Differbetween
The major difference between HDLC and PPP is that HDLC is the bit oriented protocol, while PPP is the character-oriented protocol. The HDLC and PPP are the crucial data link layer protocols used in WAN (wide area network) where the HDLC can also be implemented with PPP for the efficient results.

What is PPP and HDLC?
HDLC stands for High-level Data Link Control. PPP stands for Point-to-Point Protocol. ... HDLC is a bit oriented protocol. PPP is a byte oriented protocol.
What is HDLC used for?
HDLC is a group of data link (Layer 2) protocols used to transmit synchronous data packets between point-to-point nodes. Data is organized into addressable frames. This format has been used for other multipoint-to-multipoint protocols, and inspired the HDLC-like framing protocol described in RFC 1662.
How HDLC PPP and Frame Relay encapsulation is different from each other?
Unlike HDLC and PPP, Frame Relay does not require a dedicated point to point link, as it is a packet-switched technology. Therefore, it does not require dedicated leased lines which means it can be more cost-effective as a WAN technology.
Is PPP still used?
PPP (Point-to-point protocol) is a WAN protocol that is often used on point-to-point links. Nowadays it's still used for DSL with PPPoE (PPP over Ethernet) and PPPoA (PPP over ATM). ...
What are the advantages of PPP over HDLC?
Advantages of PPP (3.2.
PPP includes many features not available in HDLC: The link quality management feature, as shown in Figure 3-20, monitors the quality of the link. If too many errors are detected, PPP takes the link down. PPP supports PAP and CHAP authentication.
What is the use of PPP protocol?
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. It can provide connection authentication, transmission encryption, and data compression.
How does HDLC work?
High-level Data Link Control (HDLC) is a group of communication protocols of the data link layer for transmitting data between network points or nodes. Since it is a data link protocol, data is organized into frames. A frame is transmitted via the network to the destination that verifies its successful arrival.
Is HDLC WAN?
Like the two other WAN protocols mentioned in this article, HDLC is a Layer 2 protocol (see OSI Model for more information on Layers). HDLC is a simple protocol used to connect point to point serial devices. ... HDLC would be running over the WAN, between the two locations.
What is HDLC and SDLC?
HDLC (High-Level Data Link Control) and SDLC (Synchronous Data Link Control) are two protocols that provide point to multipoint interconnection between computers. ... Because of this, HDLC is actually a standard protocol that was used by many hardware makers while SDLC is not but is still used in some IBM hardware.
Why PPP is byte oriented protocol?
It is a byte - oriented protocol that is widely used in broadband communications having heavy loads and high speeds. ... Since it is a data link layer protocol, data is transmitted in frames.
Which feature of PPP differ it from other WAN protocols?
The differences between PPP and HDLC are:
PPP is not proprietary when used on a Cisco router. PPP has several sub-protocols that make it function. PPP is feature-rich with dial up networking features.
What do HDLC PPP frame relay and ISDN have in common?
What do HDLC, PPP, Frame Relay and ISDN have in common? They operate at the physical layer. They operate at the network layer. They operate at the data link layer.
