Intel stopped using numbers (such as 286, 386, etc.) to identify their processors and switched to using names (such as Pentium, Itanium, etc.) for a number of reasons.
The numerical naming approach had became complicated and challenging for consumers to understand, which was one reason for the move. Consumers found it more difficult to decide which processor was the most powerful or best suited for their needs as the variety of processor models grew.
Another reason was that using names helped Intel to better distinguish its CPUs from one another and to explain to customers the benefits of each model. Intel could highlight the distinctive qualities of each processor and establish a stronger corporate identity by employing names.
Finally, using names gave Intel additional flexibility and the ability to adjust to shifting market conditions. Intel could more readily release new models and phase out older ones if they had names.

when does your computer need to know the mac address of a host you are connecting to, how does it determine it?
Your computer needs to know the MAC (Media Access Control) address of a host when it wants to communicate with that host over a network.
Each device on a network is given a specific identifier called a MAC address, which is used to identify the device and initiate contact with it.
A computer can find the MAC address of a host it wants to connect to in a number different ways. One method is for the computer to broadcast a request over the network for the host's MAC address. All networked devices receive this message, but only the host with the desired MAC address will reply.
A computer can also use the Address Resolution Protocol to find out a host's MAC address (ARP).A computer can use ARP to identify the MAC address of a host based on its IP address when it wishes to interact with a host on the same network.
The MAC address of a host can also be found by a computer by looking up the address in a cache or table of previously known MAC addresses. In order to search up a host's MAC address fast in the future without having to broadcast a message or utilize ARP, a computer caches the host's MAC address when it connects with it.
