A pc network need to be physically and logically made in this type of way which makes it possible with the underlying network elements to communicate with one another. This structure of a computer network is called the pc network architecture.
The fourth technology of fiber-optic interaction systems utilised optical amplification to decrease the want for repeaters and wavelength-division multiplexing (WDM) to boost information ability. The introduction of WDM was the beginning of optical networking, as WDM grew to become the technology of option for fiber-optic bandwidth growth.[24] The very first to current market using a dense WDM method was Ciena Corp.
Introduction of the Router Network units are Actual physical gadgets that allow components on a computer network to communicate and communicate with one another.
