Tipos de Memória Flash

Memórias Flash
Dispositivos de armazenamento electrónico.

O que é a memória flash?

A memória flash é um chip semicondutor, que permite salvar dados conservando o seu conteúdo, inclusive quando se desliga a bateria e que, além disso, permite a eliminação aplicando-lhe uma carga eléctrica. As memórias flash utilizam-se em vários dispositivos,
tais como computadores portáteis, telemóveis, câmaras fotográficas digitais, computadores pessoais, receptores GPS, equipamentos de rede; e são o meio mais adequado para transportar informação, já que o seu estado sólido as faz resistentes a golpes e vibrações.

Conforme o fabricante/marca, existem actualmente os seguintes tipos:

PC Card (PCMCIA) Adaptador para determinado cartão de memória
Compact flash
Smart Media
Memory Stick
Multimedia Card (MMC)
Secure Digital Card
XD Picture Card
Memória Flash USB

Para se poder descarregar os ficheiros no computador necessitamos de ter um "Card Reader"
leitor de cartões de memória.

Num próximo artigo vamos descriminar cada um deles.

My friend and I were recently discussing about how modern society has evolved to become so integrated with technology. Reading this post makes me think back to that debate we had, and just how inseparable from electronics we have all become.


I don't mean this in a bad way, of course! Ethical concerns aside... I just hope that as memory becomes less expensive, the possibility of transferring our brains onto a digital medium becomes a true reality. It's one of the things I really wish I could encounter in my lifetime.

Hey People

I wanted to share with you a great site I just came across teaching [url=http://www.kravmagabootcamp.com][b]Krav Maga[/b][/url] Online If you guys have seen the Tv Show called Fight Quest you would have seen their chief instructor Ran Nakash there featured on their [url=http://www.kravmagabootcamp.com][b]Krav Maga[/b][/url] segment. Anyways, let me know what you think. Is training via the internet something you would do?
