MOSFET
Zero Voltage switching is a standard used to describe electrical appliances which turn on or off only when the output voltage is Zero.
its a opto coupler. And generaly used for high speed switching.
The two main functions of a transistor are: (a) signal amplification, and (b) solid-state switching.
Copper is a reddish brown element used for electrical wiring as it is a good conductor of electricity.
Mercury Bulb, heat-anticipator and a cold-anticipator.
A switched-mode power supply (switching-mode power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a source, like mains power, to a load, such as a personal computer, while converting voltage and current characteristics.An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage. thus it is used in all electronic devices that are directly connected to a DC power source
SMPS stands for Switched-Mode Power Supply. It is an electronic power supply that efficiently converts electrical power using switching devices such as transistors. SMPS are commonly used in electronic devices to provide stable and regulated power to sensitive components.
Basic difference between these are :- AT means "Advance Technology" while ATX is used for "Advance Technology Extended" SMPS. With respect to AT SMPS, ATX has an extra Plug of +12v Supply for Motherboard. It has four wires connected in square size plug. Two of them are Yellow and other two are black.
A switch, circuit breaker, fuse, or switching transistor can do that.
Switching is typically used in the context of switching phone lines or switching digital networks. It could also be used in the context of switching companies that provide services such as water or electric.
Circuit switching and Packet switching are used in Telephony. Circuit switching is used in voice communication and packet switching is used in transmission of data packets to provide internet connection.
SMPS [Switch Mode Power Supply ] also known as PSU [Power Supply Unit] is used in desktops to convert AC TO DC and to divide voltage to appropriate units to different components.... Since Laptops has a adapter [which does the job] which comes with the charger a seperate smps is not needed........ or Its included in the package..to be more clear yes laptops need smps
Packet Switching =)
It is an switching element that provides and manges radio resources through traiffice channels on the Base Transceiver Station (BTS). It also is used to track location of UEs and provide handovers during roaming.
packet switching is use today
An SMPS is a switched-mode power supply. It is used to convert an unregulated power input into a regulated power output, often altering the voltage. In a modern computer, several components may be powered from the same power supply but will often require different regulated voltages. The SMPS fulfils this role.
