A modem is an electronic device that converts the digital signals your computer sends to the phone connection to analog signals and vice versa. Originally, it was a program for observing Web pages. All the newer browsers now offer an e-mail client and a newsreader. The domain name is that part of an Internet address that identifies the owner of that address. A Web site is a series of pages on the Internet where an individual, a business, an academic institution etc., displays their information.
Surfers have access to the entire site via hyper-links.
The Hypertext Markup Language is the language used to write Web pages. Validation is a process that guarantees that HTML coding, used to write Web pages, follow the prescribed syntax. The home page is that particular page to which the site's URL takes the browser. A hyper-link is a highlighted section of text or an image. The hyper-link will take you somewhere else within the page, within the site or someplace else in the world.
