Introduction to BSD

Telugu SystemWithoutTelugu

BSD is a unix-like system- similar to linux. It is a free os and can meet any or almost all requirements of the society. It is a complete system that can be installed solely or together with other operating systems.

There are three varieties- FreeBSD, NetBSD and Open BSD. Of these, Free BSD is the most widespread in use. NetBSD is identical to FreeBSD - and is used mainly for embedded devices. OpenBSD is also similar to FreeBSD - it focusses on security. It is the ideal choice for web servers and internet usage.

We refer to FreeBSD- because it is most widespread and what applies to FreeBSD is pplicable to the other two variants also.

Unlike Linux, FreeBSD is maintained by a centralised group. So there is only one distribution of FreeBSD.There are two versions- stable and current. Stable versions have verified and tested software. Current versions may include latest packages just developed.

Except for few differences in organisation, file system, and mode of installation, FreeBSD is similar to Linux. Packages in standard format- tarfiles zipped - can be installed in FreeBSD also. Almost all the software available can be used under both Linux and FreeBSD. Whatever is applicable to linux is valid for FreeBSD also with some exceptions. These commands and these tips applicable to linux, are applicable to FreeBSD (or NetBSD or OpenBSD) also.
