POWER SUPPLY UNIT-SMPS (SWITCH MODE POWER SUPPLY)

Image
A power supply unit (PSU) is the component that supplies power to the other components in a computer. More specifically, a power supply unit is typically designed to convert general-purpose alternating current (AC) electric power from the mains (100-127V in North America, parts of South America, Japan, and Taiwan; 220-240V in most of the rest of the world) to usable low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits. The most common computer power supplies are built to conform to the ATX form factor. This enables different power supplies to be interchangeable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard, and provide support for modern functions such as the standby mode available...

What Happens When You Press A Key

To illustrate how the computer works, let's take a very simple example. Let's suppose you are working in your word processor and you type the letter "M". Here's what happens, in general terms, when you press the " M " button: The keyboard sends an electrical signal, called a scan code, to the computer saying that a button was pressed. The keyboard controller interprets the scan code and determines that the letter pressed was an " M ". It stores this " M " in a special memory location until the processor is ready to deal with it. The controller sends a signal to the processor, called an interrupt. An interrupt tells the processor that some part of the computer has information for it to process and wants its attention. In this case, the keyboard controller wants the processor to look at the key you just pressed. The processor is almost always doing many things, sharing its time among many tasks. As a result, most every event must wait i...
