What address does Ethernet use to forward frames?
Frame Forwarding (1.2.
1) On Ethernet networks, frames contain a source MAC address and a destination MAC address.
Switches receive a frame from the source device and quickly forward it toward the destination device..
Does Ethernet use IP address?
While IP is the only addressing protocol used by Ethernet, Ethernet networks use two types of data transmission: TCP and UDP.
Do switches use IP addresses?
Unmanaged and layer 2 network switches do not have an IP address, whereas managed switches and layer 3 switches do. A network switch with an IP address is required for Telnet which allows remote access to the switch. The IP address of a switch can be found via the router or an IP scanner.
What is MAC address explain with example?
Stands for “Media Access Control Address,” and no, it is not related Apple Macintosh computers. A MAC address is a hardware identification number that uniquely identifies each device on a network. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e. …
Can two devices have same MAC address?
If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. … Duplicate MAC Addresses separated by one or more routers is not a problem since the two devices won’t see each other and will use the router to communicate.
What is a frame called that is intended for only one individual computer?
the destination IP address of a frame and the port it was received on. unicast. What is a frame called that is intended for only one individual computer? broadcast. unicast.
What component of the computer contains a MAC address?
A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
How do Ethernet switches know where to send the frames they receive?
The frame is sent onto the network where an Ethernet switch checks the destination address of the frame against a MAC lookup table in its memory. The lookup table tells the switch which physical port, i.e., RJ45 port, is associated with the device whose MAC address matches destination address of the frame.
Why does the destination address come first in Ethernet frame?
In order to work efficiently, the receiver wants to read the address of a packet very easy, perhaps even with the help of hardware (FPGA or ASIC). And for this, it is handy to have this address at the very beginning.
What are the different types of switches?

Which device receives a frame and reads the source and destination MAC addresses before forwarding the frame out another port?
switchHow does a switch “learn” MAC addresses? It reads the source address and keeps a record of which port the sending computer is on.
How do switches work in networking?
A network switch is a device that operates at the Data Link layer of the OSI model—Layer 2. It takes in packets being sent by devices that are connected to its physical ports and sends them out again, but only through the ports that lead to the devices the packets are intended to reach.
How do Ethernet switches know which ports to forward Unicast frames on?
Switch forwards a known unicast frame only from the port which is directly connected to the destination address of that frame while it forwards an unknown unicast frame from all of its ports, except the port on which it arrived. When PC-A sent a frame to PC-B, the destination address (2222.2222.
What are switches used for?
A switch is used in a wired network to connect to other devices using Ethernet cables. The switch allows each connected device to talk to the others. Wireless-only networks do not use switches because devices such as wireless routers and adapters communicate directly with one another.
Why MAC address is required when IP address is there?
MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
