Three types of methods 1-Simplex 2-Half Duplex 3-Full Duplex 4-Serial
It means the data can be transfer serially.i.e ,one by one. So it is less in speed.
Assuming that by serial technologies you mean serial communication, here are some: USB - Universal Serial Bus RS232C - The original serial protocol
serial and parellel transmission
Your serial data line is having problems talking between the models. Most of the time these are caused by loss of power/ground on the serial data line.
The 8251 A is a programmable communication interface used for serial data communication. Its primary functions include the conversion of parallel data from a microprocessor to serial data for transmission and vice versa for reception. It supports various communication protocols, provides error detection, and allows for configurable baud rates. Additionally, it facilitates the management of control signals and handshaking for effective data transfer between devices.
it is a communication port which recives and sends data serialy
4 total 2 for data and 2 for power
Serial processing in operating system is one of the types of data processing in the computer. The data is read by the CPU, analyzed, processed and then executed in this system.
(DCE) Data Communications Equipment (the serial interface responsible for clocking) (DTE) Data Terminal Equipment (the serial interface designed for connection to a CSU/DSU to outside digital communication service)
Can span longer distance, fewer data paths, flexibility in design, error detection,
Parallel data transmission is faster compared to serial data transmission. The speed of a parallel link is equal to the number of bits sent multiplied by the bit rate of each individual path.
