What is the general term used to describe a piece of data at any layer of a networking model?
Packet
The Application layer separates data into or discrete amounts of data?
PDU (protocol data units) -Yuriy-
Why is data protocol used?
data protocol is used to route the data from the source to destination, and it is also used for congestion control, flow control & error control in the data that is being transmitted........... data protocol is responsible for the end to end delivery of the data, which may be in the form of messages, frames, packets across the different layers of the protocol architecture....
Is TCP a reliable protocol for data transmission?
Yes, TCP (Transmission Control Protocol) is a reliable protocol for data transmission. It ensures that data is delivered accurately and in the correct order by using error checking and retransmission of lost packets.
What is peer to peer process in osi model?
Protocol layers may be defined in such a way that the communications within a layer is independent of the operation of the layer being being used. This is known as "peer-to-peer" communication and is an important goal of the OSI Reference Model. Each layer provides a protocol to communicate with its peer. When a packet is transmitted by a layer, a header consisting of Protocol Control Information (PCI) is added to the data to be sent. In OSI terminology, the packet data (also known as the Payload) is called a Protocol Data Unit (PDU). The packet so-formed, called a Service Data Unit (SDU) is passed via a service access point to the layer below. This is sent using the service of the next lower protocol layer.
What is pdu encapsulation?
protocol data unit
Term used for a data packet often implying a specific layer or protocol?
Protocol Data Unit (PDU)
What Protocol Data Unit is employed at the Transport Layer?
PACKETS
What is the Protocol data unit at the network layer?
frame
What is an application protocol data unit?
In the context of smart cards, an application protocol data unit is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4 Organization, security and commands for interchange.
What two ways can a unit of data be sent across a network?
1 tcp transmission control protocol 2 udp protocol
What is the general term used to describe a piece of data at any layer of a networking model?
Packet
What is stop and wait protocol?
Stop and wait protocol is used in telecommunications as a method to send information between two connected devices. It sends information in a Protocol Data Unit and waits for a response.
What is the mechanism used by bridges running STP to exchange information?
Bridge protocol data unit BPDU
Explain about protocol data unitidentify PDU in each layer of OSI?
A Protocol Data Unit (PDU) is a unit of data specified in a protocol of a given layer of the OSI model. Each layer has its own PDU: at the Application layer, it's called a message; at the Transport layer, it's a segment (or datagram in UDP); at the Network layer, it's a packet; at the Data Link layer, it's a frame; and at the Physical layer, it's a bit or symbol. These PDUs help in managing and encapsulating data as it traverses through the layers of the OSI model.
The Application layer separates data into or discrete amounts of data?
PDU (protocol data units) -Yuriy-
The PDU at the Transport layer is called?
The PDU (protocol data unit) @ transport layer (e.g. TCP or UDP) is called as 'segment' .
