b) Microprocessor

The invention of the microprocessor was a groundbreaking development crucial in advancing computing. It miniaturized and integrated the functions of a central processing unit (CPU) onto a single chip, revolutionizing computer design and manufacturing. Introduced in the early 1970s, microprocessors led to the development of smaller, more powerful, and more affordable computers, paving the way for the personal computer revolution. This technology has had a profound impact on various industries, from computing and telecommunications to automation and beyond, fundamentally changing the way we interact with technology.
