O QUE SIGNIFICA VIRTUAL MEMORY EM INGLÊS
Memória virtual
Na computação, a memória virtual é uma técnica de gerenciamento de memória que é implementada usando hardware e software. Ele mapeia endereços de memória usados por um programa, chamados de endereços virtuais, em endereços físicos na memória do computador. O armazenamento principal como visto por um processo ou tarefa aparece como um espaço de endereço contíguo ou coleção de segmentos contíguos. O sistema operacional gerencia os espaços de endereço virtual e a atribuição de memória real à memória virtual. O hardware de tradução de endereços na CPU, muitas vezes referido como uma unidade de gerenciamento de memória ou MMU, traduz automaticamente endereços virtuais para endereços físicos. O software dentro do sistema operacional pode estender esses recursos para fornecer um espaço de endereço virtual que pode exceder a capacidade da memória real e, portanto, fazer referência a mais memória do que está fisicamente presente no computador. Os principais benefícios da memória virtual incluem a liberação de aplicativos de ter que gerenciar um espaço de memória compartilhado, aumentar a segurança devido ao isolamento da memória e poder usar conceitualmente mais memória do que estar fisicamente disponível, usando a técnica de paginação.
definição de virtual memory no dicionário inglês
A definição de memória virtual no dicionário é uma forma de aumentar a memória disponível do seu computador ao ampliar os locais na memória onde os dados podem ser armazenados. Os dados armazenados na memória virtual devem ser mapeados de volta para a memória real para serem usados.
