The MAC address that is built into your network card cannot be changed. Or can it$?$ It is possible to set your own local MAC addresses with suitable software and use the IEEE$-$defined U$/$L $($Universal$/$Local$)$ bit in the MAC address Some networking vvsoftware can make use of this feature to define MAC addresses. Describe one example of such an approach to networking. Listed and explained a few types of

software that can define MAC addresses.

Described an example of such MAC

address identifier to networking.

Clearly defined ATM and Ethernet

network.

Described, with example the relationship

of Asynchronous Transfer Mode $($ATM$)$

with the Ethernet networks.

Shown the function of NAT.

Provide the evidence of the possibility of

connecting to an alternative router that

supporting the organization's network

with the Internet.

$3.$ Explain the relationship of Asynchronous Transfer Mode $($ATM$)$ networks to the Ethernet networks that you have studied.

$4.$ Companies apply a policy to use two or more routers for connecting the company$$s network to the Internet to provide some redundancy in case one of them goes down. Is this policy possible with NAT? Explain your answer.
