Data communication is crucial to our modern world. It connects us to the devices and services we depend on. It includes a variety see it here of techniques and media which dictate how information is sent from one end to another. Understanding how it works helps us to design a highly efficient and reliable networks that provide the benefits of greater connectivity including increased efficiency and productivity in business, and innovations within automation.
Data communication is the transfer of data between computers through channels or medium. This can be done over cable, satellite signal, radio frequency, or wirelessly. A device or person who transmits data is the sender while the computer that receives the data is known as the receiver. A data communication network can have more than two computers involved in a communication.
Multiplexing and demultiplexing are effective technology for communication that allows multiple signals to be transmitted over an medium at once, thus optimizing bandwidth utilization and reducing costs. Both of these processes require special hardware that can combine and separate signals. This function is typically performed by custom integrated circuits, that are found in a wide variety of communication products, such as cell phones, computers and printers.
Full-duplex communication is a type of data communication that allows simultaneous two-way communication between two devices. This type of communication is more complex than simplex communication because it requires the ability of sending and receiving data simultaneously.
