What is the Difference Between An Ethernet Hub and a Switch?

Ethernet hubs and switches are networking devices that connect computers [and IP devices] together. A hub is basic, offering simple data transmission capabilities to MAC addresses over Layer1.

Does Hub Use IP Address?

As others have said, hubs don't use IP or MAC addresses. They just mirror everything from every port to all other ports. Think of it this way. A computer can't just say "hey I want to send this data over to that computer over there." It has to be more specific by specifying an address.

Does a Hub Use MAC Address?

An ethernet HUB does not care about MAC addresses. This is in contrast to an ethernet SWITCH. So the HUB just copies the packet whenever it receives one, and sends a copy on all other interfaces. Obviously, this can result in congestion, in which case some packets are discarded.

What does a Hub Do?

A Hub is the simplest of those switch, router, and bridges in Networking. In general, a hub is the central part of a wheel where the spokes come together. Hubs cannot filter data so data packets are sent to all connected devices /computers and do not have intelligence to find out best path for data packets.

Do Routers Use IP Addresses or MAC Addresses?

These create a logical address structure that makes it possible to build networks of networks, ultimately covering the earth. So your router has a MAC address so the various machines can talk to each other using Ethernet, and a IP address to communicate with the world.

Does a Hub Assign IP Address?

And hubs? Nope. They dont have IP addresses because it just doesnt make sense.

What is the Role of a Hub in a Network?

Hub is commonly used to connect segments of a LAN (Local Area Network). A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network.

5.3.1.3 Packet Tracer – Identify MAC and IP Addresses

Why would the MAC addresses appear in this order? A switch can begin forwarding a frame to a known MAC address more quickly if the destination is listed first. Every time that the PDU was sent between the 10 network and the 172 network, there was a point where the MAC addresses suddenly changed.

How are MAC Addresses Usually Presented?

The MAC address is a 12 digit hexadecimal number that is most often displayed with a colon or hypen separating every two digits (an octet), making it easier to read. Example: A MAC address of 2c549188c9e3 is typically displayed as 2C:54:91:88:C9:E3 or 2c-54-91-88-c9-e3.

What do MAC Addresses Tell You?

MAC Address or media access control address is a unique ID assigned to network interface cards NICs. It identifies the hardware manufacturer and is used for network communication between devices in a network segment.

Are MAC Addresses Hierarchical?

With MAC addresses, there is no hierarchy, and thus packet forwarding would not be possible. So, MAC addresses are not used for packet transfer.

Why does One Port have Two MAC Addresses?

A switch can have multiple MAC addresses associated with a single port. This is common when the switch is connected to another switch. The switch will have a separate MAC address table entry for each frame received with a different source MAC address.

What is a MAC Address Displayed In?

The most common format for displaying a MAC address is using six groupings of two characters separated by a hyphen or colon. i.e abcdef123456. Computers, phones and mobile devices may have more than one network adapter, and so may have more than one MAC address.
