Analise o texto a seguir:
The Internet has become such an integral part of our lives, with such powerful capabilities, that it is easy to forget that this technological marvel was created by the long, hard, dedicated efforts of human beings – folks who had a vision of what universal networking could become and worked to make it happen. The key people, projects, and organizations that helped create the Internet are described below, first in a top-level summary and then in sections in roughly chronological order.

Considere o texto a seguir:
We should point out here that the focal point of any operating system is its ‘kernel’. Without going into great detail, the kernel is what tells the big chip that controls your computer to do what you want the program that you’re using to do. To use a metaphor, if you go to your favorite Italian restaurant and order ‘Spaghetti alla Bolognese’, this dish is like your operating system. There are a lot of things that go into making that dish like pasta, tomato sauce, meatballs and cheese. Well, the kernel is like the pasta. Without pasta, that dish doesn’t exist. You might as well find some bread and make a sandwich. A plate of just pasta is fairly unappetizing.
Without a kernel, an operating system doesn’t exist. Without programs, a kernel is useless.

Historically, information security has been called a number of different things such as:
• Data security;
• IT Security;
• Computer security.
But these terms (except possibly data security) ignore the fact that the information that is held on the computers is almost always and most certainly worth many times more than the computers that it runs on. The correct term is ‘information security’ and typically information security comprises three component parts:
• Confidentiality. Assurance that information is shared only among authorised persons or organisations. Breaches of confidentiality can occur when data is not handled in a manner appropriate to safeguard the confidentiality of the information concerned. Such disclosure can take place by word of mouth, by printing, copying, e-mailing or creating documents and other data etc.;
• Integrity. Assurance that the information is authentic and complete. Ensuring that information can be relied upon to be sufficiently accurate for its purpose. The term ‘integrity’ is used frequently when considering information security as it represents one of the primary indicators of information security (or lack of it). The integrity of data is not only whether the data is ‘correct’, but whether it can be trusted and relied upon;
• Availability. Assurance that the systems responsible for delivering, storing and processing information are accessible when needed, by those who need them.
