Lossy compression
A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is reversible
Lossless compression
A process for reducing the number of bits needed to represent something without losing it any information. This process is reversible
Analog data
Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race
Digital data
Digital Data - Data that changes discretely through a finite set of possible values Sampling - A process for creating a digital representation of analog data by measuring the analog data at regular intervals
Binary
A way of representing info using only two options
Bit
- A contraction of “Binary Digit”; the single unit of information in a computer, typically represented as a 0 or 1
Byte
8 bits
Decimal
A way of representing info using ten options
A program
program is a collection of program statements that performs a specific task when run by a computer. A program is often referred to as software.
Code segment
Is a collection of program statements that is part of the program
Always know
A program needs to work for a variety of inputs and situations
The behavior of the program
how a program functions during execution and is often described by how a user interacts with it
Computing innovation
innovation includes a program as an integral part of its function
A computing innovation can be physical (e.g., self-driving car), nonphysical computing software (e.g., picture editing software), or a nonphysical computing concept (e.g., e
Effective calloboration
produces a computing innovation that reflects the diversity of talents and perspectives of those who designed it.
Consultation and communication
with users are important aspects of the development of computing innovations.
Program inputs
are data sent to a computer for processing by a program. Input can come in a variety of forms, such as tactile, audio, visual, or text.
Events can be generated when a key is pressed, a mouse is clicked, a program is started, or any other defined action occurs that affects the f low of execution. CRD-2.C.4 Inputs usually affect the output produced by a program
Event-driven programming
program statements are executed when triggered rather than through the sequential flow of control.
Input
Can come from a user or other programs
Program outputs
are any data sent from a program to a device. Program output can come in a variety of forms, such as tactile, audio, visual, or text.
Logic error
A logic error is a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.
Syntax error
A syntax error is a mistake in the program where the rules of the programming language are not followe
Run-time error
I.3 A run-time error is a mistake in the program that occurs during the execution of a program. Programming languages define their own runtime errors.
