## Summary
A **live distribution** is an operating system that runs directly from removable media (such as CD, DVD, or USB) without requiring installation on a hard disk. It allows users to boot and use a fully functional OS without modifying the host system's storage.

## Key Facts
- A live distribution is a type of **operating system** that boots and runs from removable media.
- It does not require installation on a hard disk, making it portable and non-invasive.
- Common media include **CDs, DVDs, and USB drives**.
- Examples include **NomadBSD** (FreeBSD-based), **AbulÉdu Live**, and **Frenzy BSD**.
- Related to **Live CD** and **Live USB** distributions.
- Classified under **Category:Operating system distributions bootable from read-only media**.
- Aliases include **"live distro"**.
- Wikidata sitelink count: **2** (French and Dutch Wikipedia).

## FAQs
### Q: What is a live distribution used for?
A: Live distributions are used for **testing operating systems, data recovery, system repairs, or running a portable OS** without installing anything on the host machine.

### Q: Can a live distribution save changes?
A: Some live distributions allow **persistence** (saving changes to the USB or other media), but many run entirely in memory without saving data.

### Q: What are some examples of live distributions?
A: Notable examples include **NomadBSD (FreeBSD-based), AbulÉdu Live (educational), and Frenzy BSD**.

### Q: Is a live distribution the same as a Live CD?
A: A **Live CD** is a specific type of live distribution that boots from optical media, while live distributions can also run from **USB drives or other removable storage**.

### Q: Do live distributions work on any computer?
A: Most live distributions are **hardware-independent** but may require **BIOS/UEFI boot support** and sufficient RAM to run efficiently.

## Why It Matters
Live distributions provide a **portable, non-destructive way to use an operating system** without altering the host machine’s storage. They are invaluable for **system recovery, cybersecurity testing, privacy-focused computing, and educational environments**. By running entirely from removable media, they allow users to **test new OS versions, rescue corrupted systems, or securely browse the web** without leaving traces. Their flexibility makes them essential tools for IT professionals, educators, and privacy-conscious users.

## Notable For
- **Portability**: Runs from removable media without installation.
- **Non-invasive**: Does not modify the host system’s hard drive.
- **Versatility**: Used for **system recovery, testing, and secure computing**.
- **Examples**: Includes **NomadBSD, AbulÉdu Live, and Frenzy BSD**.
- **Related Technologies**: Closely tied to **Live CD and Live USB** distributions.

## Body
### Definition and Functionality
A **live distribution** is an operating system designed to boot and run directly from **removable media** (CD, DVD, USB) without requiring installation on a hard disk. It loads the entire OS into **RAM**, allowing users to interact with a fully functional system without modifying the host machine’s storage.

### Types of Live Distributions
- **Live CD**: Boots from optical media (CD/DVD).
- **Live USB**: Boots from USB flash drives or external hard disks.
- **Specialized Distributions**: Some are tailored for **education (AbulÉdu Live), security, or system recovery**.

### Use Cases
- **System Recovery**: Used to repair or rescue corrupted systems.
- **Testing**: Allows users to trial an OS before installation.
- **Privacy & Security**: Leaves no traces on the host machine.
- **Portable Computing**: Enables carrying a full OS in a pocket.

### Technical Details
- **Persistence**: Some live distributions support saving changes to the media.
- **Hardware Requirements**: Typically needs **sufficient RAM** to run efficiently.
- **Boot Methods**: Supports **BIOS/UEFI booting** depending on the distribution.

### Related Entities
- **NomadBSD**: A FreeBSD-based live USB OS.
- **AbulÉdu Live**: A free virtual learning environment.
- **Frenzy BSD**: A live distribution based on FreeBSD.
