Overflow error - an error that occurs when a computer attempts to handle a number that is outside of the defined range of values. replacing all equivalent abbreviations, spellings, and capitalizations with the same word). Metadata - data about data (ex: the date of creation or the file size of an image).Ĭleaning data - a process that makes the data uniform without changing their meaning (e.g. a piece of hardware that displays, communicates, or sends data or information from a computer. When creating a Makey Makey controller, we are making a input device to control our programs. Examples include mice, keyboards, and microphones. Information - the collection of facts and patterns extracted from data. a piece of hardware that gives, sends, or transfers data to a computer. Lossy - data compression algorithms that can significantly reduce the number of bits stored or transmitted but only allow reconstruction of an approximation of the original data. Lossless - data compression algorithms that can usually reduce the number of bits stored or transmitted while guaranteeing complete reconstruction of the original data. Samples - measured to figure out the exact bits required to store each sample.ĭata compression - reduces the size (number of bits) of transmitted or stored data. Sampling technique - measuring values of the analog signal at regular intervals called samples. Or, if you prefer, you may also be interested in downloading and using RSSAplet, a free Java RSS reader.Binary base - uses only combinations of the digits zero and one.ĭecimal base - uses only combinations of the digits 0 – 9.Ībstraction - the process of reducing complexity by focusing on the main idea by hiding details irrelevant to the question at hand and bringing together related and useful details, it reduces complexity and allows one to focus on the idea.Īnalog data - values that change smoothly, rather than in discrete intervals, over time (ex: pitch and volume of music, colors of a painting, or the position of a sprinter during a race).
