We saw earlier how analog machines worked and what were the difficulties.  With the discovery of electricity and circuits, it became possible to represent things using electric signals. Using a series of circuits and electrical signals, it became possible to perform calculations, bringing in the electromechnical analog computers.

Using a series of circuits and electrical signals, it became possible to perform calculations, bringing in the electro-mechnical analog computers.

When Alan Turing developed a theory that a computer can be programmed to solve any problem, the development of modern computers as we now know it began. The use of Boolean algebra, which helped developing logical circuits for electrical signals launched the digital revolution.  Boolean logic uses the binary system where information is represented as a series of "0"s and "1"s thus allowing information to be accessed through only a combination of "1"s and "0"s.  This allowed information to be communicated in discrete bits which could be combined and recombined. Such a computer which uses "0"s and "1"s to perform computations a digital computer.

What makes our society now different from ever before is the presence of digital technologies. This development came with the development of new methods of designing circuits like transistors and micro chips; thus giving birth to the digital computer.
