Headers and footers are inserted in documents to display information such as page numbers, titles, or dates consistently at the top or bottom of each page, especially when printed. This allows important information to appear on every page automatically.

A programmed chip is commonly referred to as a PROM (Programmable Read-Only Memory), which can be programmed once after manufacturing. ROM is a broader category that includes PROM but is not specifically the 'programmed chip' itself.

In Microsoft Word, the 'Split' button is located to the left of the horizontal scroll bar, allowing users to split the document window for easier viewing and editing. The 'View' buttons are typically found at the bottom right corner of the window, not to the left of the horizontal scroll bar.

The term used when a clip art image changes the direction of faces is 'Flip,' which mirrors the image horizontally or vertically. 'Rotate' changes the orientation by turning the image around a point, but does not specifically change the direction of faces as flipping does.

The SUM function in Excel is used to add up all the numeric values within a specified range of cells, making option A correct. Other options describe different functions: AVERAGE calculates the mean, COUNT counts cells with numbers, and MAX finds the highest value.

Supercomputers are designed to perform a limited number of tasks extremely quickly, focusing on high-speed computation for complex calculations. Mainframes, on the other hand, prioritize handling many tasks simultaneously, supporting numerous users and applications concurrently.

The feature that allows you to reverse or take a step backward after making a mistake is called 'Undo'. It reverts the last action performed, making it the correct choice.

The default font size in a new Microsoft Word document based on the Normal template is 12 pt, typically using the Calibri font. This is the standard setting unless the template is modified.

The 'All Caps' feature in Microsoft Word converts all the selected text into uppercase letters, making all characters capitalized. This is a text formatting option and does not relate to images or captions.

Pressing and holding the left mouse button while moving the mouse is called dragging. This action allows you to move objects or select multiple items on the screen.
