What is the difference between a repeater and an amplifier in a computer network?
Just put out the network repeater delay, if the line over 200 meters may not have what information (the network connection is not a normal phenomenon)The amplifier can take the cable stretch extension, but also the signal amplification, the network is no longer a thing 200 meters
The two devices are used for network extension and range expansion, but the application and the principle are completely different.
Just a simple amplifier signal amplifier, the amplifier can only be advanced signal amplification, while suppressing noise and other interference, ordinary amplifiers are all amplified, may lead to decreased rate of communication or communication interruption. The amplifier usually does not manage the transmitted signal. It simply amplifies the signal, suppresses noise and interferes with it.
The repeater signal forwarding function, the equivalent of the mouthpiece, not just for forwarding data, such as advanced relay ATM asynchronous frame relay, but also for the session and application service relay transmission; wireless network, optical network is the most used network relay, and the relay is not necessarily a transmission, can also be transfer to a plurality of base stations, such as China Mobile; relay in the process involved in supporting scheduling and scheduling algorithm, and error correction algorithm, transmission efficiency algorithm;
