| ## BSD operating system
 | |
| 
 | |
| 
 | |
| 
 | |
| ### Overview
 | |
| 
 | |
| Berkeley Software Distribution (BSD) is a group of related open source Unix-like operating systems (OS) with origins in early versions of Research Unix at Bell Labs.
 | |
| FreeBSD is the most popular member.
 | |
| BSD is developed by Berkeley Software Design, Inc., written in C language.
 | |
| BSD is configured for internet hosting, web hosting, and hosting many servers on one system.
 | |
| It is the first OS to have added an internet protocol.
 | |
| BSD OSes have a very strongly enforced time-sharing system, which makes them most useful where resources are shared between processes.
 | |
| As a comparison, the Linux OS is known to be preferred for single-task processes such as supercomputers and desktops.
 | |
| Effectively, the BSD multi-tasking forced-interrupt part of timesharing gets in the way of dedicated single processes.
 | |
| 
 | |
| BSD includes a 'Jails' system which is somewhat analogous to Linux Containers -- except with additional security and flexibility in implementation.
 | |
| 
 | |
| ### BSD Versions
 | |
| 
 | |
| In contrast to the numerous Linux distributions, there are only four major open source BSDs. Each BSD project maintains its own source tree and its own kernel.
 | |
| 
 | |
| 1. FreeBSD
 | |
| 2. NetBSD
 | |
| 3. OpenBSD
 | |
| 4. DragonFlyBSD
 | |
