It is difficult for many students to master basic concepts in computer science and programming. A large portion of the confusion can be blamed on the complexity of the tools and materials that are traditionally used to teach Computer Science.

Perhaps the greatest source of complexity in introductory Computer Science courses is the use of traditional systems languages such as C++ and Java. These languages evolved to solve problems that arise in large-scale programming where the primary emphasis is on structure and discipline. They were not designed to make writing small or medium-scale programs easy. The recent rise in popularity (in industry, if not necessarily in academia) of scripting languages, such as Python, suggests an alternative. Python is flexible and makes experimentation easy. Solutions to simple problems are simply and elegantly expressed.

Python is a natural choice as a first programming language because its basic structures are very clean and well-designed. The concepts carry over directly to subsequent study of systems languages such as Java and C++. Python is a real-world language that is available for virtually every programming platform and comes standard with its own easy-to-use integrated programming environment. Python allows students to focus on the primary skills of algorithmic thinking and program design without getting caught up in mysterious language details.

Analise o trecho de código abaixo e assinale a alternativa que corresponde ao seu propósito.

Em Banco de Dados, necessitamos ser mais precisos sobre o que significa um "término bem sucedido" de uma transação. Para tanto, estabelecemos um modelo abstrato simples. Uma transação deve ser feita em um dos seguintes estados, com seus respectivos conceitos:

No LINUX, há comandos que seguem fases e que são as ações executadas pelo usuário em um terminal de recepção, tendo como objetivo a execução de uma ação ou processo. Acerca disso, considere as afirmativas abaixo:

1.A fase inicial, em que um comando é inscrito no terminal, tem como pré-requisito que o operador saiba quando (situação) e qual (sintaxe) comando utilizar, e que o mesmo comando, sob a forma requisitada, esteja presente no sistema operacional.

2.A fase intermediária, ou de processamento, é aquela em que a requisição do usuário é enviada ao interpretador de comandos (shell) e daí para o kernel do sistema operacional.

3.A fase final ou de saída é aquela em que é mostrado o resultado ou produto do comando, seja na tela do terminal, ou em qualquer outra forma de saída, por meio de manipulação de serviços ou processos.

4.No LINUX, o comando ls seguido do nome do arquivo permite a visualização de seu conteúdo, porém só funciona para arquivos do tipo texto (.txt).

5.No LINUX, o comando dir é, na verdade, um port (adaptação) do comando de mesmo nome que há no UNIX, o qual, por sua vez, foi adotado pelo MS-DOS.

Assinale a alternativa correta.
