Society, Law and Ethics in one look
technology reaches further than the law that is supposed to govern it, most of the time
E-waste: what it is and why it matters
- e-waste is any discarded electronic device: old phones, batteries, circuit panels, monitors, all of it
- it often contains toxic material like lead and mercury, which leaches into soil and water if it is simply dumped
- it also contains recoverable material like copper and gold, which is exactly why proper recycling is worth doing
- throwing e-waste in with regular household waste is illegal in most places precisely because of that toxic content
Managing e-waste responsibly
- reduce: buy only what is actually needed, and keep a device working longer instead of replacing it early
- reuse: pass a working device on to someone else instead of discarding it
- recycle: send a broken device to an authorised recycler, who extracts the reusable material safely
- an authorised collection centre is the right place for anything electronic that no longer works
Gender and disability issues in technology
- the digital divide is not just about access to a device, it is also about who gets encouraged to use technology confidently
- women remain underrepresented in many technology fields, a gap that starts early and needs deliberate effort to close
- accessible design, like screen readers, captions and voice input, lets people with disabilities use technology that would otherwise shut them out
- designing for accessibility from the start almost always ends up helping everyone, not only the people it was built for
Health issues from technology use
- digital eye strain: dry, tired or blurry eyes after long screen time, eased by the twenty-twenty-twenty rule, every twenty minutes look at something twenty feet away for twenty seconds
- poor posture at a screen leads to neck and back pain over time, an ergonomic chair and screen height help prevent it
- repetitive strain from typing or a mouse can injure the wrist, regular breaks and proper hand position reduce the risk
- excessive screen time before sleep disturbs the sleep cycle, since the light itself signals the brain to stay alert

How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Computer Science chapter by chapter against your real exam dates and free hours, and when the plan reaches Society, Law and Ethics the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
