Live CD
A Live CD is a bootable optical disc (CD, DVD, or Blu-ray) that contains a complete operating system and software suite, allowing users to run it directly from the disc without installing it on a computer's hard drive. It loads the OS into RAM and provides full functionality, including applications and drivers, while leaving the host system's storage untouched. This makes it ideal for testing, recovery, or temporary use without altering the existing setup.
Developers should use Live CDs for system recovery, malware removal, or testing new operating systems and software in a safe, isolated environment. They are particularly useful for troubleshooting hardware issues, performing data recovery on corrupted systems, or demonstrating software without installation overhead. In development contexts, Live CDs can serve as portable development environments or for testing cross-platform compatibility.
