Lossless compression - Study guides, Class notes & Summaries

Overflow - Answer error that results when the number of bits is not enough to hold the number, like a car's odometer "rolling over" Round-off - Answer error that results when the number of bits is not enough to represent the actual number, like 3 digits to represent π as 3.14 Lossy - Answer Compressing data in a way that throws some data away and makes it almost impossible to recover the original, great compression, like JPEG images Lossless - Answer Compressing data in ...

Digital Revolution - is an ongoing process of social, political, and economic change brought about by digital technology, such as microchips, computers, and the Internet. Convergence - The expansion of cloud computing , a process by which several technologies with distinct functionalities evolve to form a single product. Your computer plays movies. Your cell phone has a camera. Your clock has a radio. The Web - is a collection of linked documents, graphics, and audio that can be accessed ov...

Match the following file and image types with their correct definitions. - ️️-JPG- High quality raster images with lossy compression which results in decreased image quality after each image edit. -PNG- True color, supports transparency, and is lossless, meaning an image will retain the same quality regardless of how many times it's been edited. -GIF- Can only contain up to 256 colors, supports transparency, and can be animated. -WEBP- Developed by Google in an attempt to combine the bes...

Ap computer science Question and Answer 100% Correct Which of the following is an advantage of a lossless compression algorithm over a lossy compression algorithm? A lossless compression algorithm can guarantee that compressed information is kept secure, while a lossy compression algorithm cannot. B A lossless compression algorithm can guarantee reconstruction of original data, while a lossy compression algorithm cannot. C A lossless compression algorithm typically allows for faster tr...

Digital vs. Analog digital reads a series of ones and zeros, while analog reads a continuous flow of data. Lossy Describes a method of compression in which data is lost in a way that cannot be recovered from the compressed data. Lossless Compression a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data. pixel interpolation A process that is used by graphics software to average the color of adjacent pixels in an image, usually whe...
