Term 572
A public cloud is a computing model where third-party providers deliver IT resources like servers, storage, and applications over the internet to multiple customers on a pay-as-you-go basis.
Term 573
A globally unique IP address assigned to a device that allows it to communicate directly over the internet.
Term 574
A public subnet is a segment of a cloud Virtual Private Cloud (VPC) or traditional network that has a direct route to the internet via an Internet Gateway, allowing resources within it to send and receive traffic from the public internet.
Term 575
A punchdown tool is a handheld device used by network technicians to push wires into insulation-displacement connectors on keystone jacks, patch panels, and punchdown blocks, securing a reliable electrical connection without stripping the insulation.
Term 576
Pvs (Physical Volume) is a foundational storage unit in Linux LVM (Logical Volume Manager) that represents a physical disk or partition used to build flexible, resizable storage pools.
Term 577
QoS (Quality of Service) is a network technique that manages data traffic to ensure critical applications get the bandwidth and low latency they need.
Term 578
A Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver module used in networking to connect switches, routers, and servers to fiber optic or copper cables, supporting four data channels in one module.
Term 579
Quality of Service (QoS) is a set of technologies used to manage network traffic by prioritizing certain types of data to ensure reliable performance for critical applications.
Term 580
Quarantine is a security process that isolates a potentially malicious file, email, or device from the rest of the system to prevent harm while it is analyzed or remediated.
Term 581
RA-GRS (Read-Access Geo-Redundant Storage) is an Azure storage replication option that provides read access to a secondary region copy of your data, even if the primary region becomes unavailable.
Term 582
RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disk drives into one or more logical units for improved performance, fault tolerance, or both.
Term 583
RAID 0 is a storage configuration that combines multiple hard drives into one logical unit to improve speed and capacity, but with no fault tolerance or data protection.
Term 584
RAID 1 is a data storage method that creates an exact copy of data on two or more drives so that if one fails, your information is safe.
Term 585
RAID 10 combines RAID 1 mirroring and RAID 0 striping to provide both high performance and fault tolerance by writing identical data across mirrored pairs that are then striped for speed.
Term 586
RAID 5 is a disk array configuration that uses block-level striping with distributed parity to provide fault tolerance and good read performance while using storage space efficiently.
Term 587
RAM (Random Access Memory) is your computer's short-term memory, temporarily holding data the CPU needs right now or very soon.
Term 588
Rapid provisioning is the automated and fast deployment of IT resources, such as servers, storage, and networking, often through templates and scripts, to reduce setup time from days to minutes.
Term 589
A Rapid Security Response is an emergency software patch from Apple that fixes critical security flaws in iOS, iPadOS, macOS, and other Apple operating systems without requiring a full system update.
Term 590
Rapid Spanning Tree Protocol (RSTP) is a network protocol that prevents loops in Ethernet networks by quickly recalculating the best path when a link fails.
Term 591
Remote Desktop Protocol is a Microsoft protocol that lets you connect to and control another computer over a network as if you were sitting in front of it.
Term 592
A Reachability Analyzer is a tool or feature that tests whether a network path exists between two endpoints, verifying connectivity and identifying potential routing or firewall issues.
Term 593
A read replica is a copy of a database that is used only to handle read queries, taking load off the primary database.
Term 594
Read-access geo-redundant storage (RA-GRS) is a cloud storage replication option that maintains three synchronous copies in one primary region and three asynchronous copies in a secondary region, while allowing read access to the secondary copy even during normal operations.
Term 595
Received Signal Strength Indicator (RSSI) is a measurement of how strong a wireless signal is when it reaches a receiving device, like a laptop connecting to Wi-Fi.
Term 596
A receiver is a hardware device or software component that accepts incoming signals, data, or transmissions from a sender over a communication channel.
Term 597
A hidden section on a computer's hard drive that contains the files needed to restore the operating system to its factory state.
Term 598
Recovery point objective (RPO) is the maximum acceptable amount of data loss measured in time, determining how frequently backups must be taken.
Term 599
Recovery time objective (RTO) is the maximum acceptable time that an IT system can be offline after a failure before the business is severely impacted.
Term 600
Red-Green-Blue (RGB) is a color model that combines red, green, and blue light to create a wide range of colors, primarily used in digital displays and imaging systems.
