| What is an input device? | A piece of hardware equipment that provides data and control signals. |
| What is an output device? | An output device is any device used to send data from a computer to another device or user. Most computer data output that is meant for humans is in the form of audio or video. Thus, most output devices used by humans are in these categories. Examples include monitors, projectors, speakers, headphones and printers. |
| What is a storage device? | A piece of computer equipment on which information can be stored |
| Give an example of input,process and output? | A camera , a central processing unit and a printer! |
| What is the purpose of a power supply? | A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer |
| What is the purpose of the computer case? | A computer case, also known as a computer chassis, tower, system unit, cabinet, base unit, or simply case, is the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse) |
| What is the purpose of the motherboard? | The Motherboard itself is a printed circuit board that allows the CPU, RAM, and all other computer hardware components to communicate with each other. There are huge variations in Motherboards from design, cases, power supply, size (Form Factor) and compatibility |
| What is the purpose of the Processor? | The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program |
| What is the purpose of the RAM? | Other than the specific applications that hog your RAM, if you think bumping your RAM from 3GB to 8GB is going to increase the speed of a regular application-like a video game—you should think again. The only thing that additional RAM does is allow your computer to do more things at once, not actually make it faster |
| What is the purpose of ROM? | Stores a program used to boot up the computer. This is called the bootstrap loader |
| What is the purpose of the Hard Drive? | Storage is the hard drive's responsibility. Everything you keep on your computer is on a hard drive. Not just documents, pictures, music and videos. Your programs, your preferences, even your operating system—they're all stored on your computer's hard drive. |
