Which layer manages the end to end control and error checking?
layer 4
What happens to the transport layer PDU as the packet moves through the network?
manages the data transport between the processes running on each end host
Which layer of the OSI model is concerned with end-to-end message delivery over the network?
transport layer of osi model is responsible for end to end delivery of packets over a network
Difference between transport and network layer?
+network layer logical communication between hosts +transport layer: logical communication between processes ex: we have 2 house and one house have 12 room. kids in the houses send letter together. network layer: only send letter between the houses transport layer: it make sure that the letter be sent to right the room in the house.
What are three basic operations of reliability in the transport layer?
tracking transmitted dataacknowledging received dataRetransmitting acknowledge data
Which layer of the OSI model encapsulates Network layer pockets?
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
What OSI model guarantees reliable message delivery?
The Transport layer which handles segments is responsible for End-to-End connections and reliability. Problems at this layer can negatively impact reliable message delivery. Although the Transport layer is supposed to be where reliability is provided, problems at the Network layer where packets are handled can also significantly affect reliable message delivery if the path determination and/or IP (logical addressing) are messed up.
What manages data transmission between the front end and the database server?
CGI (Common Gateway Interface) Script
How does TCP and IP address works on networking?
TCP/IP is composed of layers, wherein each layer is responsible for performing certain operations on the data it receives and passing it to the higher layers. Each layer deals with certain issues related to the transmission of data and renders certain services to its higher layers. The TCP/IP model consists of the link layer, the Internet layer, the transport layer and the application layer. Each layer consists of a set of protocols that function on the level of that layer. The link layer protocols are responsible for connecting the nodes in a network. The Internet layer consists of protocols, specifications and methods that are used to transport data packets across the network. The transport layer protocols deal with the transmission of data packets between source and destination network hosts. The application layer, the topmost layer in TCP/IP, directly interacts with application services. Thus, we see that TCP/IP functions at all the levels of communication between the components of a network. It is truly, the heart of network communication.
Why header and trailer is present in network layers?
HEADERS: It is a part of an information structure that precedes and identifies the information that follows,such as block of bytes in communication.TRAILERS:It is an information typically occupying several bytes ,at the tail end of a block of transmitted data which may contain a checksum or other error-checking data useful for confirming the accuracy and status of transmission.
What is the Network layer in the OSI?
Layer 7:Application LayerDefines interface to user processes for communication and data transfer in networkProvides standardized services such as virtual terminal, file and job transfer and operationsLayer 6:Presentation LayerMasks the differences of data formats between dissimilar systemsSpecifies architecture-independent data transfer formatEncodes and decodes data; Encrypts and decrypts data; Compresses and decompresses dataLayer 5:Session LayerManages user sessions and dialoguesControls establishment and termination of logic links between usersReports upper layer errorsLayer 4:Transport LayerManages end-to-end message delivery in networkProvides reliable and sequential packet delivery through error recovery and flow control mechanismsProvides connectionless oriented packet deliveryLayer 3:Network LayerDetermines how data are transferred between network devicesRoutes packets according to unique network device addressesProvides flow and congestion control to prevent network resource depletionLayer 2:Data Link LayerDefines procedures for operating the communication linksFrames packetsDetects and corrects packets transmit errorsLayer 1:Physical LayerDefines physical means of sending data over network devicesInterfaces between network medium and devicesDefines optical, electrical and mechanical characteristics
What is the Difference between data link error control and transport layer error control in osi model?
Data link error control checks for error in each router and end-system, but transport layer error control checks for error only at the end-systems.
