Key Points Central hub connects many endpoints Reduces direct interconnection complexity Common in networking and logistics Creates a central dependency Hub capacity and latency are key constraints Single point of failure risk if hub redundancy is not designed Definition Hub…
Key Points Carries remote control commands from operator to aircraft Paired with telemetry return for feedback and monitoring Must maintain reliability and low latency for safe operation Constraints include range, latency, interference, line of sight, and power requirements Critical for…
Key Points Targets remote or sparsely populated areas Often uses mixed access technologies including fiber, fixed wireless, or satellite Important for digital inclusion and service reach Used in regional access planning, fixed wireless deployment, fiber expansion, and satellite-enabled service models…
Key Points Collision Domain defines the scope where transmissions can collide on a shared medium Exists to describe contention on Layer 1 or Layer 2 links Primary relevance in Ethernet history, shared media design, and network segmentation Matters most when…
Key Points Protects payload content from unauthorized reading Used in secure communications and transport Often paired with key management and access control Combines data transport with information security Used in satcom, secure networking, and protected data transport Encryption helps preserve…
Key Points Tracks flow across system boundaries Used in observability and debugging Supports latency and dependency analysis Common in distributed systems Reveals dependencies between services and components Identifies where time is spent in transactions Definition Tracing is the recording or…
Key Points State Estimation is defined for network or system use. Inference of hidden or internal system state from available data. Used in operational and control contexts. Works by combining observations with a model to estimate values that are not…
Key Points Demultiplexing is the separation of combined data or signal streams into their component parts Used across network and system contexts for restoring individual flows Works by using identifiers, timing, encoding, or channel structure to split combined streams Operates…
Key Points Supports precise pointing control Transfers angular momentum without propellant Common in spacecraft attitude control systems Works by exchanging angular momentum between the wheel and spacecraft body Enables stable pointing for antennas, sensors, and payloads Definition Reaction Wheel is…
