No. Frames are used on the data-link (layer 2) layer. Packets are used at the Network (layer 3) layer.

Which layer resizes frames to match the receiving network?
resize layer
Do frame encapsulate packet or packete encapsulate frames?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".

Suppose your network is connected to another network via a router which OSI model layer provides the information necessary to direct data between the two networks?
The Network layer is where the frames of the Data Link layer become packets. The best way to think of the Network layer is as the mailroom clerk of the OSI model. The clerk receives mail and directs it to the appropriate couriers. In similar fashion, the Network layer translates the frames it receives from the Data Link layer into more logical packets which can be routed to other networks (like sending it to a courier). At the Network layer, you can begin to actually communicate across a Network, but the service is called "unreliable" because no connection can be established. Communication over the Network layer is something like throwing a message in a bottle into the sea - you cannot verify that the other person ever reads the message. It should be noted that most of what we call "routing" occurs at the network layer - that is, network traffic is routed from one network to another at this layer, allowing for inter-network (as opposed to intra-network) communication.

What is the difference between a layer 2 and a layer 3 switch?
The difference between Layer 2 and Layer 3 switching is the type of information inside the frame that is used to determine the correct output interface. With Layer 2 switching, frames are switched based on MAC address information. With Layer 3 switching, frames are switched based on network-layer information.
Which layer is responsible for converting data packets from the Data Link layer into electrical signals?
This protocol would be the NIC (Network Interface Card). The NIC takes frames from layer 2 and converts them into electrical siginal's
What layer is IP address defined?
The Layer 3(Network Layer) is associated with IP addressing.Because,It converts the frames into packets and address them to send across the other network through intermediary devices.While transferring across the other network's have to know about the destination IP address and also source IP address's deals with IP address.
Which layer of the OSI model encapsulates Network layer pockets?
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
Which layer is absent in broadcast network?
network layer
Describe the type of services provided by data link layer to the network layer. list three MAC sub layer protocols?
Data Link layer:Data link layer has several functions to perform they are providing a well defined service to the network layer, determining how the bits of the physical layer are grouped into frames, dealing with transmission errors, regulating the flow of frames so that slow receivers are not swamped by fast senders, and general link management.Services provided to the network layer:The principal service provided by the data link layer to the network layer is the transmission of data from the source network layer to destination network layer. This can be accompolished in 3 ways:1. Un acknowledged connectionless service.2. Acknowledged connectionless service.3. Connection oriented service.Unacknowledged connectionless service consists of having the source machine send independent frames to the destination machine without having the destination machine acknowledge them. This is used where the re is a very low chance of transmission errors.In Acknowledged connectionless service the source machine send the frames indepenedently to the destination machine, but with acknowlegement to each and every frame from the destination machine.In connectin oriented service a connection is established between the source and the destination until all the data is transfered.
What is the function of routing in the network OSI layer3?
The whole point of the network layer, and layer 3 devices, is to move packets between separate networks. Layer 2 devices on the other hand (switches), only move frames using only the data link layer between hosts in that same network. Without layer 3 devices (routers or gateways), there could be no communication between separate interconnected groups of computers.
