The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...
The first stored-program transistor computer was the ETL Mark III, developed by Japan's Electrotechnical Laboratory [50] [51] [52] from 1954 [53] to 1956. [51] However, early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, which limited them to a number of specialized ...
The category of early computers contains the computer systems made in the early era (i.e., the era in modern computer history defined as the period from the late 1930s to the early 1960s) utilizing mechanical, vacuum tube, discrete transistor, or other pre-integrated circuit technology.

One major improvement over Charles Babbage's non-functional device is the use of Leibniz's binary system (Babbage and others unsuccessfully tried to build decimal programmable computers). Zuse's machine also featured floating-point numbers with a 7-bit exponent, 14-bit mantissa (with a '1' bit automatically prefixed unless the number is 0), and ...
The first computer to ship with the Intel 8080 microprocessor in April 1974 (as a pre-production unit) and one of the first commercially available computers with the 8080 in June 1974 (first production units shipped August 1974). Also included a built-in printer and early flat-panel plasma display. [16] [21] Sord Computer Corporation SMP80/08 ...
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
The first computer in Denmark; had an early implementation of ALGOL: UNIVAC 1104: 1957 A 30-bit variation of the UNIVAC 1103 Ferranti Mercury: 1957 19: An early commercial vacuum tube computer by Ferranti, with core memory and hardware floating point capability IBM 610: 1957 180: A small computer designed to be used by one person with limited ...
The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] The device was limited by the technology of the day. The ABC's priority is debated among historians of computer technology, because it was neither programmable , nor Turing-complete . [ 2 ]
