Beginning in school, and continuing at successively higher levels across their college studies, students should prepare for twenty-first-century challenges by gaining: Intellectual and Practical Skills, including critical and creative thinking. They will have to learn what the parts of the computer how and how to put them together to build a functioning computer. Students will also have chances to troubleshoot computers that are experiencing problems.
Computer hardware includes the physical parts of a computer , such as the case ,  central processing unit CPU , monitor , mouse , keyboard , computer data storage , graphics card , sound card , speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard " or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware.

Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing tower. A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer. In contrast to software, hardware is a physical entity.
