Glossary of Terms for Computer Cabling
- Computer Cabling: The physical infrastructure of cables and connectors used to establish communication between devices in a computer network.
- Cat 5 (Category 5): A type of twisted pair cabling commonly used for Ethernet networks. It supports data transfer speeds up to 100 Mbps.
- Cat 5e (Category 5e): An enhanced version of Cat 5 cabling, supporting higher data transfer rates and reduced crosstalk.
- Cat 6 (Category 6): An advanced twisted pair cabling designed to handle data transfer speeds of up to 1 Gbps.
- Cat 6a (Category 6a): An improved version of Cat 6 cabling, capable of supporting data rates up to 10 Gbps.
- Cat 7a (Category 7a): A high-performance twisted pair cabling, capable of handling data transfer rates up to 10 Gbps at 100 meters.
- Fiber Optics: A technology that uses thin strands of glass or plastic to transmit data as pulses of light, enabling high-speed and long-distance communication.
- Ethernet Cable: A type of computer cabling used to connect devices to a network, such as computers, routers, switches, and printers.
- Patch Cable: A short Ethernet cable used to connect devices within a local area network (LAN) or to connect network equipment to a wall outlet.
- Crossover Cable: A special type of Ethernet cable used to directly connect two similar devices, such as two computers or two switches, without the need for a network hub or switch.
- RJ-45 Connector: The standard connector used for Ethernet cables, allowing for easy connection and disconnection of devices.
- Twisted Pair: A type of cabling in which two conductors are twisted together to reduce electromagnetic interference and crosstalk.
- Coaxial Cable: A type of cable with a central conductor surrounded by a layer of insulation and a braided metal shield, used for high-frequency transmission.
- Plenum Cable: A type of cable designed for use in plenum spaces, such as air ducts, where fire safety requirements are more stringent.
- Structured Cabling: A standardized approach to designing and installing a cabling system to support various communication technologies within a building or campus.
- Termination: The process of attaching connectors to the ends of cables to facilitate connection to network devices.
- Patch Panel: A device used to organize and manage multiple network connections, typically installed in a network rack or cabinet.
- UTP (Unshielded Twisted Pair): A type of twisted pair cabling without additional shielding, commonly used for Ethernet networks.
- STP (Shielded Twisted Pair): A type of twisted pair cabling with additional shielding to reduce electromagnetic interference.
- Network Rack: A structure used to mount and organize networking equipment, including servers, switches, and patch panels.
- TIA/EIA: The Telecommunications Industry Association/Electronic Industries Alliance, responsible for developing standards for telecommunications and computer cabling.
- MDF (Main Distribution Frame): A centralized point in a building or data center where telecommunication and computer network cables are terminated and connected.
- IDF (Intermediate Distribution Frame): A distribution point within a building where network cables from various locations are terminated and connected to the MDF.
- Backbone Cabling: The high-capacity cabling that connects MDFs and IDFs, providing the main communication path between different network segments.
- Cable Management: The practice of organizing and securing cables to maintain a neat and efficient cabling system.
- Bundling: The process of grouping multiple cables together using ties or Velcro straps to reduce clutter and enhance cable management.
- Cable Tester: A device used to verify the integrity and connectivity of network cables, ensuring proper data transmission.
- Jumper Cable: A short, pre-terminated cable used to make temporary connections within a patch panel or between network devices.
- Power over Ethernet (PoE): A technology that allows power and data to be transmitted over Ethernet cables, simplifying the deployment of network devices.
- Cross-Connect: The process of connecting wires from one cable to another, typically used in telecommunications and structured cabling systems.
- Pulling Cable: The process of installing cabling by pulling it through conduit, raceways, or cable trays.
- Patch Cord: A short, pre-terminated cable used to connect network devices to a patch panel or wall outlet.
- Jacket: The outer protective covering of a cable, providing mechanical protection and resistance to environmental factors.
- Drop Cable: The cable that runs from the telecommunications service provider’s access point to a building or subscriber’s location.
- Horizontal Cabling: The cabling that extends from the telecommunications outlet to the network equipment, typically located in the same building.
Remember to regularly maintain and upgrade your computer network cabling to ensure optimal performance and reliability in your communication infrastructure.
