The role of the physical layer in transmitting data on the network can be explained as follows:
Creating Signals
The primary function of the physical layer is to create the signals that represent the bits in each frame onto the media. This layer is responsible for converting the digital data into analog signals that can be transmitted over the physical medium such as copper wires, fiber optic cables, or wireless signals. The physical layer takes the digital bits from the upper layers and converts them into a series of electrical or optical signals that can be transmitted over the network.
Encoding and Decoding
The physical layer also provides encoding and decoding mechanisms that are used to ensure that the data is transmitted accurately over the network. For example, the physical layer can use Manchester encoding, which is a technique that uses transitions in the signal to indicate the start and end of a bit. The receiving device can then decode the signal to determine the bits that were transmitted.
Media Access
The physical layer also controls media access, which refers to the process of granting devices access to the physical medium. This layer defines the rules that devices must follow when transmitting data over the network. For example, it can define the order in which devices can transmit data or the amount of time each device has to wait before transmitting.
Physical Addressing
Although the physical layer does not provide logical addressing, it does provide physical addressing to the devices. Each device on the network has a unique physical address, which is used to identify the device on the network. This physical address is also known as the MAC address.
Conclusion
In conclusion, the physical layer is responsible for creating signals that represent the bits in each frame onto the media, providing encoding and decoding mechanisms, controlling media access, and providing physical addressing to the devices.

The primary role of the physical layer in transmitting data on the net...
Physical layer is the lowest layer of OSI model. The main function of the physical layer is to represent the data in the form of bits and to encode these data bits into the signals. These signals are then transmitted to the network.
Thus, option 1 is correct answer.
Thus, option 1 is correct answer.
