During encapsulation process what occurs at the data link layer?
The physical address is added
What addresses are added to the transport layer headers during the encapsulation process and what are they used for?
port numbers
During the encapsulation process which identifiers are added at the transport layer?
source and destination port number or two applications communicating the data
What identifiers are added at the transport layer during the encapsulation process?
two applications communicating the data
What are the steps of encapsulation?
Encapsulation is the process of adding header information to the layers' data "payload". As the "payload" is passed from one TCP/IP (or OSI) layer to the next, encapsulating layer information is wrapped around the data. So, for example, if the application layer produces a data payload for transmission, it encapsulates it with application-layers headers, which then gets passed to the presentation layer. The presentation layer does the same and so down the protocol stack before transmission across the physical media. At the destination, the process is reversed by way of de-encapsulation where the headers are stripped-off by each matching layer at the destination. 1. Application, Presentation and Session layers create data. {Encapsulation headers added by layers} 2. Transport layer coverts data into segments for transport across the network. {Encapsulation headers added by layer} 3. Network layer converts segments into packets (or Datagrams). {Encapsulation headers added by layer} 4. Data Link layer converts packets (and datagrams) into Frames and the Data Link header is added. {Encapsulation headers added by layer} 5. Physical - frames are converted into bits for transmission over the physical media.{Encapsulation headers added by layer}
A user sends an HTTP request to a web server on a remote network During encapsulation for this request what information is added to the address field of a frame to indicate the destination?
When a user sends an HTTP request to a web server on a remote network, the information needed to perform the action is added to the address field of a frame to indicate the destination during encapsulation.
During the encapsulation process what occurs to data link layers?
the physical address is added
What is a primary function of the trailer information added by the datalink later encapsulation?
it is used for error detection
How does data encapsulation allows data to be transported across the network?
The physical address is added
What is network layer of osi reference model?
The network Card(NIC) is on Layer 2, but the connector on the NIC is considered Layer 1 because the connector is considered a physical connection. Layer 1 ------Physical Layer 2 ------Data According to Network+ the answer is Physical.
What is a primary function of the trailer information added by the data link layer encapsulization?
support error detection =)
What are two primary responsibilities of the Ethernet MAC sublayer?
MAC provides physical addressing. The BIA (Burn In Address) which is stored in RAM when the computer boots up is added to each frame that is created as the source mac address. But to answer your question, the MAC layer does the following: Data Encapsulation and Media Access Control.
