- Speed: Most say cable is faster than DSL, but it doesn't always win in real-world use-Security: Different security models, but both offer adequate security that meets the needs of most users-Popularity: Cable is more popular but DSL is catching up-Customer Satisfaction: DSL customers are happier.TM is the Data Link layer protocol typically used over the DSL layer 1 connection from the CPE that's terminated at the DSLAM. After that, the DSLAM switches the data over an ATM network to an aggregation router, a layer 3 device where the subscriber's IP connection then expires.
A neural signal is another way of characterizing the electrochemical message that neurons send to each other. When a neuron receives sufficient stimulation in the form of EPSPs, voltage-gated ion channels open, and a signal is sent down the axon to the axon terminal. That is the electrical part of the message.
The neuron (nerve cell) is the fundamental unit of the nervous system. The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands. Neurons are designed to rapidly send signals across physiologically long distances. They do this using electrical signals called nerve impulses or action potentials .
