This article explains the different Cisco device configuration modes—user, privileged, global, and interface—provides command examples for setting hostnames, viewing version and MAC tables, and configuring duplex and speed settings on switch ports, illustrated with screenshots.
Explore the inner workings of Node.js streams—including readable, writable, duplex, transform, and pipe—through detailed explanations, code demos, and visual diagrams, revealing how backpressure, flow modes, and internal mechanisms shape data handling in backend development.
The article explains Node.js’s Stream API by detailing the four core stream classes—Readable, Writable, Duplex, and Transform—showing how to implement them, manage back‑pressure, enable objectMode, and apply these concepts in real‑world tools like Gulp, Browserify, and a Git‑changelog generator.
Node.js streams provide four core types—Readable, Writable, Duplex, and Transform—plus an objectMode for arbitrary data, and by using .pipe() they enable flow‑controlled processing with back‑pressure, as illustrated through detailed explanations, Gulp and Browserify case studies, and a hands‑on changelog generator example.
