Analog computers can have a very wide range of complexity. Slide rules and nomograms are the simplest, while naval gunfire control computers and large hybrid digital/analog computers were among the most complicated. [1] Complex mechanisms for process control and protective relays used analog computation to perform control and protective functions.
The Oslo Analyzer (1938 – 1954) was a mechanical analog differential analyzer, a type of computer, built in Norway from 1938 to 1942. [1] It was the largest computer of its kind in the world when completed. The differential analyzer was based on the same principles as the pioneer machine developed by Vannevar Bush at MIT. [2]
Frontier is anticipated to be operational in 2021 and, with a performance of greater than 1.5 exaflops, should then be the world's most powerful computer. [91] Since June 2019, all TOP500 systems deliver a petaflop or more on the High Performance Linpack (HPL) benchmark, with the entry level to the list now at 1.022 petaflops. [92]

The Westinghouse Anacom was an AC-energized electrical analog computer system used extensively for problems in mechanical design, structural elements, lubrication oil flow, and various transient problems including those due to lightning surges in electric power transmission systems. The excitation frequency of the computer could be varied.
The term supermini computer or simply supermini was used to distinguish more powerful minicomputers that approached mainframes in capability. Superminis (such as the DEC VAX or Data General Eclipse MV/8000 ) were usually 32-bit at a time when most minicomputers (such as the PDP-11 or Data General Eclipse or IBM Series/1 ) were 16-bit .
