- The Internet is an electronic communications network that allows computers all over the world to be connected.
- A computer has to be equipped with a device called a modem before it can be connected to a telephone or cable TV line. Following are the most common connection types and each requires a different modem type.
- An ISP (Internet Service Provider) is required to complete a connection to the Internet. For DSL connections the telephone company is usually the ISP and for cable TV connections the cable company is the ISP. For dial-up connections the ISP is usually an independent company like NetZero.
- Website pages have to be stored on an Internet server so then can be accessed by other computers. A server is basically a computer that has a lot of disk capacity and the required Internet interface software. Hosting companies like IX Webhosting have large numbers of servers and rent space for storage of website pages.
- The telephone company is able to find another telephone because each telephone has a unique telephone number. Similar numbers called IP (Internet Protocol) numbers are used by the Internet. Every computer and server connected to the Internet has a unique IP number/address. Websites also have unique IP numbers so they can be found on the host server. Websites have a domain name (e.g. http://www.doawebsite.com) because names are easier to remember but it is the website IP number that is used by the Internet to find a website page.
NOTE: You can access a website by using the IP number instead of the domain name. For example use http://66.116.147.131 to access www.doawebsite.
