Answer / pavan kumar
HDLC and PPP are the protocols used in Leased lines and
also in ISDN.HDLC-High Level Data Control,PPP-Point To
Point Protocol.
mainly HDLC is cisco proprietary protocol and PPP is OSI
protocol.PPP checks for authorization.It inter=grates with
2 protocols PAP and CHAP.
PPP supports compression and HDLC doesnt support
compression.

Answer / shafi sache
HDLC(High-level Data Link Protocal)
1)HDlC is Data Link Layer Protocl and it is a Communication
Protocal .
2)HDLC is Cisco prperitry prtocal and Devloped by ISO and
it is delovped out of IBM'S SDLC(Synchronous Data Link
Protocol)
3)HDLC is superset of SDLC.
4)It supports only Synchronous comunication.
5)It has 3 transfer modes of Normal Response mode
(NRM),Asynchronous Response Mode(ARM),Asynchronous
Balanced Mode(ABM).
PPP(Point To Point Protocol)
1)It is used for direct Comunication between 2 nodes,it has
no transfer mode like HDLC.
2)PPP is type of HLDC .
3)It supportd encryption,authentication and Comparision.
4)Authenticaion Support by PAP (password authenticaion
protocol) and also by CHAP(Challange Handshake Protocal).
5)It is not a Cisco Proprietary.

Answer / arslan asif
1)-PPP(point to point network protocol)support user
authentication.e.g,PTCL asked user name & Password from
his/her client.
2)-HDLC(High level data link protocol)does't support user
authentication.It is used in Wan Connections.

Answer / abhi
Differences between HDLC and PPP are
(1) HDLC is cisco proprietary while PPP is an open standard.
(2) HDLC does not provide authentication while PPP provides authentication like PAP and CHAP.
(3) HDLC does not support compression while PPP support compression.
(4) HDLC supports synchronous networks only while PPP supports both synchronous and asynchronous networks.
