Chapter 2 - How Computers & Programs Work Flashcards
What is a Switch (not the cool kind)
Controls whether or not electricity flows through a wire.
What do 1 and 0 represent in terms of electricity flow
1 = electricity flow 0 = no electricity flow
What is “bits” short for
‘Bi’nary Dig’its’
What is a circut
connection of multiple switches that can be used to perform calculations
What is a processor
Special circuits that execute a list of desired calculation.
What is an instruction
a single calculation for the processor
What is memory
A circuit that can store instructions by giving thousands of 1s and 0s address location.
The programmer-created sequence of instructions is called a _____ or an _____
program, app
Define machine instructions
original programs written specifically in 0s and 1s
Define executable program
sequence of 0s and 1s
Define assembly language
compiles basic human friendly text into 1s and 0s for computers to read
Define high level language1
Program that is more advanced than assembly, can support functions and algorithms
Define compilers
programs that translate high level languages into executable programs
What is a cache
RAM memory stored on the CPU itself
Define clock
,easured in hertz, instructions that are executed at specific intervals of time
