Today's Featured Computer Term: DOS
DOS is an acronym for disk operating system. The term DOS can refer to any operating system, but it is most often used as a shorthand for MS-DOS (Microsoft disk operating system). Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers.
The operating system is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.

Today's Topic: Are the Internet and the World Wide Web the Same Thing?
There is a difference between the Internet and the World Wide Web. It's actually very simple. The Internet is a network connecting millions of computers that all work together to share information. The computer you are using to read this information, the computer being used to send this information, and all the computers in between are hosts of the Internet.
Only with this global network of computers in place is the World Wide Web able to exist and flourish.
The Web is a system of Internet servers that supports a collection of documents that are written and formatted using the same type of programming language. The documents are formatted in a language called HTML (HyperText Markup Language) that supports links to other documents, as well as graphics, audio, and video files. This means you can jump from one document to another simply by clicking links.
These documents, or Web Sites, are able to be retrieved and viewed when you enter a Web Site address in your browser, because you are actually sending a Hypertext Transfer Protocol (HTTP) command to the Web server directing it to find and transmit the requested Web page. That's the http:// part of the Web Site address. In other words, because all of the Web Sites that make up the World Wide Web are formatted using the same programming language, and because all browsers know how to request these specially formatted Web Site files, we are able to browse, or surf, the Web!
Therefore, the Internet and the World Wide Web are not the same. Could the Web exist without the Internet? No. Could the Internet exist without the Web? Yes, but it wouldn't be nearly as exciting.

Progressive Learning Series: Take A Chance With Refills
Ink cartridge refill kits can save you a lot of money and the reviews are saying that they work fairly well if the kit comes with high-quality ink. And, even if the ink quality is poor, it shouldn't damage your printer. The worst that could happen is having to pay again for a new print cartridge if the refilled one over sprays or clogs.

Today's Featured Website: The Oyez Project
The Oyez Project is a Northwestern University project that provides information about important Supreme Court decisions in easy-to-understand summaries that are linked to the complete text of the justices' opinions.
You can hear as well as read the court's proceedings, since the court began taping its sessions more than 40 years ago.
