 Ethernet cables (such as Cat5e, Cat6, Cat6a, and Cat7) are used to transmit data between network devices. They consist of twisted pairs of copper wires to reduce interference. 

 Fiber optic cables use light to transmit data over long distances with high speed and low latency. Common types include single-mode and multi-mode fibers. 

 Patch panels are used in data centers and structured cabling systems to organize and manage network cables. 

  Racks and cabinets are used to house networking equipment like switches, routers, patch panels, and servers in an organized manner.
