Circuit Switching vs Packet Switching
| Aspect | Circuit Switching | Packet Switching |
|---|---|---|
| Connection | Dedicated path established for entire communication | No dedicated path - packets use any available route |
| Route | Same route for entire duration | Each packet can take different route |
| Resource Usage | Inefficient - line reserved even when idle | Efficient - multiple transmissions share links |
| Setup | Connection setup needed before transmission | No setup - send packets immediately |
| Reliability | If connection fails, everything stops | Resilient - packets reroute around failures |
| Order | Data arrives in order | Packets may arrive out of order (need reassembly) |
| Latency | Consistent (predictable delay) | Variable (different routes = different delays) |
| Use Case | Traditional telephone calls | Internet, email, web browsing |
| Example | Landline phone call | Internet data transmission |
