O                                                                    linux é Um sistema operacional Unix, multiusuário, multitarefa e multiprocessador, de livre distribuição, disponível para equipamentos x86 (Intel e compatíveis), Motorola 68K, Digital Alpha, Sparc, Mips e PowerPC. É uma implementação aderente ao POSIX- Portable Operating System Interface, ou seja , segue as indicações do IEEE para sistema abertos e portabilidade.&nbsp;Seu sistema operacional é uma coleção de programas que inialiaza o hardware do computador fornecendo rotinas para o controle de dispositivos e ainda fornece gerência, escalonamento e interação de tarefas além de manter a integridade de sistemas. O Linux é&nbsp; utilizado por que possui os mais modernos sistemas operacionais como: multiusuários que significa muitas pessoas acessando o sistema ao mesmo tempo e ainda permitir que várias tarefas sejam executadas, além disso possui memória virtual, biblioteca compartilhada,gerenciamento próprio de memória, interface gráfica X Windows e oferece recursos de ultima geração.Este programa surgiu do passatempo de um estudante de ciências da computação da Universidade de Helsinki, Linux Torvalds que se inspirou no Minix um pequeno sistema Unix. E o nome Linux surgiu da mistura de Linus + Unix.O Linux por sua vez e vantajoso por ter baixo custo, segurança e comunidade de suporte ativa, mas isso não quer dizer que não apresente desvantagens tais como incompatibilidade com certos equipamentos e formatos proprietários.
