Comunicado 23 Técnico
Comunicado 23 ISSN 1415-2118 Abril, 2007 Técnico Campinas, SP Armazenagem e transporte de arquivos extensos André Luiz dos Santos Furtado Fernando Antônio de Pádua Paim Resumo O crescimento no volume de informações transportadas por um mesmo indivíduo ou por uma equipe é uma tendência mundial e a cada dia somos confrontados com mídias de maior capacidade de armazenamento de dados. O objetivo desse comunicado é explorar algumas possibilidades destinadas a permitir a divisão e o transporte de arquivos de grande volume. Neste comunicado, tutoriais para o Winrar, 7-zip, ALZip, programas destinados a compactação de arquivos, são apresentados. É descrita a utilização do Hjsplit, software livre, que permite a divisão de arquivos. Adicionalmente, são apresentados dois sites, o rapidshare e o mediafire, destinados ao compartilhamento e à hospedagem de arquivos. 1. Introdução O crescimento no volume de informações transportadas por um mesmo indivíduo ou por uma equipe é uma tendência mundial. No início da década de 90, mesmo nos países desenvolvidos, um computador com capacidade de armazenamento de 12 GB era inovador. As fitas magnéticas foram substituídas a partir do anos 50, quando a IBM lançou o primogenitor dos atuais discos rígidos, o RAMAC Computer, com a capacidade de 5 MB, pesando aproximadamente uma tonelada (ESTADO DE SÃO PAULO, 2006; PCWORLD, 2006) (Figs. 1 e 2). Figura 1 - Transporte do disco rígido do RAMAC Computer criado pela IBM em 1956, com a capacidade de 5 MB. 2 Figura 2 - Sala de operação do RAMAC Computer. Após três décadas, os primeiros computadores pessoais possuíam discos rígidos com capacidade significativamente superior ao RAMAC, algo em torno de 10 MB, consumiam menos energia, custavam menos e, obviamente, tinham uma massa que não alcançava 100 quilogramas.
