Email, also known as electronic mail or E-mail, is a popular way to send messages quickly and inexpensively nowadays. It works like sending letters using a computer. When someone wants to send a message, they type it on their computer and choose who should receive it. The message doesn't go right away. Instead, it waits until the person it's meant for is ready to read it. This means the sender and receiver don't have to be online at the same time.
In this system, it's like the sender is calling the recipient's computer. They keep trying until they get a connection. Once they're connected, the sender's computer sends the message to the receiver's computer really fast. The special thing is that the sender and receiver don't have to be in the same place – they can be far away from each other.
The message stays in the receiver's computer until they read it. Email messages can travel through phone lines, satellites, or undersea cables. There are many good things about email:
- It doesn't cost much: Sending emails is cheaper than using other methods.
- It's quick: Messages get to the other person in a short time.
- No need to be there: The sender and receiver don't need to be online at the same time.
- It's fast: Email is faster than sending faxes or telex messages.
- It's secure: You can use a password to keep your messages safe
