File or data compression is essential for multimedia activities because it significantly reduces the size of audio, video, and image files, making them easier to store, transmit, and stream. Smaller file sizes enhance loading times and reduce bandwidth usage, which is crucial for efficient online sharing and playback. Additionally, compression helps maintain quality while optimizing performance, enabling smoother user experiences across various devices and platforms. Overall, it ensures that multimedia content is accessible and manageable in today's digital landscape.

The two types of compression in multimedia are lossless and lossy compression. Lossless compression reduces file size without sacrificing any data, allowing for exact restoration of the original content, making it ideal for text and certain image formats. Lossy compression, on the other hand, reduces file size by permanently eliminating some data, which can affect quality, but is often used for audio and video files to achieve smaller sizes suitable for streaming and storage.

Data compression techniques are used to reduce the size of files and data for efficient storage and transmission. Common methods include lossless compression, which preserves all data accurately, and lossy compression, which sacrifices some data to achieve higher compression rates. Examples of compression algorithms include ZIP for general purpose compression, JPEG for image compression, and MP3 for audio compression.
Multimedia system architecture is the designing of a system that can manipulate data. This data is in different forms such as sound, graphics and text.
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.

There are some basic principles of data compression. They include advantages, disadvantages, and the history of compression. Types of compression include BZip2 and LZMA.
Activities like expanding or stretching data, increasing file sizes, or adding redundant information are non-examples of compression. Anything that does not reduce the size of data or optimize storage capacity would also be considered a non-example.
