      Desktops are very portable

    • D.

      Desktops tend to have a faster processor for a given price as compared with laptops

    Correct Answer
    D. Desktops tend to have a faster processor for a given price as compared with laptops
    Explanation
    Desktops tend to have a faster processor for a given price as compared with laptops. This is because desktop computers have more space available for larger and more powerful processors, whereas laptops have limited space and need to prioritize portability over performance. As a result, desktop computers can offer faster processing speeds at a more affordable price point compared to laptops.

    Correct Answer
    D. Heat dissipation is more difficult due to the structure of the laptop computers.
    Explanation
    Laptop computers have a more compact and enclosed structure compared to desktop computers, which makes heat dissipation more challenging. The compact design limits the space for proper ventilation, leading to a higher risk of overheating. This can result in decreased performance, potential damage to internal components, and a shorter lifespan for the laptop. Therefore, the difficulty in heat dissipation is a significant disadvantage of laptops.
