What technological advancement significantly impacted information processing in the late 20th century?

The significant technological advancement that transformed information processing in the late 20th century is personal computers. This innovation revolutionized how individuals and businesses managed, processed, and communicated information. With the introduction of user-friendly interfaces and powerful software applications, personal computers made computing accessible to the general public and allowed for a wide range of tasks—such as word processing, data analysis, and programming—that were previously confined to larger mainframe systems.

The impact of personal computers was profound; they laid the groundwork for the digital age by enabling people to carry out complex tasks at a personal level and facilitated the development of a new economy based on technological literacy. As a result, they became essential tools in both professional and personal environments.

While global positioning systems, the internet, and artificial intelligence have all played important roles in technological advancement, personal computers were foundational to information processing developments during that period, making them a crucial milestone in the evolution of technology.
