| Acronym | Term | Definition |
|---|---|---|
| d(⌒ー⌒) | 110 block | type of punchdown block designed to terminate Cat 5 or better twisted-pair wires and typically used to handle data connections rather than telephone connections. The numeral 110 refers to the model number of the earliest blocks. |
| d(⌒ー⌒) | 66 block | A type of punchdown block designed to terminate telephone connections. The numeral 66 refers to the model number of the earliest blocks. |
| d(⌒ー⌒) | crosstalk | type of interference caused by signals traveling on nearby wire pairs infringing on another pair’s signal. |
| demarc | demarcation point | The point of division between a telecommunications service carrier’s network and a building’s internal network. |
| EIA | Electronic Industries Alliance | Dissolved trade organization that sets standards for electronic equipment and lobbies for legislation in the growth of the computer and electronics industries in the US. Taken over by ECA (Electronic Components, Assemblies, Equipment & Supplies Assoc.) |
| EMI | Electromagnetic interference | A type of interference that can be caused by motors, power lines, televisions, copiers, fluorescent lights, or other sources of electrical activity. |
| d(⌒ー⌒) | entrance facility | The location where an incoming network service (whether phone, Internet, or long distance service) enters a building and connects with the building’s backbone cabling. |
| d(⌒ー⌒) | fiber-optic cable | A form of cable that contains one or several glass or plastic fibers in its core. Data is transmitted via a pulsing light sent from a laser or LED (light-emitting diode) through the central fiber or fibers. |
| IDF | intermediate distribution frame | A junction point between the MDF and concentrations of fewer connections— for example, those that terminate in a data closet. |
| d(⌒ー⌒) | inventory management | The process of monitoring and maintaining all the assets that make up a network. |
| KVM | keyboard, video, and mouse switch | A device that connects the equipment in a rack to a single console to provide a central control portal for all devices on the rack. |
| d(⌒ー⌒) | licensing restrictions | The portion of a software license that limits what a product can be used for. |
| MDF | main distribution frame | the centralized point of interconnection between an organization’s LAN or WAN and a service provider’s facility. aka: main distribution facility, main cross connection |
| MLA | master license agreement | Contract that grants a license from a creator, developer, or producer, to a third party for the purposes of marketing, sublicensing, or distributing the product to consumers as a stand-alone product or as part of another product. |
| MOU | memorandum of understanding | Document presenting intentions of 2 or more parties to enter a binding agreement/contract. Usually not legally binding & doesn't grant extensive rights to either party, provides no legal recourse & provides no thorough coverage of the agreement to come. |
| MSA | master service agreement | A contract that defines terms of future contracts. |
| d(⌒ー⌒) | network diagram | A graphical representation of a network’s devices and connections. |
| d(⌒ー⌒) | Nmap | A scanning tool designed to assess large networks quickly and provide comprehensive, customized information about a network and its hosts. |
| d(⌒ー⌒) | patch | A correction, improvement, or enhancement to part of a software application, often distributed at no charge by software vendors to fix a bug in their code or to add slightly more functionality. |
| d(⌒ー⌒) | patch management | The process of monitoring the release of new patches, testing them for use on networked devices, and installing them. |
| d(⌒ー⌒) | patch panel | A wall- or rack-mounted panel where cables converge in one location. |
| d(⌒ー⌒) | plenum | The area above the ceiling tile or below the subfloor in a building. |
| d(⌒ー⌒) | punchdown tool | A pointed tool used to insert twisted-pair wire into receptors in a punchdown block to complete a circuit. |
| PVC | polyvinyl chloride | A flame-resistant material used to manufacture cable jackets because it produces less smoke than regular cable coating materials. |
| d(⌒ー⌒) | rack diagram | A drawing that shows the devices stacked in a rack system and is typically drawn to scale. |
| RFP | request for proposal | document requesting that vendors submit a proposal for a product or service that a company wants to purchase. |

| SOW | statement of work | A document that details the work that must be completed for a particular project, including specifics such as tasks, deliverables, standards, payment schedule, and work timeline. An SOW is legally binding, meaning it can be enforced in a court of law. |
| STP | shielded twisted pair | type of copper based cable containing twisted-pair wires that are not only individually insulated, but are also surrounded by a shielding made of a metallic substance such as foil. |
| d(⌒ー⌒) | structured cabling | A method for uniform, enterprise-wide, multivendor cabling systems specified by the TIA/EIA 568 Commercial Building Wiring Standard. Structured cabling is based on a hierarchical design using a high-speed backbone. |
| d(⌒ー⌒) | system life cycle | The process of designing, implementing, and maintaining an entire network. |
| TIA | Telecommunications Industry Association | A subgroup of the former EIA that focuses on standards for information technology, wireless, satellite, fiber optics, and telephone equipment. EIA was dissolved in 2011 and its responsibilities transferred to ECA (Electronic Components, Assemblies, Equipm |
| d(⌒ー⌒) | upgrade | A significant change to an application’s existing code, typically designed to improve functionality or add new features while also correcting bugs and vulnerabilities. |
| UTP | unshielded twisted pair | A type of copper based cable that consists of one or more insulated twisted-pair wires encased in a plastic sheath, which does not contain additional shielding for the twisted pairs. |
| VoIP | Voice over IP | The provision of telephone service over a packet-switched network running the TCP/IP protocol suite. |
