Answer : 2. "color monitor"
Explanation :

color monitor is a type of display that can adjust and display output by manipulating the Red, Green, and Blue (RGB) radiation. In a color monitor, pixels are made up of red, green, and blue sub-pixels, and by varying the intensity of these colors, a wide range of colors can be displayed on the screen. Adjusting the intensity of RGB radiation allows the monitor to display different colors and shades, providing a full spectrum of colors to the viewer. This technology is commonly used in computer monitors, television screens, and other displays to produce vibrant and accurate color representations.

Answer : 4. "none of the above"
Explanation :

The key difference lies in when the loop condition is checked. In the while loop, the condition is checked before the first iteration, potentially resulting in zero iterations. In the do-while loop, the condition is checked after the first iteration, ensuring that the loop body is executed at least once.

Answer : 2. "RAM "
Explanation :

RAM (Random Access Memory) is an example of volatile memory. Volatile memory is a type of computer memory that requires power to maintain the stored information. When the computer is powered off or restarted, the data stored in RAM is erased. This is in contrast to non-volatile memory like hard drives or SSDs, where data is retained even when the power is turned off. Volatile memory, such as RAM, provides fast access to data for the computer's processor but does not retain data when the system is powered down.
