Differentiate wired and wireless systems
Short answer
Wired uses physical cables, offers higher security and stable data rates but no mobility; wireless uses free-space EM waves, provides mobility and easier installation but suffers from interference and lower security.
Differentiate between wired and wireless communication systems.
| Point | Wired | Wireless |
|---|---|---|
| Medium | Physical cable (copper, coaxial, fiber) | Free space (air or vacuum) as EMW |
| Mobility | Fixed, no mobility | Allows mobility of users |
| Installation | Costly and time-consuming to lay cables | Quick and cheap, good in hilly areas |
| Security | More secure, hard to tap | Less secure, signal can be intercepted |
| Interference | Little (shielded cable, fiber) | High, affected by weather and other signals |
| Data rate | High and stable | Lower and variable |
| Examples | Telephone, LAN, optical fiber, cable TV | Radio, TV, mobile phone, Wi-Fi, satellite |
