Semiconductor engineering lesson on PN-junction diode current–voltage physics: minority-carrier injection, the Shockley equation, reverse saturation current, ideality factor, temperature, diffusion capacitance, dynamic resistance, and small-signal modeling.
-
Bandwidth measures network capacity, throughput measures the data rate actually achieved, and latency measures delay. Here is how the three metrics differ and why a fast link can still feel slow.

Learn Windows net start: list running services, start services safely, identify service names, verify state with sc query, troubleshoot failures, and compare CMD with PowerShell.
-
Equal-Cost Multipath, or ECMP, is a routing technique that allows a router or Layer 3 switch to use multiple paths toward the same destination when those paths have equivalent routing costs. Instead of forcing all traffic through a single best route, ECMP can create a set of valid next hops and distribute network flows across…
