Data transmission
Data transmission is like sending a message from one person to another person, but instead of using our voices, we use computers and machines to send information. Just like how you send a message by telling your friend what you want to say, we use computers and machines to send information from one place to another.
Say you want to send a message to your friend, but you're not close to them, so you can't just talk to them. What do you do? You write a letter! You put your words on a piece of paper and send it to your friend through the mail.
Data transmission works kind of like that. We can think of all the information we want to send as our message, and the computer or machine we are using to send it as the piece of paper.
First, the information needs to be changed into a special code that computers can read. This is called encoding or formatting the data. Then, the data is sent through wires or wireless signals to another computer or machine. This is like putting the letter in the mailbox.
The receiving computer or machine then takes the encoded data and turns it back into the original message, which is called decoding or deformatting the data. This is like your friend opening the letter and reading what you wrote!
There are many different methods of data transmission, such as wired methods like cables and wireless methods like Wi-Fi or Bluetooth. Each method has its strengths and weaknesses, but they all work in a similar way to get our messages from one place to another.
