converting digital data to digital signal.
character set
The digital encoding techniques are of two types--Polar and Bipolar. The polar encoding are--RZ(Return to Zero), NRZ (No RZ) , Manchester and Differential Manchester. Bipolar encoding are--AMI ( Alternate Mark Inversion) and BnZS ( Bipolar n Zero Substitution).
encoding means conversion of data into bit strem..
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
I assume you're talking about portion of the OSI model that handles character-encoding such as ASCII. It is the Presentation Layer of the OSI model.
Wide Area Networks (WANs) commonly use several encoding schemes, with one of the most prevalent being the Packet Mode, where data is encapsulated into packets for transmission. Other encoding schemes include Frame Relay, Asynchronous Transfer Mode (ATM), and MPLS (Multiprotocol Label Switching), which help optimize data flow and ensure efficient delivery over long distances. Additionally, depending on the technology, WANs may also utilize encoding techniques like Manchester or Differential Manchester encoding for signaling purposes. These schemes facilitate reliable communication and enhance the efficiency of data transfer across the network.
Unicode is a standardized character encoding system that assigns a unique numeric code, known as a code point, to each character across different languages and symbols. This code point is then represented in digital form using various encoding schemes, such as UTF-8, UTF-16, or UTF-32, which specify how these numeric values translate into binary code. By using a consistent encoding system, Unicode enables the representation and interchange of text in multiple languages and scripts across different platforms and devices. This universality allows for seamless communication and data processing in a globalized digital environment.

See SSH and SSL is the way in which information is percieved and processed.
Number systems used mainly in encoding, cryptography, digital computing.
Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signals.Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signalsEncoding : Digital or Analog data --> Digital signalmodulation : Digital or Analog data --> Analog signal
A lack of high-frequency components means that less bandwidth is required for transmission. In addition, lack of a direct-current (dc) component means that ac coupling via transformer is possible. The magnitude of the effects of signal distortion and interference depend on the spectral properties of the transmitted signal. Clocking: Encoding can be used to synchronize the transmitter and receiver. Error detection: It is useful to have some error detection capability built into the physical signaling encoding scheme. Signal interference and noise immunity: Certain codes exhibit superior performance in the presence of noise. Cost and complexity: The higher the signaling rate to achieve a given data rate, the greater the cost. Some codes require a signaling rate that is in fact greater than the actual data rate
