ELI5: Explain Like I'm 5

Simple File Transfer Protocol

Okay, so imagine you have a toy car that you want to give to your friend who lives across the street. But instead of walking across the street to give it to them, you want to send it to them through a special tube.

This is sort of like the Simple File Transfer Protocol (SFTP), which is a way for computers to send files to each other over the internet. It's like a special tube that connects your computer to your friend's computer.

When you want to send a file to your friend using SFTP, you have to follow a few simple steps:

1. First, you have to make sure that your friend's computer is ready to receive files using SFTP. Your friend will have to give you something called an "IP address" and a "username" and "password" that will let you connect to their computer.

2. Next, you have to find the file you want to send. It's sort of like finding the toy car you want to send to your friend. You have to know where it is on your computer and what it's called.

3. Then, you have to start up the SFTP program on your computer. This is like turning on the special tube that will let you send the file to your friend's computer.

4. Once you're connected to your friend's computer using SFTP, you can select the file you want to send and tell your computer to start transferring it. This is sort of like dropping the toy car into the tube.

5. Finally, your computer will send the file to your friend's computer through the SFTP connection. This is like the toy car being sent across the street through the special tube.

That's it! That's how SFTP works. It's like a special tube that lets you send files to your friends' computers over the internet.
