Answer:
Physical / Data link layer
Explanation:
If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.
The Open Systems Interconnection model (OSI model) has seven layers each with its own function.
The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.
The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.
The reason why it wouldn't be practical for big corporations to build a network with only one (1) transmission medium is: C. because they require a combination of transmission media types to function properly.
A big corporation can be defined as a corporate organization that has facilities and owns (controls) assets that are used for the manufacturing of goods and services in at least one (1) country, other than its headquarter (home office) located in its home country.
This ultimately implies that, a big corporation is a corporate organization that owns (controls) its business operations in two or more countries.
In light of the above, a big corporation require a combination of multiple transmission medium or transmission media types such as the following, in order for them to function properly, effectively, and efficiently:
