![]() Ownership of a data path is more like a toll road than public highways. Someone paid for all these cell towers, satellites, microwaves, copper wire, and fiber optic cable installed, so somebody owns the paths. That part has to do with the way the owner of the path sells it. Now, just because you have a cable or wireless connection that is capable of transmitting data really fast doesn't mean you always get fast data transmission. Fiber-optic cable is often used in networks because it has the highest data transmission rate possible. Copper wire is used in Ethernet, telephone, and cable TV connections. Wired networks are often copper wire or fiber-optic cable. Another example is satellite TV which sends broadcasts to your home using a satellite network. For areas with no cable or phone wires, satellites are often used for data connections. Often it's easier to install a wireless microwave or laser connection to connect two buildings to each other rather than running wire or cable. I already mentioned wireless cellular connections, but in addition to the cellular networks, there are microwave, laser, and satellite types of wireless connections. So let's talk about the types of materials that are used for connections. The speed of a data connection depends on both what it's made out of (the material used for the connection), and the speed allowed by the owner of the connection to the users. What Types of Physical Connections Are Used? How fast data moves from one point to another is measured in bits per second, and connections are usually fast enough now that the million is added on, making it Megabits per second. The paths that carry data communications connect to points where data can be sent in different directions, just like when two freeways intersect, at a stoplight, or a traffic circle. Since the Internet is a shared "highway," it's necessary to have on and off-ramps, only these are data connections made with wires, cables, and antennas, not roads. For your information, any connection that isn't wireless is sometimes called a landline. The more capacity the road has for traffic, the faster vehicles can move from one point to another.ĭata moves across both wired and wireless "highways." Our smartphones use wireless cellular connections to reach a cell tower, then the tower uses a cable to transmit data over wired, or what are called "landline" connections. Some roads have more capacity than others, with more lanes, higher speed limits, and even express lanes. The Internet is a shared highway, just like our roads and freeways. The bits that travel on the Internet are similar to our vehicle analogy. How fast single-vehicle travel on the road depends on the capacity of the road (bandwidth) and how many other vehicles are using the same road. If you think of freeways, there are different sizes, shapes, and capacities. And in many ways, moving digital data is similar to how vehicles move on the road. You might have heard of the phrase "the digital highway," which is often used to describe the movement of data across the Internet. Using email and the Web all involve moving data from one location to another, so the speed at which data can be moved is important. Moving bits from one point to another is important as more people use digital devices. The higher the Megabits per second, the faster data moves from one point to another.Ī bit is a single unit of data used in digital computing. Mbps is commonly used to describe how fast a connection is from a computer, smartphone, tablet, or network to the Internet. Bandwidth is measured in bits per second and one Megabit per second is 1,000,000 bits per second. The capacity of a connection is referred to as it's bandwidth. Megabits per second (Mbps) is used to describe the speed at which digital data travels from one point to another.
