Similarly, in the case of paragraphs, borders can be applied to create a box around the entire paragraph or to underline it. Therefore, the correct answer is "All of the above" as borders can be applied to all these elements.

The flat surface of a plotter is called a "bed." This term is commonly used in the context of plotters, which are devices used for drawing or printing large-scale graphics or designs. The bed refers to the flat area where the paper or material to be plotted is placed and held in position during the plotting process. It provides a stable and level surface for accurate and precise plotting.

The drum in a laser printer plays a crucial role in transferring toner to the paper. When a laser printer receives a print job, the laser creates a static charge pattern on the drum that matches the image or text. Toner powder sticks to the charged areas on the drum, which then rolls over the paper, transferring the toner in the correct pattern. The fuser later melts the toner onto the paper to complete the printing process.
