Extracts from this document...


What is the internet? The internet can be defined as a "network of networks". A single network consists of two or more computers that are connected to share information. The internet connects thousands of these networks so all of the information can be exchanged worldwide. Connections are typically made through a modem, a device that allows computers to exchange and transmit information through telephone lines. A modem takes digital information and passes it through a series of steps to convert it to analogue signals or sound waves that can be passed over a telephone line. The process is reversed when the modem converts information coming in from the phone line. Modems transfer the information at a rate of bits per second (bps). A modem with high-speed capabilities will assure a faster connection on the Internet. Once the computer is connected to the internet, it is called a local site, and the computers communicating with the local site are called the remote sites. Many remote sites are hosted by organizations called domains. Domains are designations that indicate the type of web site. For example: * .gov - government * .edu - educational * .com - commercial providers. * .org - non-profit organizations. * .co.uk - company in the United Kingdom. ...read more.
