Why is network layer associated with IP addressing?
The network layer uses IP addresses to determine whether or not to route a packet from one network to another. Since an IP address has two parts, the network id and the host/client id, this makes it a natural fit (IP addressing) for the network layer.
How many network addresses are there in a network with a subnet mask of 21?
One - by your problem statement, all addresses are part of the same network. The number of host addresses is 232-21 - 2, or about 2000.One - by your problem statement, all addresses are part of the same network.

What identifies both the logical host and the logical network addresses?
The IP protocol identifies both the logical host as well as the logical network addresses...........
What is a network layer?
The network layer is the third level of the Open Systems Interconnection Model (OSI Model) and the layer that provides data routing paths for network communication. Data is transferred in the form of packets via logical network paths in an ordered format controlled by the network layer. The network layer provides the functional and procedural means of transferring variable-length data sequences from a source to a destination host via one or more networks, while maintaining the quality of service functions. networkrepairs.ca
Which layer does a host process in a network?
Transport, network and link
What layer is the first point of entry for a host into the network?
Access layer
Which layers in the OSI model are host to host layers?
Transport layer is known as the host-to-host layer. Also data link layer is responsible for point-to-point or point-to-multipoint transport of data. HTH, Rajesh
How do hosts ensure that their packets are directed to the correct network destination?
Hosts ensure that their packets are directed to the correct network destination through the use of IP addresses and routing tables. When a host wants to send data, it encapsulates the packet with the destination IP address, which identifies the target device on the network. Routers then use their routing tables to determine the best path for the packet to reach its destination, forwarding it across interconnected networks until it arrives at the intended host. Additionally, protocols like ARP (Address Resolution Protocol) are used to resolve IP addresses to MAC addresses within local networks, ensuring correct delivery at the data link layer.
How many host addresses may assign when using the 128.107.0.0?
To determine the number of host addresses available in the 128.107.0.0 network, we first need to identify its subnet mask. Assuming it's a Class B network with a default subnet mask of 255.255.0.0 (or /16), the number of usable host addresses can be calculated using the formula (2^{(32 - subnet_bits)} - 2). This results in (2^{(32 - 16)} - 2 = 65,534) usable host addresses, where we subtract 2 for the network and broadcast addresses.
What layer of OSI model is switches on?
Switches are on the second layer of the OSI model (Data Link); they do filtering based on host MAC addresses. You may also see a third layer switch; they not only provide all switching capabilities but some layer three routing capabilities too.
Function of network layer?
The most simplest answer is that, the network layer routes data beyond the LAN boundary and it ues routing table with IP addresses. This the layer that your ROUTERfuntions
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
