Which item is an input device?
Answer : C
An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. Input devices enable users to input information into the computer system. Let's break down the options:
* Flash Drive (A): A flash drive (also known as a USB drive or thumb drive) is a storage device, not an input device. It allows you to store and transfer data but does not directly input data into the computer.
* CD (B): A CD (compact disc) is also a storage medium, typically used for storing audio, video, or software files. Like a flash drive, it is not an input device.
* Scanner : A scanner is a classic example of an input device. It captures physical documents, images, or text and converts them into digital data that the computer can process. Scanners are commonly used for tasks like digitizing photos, creating PDFs, or scanning documents.
* Printer (D): A printer is an output device, not an input device. It produces hard copies (printed documents) based on digital data received from the computer.
In summary, the correct answer is C. Scanner, as it directly inputs data into the computer system.

Which motherboard component is used for short-term storage of data?
Answer : B
* RAM (Random Access Memory) is the motherboard component used for short-term storage of data.
* RAM is a type of computer memory that can be read and written. It serves as temporary storage for data that the CPU (Central Processing Unit) needs to access quickly.
* When you run programs or open files, the data is loaded into RAM from storage devices (such as hard drives or SSDs). The CPU can then access this data rapidly, allowing for efficient execution of tasks.
* Unlike permanent storage (such as hard drives), RAM is volatile, meaning its contents are lost when the computer is powered off or restarted.
* RAM is crucial for overall system performance. The more RAM a computer has, the better it can handle multitasking, large applications, and data-intensive tasks.
* In summary, RAM provides fast, temporary storage for data that the CPU actively uses during program execution.
