A utilização de redes informáticas tem crescido muito nos últimos anos, e as organizações e instituições começaram a criar redes. Cada rede informática deve ser concebida e implementada de acordo com as condições e polÃticas de cada organização. De facto, as redes informáticas fornecem a infraestrutura necessária para a partilha de recursos na organização. Se estas infra-estruturas não forem concebidas corretamente, surgirão diversos problemas na utilização da rede e será necessário gastar muito dinheiro para a manter e adaptar à s necessidades pretendidas. Em geral, antes da conceção fÃsica de uma rede informática, as necessidades devem ser identificadas e analisadas em primeiro lugar, por exemplo, por que razão pretendemos criar uma rede numa biblioteca e que serviços esta rede deve prestar. Que acções devem ser tomadas para fornecer os serviços e os serviços desejados pela maioria dos utilizadores. Questões como o protocolo desejado para utilizar a rede, a velocidade da rede e, mais importante, as questões de segurança da rede, cada uma delas deve ser cuidadosamente examinada. Tentou-se, depois de apresentar as definições básicas, fornecer material sobre as suas aplicações práticas, para ajudar numa melhor tomada de decisão.
