The vast applications of modern computers and the necessity for computer security

But few laymen, even if they were aware of the machines, could see the connection. Experts too, were sceptical. Not only were computers huge, expensive, one-of-a-kind devices designed for performing abstruse scientific and military calculations, such as cracking codes and calculations missile trajectories, they were also extremely difficult to handle.

Computing basics

Now, it is clear that computers are not only here to stay, but they have a profound effect on society as well. They are used to run ordinary household appliances such as televisions and microwaves, to being tools in the workplaces through word processing, spreadsheets, and graphics software, to running monumental tasks such as being the heart and soul of the nations tax processing department, and managing the project timetables of the Space Shuttle.

It is obvious that the computer is now and always will be inexorably linked to our lives, and we have no choice but to accept this technology and learn how to harness its total potential. With any progressing technology, an unauthorized application can almost be found for it.

A computer could and has been used for theft and fraud — for example, as a database and manager of illegal activities such as drug trafficking and pornography. However, we must not just consider the harmful applications of the computer, but also take into account the good that they have caused.

When society embraced the computer technology, we have to treat this as an extension of what we already have at hand. This means that some problems that we had before the computer era may also arise now, in the form where computers are an accessory to a crime. One of the problems that society has faced ever since the dawn of civilization is privacy.

The issue of privacy on the Internet has risen many arguments for and against having it. The issue of privacy has gotten to the point where the government of the United States has placed a bill promoting a single chip to encrypt all private material on the Internet.

Why is privacy so important? Hiding confidential material from intruders does not necessarily mean that what we keep secret it illegal. Since ancient times, people have trusted couriers to carry their messages.

We seal out messages in a envelope when sending mail through the postal service. Using computer and encrypting programs to transfer electronic messages securely is not different from sending a letter the old-fashioned way.

Therefore, with any type of new technology, this will argue that the application of cryptography for civilian purposes is not just a right, but is also a necessity. Computer security experts consider it best and most practical way to protect computer data from unauthorized disclosure when transmitted and even when stored on a disk, tape, of the magnetic strip of a credit card.

Two encryption systems have led the way in the modern era. One is the single-key system, in which data is both encrypted and decrypted with the same key, a sequence of eight numbers, each between 0 and The other is a 2-key system in this approach to cryptography, a pair of mathematically complementary keys, each containing as many as digits, are used for encryptions and decryption.Finally, the term computer technology is meant to be inclusive of any device that is essentially controlled by a basic computer (CPU, program, etc.).
