Document Summary

Organize in logical units: input, output, cpu(alu n cu, storage, ram. - software: any program that runs on the computer. Programming language: instructions / statements and rules to control the hardware. High level programming language: sentences are very similar to human language (i. e. c/c++, java, etc) Low level programming language: code is very similar to machine language (0"s and 1"s), assembly. Compilers translate the high level statements into machine language(object code) - computer understands 0"s and 1"s only (bit: binary digit) - i. e. base 10(decimal): 0,1,2,3,4,5,6,7,8,9 --> 10 different symbols. - base 2 (binary): 0,1 --> two different symbols. - the maximum number of numbers in base b, with d symbols is b^d. - base 10, 2 digits, xy, numbers from 0 to 99 --> 100 numbers --> 10^2. - base 10, 3 digits, xyz, numbers from 0 to 999 --> 1000 numbers --> 10^3.
