When creating a packet how does the network layer determine the size of the packet?

The Network layer (Layer 3, typically IP) will receive a segment from the Transport layer (Layer 4, typically TCP or UDP), and will add its own header to it to create a packet. The size of the packet will thus always be the size of the segment plus the Network layer header, the same as when the next layer down (the Data Link layer, layer 2, typically Ethernet) encapsulates the packet into a frame for transmission.

At which OSI layer does a computer determine if the packet is intended for it on a 10BaseT Network?
The Network Layer
What is a network layer data gram?
A packet.A packet.A packet.A packet.
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.
The PDU at the Network layer is called?
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.
Which layer determines the route a packet takes from sender to sender to receiver?
Network Layer
Why do you need a 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. Without the network layer it would not be possible to send a packet outside of your own local network.
Do frame encapsulate packet or do packet encapsulate frame?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
What protocol does PPP use to identify the Network layer protocol?
Network Control Protocol is uses to identify the Network layer protocol used in the packet
What are the advantages of gateway?
a gateway can translate information between different networks data formats or network architecture. most gateways operate at the application layer. it can also be operated on network or session layer. by: talha jamal and farhan moin (kinpoe)
Do frame encapsulate packet or packet encapsulate frame?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
Why is it that an ICMP packet does not have source and destination port?
Because ICMP is on the network layer
Is it possible for a network layer to provide connection oriented packet switching?
its depend on which protocol used in transport layer
