2
logic error
a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.
New cards
3
run-time error
A mistake in a program that happens only when the program is actually run, such as a program attempting to access memory that does not exist.

A continuous representation of data
New cards
9
lossless compression
a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data.
New cards
10
lossy compression
data compression techniques in which some amount of data is lost. This technique attempts to eliminate redundant information.

13
Selection
the process of choosing which sensory information to focus on

14
Iteration
repetition
New cards
15
linear serach
checking each element of a list until the desired value is found or the whole list is checked
New cards
16
Binary Search
a search algorithm that starts at the middle of a sorted set of numbers and removes half of the data; this process repeats until the desired value is found or all elements have been eliminated.
New cards
17
reasonable time
polynomial in the number of steps an algorithm takes in the worst case based on the input size
New cards
18
heuristic
a simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms

New cards
24
Bandwidth
The maximum amount of data that can pass from one point to another in a unit of time
New cards
25
protocol
A set of rules governing the exchange or transmission of data between devices.

27
IP
(Internet Protocol) Routing protocol that is in charge of forwarding packets on the Internet.
New cards
28
TCP
(Transmission Control Protocol) provides reliable, ordered, and error-checked delivery of a stream of packets on the internet. TCP is tightly linked with IP and usually seen as TCP/IP in writing.
New cards
29
UDP
User Datagram Protocol. Used instead of TCP when guaranteed delivery of each packet is not necessary. UDP uses a best-effort delivery mechanism.
New cards
30
World Wide Web
a system of linked pages, programs, and files
New cards
31
HTTP
HyperText Transfer Protocol - the protocol used for transmitting web pages over the Internet
New cards
32
Parallel Computing
a model in which programs are broken into small pieces, some of which are run simultaneously
New cards
33
speedup
the time used to complete a task sequentially divided by the time to complete a task in parallel
New cards
34
distributed computing
processes and manages algorithms across many machines in a computing environment
New cards
35
digital divide
A worldwide gap giving advantage to those with access to technology
New cards
36
crowdsourcing
using consumers to develop and market products
New cards
37
citizen science
scientific research by amateur scientists

MFA
Multi-factor authentication (MFA) is a security control that requires users to verify their identities by providing multiple pieces of evidence before gaining access to a device or application.
New cards
42
Encryption
a process of encoding messages to keep them secret, so only "authorized" parties can read it.
New cards
43
Symmetic Encryption
the same key is used to encode and decode
New cards
44
Public Key Encryption
uses two keys: a public key that everyone can have and a private key for only the recipient
