Unidade II Data: 31/10/2011Alice Xavier da SilvaVou fazer um breve comentaria da importância da tecnologia já vista no módulo I e sua importância dentro da Educação.Muito se fala nos dias de hoje da globalização, onde a interação e depêndencia dos países se tornam cada vez mais ampla, mais necessária, mais prioritária. Mesmo grades países como os Estados Unidos, França e Grã-Bretanha, não podem se auto-sustentar. Eles dependem de matéria-prima de países considerados de Terceiro Mundo, da mesma forma que estes dependem dos produtos industrializados dos países ricos. Dessa dependência, surgiu a necessidade de evolução no meio de transmissão da informação. Não mais se pode depender de um mensageiro a cavalo para entregar uma mensagem importante. Nos dias de hoje, a informação é constante, crucial e indispensável. Segundos fazem a diferença, e por isso, existe tanta necessidade da tecnologia.Os meios tecnológicos incluem muito mais do que os computadores. Desde o desenvolvimento do telégrafo e as mensagens em código - Morse, o telefone e o advento do celular, aos satélites e a fibra óptica. Mas, o objeto de maior destaque na informação, é a internet. Este meio permitiu uma vasta gama de interação e informação, desde os primórdios do e-mail e dos BBS (Bulletin Board System), onde a internet era algo limitado e com poucos recursos – o que ainda assim, era fantástico – aos dias atuais com o enxame de mensageiros instantâneos, fóruns de informação, áudio e vídeo conferências e compartilhamento da informação, tudo isso a uma velocidade espantosa. Graças à ela, podemos ver, ouvir e falar, com pessoas localizadas no Japão, Estados Unidos, Itália, África do Sul e Rússia, por exemplo, simultâneamente e em tempo real. As inovações em TI (Tecnologia da Informação) permitem um fluxo de informações constante e veloz, para a tomada de decisões cruciais com rapidez e segurança, e por isso, cada vez mais, torna-se parte de nossa vida e indispensável à nossa sobrevivência.Cronologia – Evolução da Tecnologia da Informação (Este é apenas um resumo, com a listagem de alguns fatos marcantes. Uma cronologia completa ocuparia espaço demais, porém, esta é mais que suficiente para o leitor obter uma idéia dos avanços tecnológicos, e se for de seu interesse, poderá pesquisar mais sobre os assuntos aqui descritos.)
