NET140 ch2 set1

A signaling protocol used to make an initial connection between hosts but does not participate in data transfer during the session. It is commonly used by voice gateways to initiate and maintain connections.

• SIP (session initiation protocol)

• HTTP (Hypertext Transfer Protocol)

• FTP (File Transfer Protocol)

• SMTP (Simple Mail Transfer Protocol)

Also known as the main cross connect, it is the centralized point of interconnection between an organization’s LAN or WAN and a service provider’s network.

• MDF (main distribution frame)

• IDF (intermediate distribution frame)

• Patch Panel

• Router

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.

• KVM (keyboard, video, and mouse switches)

• USB Hub

• Network Switch

• Power Distribution Unit

The area above the ceiling tile or below the subfloor in a building.

• Plenum

• Crawl Space

• Attic

• Basement

A type of interference caused by signals traveling on nearby wire pairs infringing on another pair’s signal.

• Crosstalk

• Interference

• Signal Loss

• Noise

The organization of cables in a way that supports highest potential performance of the cables and the hardware they connect, while minimizing the risk of damage or injury.

• Cable management

• Cable organization

• Cable arrangement

• Cable optimization

A method for uniform, enterprisewide, multivendor cabling systems specified by the ANSI/TIA-568 family for standard. It is based on a hierarchical design using a high-speed backbone.

• Structured cabling

• Fiber optic cabling

• Coaxial cabling

• Twisted pair cabling

A junction point between the MDF and concentrations of fewer connections, for example, those that terminate in a data closet.

• IDF (intermediate distribution frame)

• MDF (main distribution frame)

• Patch Panel

• Network Switch

A type of copper-based cable containing twisted-pair wires with metallic shielding such as foil around each wire pair and/or shielding surrounding all four wire pairs.

• STP (shielded twisted pair)

• UTP (unshielded twisted pair)

• FTP (foiled twisted pair)

• S/FTP (shielded foiled twisted pair)

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 through the central fiber or fibers.

• Fiber-optic cable

• Coaxial cable

• Twisted pair cable

• Ethernet cable
