Multiplexelési

Multiplexelési is a Hungarian term that translates to multiplexing in English. It refers to a set of techniques used in telecommunications and computer networking to combine multiple signals or data streams into a single channel. This allows for more efficient use of transmission media, such as copper wires or optical fibers, by enabling them to carry more information simultaneously.

There are several types of multiplexelési. Frequency Division Multiplexing (FDM) divides the available bandwidth of a channel into several non-overlapping frequency bands, with each signal occupying a different band. Time Division Multiplexing (TDM) divides the channel's time into discrete slots, and each signal is transmitted during its assigned time slot. Statistical Time Division Multiplexing (STDM) is a variation of TDM that allocates time slots dynamically based on the traffic demand of each signal, thus improving efficiency. Wavelength Division Multiplexing (WDM) is specifically used in optical fiber communications, where different signals are transmitted on different wavelengths of light over the same fiber.

The primary benefit of multiplexelési is increased data transmission capacity. By sharing a single communication link among multiple users or data streams, it reduces the need for separate physical connections, leading to cost savings and reduced infrastructure complexity. Multiplexelési is a fundamental concept in modern communication systems, enabling the vast amounts of data to be transmitted across the internet and other networks.
