What is a Web?
The World Wide Web (www) is the most popular extension of the Internet, the global electronic communication network; Information is presented on ‘pages ‘ made accessible through program called browsers. Common browsers include Firefox, Netscape, Internet Explorer, Mosaic and Lynx. The information provided reflects the activities, interests and frequently personalities of those who host the pages -from recreation and research areas through to full blown publication, art galleries and sound studios. Web pages are usually designed in such a way that the reader can effortlessly follow ‘links’ to related subjects, information or files.

If you have just accessed pages then a review of that page might come from your disk cache; this is why you will see your disk light trashing so much when you do any viewing of images. . .it is saving all the images, in case a particular image is called up again. This is much faster than downloading the images again, but would wear the hard drive much faster. If you listen closely for hard drive head thrashing, you know what we mean.Being cautious with what you download will not only preserve the bandwidth and access for everyone else, but will also preserve a hard drive a lot longer, presuming it dies from usage as opposed to those that are dropped or hit by lightning or kill motors.You can do your part to reduce this wastage, by optimizing those pictures you do include on your Web Pages. . .jpg files are easy to optimize.
