Key Points Alarm Management System is a software system for handling alarms and operator notification Used in operational and control contexts Prevents operators from being overwhelmed by too many or poorly designed alarms Used in industrial automation, control rooms, utilities,…
Key Points Indicates lost network data units Affects throughput and quality Common in congested or impaired networks Used as a quality and reliability metric Definition Packet Loss is the failure of one or more packets to reach their destination across…
Key Points Adds protocol headers or trailers Used across layered network stacks Supports interoperability and transport Common in networking and tunneling Enables lower layers to carry higher-layer data without needing to understand its internal format Definition Encapsulation is the process…
Key Points Occurs on the receive side of a downlink Can originate from nearby channels or external emitters Reduces signal quality, throughput, and service availability Managed through spectrum coordination, antenna discrimination, filtering, and receiver sensitivity optimization Primary impacts include reduced…
Key Points Describes service performance characteristics in measurable terms Can be implemented through policy or network controls such as queueing, classification, shaping, or admission controls Often measured alongside latency and reliability Used in communication and service design across enterprise networking,…
Key Points Captures events for analysis Supports troubleshooting and audit Used in software, infrastructure, and operations May be structured or unstructured Provides traceability and an audit trail Used across application development, cloud operations, cybersecurity, networking, and industrial systems Definition Logging…
Key Points Keeps some state or services preloaded Fails over faster than cold standby Uses more resources than a fully inactive backup Balances readiness with resource cost Reduces recovery time compared with starting from scratch Definition Warm Standby System is…
Key Points Centralized network monitoring and response Tracks alarms, performance, and incidents Coordinates troubleshooting, escalation, and service continuity Primary use in telecom and service operations Definition Network Operations Center is the operational facility that monitors, manages, and responds to events…
Key Points Port Exhaustion is the depletion of available ports for new transport sessions Operates across network and system environments Prevents new session creation even when other network capacity remains Occurs in NAT gateways, proxies, and high-connection networks Definition Port…
Key Points Receives and retransmits signals Often changes frequency or channel Used in satellite and radio relay systems Fundamental to bent-pipe and regenerative payload architectures Constraints include gain, linearity, noise, frequency plan, and isolation Failure modes include overload, intermodulation, frequency…
