- Widely supported across many operating systems and devices
- Useful for troubleshooting legacy systems
Cons
- Lacks security features like encryption, making it susceptible to interception
- Superseded by more secure protocols such as SSH
- Potentially dangerous if used over untrusted networks without safeguards
- Not suitable for modern secure communications
