What is Noise in Communication? A broad definition of noise in communication is something that keeps a receiver from completely comprehending a message. Distractions can inhibit a person from offering his undivided attention and may keep him from fully grasping what you are trying to say.
Difference Between FDM and FDMA. Frequency Division Multiplexing, or FDM, is a multiplexing technique for the physical layer that allows multiple low bandwidth signals to share the same high bandwidth frequency range. It is achieved by allocating a smaller frequency range to each signal that is using the same channel.
Ink vs. Toner. The biggest difference between ink and toner cartridges is in how long they last. The typical life of an inkjet cartridge might be 500 pages, depending on heavily you printed your pages. Ink cartridges can also stop working early if the heads dry out or become clogged. For that reason, it is critical to use the printer at least once every week. Toner cartridges, on the other hand, typically last for at least 2,000 pages and cartridges for large laser printers last even longer.
