A patch cable is an electrical or optical cable used to connect one electronic or optical device to another for signal routing. Devices of different types (e.g. a switch connected to a computer, or a switch connected to a router) are connected with patch cables.
Left: 20-way grey ribbon cable with wire for pin 1 marked red, insulation partly stripped. Right: 16-way rainbow ribbon with IDC connector. IDC D-sub connectors DE-9 (male) and DA-15 (female) Twisted ribbon cable used for Parallel SCSI connections. A ribbon cable is a cable with many conducting wires running parallel to each other on the same ...
Computer ports in common use cover a wide variety of shapes such as round (PS/2, etc.), rectangular (FireWire, etc.), square (Telephone plug), trapezoidal (D-Sub — the old printer port was a DB-25), etc. There is some standardization to physical properties and function.
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
RG-62 is a 93 Ω coaxial cable originally used in mainframe computer networks in the 1970s and early 1980s (it was the cable used to connect IBM 3270 terminals to IBM 3274/3174 terminal cluster controllers). Later, some manufacturers of LAN equipment, such as Datapoint for ARCNET, adopted RG-62 as their coaxial cable standard. The cable has the ...

IP phone systems can run the telephone and the computer on the same wires, eliminating the need for separate phone wiring. Regardless of copper cable type (Cat 5e/6/6A), the maximum distance is 90 m for the permanent link installation, plus an allowance for a combined 10 m of patch cords at the ends.
Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include copper coaxial cable , copper twisted pair cables and fiber-optic cables used in wired networks, and radio waves used in wireless data communications networks.
