- The Internet is the largest wide-area network that is made up of a bunch of smaller computer networks. Everything you find online is brought to you by the Internet. Whether it's web pages, email, social networking sites, or games, the Internet provides it all for you. In 2011, more than 2 billion were using the Internet regularly. It makes it hard to believe that in the eighties, Internet was just being introduced, and was a very new and uncommon feature.
- Protocols control or enable the connection, communication, and data transfer between two computing endpoints. They were established as rules for the computer to follow. It also can be called network protocols, that do the same thing, but within a computer network. This helps communication between machines be efficient and orderly. The first network protocol was on the ARPANET network in 1969.
- DNS stands for Domain Name Service. It translates domain names into IP addresses that locates the computer. Without it, there would be no Internet communication. It is commonly compared to a phone book because it takes a host name and returns an IP address, or the other way around. Each part of the Internet has DNS servers.
- ISP stands for Internet Service Provider. They connect through routers that then connect with computer networks on the Internet. Data travels from router to router to reach a specified place from the user. ISP's came along in the late 1980's. The Internet didn't start evolving until the 80's, and service providers were at a demand at the end of the decade.
- The PING utility can be used to check network connection. It sends test packets over the Internet and evaluates if that particular machine receives them. Pinging your computer can tell you whether your connection is working. A firewall protects your machine from Internet threats. It can be software or hardware based.
Connecting to the Internet Summary
The Internet is made up of a bunch of smaller computer networks. It is many networks connecting together to create this one wide-area network. The Internet is the largest network, and the smallest one is individuals who use their personal computers at home connected to the Internet. Those small networks are run by that person's ISP or Internet Service Provider. Backbones and routers handle all the high level data and help it get to it's destination. Different networks use these parts to communicate freely with each other. The Internet is basically a whole bunch of connections in a network.
An Internet Service Provider, or ISP helps companies or individuals get a sustain a wireless connection. They often also let the customer choose the types of services given to them to best suit their needs. Consumer connections are made by DSL's, or digital subscriber lines. They're the most common on cable Internet. Any connection can be made through copper wire telephone lines, cable TV lines, or fiber-optic lines.
The simplest way to connect to the Internet is to get a modem and ISP for your machine, plug your computer into the modem and turn it on. If you have a broadband connection, you don't need an ISP every time you use the computer, the connection stays on. Cable lines work the same way, in which they're "always on." You can also connect with Ethernet plug connected to a web server. You can also connect wirelessly, and your modem connects to the Internet's hub to give you connection. Your ISP gives your computer a unique IP address when it's connected.
