ICMP (internet control message protocol)
reports on the success or failure of data delivery.
Which protocol is used to deliver data?
TCP
stands for Transmission Control Protocol a communications standard that enables application programs and computing devices to exchange messages over a network. It is designed to send packets across the internet and ensure the successful delivery of data and messages over networks.
What is the main protocol of network layer?
The foremost data link layer protocol is
the Ethernet protocol
. The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks–hence, the name internet.
Which protocol works in conjunction with IPv4 to discover the MAC address of a host or node on the local network?
A core protocol in the TCP/IP suite that belongs in the Data Link layer of the OSI model.
ARP
works in conjunction with IPv4 to discover the MAC address of a node on the local network and to maintain a database that maps local IP addresses to MAC addresses.
What is the most common type of protocol that sends data on the Internet?
HTTP
– One of the most familiar protocols, hyper text transfer protocol (HTTP) is often referred to as the protocol of the internet. HTTP is an application layer protocol that allows the browser and server to communicate.
Which network protocol is used to handle the reliable delivery of information?
TCP
is a reliable transport protocol, and performs processes to ensure reliable delivery of data between applications using acknowledged delivery.
Which of the following protocol is used for delivering data from the source of to the destination?
IP
has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered.
What is meant by network protocol?
A network protocol is
an established set of rules that determine how data is transmitted between different devices in the same network
. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.
Which of the following protocol is used to report and correct the error at network layer?
The ICMP
stands for Internet Control Message Protocol. It is a network layer protocol. It is used for error handling in the network layer, and it is primarily used on network devices such as routers.

What is protocol name any one protocol used on the Internet?
Common Internet protocols include
TCP/IP (Transmission Control Protocol/Internet Protocol)
, UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol). TCP/IP is a stream protocol.
How TCP protocol provides reliability?
Unlike UDP, TCP provides reliable message delivery. TCP ensures that data is not damaged, lost, duplicated, or delivered out of order to a receiving process. … TCP achieves this reliability by
assigning a sequence number to each octet it transmits and requiring a positive acknowledgment (ACK) from the receiving TCP
.
Why does the Internet protocol network layer not provide for reliable delivery of packets?
The IP layer provides an unreliable, connectionless delivery system. The reason why it is unreliable stem from the fact the protocol
does not provide any functionality for error recovering for datagrams
that are either duplicated, lost or arrive to the remote host in another order than they are send.
Which network protocol is used to handle the reliable delivery of information TCP UDP IP ICMP?
The two most important protocols in the Transport Layer are Transmission Control Protocol (TCP) and
User Datagram Protocol (UDP)
. TCP provides reliable data delivery service with end-to-end error detection and correction. UDP provides low-overhead, connectionless datagram delivery service.
How reliable delivery is ensured at the transport layer?
End-to-end Connection between hosts –
TCP ensures reliable delivery of messages
and is used in various applications. UDP, on the other hand, is a stateless and unreliable protocol that ensures best-effort delivery.
Which 2 protocols are used in the transport layer of the TCP IP model?
The two protocols used in the transport layer are
User Datagram protocol and Transmission control protocol
. It provides connectionless service and end-to-end delivery of transmission.
Are delivered by the transport layer in process to process delivery mechanism?
The transport transport layer is responsible responsible for process-to-
process delivery
—the delivery of a packet, part of a message, from one process to another. Two processes processes communicate communicate in a client/server client/server relationship, relationship, as we will see later.
What are the types of network protocol?
- Transmission Control Protocol (TCP)
- Internet Protocol (IP)
- User Datagram Protocol (UDP)
- Post office Protocol (POP)
- Simple mail transport Protocol (SMTP)
- File Transfer Protocol (FTP)
- Hyper Text Transfer Protocol (HTTP)
- Hyper Text Transfer Protocol Secure (HTTPS)
What are the data link layer protocols?
Examples of data link protocols are
Ethernet, Point-to-Point Protocol (PPP), HDLC and ADCCP
. In the Internet Protocol Suite (TCP/IP), the data link layer functionality is contained within the link layer, the lowest layer of the descriptive model, which is assumed to be independent of physical infrastructure.
What are the three major network protocols?
Major types of network protocols
Generally speaking, there are three types of protocols in networking — communication, such as
Ethernet
; management, such as Simple Mail Transfer Protocol (SMTP); and security, such as Secure Shell, or SSH.
Is TCP a network layer protocol?
In terms of the OSI model, TCP is
a transport-layer protocol
. It provides a reliable virtual-circuit connection between applications; that is, a connection is established before data transmission begins. … Internet Protocol (IP) In terms of the OSI model, IP is a network-layer protocol.
What is network layer example?
While TCP/IP is the newer model, the Open Systems Interconnection (OSI) model is still referenced a lot to describe network layers. … Network (e.g.
IP, routers
) Transport (e.g. TCP, UDP, port numbers) Session (e.g. Syn/Ack)
What are the 5 network layers?
The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the
physical, data link, net- work, transport, and application layers
. Not all layers are completely defined by the model, so these layers are “filled in” by external standards and protocols.
What is Layer 2 networking?
Layer 2 is equivalent to the link layer (the lowest layer) in the TCP/IP network model. Layer2 is the network layer
used to transfer data between adjacent network nodes in a wide area network
or between nodes on the same local area network.
Is ICMP a network layer protocol?
ICMP is
a network-layer protocol
. There is no TCP or UDP port number associated with ICMP packets as these numbers are associated with the transport layer above.
What is the difference between network layer delivery and transport layer delivery?
Network Layer Transport Layer | The main function of this layer is to deliver packets from source to destination across multiple networks. Transport layer is responsible for source to destination delivery of the entire message. |

What is meant by MAC protocol?
Media access control
(MAC) protocols enforce a methodology to allow multiple devices access to a shared media network. Before LANs, communication between computing devices had been point-to-point. That is, two devices were connected by a dedicated channel.
What layer is the data link layer?
The data link layer (
Layer 2
) of the OSI model actually consists of two sublayers: the Media Access Control (MAC) sublayer and the Logical Link Control (LLC) sublayer. The MAC sublayer controls device interaction.
In which layer of MAC address is appended to data?
This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the
medium access control protocol sublayer of the data link layer
.
How are MAC addresses used in networks?
A MAC address is a
unique serial number assigned to each network interface controller (NIC)
. This allows a network to uniquely identify any device, even when a dynamic IP address is assigned using DHCP, each time the device connects to a network.
The MAC layer is one of the two sublayers that make up the data link layer. The main job of the MAC layer is
to move the data from the network interface card of a network to a shared channel
. The MAC layer along with data link control is responsible for the complete physical addressing of the data link layer.
Why are network protocol layers important?
Layers
provide a division of the work done by a network
. Networks are set up with a protocol hierarchy that divides the communication task into several layers. A protocol is a set of rules for communication within a layer. A service is what the layer provides to the layer above it through an interface.
Why is network layer important?
It
determines the route from the source to the destination
and also manages the traffic problems such as switching, routing and controls the congestion of data packets. The main role of the network layer is to move the packets from sending host to the receiving host.
What are the main responsibilities of network layer?
Main responsibility of Network layer is
to carry the data packets from the source to the destination without changing or using it
. If the packets are too large for delivery, they are fragmented i.e., broken down into smaller packets.
