Sample text

When I send the file to my editor at Cisco Press, she uses the same program to open the file and edit the chapter. So, you can think of our computers as speaking the same language. In this case, both of our computers understand files formatted for use with Microsoft Word, which is a word processing program. It is relatively easy to think of a file that contains the text for this chapter. However, at the same time, the file is really just a bunch of bytes, with each byte containing 8 bits. It's a little like when you put a file folder in a real file cabinet, you might be thinking that you're doing simply thatstoring one file in a cabinet.

The term download typically refers to the process of retrieving a file that someone else has and making a copy on your computer. So, downloading would technically be the same thing as file transfer. ) One rather mundane type of file downloading is when you decide to update the software on a networking device. The vendor that sells the device allows you to download new software via the Internet. The vendors are happy to have you download the files; that's a lot cheaper for them than mailing the software to you using the postal service.

This section covers a few of the more popular applications, including web browsing, electronic mail (e-mail), file downloading, and file transferring. Web Browsing Almost everyone reading this book has probably used a web browser. A web browser allows you to sit at one computer and display information that resides in a web server somewhere on the Internet. The information can be in many forms, including simple text, graphics images, animation, video streams, and audio clips. Even if you've not heard of the term web browser, you might have heard of Internet Explorer or Netscape, which are the names of two of the more popular web browsers on the market today.
