RS-232
Hi kiddo! Today we're going to talk about something called RS-232. It's a funny name that stands for Recommended Standard 232.
RS-232 is a way for devices to communicate with each other, kind of like how we use words to talk to each other. But instead of words, RS-232 uses a bunch of electrical signals to send information from one device to another.
Imagine you're playing a game and you want to tell your friend what you're doing. You might use hand gestures to show them what's happening. In the same way, RS-232 uses different patterns of electrical signals to represent different letters, numbers, and symbols.
In order to send these signals, we need a special wire called a serial cable. It has lots of small metal pins that connect to the two devices. Think of it like a telephone line that connects two people so they can talk to each other.
Now, let's talk about how RS-232 works. When you talk, you use your voice to make sounds. In the same way, RS-232 uses electrical signals to send information. These signals are made up of positive or negative voltages, kind of like how light switches have on and off positions.
When a device wants to send information to another device, it sends a stream of these electrical signals down the serial cable. The receiving device then decodes these signals and turns them into the information it was meant to represent.
RS-232 is still used today in some older devices like printers and modems. While it may seem complicated, it's actually a very useful way for devices to communicate with each other. And now you know what RS-232 stands for and how it works!
