What each word in Vakna means, one page per word, from the glossary.

- [Box](https://vakna.com/docs/concepts/box): What users call a sandbox, in the vakna CLI and anything else they see.
- [Fork](https://vakna.com/docs/concepts/fork): A new box started from a snapshot of another, with the same memory and disk at that moment.
- [Lockdown](https://vakna.com/docs/concepts/lockdown): The egress posture every box starts in, where a box reaches only the hosts you allow, through Vakna's proxy.
- [Receipt](https://vakna.com/docs/concepts/receipt): What a box or a task cost, and what the platform did to run it, line by line.
- [Snapshot](https://vakna.com/docs/concepts/snapshot): A point-in-time image of a box, its memory and its disk, that new boxes fork from.
- [Suspend](https://vakna.com/docs/concepts/suspend): To pause a box with its processes, memory and ports intact, so compute stops billing until it resumes.
- [Task](https://vakna.com/docs/concepts/task): A named group of boxes running one command, with one receipt for the lot.
