Point-to-Point Protocol (PPP) refers to a suite of computer communication protocols that provide a standard way to transport multiprotocol data over point-to-point links.
What is PPP protocol used for?
What is a PPP frame?
Why PPP is byte oriented protocol?
What are the three components of PPP?
What is a TCP IP model?
TCP/IP Reference Model is a four-layered suite of communication protocols. It was developed by the DoD (Department of Defence) in the 1960s. It is named after the two main protocols that are used in the model, namely, TCP and IP. TCP stands for Transmission Control Protocol and IP stands for Internet Protocol.
What is a node for Internet?
A network node can be defined as the connection point among network devices such as routers, printers, or switches that can receive and send data from one endpoint to the other.
What is HDLC in data communication?
HDLC (High-level Data Link Control) is a group of protocols or rules for transmitting data between network points (sometimes called nodes). In more technical terms, HDLC is a bit-oriented, synchronous data link layer protocol created by the International Organization for Standardization (ISO).
Is PPP still used?
Notice: The Paycheck Protection Program (PPP) ended on May 31, 2021. Existing borrowers may be eligible for PPP loan forgiveness. SBA also offers additional COVID-19 relief.
What is the data link layer?
The data link layer is the protocol layer in a program that handles the moving of data into and out of a physical link in a network. The data link layer is Layer 2 in the Open Systems Interconnection (OSI) architecture model for a set of telecommunication protocols.
What are the benefits of IPv6?
- No more NAT (Network Address Translation)
- Auto-configuration.
- No more private address collisions.
- Better multicast routing.
- Simpler header format.
- Simplified, more efficient routing.
- True quality of service (QoS), also called “flow labeling”
- Built-in authentication and privacy support.

What’s a node in C?
A “node” is a concept from graph theory. A graph consists of nodes (vertices) and edges that connect the nodes. A node in C can be represented as a structure (a struct ) that has all the necessary data elements “on board” to implement a graph. Optionally a structure may be required that represents the edges.
What is computer network switch?
A network switch connects devices (such as computers, printers, wireless access points) in a network to each other, and allows them to ‘talk’ by exchanging data packets. Switches can be hardware devices that manage physical networks, as well as software-based virtual devices.
What is piggybacking in data link layer?
The receiver waits until its network layer passes in the next data packet. The delayed acknowledgment is then attached to this outgoing data frame. This technique of temporarily delaying the acknowledgment so that it can be hooked with next outgoing data frame is known as piggybacking.
What is Frame Relay used for?
Frame relay is commonly used to connect two or more LAN bridges over large distances. The iSeries system supports these frame-relay network connections: Frame relay direct network: Allows data that uses SNA or TCP/IP communications over a frame-relay network to move at speeds of up to 2.048 Mbps.
What is the PPP password?
The Password Authentication Protocol (PAP) provides a simple method for the peer to establish its identity using a two-way handshake. After the link is established, an ID and password pair is repeatedly sent by the peer to the authenticator until authentication is acknowledged or the connection is terminated.
How do I pay back a PPP loan?
The website you can use to repay your EIDL loan can be found at Pay.gov. You must have your 10-digit loan number and a payment amount in order to pay it back. There is no prepayment penalty but it is possible a minimal amount of interest has accrued from the time the loan was disbursed.
What is media access control MAC?
What Does Media Access Control (MAC) Mean? Media access control (MAC) is a sublayer of the data link layer (DLL) in the seven-layer OSI network reference model. MAC is responsible for the transmission of data packets to and from the network-interface card, and to and from another remotely shared channel.
What is Hub in computer network?
A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A hub is less sophisticated than a switch, the latter of which can isolate data transmissions to specific devices. Network hubs are best suited for small, simple local area network (LAN) environments.
Why is there no IPv5?
The reason is that IPv5 doesn’t exist. It never made it to become one of the IP protocols. It was planned as a streaming protocol, and it got to its second version, ST2. Its packets had the IP version 5 ID but eventually died as a draft.
How do you make a linked list in Python?
Creation of Linked list. A linked list is created by using the node class we studied in the last chapter. We create a Node object and create another class to use this ode object. We pass the appropriate values through the node object to point the to the next data elements.
