IEEE has divided the Transport layer into two sublayers?
No. It is the Data Link layer that IEEE has divided into two sublayers. The Data Link layers are Logical Link Control and Media Access Control.
What are two functions of the data link layer?
What are two functions of the data link layer? (Choose two.) It segments and reorders the data. It exchanges data between programs that are running on the source and destination hosts. ***It controls how data is placed onto the media. It generates signals to represent the bits in each frame. ***It encapsulates each packet with a header and a trailer to transfer it across the local media. ============================ 1. Data Link layer do not reorder data - this is the job of Transport Layer 2. Programs are at Aplication Layer 4. Physical Layer generate signals
Which two layers of the OSI model have the same functions as the TCP model network layer?
physical & data link layers
Why Bridges operate at Layer 2?
Layer 2 of the OSI model, the Data Link Layer is composed of two sublayers, the lower being the MAC layer that regulates how computers access information on a network and transmit it. A bridge connects two networks, or two sections of a LAN, and works at the Data Link Layer to regulate it.
In which two layers of the osi model do NIC's belong?
NIC's can perform in the Data Link Layer of the OSI model. However, they can also perform services in the Physical Layer.(Network+ Guide to Networking Answer)Physical and Data Link layers
Which particular layer of OSI model is not required if two devices communicate at the same network?
In this situation Network Layer may not be required. Data Link Layer can handle communication process. If two devices are communicating from different networks then Network Layer a is must. In this situation Data Link Layer is not enough for completing the communication process as it lacks Routing ability which is the primary function of Network Layer.
What are two primary responsiblity of ethernet mac sublayer?
No, frame delimiting is a primary responsibility of the Logical Link Control sublayer of the Data Link Layer.. Data link layer exists of 2 sublayers; Media Acces control Sublayer (MAC) & Logical Link Control sublayer (LLC)
If data link layer detect error why do you think we need transport layer?
because in the data link layer two routers communitate directly via a physical channel , whereas at the transport layer this physical channel is replaced by the entire subnet. In the data link layer ,it is not necessary for a router to specify which router it wants to talk to each outgoing line uniquely specifies a panicular router . In the transport layer explicit addressing of destinations is required.
What is difference between Transport layer and data link layer?
The data link layer handles communication between systems on the same local network. The network layer handles communication between systems on different local networks and allows those packets to be routed between the two. The data link layer would allow two machine on network a to talk to each other or two machines on network b to talk to each other. This communication takes place using the physical/MAC addresses of the machines. The network layer is what allows a machine on network a to talk to a machine on network b using logical address like IP addresses.
Which two data link layer protocols are used in packet-switched WAN networks?
Atm frame relay
What are two data link layer protocols are used in packet-switched WAN networks?
atm and frame-relay
A Device that operates at either the data link layer or the network layer and connects two nodes on separate segments by making a direct connection is called a?
bridge
