Explain the uses of a mouse, differences between hard/soft boot, functions of antivirus, logical/physical formatting, and CPU/RAM.

Here are the explanations for the listed topics: • Uses of a mouse: A mouse is used to point at items on a screen, click to select or activate them, drag items to move them, and scroll through documents or web pages. • Difference between hard & soft boot: A hard boot* (or cold boot) is when a computer is started from a completely powered-off state. A soft boot* (or warm boot) is when a computer is restarted while it is already running, without completely cutting power. • Functions of an antivirus: An antivirus program is designed to detect, prevent, and remove malicious software (malware) such as viruses, worms, and Trojans from a computer system. • Difference between logical & physical formatting: Physical formatting* (low-level formatting) is the process of dividing a disk into tracks and sectors, creating the basic physical structure for data storage. Logical formatting* (high-level formatting) is the process of creating a file system on a disk, which allows the operating system to store and retrieve files. • Difference between CPU and RAM: The CPU (Central Processing Unit)* is the "brain" of the computer, responsible for executing instructions and performing calculations. RAM (Random Access Memory)* is a type of volatile memory used for temporary storage of data and programs that the CPU is actively using, allowing for quick access. • Difference between Digital & Web Camera: A digital camera* is a standalone device primarily used to capture still photographs and often video, storing them on internal memory or memory cards. A web camera* (webcam) is typically connected to a computer and is primarily used for live video communication over the internet. • Functions of RAM & RDM: RAM (Random Access Memory)* functions as a temporary workspace for the CPU, holding data and instructions that are currently being processed. It is volatile, meaning its contents are lost when power is off. RDM is not a standard computing acronym. If it refers to ROM (Read-Only Memory)*, its function is to store permanent, non-volatile instructions, such as the computer's BIOS, which are essential for startup. • Examples of social media platforms: Examples include Facebook, Instagram, Twitter (X), LinkedIn, and TikTok. • Functions of cut & copy: The copy* function duplicates selected data and places it onto the clipboard, leaving the original data in its place. The cut* function removes selected data from its original location and places it onto the clipboard. • Difference between Internet & Intranet: The Internet* is a global, publicly accessible network of interconnected computer networks. An Intranet* is a private network accessible only to an organization's members, typically used for internal communication and data sharing. • Examples of different computers: super super mainframe: Supercomputers are the fastest and most powerful computers, designed for complex calculations and scientific research (e.g., Fugaku, Frontier*). Mainframes are large, powerful computers used by large organizations for critical applications, bulk data processing, and transaction processing (e.g., IBM Z series*).
