please help me::

If IoT devices are using the following networks, a) If the above IoT network uses the IEEE 802.3 (Ethernet) Physical Layer media alternatives that are: use 10Base5, 10Base2, 10BaseT and 10BaseFX. What will be the Medium used, the Maximum allowed Length, and the Tpology? b) Repeat (a) if we use Fast Ethernet c) Repeat (a) if we use Gegabit Ethernet d) An Ethernet MAC sublayer receives 1510 bytes of data from the upper layer. Can the data be encapsulated in one frame? If not, how many frames need to be sent? What is the size of the data in each frame?
