ELECTRONIC EMAIL














?What is email and how do you use it
Email - also known as electronic mail - is a system designed to allow people to send messages to one another using the Internet. In fact, using email is a little like sending letters through the post.
Email addresses perform the same function as street addresses. They are used by Internet mail servers (the electronic equivalent of post offices) to determine where to send the email.
A person's email address consists of three parts, their username, an @ symbol, and a domain name.
username@domain.com.au
There are four easy steps to sending an email:

Enter in the recipient's address.

Enter a subject title to let the person receiving your email know what the email is about.

Write the content of the email.

Press the send button.
If you correctly address your email, it may only take five seconds or so for your email message to leave your computer and be delivered to the recipient's email provider.
If the recipient is online at the time, they should receive the email immediately. However if they are not online, it will remain in the recipient's
inbox until the next time they check their mail.
How can you get an email account?
When you sign up with an
Internet service provider (ISP), you will be given an Internet email account.
Most ISPs provide you with a CD or detailed instructions on how to adjust your computer's settings to use email. Some ISPs will even visit your home or office and set the email up for you.
You will be given a
username and a password to allow you to access your email account. You will need to enter your username and password to send or receive emails.
If you do not have email software on your computer you can access a variety of websites that offer free Internet-based email accounts. The advantage of web-based email is that you can access your emails from anywhere in the world.
On your computer you may already have email software such as Microsoft® Outlook Express. Your ISP will give you instructions on how to set this up to send and receive emails. If you have this type of email software, you can only send and receive emails with this account from your computer.
Examples of free web-based email are:
Hotmail ®, one of the best known providers of free email accounts.
Yahoo, a site that offers free email accounts.
What are email attachments?
Most modern email programs allow you to send additional files as an
attachment to an email message.
Attachments are separate files that are sent along with your email message. They do not form part of your email message but they can be opened and viewed or edited by the email recipient.
You can attach all sorts of files to an email including spreadsheets, word processed documents, database files, even sound recordings and graphic images.
In order to view an attached file the recipient needs to have a copy of the software application that was used to create the attachment initially. For example, if you send a friend a Microsoft® Excel document as an email attachment, then your friend must have Microsoft® Excel installed to read the attachment.

?Are your emails secure
Unfortunately your emails are not secure. Every email
server on the Internet is managed by an Administrator, a person who makes sure that the email server is running smoothly.
Just like ordinary mail, emails can get lost or get sent to the wrong address. When that happens the administrator may need to open an email to try and find out where it should go, or in some cases send it back to the sender.
To do this, email administrators have a special password that allows them to read another person's email, but they rarely abuse this power and it is really only for use in emergencies.
Because the email server keeps a permanent record of emails, even if you delete an email from your computer the administrator will still be able to access the email if required.
Lots of people access the Internet for lots of different reasons, and while most people use the Internet responsibly, others use it to carry out illegal activities. These people are called
hackers.
Among other things, hackers try an intercept emails as they are being transmitted over the net, in the hope of finding something of interest, or perhaps something they can use for their own purposes.
For this reason you should always take care when emailing personal information over the Internet, and never email your financial details to anybody.
