| Question 1 |
The X.25 standard specifies a
| Technique for start-stop data | |
| Technique for dial access | |
| DTE/DCE interface | |
| Data bit rate |
Question 1 Explanation:
→ The X.25 specification defines only the interface between a subscriber (DTE) and an X.25 network (DCE). X.75, a protocol very similar to X.25, defines the interface between two X.25 networks to allow connections to traverse two or more networks.
→ X.25 does not specify how the network operates internally – many X.25 network implementations used something very similar to X.25 or X.75 internally
→ X.25 does not specify how the network operates internally – many X.25 network implementations used something very similar to X.25 or X.75 internally
