Professional, XP Media Center, XP Tablet, and XP 64-Bit Edition! The latest version is Vista. Windows is organized as a desktop where you have icons and open windows. Icons represent files or folders. In general, files can be documents that contain information usable by programs executable files), configurations, scripts, etc. (Table 2.1).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
