What is the lowest layer of the osi model at which lans and wans support the same protocols?

What is the lowest layer of the OSI model at which LANs and WANs support the same protocols?

LANs and WANs supports same protocol at the “ Layer 3 ” of OSI model. Which layer of the OSI model do routers and firewalls operate at? Routers operate on the third layer of the OSI Model, the Network -Control Layer.

Explanation:

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
