Explain how text is sent over the Internet. You may use an analogy or just explain it using words.
Example:
Text is first converted into a binary number using ASCII code. Each letter and symbol has its own number. After that conversion happens, text is sent via the Internet. It might be compressed, turning repeat sequences into shorter segments. Then, it is broken up into packets and sent to its final destination.
This is how this phrase could be compressed.
