    This stands for Random Access Memory.  Computers use it to store instructions and data while it is running.  

    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that is used to store instructions and data while the computer is running. RAM is volatile, meaning that its contents are lost when the computer is turned off or restarted. It allows the computer to quickly access and retrieve data, which helps in improving the overall performance and speed of the system. R.A.M. is just an abbreviation for RAM, both representing the same concept.

  • 4. 

    A small piece of silicon on which circuits are etched

    • A.

      Microchip

    • B.

      CPU

    • C.

      Vacuum tubes

    • D.

      Hard disk

    Correct Answer
    A. Microchip
    Explanation
    A microchip is a small piece of silicon on which circuits are etched. It is commonly used in electronic devices to store and process information. Unlike vacuum tubes or hard disks, which are also used in electronics, a microchip is specifically designed to contain integrated circuits that enable the device to function efficiently. A CPU, or central processing unit, is a type of microchip that acts as the brain of a computer or electronic device, handling all the calculations and instructions. Therefore, microchip is the correct answer as it accurately describes the given definition.

  • 5. 

    True or false - digital information is recorded in a continuous stream of data, like sound waves on a record player or a graphic representation of earthquake energy (a seismometer).  An example of digital information is a cassette tape.  This is different from analog information, which is recorded as a combination of 1s and 0s.  

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is false. Digital information is not recorded in a continuous stream of data like sound waves or a seismometer. Digital information is recorded as a combination of 1s and 0s, representing binary code. A cassette tape, on the other hand, is an example of analog information as it records sound waves in a continuous manner.

    The smallest unit on a display screen grid that can be stored, displayed, or changed. 

    • A.

      Pixie

    • B.

      Retina

    • C.

      Pixel

    • D.

      Microchip

    Correct Answer
    C. Pixel
    Explanation
    A pixel is the smallest unit on a display screen grid that can be stored, displayed, or changed. It refers to a single point in an image or a display, and it is the building block of digital images. A pixel represents a specific color and intensity, and when combined with other pixels, it forms the complete image that we see on a screen.

    These are older, larger devices that controlled how electric current flowed.  Computers used these to process digital information before microchips and transistors were invented.  

    Correct Answer
    vacuum tubes
    vacum tubes
    vacum tube
    vacum tubes
    vacuum tube
    vacume tubes
    vacum tubes
    Explanation
    Vacuum tubes were older, larger devices that controlled how electric current flowed. Computers used these vacuum tubes to process digital information before microchips and transistors were invented.

    Rate this question:

  • 8. 

    The smallest piece of information used by the computer.  This very short word is an amalgamation (a combination) of the words "binary" and "digit".  

    Correct Answer
    bit
    bits
    a bit
    Explanation
    A bit is the smallest unit of information used by a computer. It is a combination of the words "binary" and "digit". In computing, information is stored and processed in binary form, which means it is represented using only two digits, 0 and 1. A bit can represent either a 0 or a 1, and it is the fundamental building block for all computer data. Multiple bits combined together form larger units of information, such as bytes, kilobytes, and so on. Therefore, the correct answers for this question are "bit", "bits", and "a bit".

    This early computer weighed 30 tons and was built for the US army in the 1940s

    • A.

      IBM

    • B.

      ENIAC

    • C.

      IPad mini

    • D.

      HAL

    Correct Answer
    B. ENIAC
    Explanation
    ENIAC is the correct answer because it was an early computer that was built for the US army in the 1940s and it indeed weighed 30 tons. IBM is a well-known computer company, but it does not specifically refer to the early computer described. iPad mini is a modern tablet and HAL is a fictional computer from the movie "2001: A Space Odyssey", neither of which fit the description of the early computer.

    This is a storage location inside the CPU used to keep track of bytes and bits - it stores data for the CPU.  

    • A.

      Hard disk

    • B.

      Memory register

    • C.

      Graphics card

    • D.

      Floppy drive

    Correct Answer
    B. Memory register
    Explanation
    A memory register is a storage location inside the CPU that is used to keep track of bytes and bits. It stores data for the CPU, allowing it to quickly access and manipulate information. This is different from a hard disk, which is a separate storage device used for long-term data storage, or a graphics card, which is responsible for rendering images and videos. A floppy drive is also a separate storage device, but it is outdated and not commonly used anymore.

    How do you represent the number 3 in binary? 

    • A.

      001

    • B.

      010

    • C.

      011

    • D.

      3.14159

    Correct Answer
    A. 001
    Explanation
    The number 3 in binary is represented as 001. In binary representation, each digit can be either 0 or 1. The rightmost digit represents the value of 2^0, the next digit represents the value of 2^1, and so on. In this case, the rightmost digit is 1, indicating that 2^0 is included in the binary representation of 3. The other two digits are 0, indicating that 2^1 and 2^2 are not included. Therefore, the correct binary representation for 3 is 001.

    The computer's immediate internal PRIMARY memory  - it is fast, easily accessible, and allows the computer to complete many tasks at once - but it but does not last when the power goes out and is not useful for permanent storage.  

    • A.

      Secondary memory

    • B.

      RAM

    • C.

      DVD

    • D.

      Hard disk

    Correct Answer
    B. RAM
    Explanation
    RAM (Random Access Memory) is the computer's immediate internal primary memory. It is fast and easily accessible, allowing the computer to complete many tasks simultaneously. However, RAM does not retain data when the power goes out, making it volatile. It is not suitable for permanent storage as it is designed for temporary storage of data that the computer is actively using. Secondary memory, such as a hard disk or DVD, is used for long-term storage of data.

    The main COMPUTER PROGRAM on your computer that directs all the activities and sets rules for how hardware and software work together

    • A.

      CPU

    • B.

      Motherboard

    • C.

      Application

    • D.

      Operating system

    Correct Answer
    D. Operating system
    Explanation
    The operating system is the main computer program that directs all the activities and sets rules for how hardware and software work together. It acts as an intermediary between the user and the computer hardware, managing tasks such as memory allocation, file management, and device input/output. The operating system provides a platform for other software applications to run on and ensures that they can communicate with the hardware effectively. Without an operating system, a computer would not be able to perform any tasks or run any programs.

      Computer mouse

    • D.

      Microphone

    Correct Answer
    B. Computer monitor
    Explanation
    A computer monitor is used to display or output information from a computer. It is a visual output device that allows users to see the results of their actions on the computer. It can display text, images, videos, and other types of multimedia content. The keyboard, computer mouse, and microphone are input devices that are used to input information into the computer, not to output it.
