fourth-generation computer

Fourth-generation computers, developed in the 1980s and 1990s, are characterized by the use of large-scale integration (LSI) and very large-scale integration (VLSI) technologies. These advancements allowed for the integration of thousands of transistors onto a single silicon chip, leading to the creation of microprocessors and semiconductor memory.1

This generation saw the rise of microcomputers, including the personal computer, making computing power accessible to ordinary consumers. These machines were significantly smaller, faster, and more reliable than their predecessors. The development of microprocessors, essentially a central processing unit on a single chip, was a key innovation of this era.12

Fourth-generation languages (4GLs) also emerged, designed to be more user-friendly and closer to human language than previous programming languages, simplifying tasks for those without formal programming training.3
