“The Internet”
The Internet began in the Eighties. Today it has grown to become a major means of communication. Websites and emails, things that were unheard of just two decades ago, are quickly gaining in popularity and usage.
Via a computer, a person can access the Internet and the numerous websites in it. There are websites on just about anything anyone can think of. Information, files, photographs, video clips, computer software, games etc can often be obtained free or for a fee from some websites. Online shopping, banking and other services make it a cinch for an ordinary person to perform regular chores from the comfort of home or office.
A very popular feature of the Internet is the use of email. Using email, persons at any part of the world can communicate with one other in an instant. The cost of sending an email is almost nothing. On top of that, files and pictures can be attached and sent together with the email.
Despite its obvious usefulness, negative things are also present on the Internet. Viruses, worms, Trojan horses and other harmful programs wait to strike at the unwary user. Accessing the Internet without the protection of an anti-virus program or firewall is a sure way of getting infected. The result of infection varies from a simple obscene message on the screen to the complete erasure of the files and records in the computer.
Using the Internet is no different from dealing with our daily living in the physical world. We sue it but we take precautions to avoid the obvious dangers and negative elements in it.
