WAN stands for Wide Area Network, which is a telecommunications network that extends over a large geographical area, connecting multiple smaller networks such as LANs.

An assembler is a translator that converts assembly language programs into machine language code, which can be executed by a computer's CPU. This distinguishes it from compilers and interpreters, which work with higher-level languages, and debuggers, which are used for testing and debugging code.

DMA stands for Direct Memory Access, a feature that allows hardware subsystems to access main system memory independently of the CPU, improving data transfer efficiency.

In Microsoft Word, cross-references are inserted as Word fields, which dynamically link to other parts of the document such as headings, figures, or tables. This allows the referenced content to update automatically if it changes.

The Document Outline View in MS Word displays the structure of the document based on headings at various levels, allowing users to easily navigate and organize content hierarchically.

Virtual memory is a memory management technique that uses a portion of the hard drive to extend the apparent amount of RAM available to programs. It is typically located on the hard drive, not in RAM, CPU, or flash memory.

URL stands for Uniform Resource Locator, which is the correct and widely accepted full form used to specify addresses on the internet.

The "I Love You" virus, also known as the Love Bug, is widely recognized as one of the most widespread and damaging computer viruses in history, infecting millions of computers worldwide in 2000. It spread rapidly via email, causing extensive damage and making it the record holder for widespread infection.

A USB drive is considered a secondary storage device because it is used to store data externally and persistently, unlike primary storage which is typically volatile memory like RAM. Secondary storage devices retain data even when the computer is turned off.

A slide-title master pair in PowerPoint refers to a combination of a slide master and its associated title master that together define the layout and design for a specific template. This pairing controls the formatting of both the slide content and the title area consistently.
