A course on computer parts and functions, also known as a Computer Hardware Essentials or Computer Concepts course, teaches students about the physical components of a computer system (hardware) and their roles in input, processing, storage, and output.
This course introduces learners to the essential parts of a computer, their functions, and how they work together to make a computer system operate effectively. Students will explore internal components such as the motherboard, CPU, RAM, and storage devices, as well as external devices like monitors, printers, keyboards, and network equipment. The course also covers ports, connectors, and safe handling of computer hardware.
Learners will gain both theoretical knowledge and practical understanding of identifying, assembling, and maintaining computer components. By the end of this course, students will be able to describe computer parts, explain their roles, and demonstrate basic troubleshooting and care practices.
