Document Summary

Jacquard: weaver"s loom (power loom with automatic card reader) Charles babbage: computer difference engine, analytical engine (machine with a memory and calculating unit that could be programmed) Alan turing: general purpose computer (could compute any problem presented in a set of instructions. Konrad zuse: all-mechanical relay machine (first fully-functioning program-controlled machine) John mauchly + presper eckert: all-electronic computer, eniac (first electronic program-controlled computer, had no memory to store programs) Manchester university: manchester baby (prototype of stored programs computer) Special purpose / embedded systems: cash registers, microwaves, calculators, refrigerators. Levels of abstraction: natural language algorithm program machine architecture (isa) instruction set architecture microarchitecture logic circuits devices/transistors. The problem we want to solve (ex: find a target in a sorted array) Algorithm step-by-step procedure guaranteed to terminate, such that each step is precisely stated and can be carried out by the computer (ex: binary search) Os: operating system computer management program/interface between application programs and machine architecture.
