A motherboard (also called mainboard, main circuit board, system board, baseboard, planar board, logic board, is the main printed circuit board (PCB) in general purpose computers and other expandable systems, The first motherboards held very few actual components. The first IBM PC motherboard had only a processor and card slots. Users plugged components like floppy drive controllers and memory into the slots 01 02 03 PCI Slots, Microprocessor, IDE cable Card Reader, RAM, Graphics and Audio Card Power Port, Battery, PCI & RAM Slots What is a power supply? Abbreviated as PS or P/S, a power supply or PSU (power supply unit) is a hardware component of a computer that supplies all other components with power. The power supply converts a 110-115 or 220-230 volt AC (alternating current) into a steady lowvoltage DC (direct current) usable by the computer and rated by the number of watts it generates. The image shows an Antec True 330, a 330 Watt power supply. What are the three types of power supply? There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. The fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself. Unregulated Linear regulated Switching Unregulated Unregulated/ is the simplest of power supplies to construct, a diodes ability to switch current in one direction only makes it deal for converting a two directional alternating current into a constant direct current or DC supply. Liner regulated Liner regulated/ regulates the output voltage by dropping excess voltage in a series dissipative component, They use a moderately complex regulator circuit to achieve very low load and line regulation. Switching Switching/ 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 DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics Is power supply a battery? A power supply is designed to supply a constant voltage to a load. As the load requirements change, it continues to supply a fixed DC level. A true battery charger generally supplies a regulated current, first to charge the battery, and then switches to a regulated voltage mode. What are the types of motherboard?
