In the late 1960’s, the United States Department of Defense developed the Internet as a military research project. At that time, this project was not even referred to as the “Internet”. It was known as ARPANET. Its purpose was to create an emergency military communication system that could withstand a nuclear attack.
Gradually over the years, ARPANET was employed in major universities and later on by scholars and scientists. As the years went by, the network quickly grew to include researchers across the country and eventually included schools, businesses, organizations and individuals around the world.
Now, people all across the world are networked together as a result of the Internet!
An email is very similar to a written letter. You write your message and then you send it. However, an email is completely digital and you don’t have to use any stamps or go to the post office!
The benefits of using email are numerous. Most importantly, it’s a free form of communication and many people and businesses utilize email and so should you.
Many people simply logon to the Internet only to check their emails or to send an email message to someone else. Email is a very important tool that you need to take advantage of.
A sample email address looks like the following: email@example.com
Every email address has four different parts. First, there is the person’s name or nickname. For example, the “yourname” part of the email address above is your name/nickname. The second part of an email address is the famous @ sign. Anyone and everyone who has an email address will have this famous @ sign. The @ stands for “at”! The third part of an email address is the domain where the email account is registered with. For example, “somedomain.com” is the domain where the “yourname” email account is registered with.
An Internet virus is a program or piece of code that is loaded onto your computer system and does harmful things against your wishes. All computer viruses are man made. A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it can quickly use all your computer’s available memory and bring your computer to a dead halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.
An Internet virus attaches itself to a program or file on your computer so it can spread from one computer to another, leaving infections as it travels. Much like human viruses, computer viruses can range in severity; some viruses cause only mildly annoying effects while others can damage your hardware, software, or files. A virus may exist on your computer but it cannot infect your computer unless you run or open the infected program. It is important to note that a virus cannot be spread without a human action, (such as running an infected program) to keep it going. People continue the spread of a computer virus, mostly unknowingly, by sharing infecting files or sending emails with viruses as attachments in the e-mail.
As a safety precaution, we highly recommend that you have some type of virus protection installed on your computer before you consider downloading anything.
