The most important feature of a monitor is its resolution.

Input devices are responsible for converting sound into a format that can be processed by the system unit. The term "ऑडियो" translates to "audio" in English, which refers to the process of capturing and converting sound. Therefore, ऑडियो is the correct answer as it correctly represents the input device responsible for handling sound.

The correct answer is "थर्मल" (thermal). Thermal printers use heat to transfer images onto heat-sensitive paper. This process involves heating specific areas of the paper to create the desired image. Unlike inkjet or laser printers, thermal printers do not use ink or toner cartridges. Instead, they rely on heat to produce high-quality prints.

The correct answer is "थर्मल" because thermal printers use special heat-sensitive paper to produce images. This type of printer uses heat to transfer ink onto the paper, eliminating the need for ink cartridges or ribbons.

The given statement explains that the term "hardware" is used to refer to the devices that are used to convert the words, sounds, images, and actions understood by people into a format that can be processed by a system unit. In this context, "input devices" are the devices that are used to input data or instructions into a computer system. Therefore, the correct answer is "इनपुट डिवाइस" which translates to "input device" in English.

In this type of pointing device, there are invisible infrared beams that are emitted from a plastic outer layer, which is protected. This description matches the features of a touch screen, where the user can interact with the device by touching the screen. Therefore, the correct answer is touch screen.

The correct answer is "स्पष्टता" (clarity). This answer is supported by the fact that the question is asking about the quality and intensity of displayed images. "स्पष्टता" is a Hindi word that translates to "clarity" in English, which directly relates to the quality of images being displayed.

The correct answer is सीआरटी (CRT). CRT stands for Cathode Ray Tube, which is a type of display technology used in traditional television sets. This type of monitor has a similar appearance to a traditional television set and uses a cathode ray tube to display images.

The correct answer is "डीपीआई" (DPI). DPI stands for Dots Per Inch, which is a measure of the resolution of a monitor. It refers to the number of pixels that can be displayed per inch on the screen. A higher DPI value indicates a higher resolution and sharper display.

The correct answer is "टीएफटी" (TFT). A TFT monitor is a type of display technology that uses thin film transistor technology to control the individual pixels on the screen. This allows for faster response times, better color reproduction, and higher resolution compared to other display technologies. TFT monitors are commonly used in laptops, computer monitors, and televisions.
