Switching circuit theory is the mathematical study of the properties of networks of idealized switches. Such networks may be strictly combinational logic, in which their output state is only a function of the present state of their inputs; or may also contain sequential elements, where the present state depends on the present state and past states; in that sense, sequential circuits are said ...

The switch circuit creates a continuous metallic path for current to flow (in either direction) between its input and its output. The semiconductor logic gate, on the other hand, acts as a high- gain voltage amplifier , which sinks a tiny current at its input and produces a low-impedance voltage at its output.
Donald Davies' work on data communications and computer network design became well known in the United States, Europe and Japan and was the "cornerstone" that inspired numerous packet switching networks in the decade following.
The disadvantage of this type of switch is that it introduces a delay into the signals. When a packet (or byte, on telephone switches) comes to the input, the switch stores the data in RAM in one sequence, and reads it out in a different sequence. Switch designs vary, but typically, a repeating counter is incremented with an internal clock. It ...
EDSAC, on which the book was based, was the first computer in the world to provide a practical computing service for researchers. [2] Demand for the book was so limited initially that it took six years to sell out the first edition. [7] As computers became more common in the 1950s, the book became the standard textbook on programming for a time ...
The IBM 701 computer (1952–1956) had a "Load" button that initiated reading of the first 36-bit word into main memory from a punched card in a card reader, a magnetic tape in a tape drive, or a magnetic drum unit, depending on the position of the Load Selector switch. The left 18-bit half-word was then executed as an instruction, which ...
