MYADDRESS MAC MAC

People you want to communicate with may-or-may-not be in the same room as you. Or what if Bob is blind? He is told, вЂњyou are in Room-1 and there are other rooms in this building. Bob canвЂ™t simply вЂњspeakвЂќ and expect that Sally will be able to hear him. a router).ДЄn example of this would be if Bob is in Room-1 on the first floor of a building, and Sally is in room-x on the 20th story of that same building. I need to talk to you.вЂќ All others in the room will hear BobвЂ™s voice, but elect to ignore it once they understand that he is trying to communicate with Sally.Д«ut that entire premise breaks down if you have devices which cannot hear each other directly and instead, need some kind of relay agent to communicate (i.e. This is similar to the question, вЂњ if a bunch of people are in the same room and can all hear each other talking, how can one person communicate directly with another?вЂќ As a solution, we can provide each person with a unique name (such as Bob and Sally) and therefore Bob, when he decides to speak, can simply shout out вЂњHey Sally, this is Bob. This address would not prevent everyone else on the cable from seeing the data, but it would provide an indicator as to which specific device was the intended recipient of that data. cable) in which all devices can physically 'hear' all other devices (this is how Ethernet works) the designers determined that each device simply needed a unique identifier (MAC Address) with which they could address their data.

If everyone could see/hear everyone else, when Device-A recognized that another device on the cable was speaking.how could Device-A determine if it should be the recipient of that conversation.or it should ignore it?.

If everyone could see/hear everyone else how could Device-A transmit to Device-B and have it understood by all other devices on that cable (which were listening to that conversation) that they should ignore what they were seeing.

If everyone could see/hear everyone else, how could one device transmit without overriding someone else's current transmission.

Based on that, the developers of the protocol were trying to answer questions like: a cable) onto which several devices could be physically connected and all have visibility to the energy (electrical signals) transmitted onto that cable. Robert Metcalf who was working with Xerox at the time) had created a network type (i.e.

MYADDRESS MAC MAC

The developers of MAC addresses (specifically Dr. IP Addresses and MAC addresses were developed around the same time (circa 1974) but were answers to two, very different problems. What is the reason behind why a device (connected to an Ethernet network) needs to have two identifiers? This post is my attempt to answer that question. For those who begin their studies of computer networking, a common question is the one posed above in the title.
