Definition: FreeBSD 7.0 was a free operating system released in 1998. It was known for its low cost, open-source nature, and extensive support for applications like Unix shell scripts, file manipulation tools, and other utilities. FreeBSD was originally written in C but later added some GNU components to enhance portability across different platforms. It remained popular as a free alternative to the proprietary BSD operating system until the release of FreeBSD 9.0 in 2004.
