To transmit digital data over physical media, the bits must be converted into physical signals. This is achieved through encoding (for digital-to-digital conversion) and modulation (for digital-to-analog or analog-to-analog conversion).
A computer network is a digital telecommunications network that allows nodes to share resources. In these networks, computing devices exchange data with each other using connections between nodes. These data links are established over cable media such as twisted-pair or fiber-optic cables, or wireless media such as Wi-Fi or cellular networks. To transmit digital data over physical media, the
Physical transmission channels are prone to errors caused by noise and interference. The Data Link Layer implements mathematical mechanisms to identify and correct these errors. In these networks, computing devices exchange data with
Manages bit stream transmission over physical mediums (cables, radio waves). The Data Link Layer implements mathematical mechanisms to
Manages, establishes, and terminates connections between applications.
: Features a solid central copper conductor surrounded by insulation and a braided shielding layer. It offers higher bandwidth than twisted-pair and is standard in cable television networks.
Detailed explanations of Simplex (one-way), Half-Duplex (two-way, one at a time), and Full-Duplex (simultaneous two-way) communication.
