Term 451
Licensing in IT refers to the legal agreements and permissions that govern how software, hardware, or digital content can be used, distributed, and managed.
Term 452
A lifecycle rule is a set of automated policies that move or delete data based on its age or other conditions, helping manage storage costs and compliance.
Term 453
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current passes through it, commonly used as an indicator or illumination source in electronic devices.
Term 454
Link aggregation combines multiple physical network connections into a single logical link to increase bandwidth and provide redundancy.
Term 455
Link Aggregation Control Protocol (LACP) is a standard protocol that automatically bundles multiple physical network links into a single logical link to increase bandwidth and provide redundancy.
Term 456
Link Layer Discovery Protocol (LLDP) is a vendor-neutral protocol used by network devices to advertise their identity, capabilities, and neighbors over a local area network.
Term 457
A link-local address is a network address that is automatically assigned to a device for communication only within a single network segment, without needing a router or external server.
Term 458
Liquid cooling is a method of removing heat from computer components by circulating a liquid coolant through a closed loop system instead of using air-based fans alone.
Term 459
A flat-panel display technology that uses liquid crystals manipulated by electric current to produce images, commonly used in monitors and laptop screens.
Term 460
A transitional state in the Spanning Tree Protocol where a port listens for Bridge Protocol Data Units (BPDUs) to learn the network topology but does not forward or learn MAC addresses.
Term 461
LLDP (Link Layer Discovery Protocol) is a vendor-neutral protocol used by network devices to advertise their identity, capabilities, and neighbors on a local Ethernet network.
Term 462
A load balancer is a device or software that distributes incoming network traffic across multiple servers so no single server gets overwhelmed.
Term 463
A Local Area Network (LAN) connects computers and devices within a small physical area, such as a home, office, or school, allowing them to share resources like files, printers, and internet access.
Term 464
A local connector is a cable or port used to link a device like a computer to a nearby peripheral or network within the same immediate area.
Term 465
A local route is a routing table entry for a directly connected network interface IP address, created automatically when an IP address is assigned to that interface.
Term 466
A Local Zone is an extension of a cloud provider's region that places compute, storage, and networking resources closer to a specific geographic area to reduce latency for end users.
Term 467
Long-Term Evolution (LTE) is a high-speed wireless communication standard for mobile phones and data terminals, often called 4G LTE.
Term 468
Longest prefix match is the algorithm routers use to select the most specific route from a routing table when forwarding a packet to its destination.
Term 469
Loop Guard is a Spanning Tree Protocol (STP) enhancement that prevents network loops by placing a blocked port into a loop-inconsistent state if it stops receiving Bridge Protocol Data Units (BPDUs), rather than transitioning it to a forwarding state.
Term 470
A loopback address is a special IP address that a device uses to send a message to itself, primarily for testing network software without requiring physical network hardware.
Term 471
A loopback plug is a small device used to test network ports by sending a signal out and immediately receiving it back, verifying that the port is working without needing another device.
Term 472
Low-level formatting is the process of physically structuring a hard drive by creating tracks and sectors on the magnetic platters so the drive can store data.
Term 473
A Link State Advertisement (LSA) is a data packet used by the OSPF routing protocol to share information about network links and topology with neighboring routers.
Term 474
A Link State Advertisement is a data packet used by OSPF routers to share information about their directly connected links and the state of those links with all other routers in the OSPF network.
Term 475
The Link State Database is a table maintained by OSPF routers that stores the complete network topology, including all links and routers, to calculate the best paths.
Term 476
LTE (Long-Term Evolution) is a 4G wireless broadband standard that provides high-speed data for mobile devices and networks.
Term 477
M.2 is a small, internal connector used in computers to attach compact expansion cards like solid-state drives and Wi-Fi modules directly to the motherboard.
Term 478
A MAC address is a unique hardware identifier assigned to a network interface card that allows devices to communicate on a local network.
Term 479
A MAC address table is a data structure stored in a network switch that maps each of its ports to the MAC addresses of connected devices, enabling the switch to forward frames only to the correct destination.
Term 480
MAC filtering is a security practice that allows or denies network access to devices based on their unique Media Access Control (MAC) address.
