Synapses are composed of three main parts: 1  The presynaptic ending that contains neurotransmitters. 2  The synaptic cleft between the two nerve cells. 3  The postsynaptic ending that contains receptor sites.
Link aggregation is a feature that is used to combine a number ofports together to make a single high-bandwidth data pipeline. Theswitch treats all ports in a trunk group as a single port.TheDES-3526/DES-3550 can support 2-8 ports in a trunk group.ink aggregation is a feature that is used to combine a number ofports together to make a single high-bandwidth data pipeline.

Layer 2. Datalink Layer. The second layer of the seven layers of Open Systems Interconnection (OSI) network model is called the Datalink layer. The Data Link layer resides above the Physical layer and below the Network layer. Datalink layer is responsible for providing end-to-end validity of the data being transmitted.
