is http a data link layer technology

It is basically a data link control facility that is required for transferring IP packets usually among Internet Service Providers (ISP) and a home user over a dial-up link. c. network. Data Link Layer. It is used for source and destination addresses. The other is routing packets by discovering the best path across a physical network. It responds to service requests from the network layer above it and issues service requests to the physical layer below it.. 2. In Next Generation SSH2 Implementation, 2009. The header in this layer provides the source and destination MAC addresses. It furnishes transmission protocol knowledge and management and handles errors in the physical layer, flow control and frame synchronization. This is done by breaking data up into data frames, transmitting them sequentially, and processing acknowledgment frames sent back to the source by the… A couple posts ago, we talked about Layer 1 of the OSI Model -- the Physical Layer.Today, we'll start our climb up the Model with a visit to Layer 2, the Data Link Layer. The services provided by the data link … The data link layer is used for the encoding, decoding and logical organization of data bits. It is the data link layer that will convert the data into binary digits such as 1 and 0 and then prepare them for the physical layer. The data link layer is the second layer in the OSI (open systems interconnection) seven-layer reference model. Which sublayer of the data link layer performs data link functions that depend upon the type of medium? The data link protocols operate in the data link layer of the Open System Interconnections (OSI) model, just above the physical layer. The data link layer's first sublayer is the media access control (MAC) layer. bits are packaged into frames at which layer of the OSI model? The data link layer is responsible for encoding bits into packets prior to transmission and then decoding the packets back into bits at the destination. The data link layer establishes and terminates a connection between two physically-connected nodes on a network. The network layer uses network addresses (typically Internet Protocol addresses) to route packets to a destination node. a. data link b. transport c. physical d. presentation ... d. changes in technology at one layer of the model don't usually affect the operation of others layers. Data Link (Layer 2) At OSI Model, Layer 2, data packets are encoded and decoded into bits. The link layer encryption process effectively protects data in transit, so it has great value in environments where the data transmission route is unsecured or potentially at risk. Data packets are framed and addressed by this layer, which has two sublayers. MAC sublayer of the data link layer e. session. Data Link Layer (2) The data link layer takes the packet from the network layer and breaks it into frames. It is an encapsulation of the TCP/IP especially designed to work with over serial ports … a. logical link control sublayer: b. media access control sublayer: c. network interface control sublayer: d. none of the mentioned The data-link layer transforms a raw communications channel into a line that appears essentially free of transmission errors to the network layer.
