DIGITAL TO DIGITAL CONVERSION IN DCN
DIGITAL TO DIGITAL CONVERSION Digital-to-digital encoding is the representation of digital information by a digital signal. When binary 1s and 0s generated by the computer are translated into a sequence of voltage pulses that can be propagated over a wire, this process is known as digital-to-digital encoding. Three techniques used for this conversion …

MODES IN THE PHYSICAL LAYER IN DCN
MODES IN THE PHYSICAL LAYER The direction of data flow between two communicating devices and how the communication channel is shared. The primary modes are simplex, half-duplex, and full-duplex. 1. Simplex Mode: - In simplex mode, communication occurs in one direction only, and it is unidirectional. One device is the sender, and the other is th…

Digital Transmission in the physical layer in DCN
Digital Transmission in the physical layer Digital transmission converts digital data into signals suitable for transmission over a physical medium. Key aspects of digital transmission: 1. Digital Signals: - In digital transmission, data is represented as discrete, binary signals. These signals can take on two voltage levels, often re…

PERFORMANCE IN THE PHYSICAL LAYER in DCN
PERFORMANCE IN THE PHYSICAL LAYER The performance of data communication in a network refers to how effectively and efficiently the physical medium facilitates the transmission of data between devices. Some key factors and metrics associated with the performance of the Physical Layer: 1. Data Rate (Bit Rate): the rate at which bits are transmitte…
