IT Infrastructure: Structured Cabling, Documentation, and Asset Management

A set of vocabulary flashcards based on Module 02 of IT Infrastructure, covering structured cabling standards, physical network topologies, documentation standards, reliability metrics, and life cycle management.

ANSI/TIA-568

A family of enterprise-wide structured cabling standards describing uniform best practices for installing networking media to maximize performance and minimize upkeep.

Entrance Facility (EF)

The location where an incoming network, such as the Internet, connects with an organization's network, or the cabling entrance point between buildings on a campus.

Demarcation Point (Demarc)

The physical device or location that marks where a telecommunications service provider's network ends and the customer organization's network begins.

Main Distribution Frame (MDF)

The central connection point for an organization's LAN or WAN, also referred to as the main cross-connect (MC).

Patch Panel

A panel of network connections mounted to a wall or rack that provides a central termination point where multiple patch cables converge.

Intermediate Distribution Frame (IDF)

A frame or room housing networking equipment that provides an intermediate connection between the MDF and end-user equipment on each floor or building.

Patch Cable

A short, flexible cable (typically $3$ to $25$\,\text{feet} long) usually made of stranded copper with connectors on both ends, designed for frequent movement between hardware devices and outlets or patch panels.

Horizontal Cabling

Permanently installed cable, usually solid-core copper, running from the telecommunications room to the work-area outlet, with a maximum allowable total length of $100$\,\text{m}.

Backbone Cabling

Interconnecting cables or wireless links, frequently composed of fiber-optic cable, that connect the entrance facility to the MDF and the MDF to IDFs.

Hot Aisle/Cold Aisle Layout

A server rack arrangement in data centers that pulls cool air from floor or wall vents into server intakes (cold aisles) and vents hot air away through hot aisles.

Nmap

A widely used command-line utility used for network mapping, host discovery, and open port detection.

Zenmap

The official graphical user interface (GUI) application for the Nmap network scanning utility.

Wiring Schematic

A detailed graphical diagram that illustrates every wire and interconnection within a network's physical wired infrastructure.

Rack Diagram

A visual drawing showing the relative layout and vertical stacking order of hardware devices installed inside an equipment rack.

System Life Cycle (SLC)

The full end-to-end process of designing, implementing, maintaining, and eventually decommissioning an entire network or system.

Inventory Management

The systematic tracking, monitoring, and maintenance of all physical and software assets within a network.

Request for Proposal (RFP)

A formal document requesting vendors to submit binding offers for products or services required by an organization.

Memorandum of Understanding (MOU)

A document outlining a mutual intent between two or more parties to work together or enter into a formal contract.

Statement of Work (SOW)

A formal document detailing the specific tasks, deliverables, and requirements to be completed for a project.

Service-Level Agreement (SLA)

A legally binding agreement or contract clause specifying service performance standards and remedies provided by a vendor to a customer.

Master Service Agreement (MSA)

A contract that governs broad foundational terms, such as payment conditions and dispute resolution, for future agreements between parties.

Master License Agreement (MLA)

A contractual agreement granting rights from a creator or developer to a third party to market, sublicense, or distribute a product.

Mean Time Between Failures (MTBF)

A metric representing the expected operational duration between consecutive hardware or system failures.

Mean Time to Repair (MTTR)

The calculated average duration required to repair or restore a failed network component or service back to functional operation.

Single Point of Failure (SPoF)

An unredundant system component whose failure causes the entire system or network operation to fail.

Hot-Swappable Component

A modular hardware component that can be safely removed or replaced without shutting down power to the host system.

Hot Spare

A pre-installed backup component that can immediately take over operation automatically if the primary component experiences a failure.

Cold Spare

An uninstalled backup component kept in storage that requires manual installation following a hardware failure, resulting in system downtime.

Configuration Management (CM)

The administrative discipline of recording, controlling, and updating configurations to maintain operational integrity and compliance.

End-of-Support (EOS)

The designated date after which a vendor ceases providing security updates, patches, or technical support for a product.

End-of-Life (EOL)

The point in a product's life cycle when a vendor discontinues sales and eventually phases out support services.

Decommissioning

The structured procedure for safely removing an outdated asset or system from active network production.

Wireshark

An open-source network packet analyzer used to capture and inspect real-time network traffic at a granular level.
