Digital Information
A way of representing information using only two options.
What is binary?
A machine that can run a program, including computers, tablets, servers, routers, and smart sensors.
What is a computing device?
Presentation of a computing innovation that that allows a user to interact with a piece of software; inputs and outputs. May be graphical or text-based.
What is the user interface?
An abstraction inside a program that can hold a value with associated data storage.
What is a variable?
A process for reducing the number of bits needed to represent something without losing any information.
What is lossless compression?
A way of representing information using ten options.
What is decimal?
A group of interconnected computing devices capable of sending or receiving data.
What is a computing network?
Data that are sent to a computer for processing by a program. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.
What is input?
Can consist of a value, a variable, an operator, or a procedure call that returns a value. This code statement is evaluated to produce a single value.
What is an expression?
Data that changes discretely through a finite set of possible values.
What is digital data?
The single unit of information in a computer
What is a bit?
The series of connections between computing devices on a network starting with a sender and ending with a receiver.
What is a path?
Data that are sent from a program to a device.
What is output?
Part of most programming languages, these include symbols or keywords for addition, subtraction, multiplication, division, and modulus operations.
What are arithmetic operators?
A search algorithm that starts at the middle of a sorted set of numbers and removes half of the data with each iteration.
What is binary search?
Error from attempting to represent a number that is too large for the space available in memory.
What is an overflow error?
An agreed-upon set of rules that specify the behavior of some system.
What is a protocol?
The application of each step of an algorithm in the order in which the code statements are given.
What is sequencing?
Joining together two or more strings end-to-end to make a new string.
What is string concatenation?
The arithmetic operator in AP Pseudocode used to return the remainder of a division problem.
What is MOD?
Data with values that change continuously, or smoothly, over time.
What is analog data?
A chunk of data sent over a network. Larger messages are divided into these that may arrive at the destination in order, out-of-order, or not at all.
What is a packet?
Form of program documentation written into the program to be read by people and which do not affect how a program runs.
What are comments?
The symbol = represents this type of operation in AP Pseudocode.
What is comparison?
A value that is either true or false.
What is a Boolean value?
A process for creating a digital representation of analog data by measuring the analog data at regular intervals.
What is sampling?
Characteristic of a network that can continue to function even in the event of individual component failures.
What is fault tolerance?
Process of using defined inputs to ensure that an algorithm or program is producing the expected outcomes.
What is testing?
A named group of programming instructions. Also referred to as a procedure.
What is a function?
An ordered sequence of characters.
What is a string?
A work or invention that is the result of creativity, such as a piece of writing or a design, to which one has rights and for which one may apply for a patent, copyright, trademark, etc.
What is intellectual property?
The protocol used for transmitting web pages over the Internet
What is HTTP (or Hyper Text Transfer Protocol)?
What is a logic error?
The symbol <- represents this type of operation in AP Pseudocode.
What is assignment?
The system responsible for translating domain names into IP addresses.
What is the Domain Name System (DNS)?
A collection of public copyright licenses that enable the free distribution of an otherwise copyrighted work, used when an author wants to give people the right to share, use, and build upon a work that they have created.
What are Creative Commons?
Differing access to computing devices and the Internet, based on socioeconomic, geographic, or demographic characteristics.
What is the digital divide?
An ordered sequence of elements. For example, [value1, value2, value3, ...]
What is a list?
Specifications for how the procedures in a library behave and can be used.
What are application program interfaces (APIs)?
An approach to a problem that produces a solution that is not guaranteed to be optimal but may be used when techniques that are guaranteed to always find an optimal solution are impractical.
What is a heuristic?
