Without a cable connecting your sound card to your computer speakers you won't hear sound; without a USB cable connecting your external hard drive to the computer, you won't be able to access files on the hard drive. Without a power cable connected from your computer monitor's power source to an electrical outlet in a wall, you won't be able to power on your computer monitor. Cables and connectors are integral components for the proper flow of information and data internally and externally within the computer. Without all of the required cables and connectors, the personal computer is just another big piece of metal.
Cables allow your computer to do fun things such as produce sound, print documents, and relaying output to your computer's monitor. Without connectors, cables would cease to function. A connector is a way cables can perform their duties.
The only type of technology that does not require any kind of cabling is wireless network technology. Wireless technology permits for the transmission of data through radio wave signals, invisible to the human eye. Wireless is still predominately used for networking technologies, but other technologies such as keyboards, mice, and computer based remote controls, have also employed wireless communications in the form of infrared protocols.
What Internal Computer Cables Do
Internal computer cables control the flow of information to components internally within the computer. These cables are not visible until you open the metal case of the computer tower. Every component within the computer must be connected to the computer's motherboard to serve a purpose.
Most cables are different in color and functionality and are based on the type of component being connected. This area will attempt to explain the various types of PC cables and connectors through illustrated guides that pin point what a cable does and what each pin on a connector is for.
