The Intel 4004 microprocessor

This resource introduces the Intel 4004, the first CPU on a single silicon chip, and explores its origins in a calculator contract, the shift from a multi‑chip design to the MCS‑4 four‑chip system, and the pivotal role of design expertise and MOS technology. Learners practice reading comprehension, vocabulary pronunciation with audio, cloze activities, speaking prompts, a short video with quizzes, and a grammar focus on future forms, consolidating both technical knowledge and English skills.
