🇵🇰 The motherboard is a circuit board that is located inside the system unit of a computer. It houses important electronic components such as the computer memory, power supply, processor, and other vital parts. The motherboard acts as a central hub, connecting all the different components of the computer and allowing them to communicate with each other.

🇵🇰 A scanner is a device that converts text or graphics from a printed page into code that a computer can process. It does this by using optical character recognition (OCR) technology to scan the printed page and convert it into digital information that can be understood by the computer. Scanners are commonly used for tasks such as scanning documents, photos, or artwork and converting them into digital files that can be edited, stored, or shared electronically. Unlike printers, which produce hard copies of digital files, scanners take physical copies and convert them into digital format. Therefore, the correct answer is scanner.
