4 basic function of datalink layer?

Which protocol was PPP Created to replace?
SLIP
What are the five layers in the Internet protocol stack?
Application: FTP, SMTP, HTTP Transport : TCP, UTP Network : IP, routing protocols Link : PPP ethernet Physical : bit
Difference between serial line internet protocol and point to point protocol?
PPPis more secure than SLIP. PPP uses two authetication Protocols : 1. Password Authetication Protocol (PAP) 2. Challenge Handshake Authetication Protocol (CHAP) So if you use SLIP on network that unauthorized user can gain acces to.
What is the purpose of the Frame Check Sequence field in a Data Link frame trailer?
The purpose of the FCS field is to transmit the extra checksum characters added to a frame in "xyz" protocol for error detection. The most popular algorithm I've used is the CRC (cyclic redundancy check) employed in things like ethernet or PPP on a routed network. Keep in mind that ethernet defines that the errored frame should be discarded, but ethernet takes no action to cause the frame to be retransmitted. Typically most tech's see it as unnecessary overhead and opt to rely on CSMA\CD or CSMA\CA if the route is not deemed to carry time sensitive data. Hope that clears things up a bit.
What does PPP use to encapsulate multiple network-layer protocols?

What is PPP in Linux?
PPP is point to point protocol. It does single channel network links, usually over a long distance, or a VPN. The program that sets up and manages PPP connections is pppd.
What function does NCP perform in the establishment of a PPP session?
It negotiates and sets up control options on the WAN data link.
Line protocol in down then what you do?
there may be the issue with the layer 2 protocol like hdlc or ppp is not configured or wrongly configured if the interface is serial interface.
What is PPP protocol?
Point-to-Point Protocol
Which functions are provided by lcp and ncp as part of the ppp layered architecture?
LCP sets up the PPP connection and its parameters. NCP handles higher layer protocol configurations.
What enables you to connect a PC via modem to an ip network?
You need to use a protocol that will translate serial protocol (your modem) to a packet based network. Protocols such as SLIP, PPP, PPTP are used for that purpose.
What steps does PPP go through when the other end of serial link is configured with PPP encapsulation?
- When both ends of a serial WAN link are configured to run the PPP encapsulation method they establish a session based on the 3 steps below:Step 1- Link establishment and configuration negotiation- In this phase LCP opens the connection between the two interfaces and negotiates configuration options. this phase is done once the receiving router sends a configuration-acknowledgment frame back to the router who first initiates the connection...Step 2- Link quality determination (optional)- In this phase LCP tests the link between the routers to determine if the quality is sufficient to bring up the network layer protocol.Step3- Network Layer Protocol configuration negotiation- After step 2 ends, the appropriate NCP can separately configure the network layer protocols, and bring the protocol up and down at any given time. If LCP closes the link between the routers it will inform the network layer protocol so that it can take action in regards to the interfaces.- TERMS -PPP = Point-to-Point ProtocolLCP = Link Control ProtocolNCP = Network Control Protocols- hope this helps :)- miirii
What does PPP stand for?
PPP stands for point to point protocol. It's usually used in connection to modems; it allows the computer to hook up a network without being connected.
Which protocol was PPP Created to replace?
SLIP
What is the PPPOE protocol about?
The Point-to-Point Protocol over Ethernet or the PPPOE is a network protocol for encapsulating PPP frames inside Ethernet frames. The PPPOE term is something used confusingly to refer to either a modem to router protocol and/or the DSL side of things.
