1. USB stands for:

Universal Serial Bus.

Universal Swappable Bus.

Universal System Bar.

Universal Series Bus.

USB stands for Universal Serial Bus. This is a widely used technology for connecting devices to a computer. It provides a standardized connection and allows for the transfer of data and power between devices. The term "serial" refers to the fact that data is transmitted one bit at a time, while "bus" refers to a shared pathway for data transfer. The other options, Universal Swappable Bus, Universal System Bar, and Universal Series Bus, do not accurately describe the acronym USB.

2. LCD stands for

Liquid cathode display.

Liquid crystal display.

Lumens and crystal display

Laser compact display.

The correct answer is "liquid crystal display." LCD stands for liquid crystal display, which is a type of flat panel display commonly used in electronic devices such as televisions, computer monitors, and smartphones. It uses liquid crystals to produce images by manipulating the light passing through them. The term "liquid cathode display" and the other options mentioned are incorrect and do not accurately represent the acronym LCD.

3. Laser printers require ________ to produce printed documents.

Toner powder

Toner ink

Liquid ink

Laser printers require toner powder to produce printed documents. Toner powder is a fine, dry substance that is used in laser printers to create the text and images on the paper. It is made up of a mixture of plastic particles and pigments, which are attracted to the electrostatic charge created by the laser printer. As the toner powder is transferred onto the paper, it is fused onto the surface using heat, resulting in the final printed document.

4. Which of the following is TRUE about monitors?

CRT monitors are usually lighter-weight than LCDs

The more pixels, the lower resolution.

LCD panels have virtually replaced CRT display screens.

LCDs use a large glass tube.

The given statement is true because LCD panels have become the dominant technology in the display screen industry, replacing CRT monitors. CRT monitors, which used cathode ray tubes, have become less common due to their bulkiness, higher power consumption, and lower image quality compared to LCD panels. LCD panels offer several advantages such as thinner profiles, lower power consumption, higher resolution, and better image quality, making them the preferred choice for most applications.
