How the Internet Is Structured

The definition of Internet is a compression of ‘interconnected networks’ and, indeed, the Internet is a huge global collection of linked networks. The networks that make up the world wide web can range in size from tiny (just two or three linked computers) to massive (thousands of interlinked machines). Verizon Fios Double Play for $49.99 ymmv

A great Internet service agency (ISP) is a telecommunications business that gives Internet-related services such as access to the Internet, domain registration, website hosting, and so on. ISPs permit you to hook up online. 

When you use your computer to access the world wide web from your home you most likely hook up to the ISP via a modem and a local telephone number or by using a dedicated excessive line. As you hook up to your ISP you feel part of their network, that enables you to gain access to the Internet.

The pcs in the office where you work are likely to be linked jointly into a network known as a neighborhood network (LAN). This permits the computers in the office to communicate with each other. The LAN is most probably linked to an ISP which interconnection permits you to gain access to the Internet from your office computer.

Either way, your home PC or your office LAN becomes part of the ISP’s network. The ISP will link subsequently to a larger network to be part of that network. That network will be linked to other larger systems to create a marketing communications system that spans the complete globe.

Thus the Net is nothing more than a network of sites. These networks hook up pcs by using a wide variety of technologies, including conventional and high-speed telephone lines, fibre-optic cables, microwave links, cordless technologies and satellite sales and marketing communications.


The networks are linked using routers. A router is a specific computer that directs traffic on the Internet. While the Internet contains hundreds of thousands of smaller networks linked together, the use of routers is totally necessary.

When you want to visit a specific website, you type the address of the site into the web browser. The address would go to the nearest router and the router makes a decision where that site is on the net.

The router also determines the most efficient path through all the networks to succeed in this destination. This determination is based on the traffic in several parts of the Internet and the available connections.

Higher-level sites

The networks in a specific region may be grouped with each other into a mid-level network. Or they may be linked in a wide-area network (WAN). A WAN covers a larger physical area compared to a mid-level network. If the website you are looking for is within the same local network or WAN, the router will send it directly to its vacation spot.

Yet , if the website you are looking for is at another part of the Internet, the router will send your demand to a network get point (NAP). NAPs hook up high-level networks, ie they allow access to Net backbones.

The Internet backbones are an accumulation networks that link will pleasure your clit like no other vibrator super-computers. The backbones contain fibre optic shoe lines (aka OC for optical carrier). The speediest OCs can transit 2. 488 gigabits per second!

There are numerous high-capacity backbones around the world, all connected with each other at various NAPs. They will permit everyone, no subject where they are, to communicate freely with everyone else on this planet.


Since you can see the Internet is a veritable jumble of interconnected systems. These networks are connected by using a variety of communication technologies that vary from very slow to ultra-fast. And, given the way that routers decide the most effective route, your data may circumnavigate the world before reaching their destination.

For example, a request from a web surfer in Dublin to view a site hosted in Birmingham seldom travels straight from Dublin to London; chances are to be sent with the Americas should this be the speediest path (as measured in milliseconds).

The web that the further data has to travel, the more it dips or fades. Repeaters are pieces of hardware that amplify or refresh the stream of data. Enhancing the info signals permits the data to circumnavigate the globe yet arrive undamaged at its final vacation spot.
