Course Introduction
Introduction to Computer Hardware provides students with a foundational understanding of the physical components that make up a computer system. The course covers the essential elements such as the central processing unit (CPU), memory (RAM and storage), input/output devices, motherboards, power supplies, and peripheral devices. Students will learn how these components interact, how to assemble and disassemble basic hardware systems, and the principles behind hardware troubleshooting and maintenance. Emphasis is placed on both theoretical knowledge and hands-on practice, preparing students for more advanced studies in computer engineering and information technology.

For example, when you tap your smart phone with that of your friend, the two phones can use NFC to exchange contact information. NFC can also be used to read an NFC tag, which is a small microchip that can be embedded in just about anything, including a key chain tag, printed flyer, or billboard. The NFC tag dispenses information to any NFC-enabled smart phone or other device that comes within 4 inches of the tag.
