Most companies rely on the internet and email to share data between staff members. This is convenient in large companies that are spread out over the world. Data cabling helps keep everything connected.
While many people do not think of data cables having electricity running through them, they do have a small amount going through them because this is what carries the signal from one place to another. This is very important. The size of the cable can determine how quickly that this happens and what kind of files can be transferred from one place to another.
Phone lines were one of the first types of data cables. While most homes will have one simple cable running into their home, a business may have an entire phone system that connects the entire company. Calls can be transferred from one person to another without making the customer call back.
For residential customers, another type of data cable will include their television services. Some of them will be run to a wire that runs all through the entire neighborhood. Others will be hooked to a satellite dish and only ran into the home but can be connected to several rooms of the home.
