The Page Down (PgDn) key in Microsoft Word is used to move the document view and the insertion point down by approximately one screen at a time. It allows users to navigate quickly through long documents without scrolling line by line.
Although its name suggests moving down by an entire page, the key actually advances the view by one screenful, which depends on the current zoom level and window size. The amount moved is therefore based on the visible portion of the document rather than a fixed printed page.
This key is commonly used for fast navigation while reading or editing documents. Conversely, the Page Up (PgUp) key moves the view one screen upward. Understanding the distinction between a screen and a page is important for Microsoft Office examinations.
Correct Answer: Move the cursor one screen down.

A decoder is required for vertical microinstructions because they use an encoded format to save control memory space, which needs to be decoded into individual control signals. Horizontal microinstructions are unencoded.

A NAND (NOT-AND) gate produces an output of logic 0 only when all of its inputs are logic 1. In every other input combination, the output remains logic 1. This behavior makes the NAND gate the inverse of the AND gate.
The NAND gate is one of the most important logic gates in digital electronics because it is a universal gate. Any digital circuit, including all other logic gates, can be constructed using only NAND gates. This makes it widely used in the design of computer processors, memory circuits, and digital control systems.
By contrast, a NOR gate produces logic 1 only when all inputs are logic 0, while an AND gate produces logic 1 only when all inputs are logic 1. Therefore, the description in the question matches the behavior of a NAND gate.
Correct Answer: NAND.
