Discuss the need or lack of need for a network layer OSI layer 3 in a broadcast network?
The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another. In a broadcast network, routing is not needed. A transmission from any attached station is received by all other attached stations. Other functions,such as sequencing, flow control, error control, can be done at layer 2. The MAC sublayer is responsible for addressing across the LAN. With the Data link layer and its sublayers (MAC & LLC), no network layer is needed.
Which layer of OSI Model is the network interface card of LAN related to?
The network interface card (NIC) of a Local Area Network (LAN) primarily operates at the Data Link Layer (Layer 2) of the OSI model. This layer is responsible for node-to-node data transfer and framing, enabling the NIC to manage how data packets are placed on and received from the physical medium. Additionally, the NIC also interacts with the Physical Layer (Layer 1), which deals with the physical connection and transmission of raw bits over the network medium.
Name three layers of the OSI standard and describe their function?
The three layers of the OSI standard are application layer, transportation and Network layer. Network layer provides the electrical and mechanical interface to network medium, network layer handles routing and forwarding of data. The transport layer ensures data is successfully sent and received between two nodes..
Does the network map utility use a new protocol called link layer topology discovery to discover information about the network and the devices attached to it?
true
Which layer is absent in broadcast network?
network layer
Which network layer protocol is responsible for routing packets on the network?
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
What is the function of the network access layer?
The Network Access Layer is the lowest layer of the TCP/IP protocol hierarchy. The protocols in this layer provide the means for the system to deliver data to the other devices on a directly attached network. It defines how to use the network to transmit an IP datagram. Unlike higher-level protocols, Network Access Layer protocols must know the details of the underlying network (its packet structure, addressing, etc.) to correctly format the data being transmitted to comply with the network constraints. The TCP/IP Network Access Layer can encompass the functions of all three lower layers of the OSI reference Model (Network, Data Link, and Physical).
What layer programs access the network?
Network Layer

Which layer is the network support layer?
Physical, Data link and Network layers make the Network Support layers.
What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
Which layers of the OSI Reference Model provides for inter network connectivity?
Network Layer
