What would happen if two computers had the same Ethernet address and were on different networks?
If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. On an Ethernet LAN, this will cause a high number of collisions. Duplicate MAC Addresses on the same LAN are a problem.
How many Ethernet addresses are there?
The IEEE 802 MAC address originally comes from the Xerox Network Systems Ethernet addressing scheme. This 48-bit address space contains potentially 248 (over 281 trillion) possible MAC addresses. The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers.
What happens if two devices on the same ethernet network determine the network is free but attempt to transmit data at exactly the same time?
This describes how the Ethernet protocol regulates communication among connection points….
| Q. | This is what happens if two devices on the same Ethernet network determine the network is free, but attempt to transmit data at exactly the same time. |
|---|---|
| A. | overlap |
| B. | crossover |
| C. | collision |
| D. | none of the above |
What is better router or switch?
Comparing an Ethernet Switch vs. Router. While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. If you have the need for more connections, an Ethernet switch may be a better option over a hub.
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.
What is the difference between IP address and Ethernet address?
This address is the identifying mark that lets a networked computer communicate with the Internet. The ethernet address is how we can associate an “IP address” to an individual compute — without this– number, there’s no way to access any servers, websites, email, etc. This is not the ethernet address.
What are the 3 types of destination ethernet addresses?
There are three types of Ethernet addresses:
- unicast addresses. Unicast addresses represent a single LAN interface.
- multicast addresses. Multicast addresses represent a group of devices in a LAN.
- broadcast addresses. Broadcast addresses represent all device on the LAN.
