CSP

overflow error

data too large to represent

roundoff error

data too specific to represent

bits can be used to represent

color, sound, words

heuristic

no perfect solution, so approximate solution decent

argument

value given to parameters

parameter

variables in function

return

value of expression after function

abstraction

allows procedure to be used knowing what it does, not how it does it, allowing solution to be based on smaller subsolutions (functions0

number of binary searches for list of n variables

log base2 n

packets

chunk of data sent over network (pieces of larger messages - can be sent in order or out of order or not)

digital certificates

verifies identity

phishing

tricks user into providing information

rogue access point

gives unauthorized access to networks

malware

virus installed that controls computer

symettric encryption

one key for both

public key

anyone can encrypt it but the reciever needs a private key to decrypt it

when is binary search possible

can have repeat elements but must be sorted in numerical/alphabet order

sequencing

putting steps in an order

selection

deciding which steps to do next

iteration

repeating some steps

procedure

function

assignment operator

allows a program to change the value represented by a variable

documentation

description of how a peice of code works (ie. comment)

DOmain name system

translates domain names into IP addresses

HTTP

transmits web pages

bandwidth

max data that can be sent in x amount of time

analog data

has values that change continuously (position of person during race, music, colors)

byte

8 bits

tcp

reliable but slower

udp

faster but less reliable
