&nbsp;Unix&nbsp;&nbsp; 



O que é unix?

É um sistema operacional, um
conjunto de programas projetados para controlar as interações das funções de
baixo nível com as aplicações
(programas) e com os usuários. O Unix controla os recursos do computador,
distribui as tarefas entre os diferentes usuários, controla a ordem das
tarefas. Sua estrutura pode ser visualizada pela figura.

A história do unix?

O Unix foi criado no final da década de 1960 e início de
1970, em uma época em que os computadores eram grandes, caros e de difícil
acesso a pessoas comuns. Havia poucos computadores e vários pesquisadores
necessitando dos recursos destes para poderem dar andamento aos seus trabalhos,
e os sistemas operacionais da época não satisfaziam às necessidades desses
profissionais. Era então, imprescindível desenvolver um sistema operacional
multiusuário, multitarefa, que pudesse ser convertido para diferentes
plataformas de hardware. 

Quem criou a unix?

Originalmente criado por Ken Thompson. 

O codigo unix é aberto ou
fechado?

O unix é um codigo fechado.

Quanto custa o código unix?

O seu custo eablets, desktop, smartphone,
servidores, etc ra de US$ 129 para uma única licença de usuário e US$ 199 para
um dólares.



Memoria Ram: 512mb
Placa de Video: 64mb
HD: 12gb
Placa de Som: onboard
Quais são os reqiusitos do sistema?
windows 7 starter num tem aero e e limitado a 3 programas de cada vez! 

Onde é usado o unix?

Tablets, desktop, smartphone, servidores, etc.

Quais são as vantagens e as
desvantagens da unix?

A 4Linux - tradicional parceira do Software Livre, estará
promovendo um treinamento inédito sobre o “Bacula”. As primeiras turmas
ocorrerão em Maio/2009, na cidade de São Paulo-SP.
O curso será ministrado pelo autor deste “blog”, Heitor Medrado de Faria. E
maiores informações, podem ser conseguidas através deste link.
Tenho certeza que será ótimo (apesar de que sou suspeito para falar… rs).
