How does cable internet work? How does a computer or router become a connection point between a modem and a television? That is simple, really. Picture yourself sitting at your desk in front of a computer, or a laptop on your lap. Now picture yourself surfing the internet through a set of coaxial cables connected to a television. This is all possible thanks to the cables that connect your computer and your television, called the cable internet service providers.
The process is actually quite straightforward. In order to understand how does cable internet work, it’s first important to understand how your computer and router interact with each other. Your computer and router are essentially communicating with each other over a network of physical connections called inter-network connections. What this means is that they are able to send and receive data at the speed of light, which in turn means that the data can be sent at the rate of downloads. This information travels from one computer to the next until it reaches the end user – you.
This is the basic information that your computer is communicating in a nutshell. When we talk about how does cable internet work? The answer is pretty straightforward, at least in the present time. Most people understand that their computer and router are communicating through a network of physical cables, but just in case you didn’t know, the network has three layers:
The two layers of the network are separated by physical means, and there are various ways to get between them. It would be a very boring article if I didn’t tell you what each layer is. The physical layer is composed of four components: optical fibers, copper wires, telephone lines, and digital channels. Let’s take a closer look at these four components. In order for information to travel through these physical mediums, it must be in a consistent state. For instance, information that is sent over fiber optic cables goes from source to receiver in an optically clear state, while data that is sent through telephone lines goes from transmitter to receiver via conductors that are connected to the telephone line.
This brings us to the next component: coaxial cables. These are also called optical cables, because they carry information using light rather than physical means. This technology was first used in World War II to transmit information between defense sites and factories. Today, people use coaxial cables to connect computer and phone networks, as well as providing broadband internet service. The physical design of coaxial cables ensures that information travels faster over a given distance; this results in much higher bandwidth usage by consumers.
Finally, there is the last component: satellite. You probably already know that satellite delivers television programming directly to your home; the same concept is applied to cable internet access. Basically, satellites send out radio signals in the form of electromagnetic radiation. These signals are received by receivers on the ends of cable internet connections. Those receivers convert the signals into digital information that can be sent over long distances.
There are a few different ways that satellite internet works. It has the same basic principle of long-distance communication with the added benefit of high-speed internet services. A satellite internet connection works best when it is used in conjunction with another type of wireless connection, such as wireless telephone or Wi-Fi. Satellite providers generally offer services for a monthly rate, but many people can fit two or more wireless devices into their household for just one low monthly rate. Of course, each household has to be equipped with at least one high-speed connection.
All of the aforementioned components are present in broadband internet access. The difference is that it requires a broadband internet access provider to provide the coaxial cable, telephone lines, and computer hardware to transmit the signals wirelessly to the receiver. This is why it is important to obtain a dedicated high-speed connection in order to take advantage of the service. However, if you already have a cable internet connection at home, you can always look into satellite internet options.
