Unshielded Cables: This cable is usually referred to as unshielded twisted pair cable (UTP) where individual wire pairs are simply wrapped in a foil, without any additional layer of protection. Unshielded cables are ideal for office environments, which experience less traffic.

Cat 6, an unshielded twisted-pair (UTP) design, emerged as an advancement of the UTP Cat 5e, which was formalized in 2001. The design of Cat 6 required more stringent precision in manufacturing, and this enabled reduced noise and crosstalk, allowing improved performance.

Hard disk, also called hard disk drive or hard drive, magnetic storage medium for a computer. Hard disks are flat circular plates made of aluminum or glass and coated with a magnetic material. Hard disks for personal computers can store terabytes (trillions of bytes) of information.

An external hard drive is a portable storage device that can be attached to a computer through a USB or FireWire connection, or wirelessly. External hard drives typically have high storage capacities and are often used to back up computers or serve as a network drive.
