Briefly describe how switch operates.

Expert Solution

Switch can be defined as an active intelligent device in the network which is used to connect multiple devices together. Various networked devices can communicate among each other using switch. Switches support unicast, broadcast and multicast communications. The transmitting and receiving can happen simultaneously. Switches control the data flow across a network by sending a received data packet only to the devices for which the packet is planned. Every networked device linked to a switch can be detected using the network address, which enables the switch to control the traffic flow. It maximizes the network security and efficiency.

A switch performs at the second layer of the OSI model (data link layer) in order to develop an individual collision domain for every switch port. Every device linked to a switch port can transmit data to any other ports whenever they want without any interference. Switches can also perform at the network layer of the OSI model or on higher layers. Such a switch is called multilayer switch.

Describe with detail how this molecular switch is analogous to a light switch that one person turns on and another person turns off.

1. Describe with detail how this molecular switch is analogous to a light switch that one person turns on and another person turns off. In your description indicate the molecular components in “turning on” and “turning off” the switch. 2. Describe why it is just as important for normal cell functioning to turn the switch off as it is to turn the switch on.

An inductor in a switch-mode power supply that operates at a peak current of 8 A needs to store 80 mJ of energy, thereafter release it to a 10 ? load resistor. Suppose this inductor had to be custom designed and built as a solenoid coil wound on a pencil (10 mm diameter) with no magnetic properties. Only one layer of turns is allowed on the pencil’s outer surface, and 0.1-mm diameter enamel coated wire has to be used. Answer...
