Data cables are wires that connect computers on a network. Unless the computer is wireless, it requires a data cable to access the Internet and the local network. Data cables have several types, which allow different speeds of communication.
Significance
Without data cables, computers would not be able to communicate. Even wireless networks have some kind of data cable connections in the infrastructure.
Features
A data cable is composed of the inner wires, a thick cover that encases the wires and an RJ45 connector at the end. The RJ45 connector inserts into the computer.
Types
Ethernet cables are the most popular types of data cables. However, other types of cables include coax, fiber and ribbon.
Identification
Data cables look similar to voice cables. Most network administrators label each type to avoid confusion. However, data cables have eight wires visible in the RJ45 jack. Voice cables typically have a smaller connector and only four wires.
Considerations
Data cables are protected by an outer shield, but devices like telephones and microwaves can corrupt data communication. When wiring a home or office with data cables, keep them clear from other devices that emit strong signals.
