Frames contains information used at the data link layer of the OSI model. When your frame arrives at a switch for instance, the switch will read the frame information, as the following information is contained within:
Vlan information - your switch can determine what the source vlan is. As the ports on your switch may not all be in the same vlan, the switch needs to know what vlan it needs to send the packet on eg: You have two vlans on the switch. You want to communicate to another computer on another switch and the connection between the switches is a trunk, the sending switch will include the vlan information in the frame so the receiving switch knows where to send the frame when it receives it. This field also contains quality of service information and tells the switch which output queue to use when sending the packet.
Mac Address - switches, unlike the old hubs, know what pc is connected to what port, and will send normal traffic between computers only to the destination computer and not broadcast it over all the ports. It builds a mac address table which contains two key pieces of information. The port number and the mac address of the pc connected to that port. As the mac address information is contained in the frame the switch knows what the mac address of the destination pc is. It looks up the information in the mac table and then sends the frame to the port where the destination computer is connected to.
Frame type - this information tells the receiving computer what type of frame it is receiving and is two octets long.
Frame check sequence - this contains a 4 octet cyclic redundancy check value and is used to check for frame errors or corrupt data.

What is a primary purpose of encapsulating packets into frames?
FACILITATE THE ENTRY AND EXIT OF DATA IN MEDIA
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".

What type of bridge can package frames of one format into the format of another?
encapsulating
What is the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
Are frames in the network layer?
No. Frames are used on the data-link (layer 2) layer. Packets are used at the Network (layer 3) layer.
What is frame discuss its classification?
In the context of computer networking, a frame is a data unit transmitted over a computer network. Frames are classified based on the protocol layer they belong to, such as data link layer frames (e.g., Ethernet frames), network layer frames (e.g., IP packets), and transport layer frames (e.g., TCP segments). Each type of frame serves a specific purpose in transmitting and delivering data across the network.
What is the PPPOE protocol about?
The Point-to-Point Protocol over Ethernet or the PPPOE is a network protocol for encapsulating PPP frames inside Ethernet frames. The PPPOE term is something used confusingly to refer to either a modem to router protocol and/or the DSL side of things.
What is the Packet switching?
packet switching is nothing but the process of converting frames of data into small packets by using some of the algorithms...............
Do frames encapsulate packets?
Frames encapsulate packets. When a packet arrives at the data link layer, the entire thing, header, data, and all, is used as the data field of a frame. The entire packet is put in an envelope (the frame) so to speak (assuming it fits). Citiation: "Computer Networks". By Andrew S. Tanenbaum
What is the purpose of using cat picture frames?
Cat picture frames are a popular design for animal related frames. The purpose of using them is to reveal a person's affection towards cats, or to simply reveal a cute, and typically humorous design.
