How do bridges keep track of whether they should forward or filter frames?
they maintain a filtering database that identifies which frames can be filtered and which should be forwarded, based on their destination MAC address.

Which devices can filter network frames?
Devices that can filter network frames include routers, switches, and firewalls. Routers filter frames based on IP addresses and routing protocols, while switches can filter frames at the data link layer using MAC addresses. Firewalls provide a more comprehensive filtering capability by examining both frame and packet data to enforce security policies. Additionally, intrusion detection systems (IDS) and intrusion prevention systems (IPS) can also filter frames for security purposes.
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.
Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?
Switches and Bridges
Blank Are devices that connect two network segments by analyzing incoming frames and making decisions about where to direct them based on each frame MAC address?
bridge
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.
How do bridges and switches dynamically create their table?
Bridges and switches learn and filter MAC addressses into memory over time thereby creating a table of Mac addresses. Bridges build a memory table of MAC addresses they get from segments. Switches build tables based on switch port numbers to MAC addresses instead of segment numbers.
What is the IEEE VLAN standard?
The IEEE VLAN standard, specifically IEEE 802.1Q, defines a method for tagging Ethernet frames to support Virtual Local Area Networks (VLANs). This standard allows network administrators to segment a physical network into multiple logical networks, enhancing security and traffic management. By adding a VLAN tag to frames, devices can identify and segregate traffic based on defined VLAN IDs, facilitating better organization and efficiency within network infrastructures.
Do Brouters combine characteristics of bridges and routers?
Yes, Brouters combine characteristics of both bridges and routers. They operate at both the data link layer (Layer 2) and the network layer (Layer 3), allowing them to perform tasks such as filtering and forwarding data packets based on MAC addresses like a bridge, while also routing packets based on IP addresses like a router. This dual functionality enables Brouters to efficiently manage network traffic in environments with mixed protocols.
Is 64 and 65 Chevelle frames and El Camino frames the only frames that will fit my 65 El Camino?
A standard Chevelle frame will not fit an El Camino as it was based on the station wagon frame
Name 2 networking devices that transmit packets based on MAC address?
A MAC address is used as a unique identifier that is assigned to network interfaces. Two networking devices that transmit packets based on MAC addresses are switches and bridges.
