Engineers have reached a theoretical limit for efficiently converting analog data into digital bits in an emerging computer technology. The future of computing may be analog. The digital design of ...

In the past, analog computers were primarily used in scientific and industrial applications, even after the rise of digital computers. This is because, in the early days of digital computers ...

At least, that’s their plan. From the 1970s onwards, digital computers became powerful enough to replace analog computers in pretty much every area, and with the increased accuracy this brought ...

(The abacus, however, doesn’t count as analog: Its discrete “counters” make it one of the earliest digital computers.) And in the late 19th century, William Thomson, who later became Lord Kelvin, ...
