## 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
|
