Random Access Memory (RAM) is a type of computer storage that temporarily holds data and applications while your computer is running. The RAM modules are connected to the motherboard via slots, and they receive power from the PSU.
The Storage Drive: Where Your Data Lives
The storage drive is where your operating system, programs, and data are stored. This can be a hard drive, solid-state drive, or hybrid drive, and it’s connected to the motherboard via a SATA or PCIe interface.
The Peripherals: The Final Pieces of the Puzzle
While the power cord, PSU, motherboard, CPU, RAM, and storage drive are the essential components that need to be plugged in for your PC to boot, there are several peripherals that need to be connected for your computer to function properly.
The Keyboard and Mouse: The Input Devices
The keyboard and mouse are the primary input devices that allow you to interact with your computer. They’re connected to the motherboard via USB ports or PS/2 connectors.
The Monitor: The Output Device
The monitor is the output device that displays the graphics and text from your computer. It’s connected to the motherboard via a VGA, DVI, HDMI, or DisplayPort interface.
The Power Button: The Trigger That Starts It All
The power button is the trigger that starts the boot process. When you press the power button, it sends a signal to the motherboard, which activates the PSU and starts the flow of power to the various components.
Conclusion
In conclusion, for your PC to boot, several crucial connections need to be made. The power cord provides the electrical current, the PSU converts it into DC power, and the motherboard connects all the hardware components together. The CPU, RAM, and storage drive are connected to the motherboard, and the peripherals such as the keyboard, mouse, and monitor are connected to the motherboard or other components.
