Packet switching is a network transmission method that sees data sent in small blocks called packets rather than as a continuous stream. Sending data in this way helps to improve the robustness and ...

If you thought that the digital TV transition, with its billion-dollar coupon program for converter boxes, was a migration nightmare, wait until it's time for the phone system to dump its legacy ...

The circuit above is in steady state with the switch open and the SCR is in the conducting state. The voltage drop across the SCR is 1 V while it is conducting. The switch is then closed at t = 0 , ...

Circuits as WAN connections battled successfully against packets for years because they guaranteed bandwidth, no matter what. If you bought a T-1 circuit, the service provider nailed up 1.5Mbps from ...

Integrated circuit technologies are enabling intelligent, chip-based, optical packet switch matrices. Rapid real-time re-configurability at the photonic layer using integrated circuit technologies is ...

Voice over IP (VoIP) is set to transform telecommunications in the next five to 10 years. And with telecom companies moving their telephone calls from circuit-switched telephone networks to ...

SMPS is the abbreviation of switching mode power supply, a kind of high-frequency power conversion device and a power supply device. Its function is to convert a level of voltage to the voltage or ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.

Sometimes the simplest questions are the best. On our last Network World/Tolly State of the LAN tour, a network manager in attendance said the following (and I paraphrase): “OK. Ethernet is great.

Many hardware people around these parts will be familiar with devices used as switches, using at least three-terminals to effect this, an input, an output and a gate. Typical devices that spring to ...
