Intel coupled the RAM chip with the microprocessor, allowing fourth generation computers to be smaller and faster than prior computers. The 4004 was only capable of 60,000 instructions per second, but its successors brought ever-growing speed and power to computers, including the Intel 8008, 8080 (used in many computers using the CP/M operating ...
Computers built after 1972 are often called fourth-generation computers, based on LSI (Large Scale Integration) of circuits (such as microprocessors) – typically 500 or more components on a chip. Later developments include VLSI (Very Large Scale Integration) of integrated circuits 5 years later – typically 10,000 components.
A fourth-generation programming language (4GL) is a high-level computer programming language that belongs to a class of languages envisioned as an advancement upon third-generation programming languages (3GL).
Most constraint-based and logic programming languages and some other declarative languages are fifth-generation languages. While fourth-generation programming languages are designed to build specific programs, fifth-generation languages are designed to make the computer solve a given problem without the programmer. This way, the user only needs ...
The "fourth-generation" of digital electronic computers used microprocessors as the basis of their logic. The microprocessor has origins in the MOS integrated circuit (MOS IC) chip. [ 176 ] Due to rapid MOSFET scaling , MOS IC chips rapidly increased in complexity at a rate predicted by Moore's law , leading to large-scale integration (LSI ...
What allowed LINC to make programmers much more efficient and the application systems they produced easier to read and maintain, and differentiated it from being simply yet another third generation high level language, was LINC's assumption, use of, and total reliance on all of the facilities available, and packaged, with the Burroughs computer ...

The fourth generation computers began with the shipment of CPS-1, the first commercial microprocessor microcomputer in 1972 and for the purposes of this list marks the end of the "early" third generation computer era. Note that third generation computers were offered well into the 1990s. The list is organized by delivery year to customers or ...
