让我们看看 SLIP 和 PPP 之间的区别：
| S.NO | SLIP | PPP |
|---|---|---|
| 1. | SLIP stands for Serial Line Internet Protocol. | PPP stands for Point-to-Point Protocol. |
| 2. | SLIP is a Predecessor protocol of PPP. | While It is a Successor protocol of SLIP. |
| 3. | SLIP covers the internet protocol packet. | While it covers the datagram. |
| 4. | SLIP does not provide authentication. | While PPP provides authentication. |
| 5. | The derived Protocol from SLIP is Compressed SLIP. | While the derived protocol from PPP is PPP over Ethernet and PPP over ATM. |
| 6. | SLIP is a static IP addressing assignment. | While it is a dynamic IP addressing assignment. |
| 7. | In SLIP data is transferred in synchronous form. | While in this, data is transferred in both synchronous and asynchronous form. |
