APCSP 2.2.2 vocab
binary - A base 2 numeral system that represents all numbers, using only the two digits 0 and 1.
bit - Short for binary digit. Bits can only store one of two values, a 1 or a 0.
byte - Eight bits, able to represent 256 distinct values (abbreviated “b”).
overflow error - An error that occurs when a computer attempts to handle a number that is outside of the defined range of values.
ASCII - A standard that computers use to represent letters, numbers, and symbols (abbreviated from American Standard Code for Information Interchange).
abstraction - A very common concept in computer science and information technology meaning that a lot of the detail of a system or a process is hidden, allowing the user to focus on the details that are important for the task at hand.
pixels - A single dot in an image. Many color monitors actually have three dots (red, blue, and green) for each pixel, but it is referred to as one pixel.
transistor - Electronic devices that use tiny electronic components to store data. They can hold electric signals and can be one of two states: ON or OFF
internet - a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.
resolution - The dimensions by which you can measure how many pixels are on a screen
Unicode/UTF-8 - A multi-byte character encoding that covers most of the world's languages and writing systems, including modern and historic scripts, as well as multiple symbol sets and emoji characters
bitmap - Uses only one bit for each pixel. The bit value is 1 for black and 0 for white. That reduces the file size tremendously
