What is PPP protocol used for?

The Point-to-Point Protocol (PPP) is a data link protocol commonly used in establishing a direct connection between two networking nodes and has largely superseded the older Serial Line Internet Protocol (SLIP) and other standards. It can provide connection authentication, transmission encryption, and compression.

What are the advantages of the PPP protocol?

Compared with other link-layer protocols, PPP has the following advantages:

PPP supports both synchronous and asynchronous links, whereas SLIP supports only asynchronous links, and other link-layer protocols, such as X.
PPP is highly extensible.
PPP uses a Link Control Protocol (LCP) to negotiate link-layer parameters.

What is the purpose of using PPP protocol instead HDLC?

PPP is used in synchronous media as well as asynchronous media. 8. HDLC does not offer error detection. PPP provides the feature of error detection using FCS (Frame Check Sequence) while transmitting data.

What are the key features of the Point-to-Point Protocol PPP )? Choose three?

PPP has the following three main components: a way to encapsulate multiprotocol datagrams; Link Control Protocol to establish, configure and test the data link connection; and. a group of separate network control protocols that establish and configure different types of network layer protocols.

What are the two components of PPP?

Key Concept PPP has two components: LCP that is responsible establishing, configuring, maintaining, and terminating the connection, and NCP which is specific to the Layer 3 protocol encapsulated by PPP.

Is PPP protocol still used?

PPP (Point-to-point protocol) is a WAN protocol that is often used on point-to-point links. Originally, PPP was often used for dial-up connections. Nowadays it’s still used for DSL with PPPoE (PPP over Ethernet) and PPPoA (PPP over ATM).

What is the advantage of using PPP over HDLC on serial interface?

Between HDLC and PPP, the PPP protocol performs better than HDLC because there is no compulsion of using the Cisco devices in both the ends, which means these are interoperable. PPP also supports multiple protocols and support authentication.

What is the advantage of using PPP over serial over HDLC?

There are many advantages to using PPP including the fact that it is not proprietary. 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.

Which of the following protocols are used by PPP protocol?

PPP uses NCP to establish and configure different network layer protocols. PPP is designed to allow the simultaneous use of multiple network layer protocols, including IPv4 and v6, IPX, and AppleTalk. PPP operates using different network layer protocols (e.g., IPX and AppleTalk), whereas SLIP uses only TCP/IP-based IP.

What is PPP encryption?

Microsoft Point-to-Point Encryption (MPPE) encrypts data in Point-to-Point Protocol (PPP)-based dial-up connections or Point-to-Point Tunneling Protocol (PPTP) virtual private network (VPN) connections. 128-bit key (strong), 56-bit key, and 40-bit key (standard) MPPE encryption schemes are supported.

What is PPP in tourism give an example?

Opportunities for PPPs in tourism can be applied across a huge span of activities, offering both public goods, like historical artifacts, natural parks, and museums, and private goods and services, like hotels, entertainment events, and theme parks.

What is the role of NGOs in tourism activities?

These NGOs create awareness among the people regarding resources and tourism assets in relation to tourism development. They also show the right track in which the development should take place. These NGOs also help in sustaining culture, conserving environment, land etc. due to tourism development.

What protocol does PPP use to identify the network layer protocol?

Network Control Protocol (NCP)
The correct answer is NCP. Network Control Protocol (NCP) is used to help identify the Network layer protocol used in the packet.

Which statement is true for the PPP protocol?

9. Choose the correct statement from the following. Explanation: PPP allows termination of the link at any time in any phase because it works on the data link layer which is the layer in control of the link of the communication. 10.

What does PPP encryption mean?

Point-to-Point Protocol
Microsoft Point-to-Point Encryption (MPPE) encrypts data in Point-to-Point Protocol (PPP)-based dial-up connections or Point-to-Point Tunneling Protocol (PPTP) virtual private network (VPN) connections. 128-bit key (strong), 56-bit key, and 40-bit key (standard) MPPE encryption schemes are supported.

What are PPP projects in the Philippines?

In the Philippines, PPP is similarly defined as a contractual agreement between the Government and a private firm targeted towards financing, designing, implementing and operating infrastructure facilities and services that were traditionally provided by the public sector (Public-Private Partnership Center, 2015b).

What is the importance of non-governmental organizations?

At nearly every level of the different attempts to preserve the dignity of individual citizens when this is threatened by the power of the state, NGOs play a crucial role in: fighting individual violations of human rights either directly or by supporting particular ‘test cases’ through relevant courts.

Who started PPP in the Philippines?

Public-private partnerships are not new in the Philippines, having been introduced as early as 1990 under the administration of President Corazon Aquino through Republic Act No. 6957.

What is the role of non governmental organizations NGOs in the country like human rights and civil liberties or society or groups in the treaty compliance?

In particular, nongovernmental organizations (NGOs) have played a primary role in focusing the international community on human rights issues. NGOs monitor the actions of governments and pressure them to act according to human rights principles.
