    Which of the following is an output device?

    • Keyboard

    • Mouse

    • Printer

    • Scanner

    Correct Answer
    A. Printer
    Explanation
    An output device is a device that receives information from a computer and displays or prints it. A printer is an output device as it takes digital information from a computer and produces a physical copy of it on paper. The keyboard and mouse are input devices as they allow the user to input information into the computer. The scanner is also an input device as it allows the user to input physical documents or images into the computer.

    If your computer will not come on what should be checked first?

    • RAM

    • Power

    • ROM

    • Network Cable

    Correct Answer
    A. Power
    Explanation
    If the computer will not come on, the first thing that should be checked is the power source. This is because if there is no power supply, the computer will not be able to turn on. It is important to ensure that the power cable is properly connected to both the computer and the power outlet, and that there is electricity flowing to the outlet. By checking the power source first, any potential power-related issues can be identified and resolved, allowing the computer to turn on successfully.

    What device is an example of an input device?

    • Microphone

    • Printer

    • Monitor

    • CPU

    Correct Answer
    A. Microphone
    Explanation
    A microphone is an example of an input device because it allows users to input audio into a computer or recording device. It converts sound waves into electrical signals that can be processed and stored. This makes it possible to record voice, music, or any other sound and use it as input for various applications such as voice recognition, audio recording, or video conferencing. Unlike printers, monitors, and CPUs, which are output or processing devices, a microphone specifically functions to input audio data into a system.

    When you open a program or play a game all information is stored in this location until it is saved to a more permanent location. Hint:  Your computer may run slow if you don't have enough of this item installed.

    • RAM

    • ROM

    • CPU

    • Hard Drive

    Correct Answer
    A. RAM

    Input, Process, Output and Storage combine to make what cycle?

    • Computer Cycle

    • Input/Output Cycle

    • Data Storage Cycle

    • Information Processing Cycle

    Correct Answer
    A. Information Processing Cycle
    Explanation
    The combination of Input, Process, Output, and Storage in a computer system is known as the Information Processing Cycle. This cycle represents the flow of data and information within a computer system. Input refers to the data that is entered into the system, Process involves the manipulation and transformation of this data, Output is the result or information that is produced by the system, and Storage is the retention of data for future use. The Information Processing Cycle encompasses all these stages, illustrating how data is processed and transformed into meaningful information.

    What device stores your pictures, music, applications and videos on a personal computer system?

    • RAM

    • ROM

    • CPU

    • Hard Drive

    Correct Answer
    A. Hard Drive
    Explanation
    A hard drive is a device that stores pictures, music, applications, and videos on a personal computer system. It is a non-volatile storage device that retains data even when the computer is turned off. Unlike RAM (Random Access Memory) and ROM (Read-Only Memory), which are temporary and permanent storage respectively, the hard drive provides long-term storage capacity for various types of files. The CPU (Central Processing Unit) is responsible for executing instructions and performing calculations, but it does not directly store files.
