Document Summary
Digital computing mechanisms: digital computer, refers to a device that performs a sequence of computational steps on data items that have discrete values. More precise, inexpensive, and highly reliable: analog computer, operates on values that vary continuously over time. Electrical terminology: voltage and current: voltage, measured in volts, represents the potential energy difference. Schematic diagram: each line corresponds to a wire that connects one component to another, a solid dot indicates an electrical connection and a small, open circle at the end of a line indicates an external connection. Implementation of a nand logic gate using transistors. Example interconnection of gates: the electronic parts that implement gates are classified as transistor-transistor logic (ttl) because the output transistors in each gate are designed to connect directly to input transistors in other gates. A digital circuit for binary addition: the module for the low-order bits takes two inputs and produces two outputs: a sum bit and a carry bit.
