What stores the BIOS in a PC?

A computer's basic input/output system (BIOS) is a program that's stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware.

What are the parts and function of motherboard?

The motherboard is sometimes shortened to Mobo. Numerous major components, crucial for the functioning of the computer, are attached to the motherboard. These include the processor, memory, and expansion slots. The motherboard connects directly or indirectly to every part of the PC.

Where is motherboard located?

A computer motherboard is located inside the computer case and is where most of the parts and computer peripherals connect. With tower computers, the motherboard is on the left or right side of the tower and is the biggest circuit board.

What does motherboard do in a computer?

What does a motherboard do? It's the circuit board that connects all of your hardware to your processor, distributes electricity from your power supply, and defines the types of storage devices, memory modules, and graphics cards (among other expansion cards) that can connect to your PC.

What is a keyboard controller?

Technically, a keyboard controller is a device with piano or synth-style keys, and usually a selection of knobs, buttons, and sliders. All of these transmit MIDI data to external sound modules (synthesizers), computer software synthesizers, or a hardware or software sequencer.

Is keyboard connected to CPU?

All wireless keyboards have a receiver plugged into the computer (usually by USB connection), and the keyboard connects to that receiver wirelessly. Connect this receiver either into the back or front of your computer.

Do keyboards have memory?

Keyboards typically do not have any software or memory. There are a few rare exceptions, such as the Logitech G19 gaming keyboard which has a little computer built into it to run applications, but for a typical USB (or P/S 2) keyboard, you have nothing to fear.

Does a keyboard have a microcontroller?

Modern keyboards tend to have a single microchip with a small amount of auxiliary components (typically resistors and capacitors) while older keyboards would have a number of additional support chips in addition to the microcontroller.

What is the difference between keyboard controller and keyboard buffer?

Keyboard controller places a coed in the buffer of the keyboard to indicate which key was pressed. Keyboard buffer is a temporary memory of the keyboard controller. The keyboard controller sends a signal to the system software notifying that something happened at the keyboard.

How does a keyboard communicate with the CPU?

First, a switch beneath the key closes, and current flows into a small chip in a keyboard. Each key has a scan code number, which corresponds to its position on the keyboard. The keyboard transmits this number as binary data to the computer's CPU.

Where is ROM located in motherboard?

On-board ROM chips with program data will carry the motherboard manufacturer's name instead. While not guaranteed, the ROM chips are usually placed near the motherboard's Southbridge/Chipset and the peripheral card slots.
