list the tcp/ip protocol suite layer that preforms each of the following:
defintion of a signal's electrical characteristics
error detection
definition of a signal's electrical characteristics
Layer 1 of the tcpip:
The physical layer defines the electrical and physical specifications of the device. The physical layer defines the relationship between the device and the transmission medium, such as copper or fiber optic cable.
This includes pin layouts, voltages, cable specifications, hubs, repeaters, network adapters, host bus adapters (HBAs used in storage area networks), and more. The main functions and services performed by the physical layer are:
1) Establishing and terminating the connection with the communication medium.
2) Participation in a process in which communication resources are effectively shared among multiple users (for example, dispute resolution and flow control).
3) Modulation or conversion between the digital data representation in the user device and the corresponding signals transmitted over the communication channel; these are signals operating over physical cabling (such as copper and optical fiber) or over a radio link.
