Which term refers to reducing the file size for transmission?

• A. Crop
• B. Compression
• C. Check Accessibility
• D. Excel Table

Answer: (B)

Compression is the process of reducing a file’s size for transmission by encoding data more efficiently. It can be lossless, which preserves every bit of information, or lossy, which removes some data to achieve greater size savings. This makes sending files faster and uses less bandwidth. For example, ZIP compresses generic files without changing their content, while JPEG reduces image detail to save space. Cropping cuts away parts of content, changing what’s shown rather than how data is stored; check accessibility focuses on making content usable for people with disabilities, not on file size; an Excel table is a way to organize data in a spreadsheet, not a method for shrinking file size.
