Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the readout technologies?Employed both mechanical pin-based readers and faster optical light-sensing systems
2. What is the technological lineage?A direct precursor to modern digital storage and automated manufacturing systems
3. What is punched tape and how does it work?Punched tape is a long strip of paper with holes that represent data. The pattern of holes tells machines what to do, like a secret code made of holes and spaces.
4. How did punched tape help in telegraphy and long-distance messages?Telegraph systems used punched tape to write messages ahead of time. The tape could then be sent quickly, making long-distance communication faster and more efficient.

Binary Representation: A system of data encoding using only two states, typically represented as 0s and 1s.
Cryptanalysis: The process of analyzing and deciphering encrypted messages or codes.
Read-Only Memory (ROM): A type of computer memory that holds permanent data or instructions, unchangeable after manufacturing.
Numerically Controlled (NC): A manufacturing process where machines are directed by programmed numerical data, often from punched tape.
