Understanding Computer Hardware

This video tutorial provides an overview of computer hardware, explaining the physical components like memory, motherboard, and CPU. It delves into how hardware uses electrical signals to process binary instructions, the role of bits and bytes, and how logic gates perform computations. The video also covers different types of memory, including RAM and ROM, and illustrates how these components work together through a practical example.
