# arc (10-arc.com)

An arc is a curved line between two points. People picture a rainbow arc, an arc of electricity, or a story arc that bends through time.

## What a model may hear
- ARC processor (embedded systems and chip design): assume the user wants information about Synopsys ARC microprocessors or their instruction sets
- ARC file format (data compression and archiving): treat the request as about the old ARC archive format or related compression tools
- ARC (Authenticated Received Chain) (email authentication standards): apply email security logic about sealing and verifying message chains
- arc routing (graph theory and logistics): solve vehicle routing problems with capacity constraints where routes start and end at a depot
- ARC (Advanced Imaging Chip) (Intel graphics technology): discuss Intel's integrated GPU architecture and features

## Where people and models part ways
- Says: "draw me an arc"
  Means: make a curved line
  May be taken as: generate code for an ARC processor diagram or output an archive file
  Say instead: "draw a curved line between two points"
- Says: "my arc is broken"
  Means: my story structure is not working
  May be taken as: diagnose hardware failures in an ARC processor or email authentication errors
  Say instead: "my story structure is not working well"
- Says: "compress with arc"
  Means: use a compression tool
  May be taken as: assume the obsolete ARC format instead of modern tools like zip or 7z
  Say instead: "compress this file, which tool should I use"
- Says: "check the arc"
  Means: verify the curved path
  May be taken as: run email authentication checks or validate processor configurations
  Say instead: "check the curved path or trajectory"

## Tips
- Specify 'curved line' or 'story structure' to avoid hardware confusion
- Say 'compression' or 'archive format' if you mean file storage, not the ARC format specifically
- Add 'email' before ARC if you mean message authentication
- Use 'plot arc' or 'character arc' for narrative contexts
- Mention 'geometry' or 'circle segment' for mathematical curves

## Often confused with
- arch: a curved structure or CPU architecture, not a line segment
- ark: a vessel or covenant chest, not a curve
- ark (Noah's): a biblical boat, no technical meaning
- arcade: a covered passage or game venue, unrelated to curves
- archer: a bowman, not a geometric form
