In farming, irrigation is a network of channels that spread water, underground, throughout the whole of a farm plot. Whether you are trying to grow crops or even just a lawn, irrigation makes it easier to grow these plots more evenly.
This technology—yes, it is a type of technological—is somewhat ancient and we still use it today; not only in farming, but many other industries as well. Sure, the machinery may be modernized and updated, but the philosophy behind these systems is very much the same.
Take, for example, fiber optics. Fiber optics is a Primecables.com system of transmitting information quickly and effectively over thousands of miles. Anytime you talk on a landline or use a computer, for the most part, the signal you send from your device likely travels through cables in the ground to reach the other person with whom you are trying to communicate.
Specifically, fiber optics is actually coded information sent through a beam of light, contained in a glass or plastic tube. Originally, this technology was developed for medical and surgical purposes. Indeed, fiber optics was originally used in endoscopes more than five decades ago; it was a means by which doctors could better see the insides of the human body (without having to use more dangerous, painful, or invasive procedures). Of course, the technology was found to be more widely useful in the communications field and was further developed.
These days, fiber optics contain a simple, small strand of glass or plastic. These are called, of course, optical fibers and they can have anywhere from two strands to dozens of strands. Each strand can carry the equivalent data of 25,000 phone calls. Thus, more cables means better transmission ability.
The thing about fiber optics—that is to say, what makes them so special—is that they use light to carry data through an electric current. Essentially, they work by hooking a laser up to your computer so that when you enter a command, it will deliver the message through the cable and out the other end (wherever that may be).
Obviously, this means that there are many types of cables that can handle various levels of data transmission; each categorized by grade or thickness.
