Data communication is the essential element that connects us with the devices and services we depend on in our connected digital world. It covers a range of techniques and media that dictate how information is transmitted from one end to another. Understanding how this works can help us design efficient and reliable networks that deliver the benefits of greater connectivity, including improved efficiency in business in productivity, as well as technological advancements in automation.
The premise of data communication is the transmission of data from one computer to the other via an intermediary or channel. This could be done through cables, satellite signal, radio frequency or wirelessly. A device or person who transmits data is referred to as the sender, while the computer that receives the data is known as the receiver. In a data communications network, more than two computers could be involved in the communication process.
Multiplexing and Demultiplexing are communication techniques that optimize VDR options bandwidth use and reduce costs. Both processes require special hardware that can combine and separate signals. This function is typically performed by custom integrated circuits which are found in a wide variety of communication devices such as phones, computers, and printers.
Full-duplex is the method of data transmission that permits simultaneous two-way communication between a pair of devices. This is a more complex mode than simplex transmission since it requires the ability of sending and receiving data at the same time.
