Choose and Manage Digital Files

Create a 6–8 slide presentation for a 15-minute teacher-led consolidation in 11th-grade computer science. Slides should cover: purpose-dependent format choice; editable DOCX/ODT versus fixed-layout PDF; typical uses of PNG, JPEG, MP3, MP4, and HTML; pixel dimensions and pixels per inch for print resolution; compression and file size; PNG lossless/transparency versus JPEG commonly lossy photo compression; and file management from source to working version to exported final to backup. Include concrete examples `eco_campaign_poster_v2.pdf` and a 300-pixels-per-inch print image. State that actual file size depends on dimensions, content, and encoding, and that changing a filename extension alone does not convert data. Include concise visuals and examples only; do not create activities or assessment content.
