Exploring the OSI Physical Layer
The overall task of the Physical layer is that the Physical Layer creates a connection between a device and the transmission medium. The Physical Layer deals with the physical attributes of the connection that’s used to transmit data across a single link. The physical layer also encodes the data for transmission and determines the shape of the connectors and the types of mediums used for transport. The modulation of the bit encoding is one of the best ways to determine how fast data can be transmitted across the link, whether that link is wireless, copper, or fiber optic. So, what are some of the things the Physical Layer does? 1. Converts signal from one form to another so it can be transmitted 2. Bit-by-bit delivery 3. Bit synchronization for synchronized serial communication 4. Start signals and stop signals for asynchronous serial communication 5. Carrier sensing...
