Computer building is the process of assembling a personal computer from individual components. This typically includes a motherboard, CPU (central processing unit), RAM (random access memory), storage (like SSDs or HDDs), a power supply, and a case to house everything. Each part plays a crucial role in the computer's performance and functionality. To build a computer, one must carefully select compatible components and follow a series of steps to connect them. This involves installing the CPU onto the motherboard, adding RAM, connecting storage devices, and ensuring proper power supply connections. Once assembled, the computer can be powered on and configured for use.
