๐ Topic Summary
Text representation is how we convert human-readable text into a format that computers can understand (encoding) and back again (decoding). This process is crucial for storing, transmitting, and processing text data. In this activity, we'll explore basic encoding and decoding methods without using any electronic devices, giving you a hands-on understanding of these fundamental concepts. Think of it like creating your own secret code! ๐
