Let us consider a practical example of solid state relay as shown in the figure below. If the output switch is opened or MOSFET is off, then it is said to have infinite resistance. Similarly, if the output switch is closed or MOSFET conducts, then it is said to have a very low resist...
An Access Control List (ACL) is a packet filter that filters packets based on rules. One or more rules describe the packet matching conditions, such as the source address, destination address, and port number of packets. For packets that match the ACL rules configured on a device, the devic...

Basic structure of MOS FET relays MOS FET relay is a semiconductor relay that uses power MOS FETs in output elements. MOS FET relay consists of the following three components: 1. LED ( light-emitting diode ) chip 2. PDA ( photodiode array ) chip ...
Before the emergence of OSPF, the Routing Information Protocol (RIP) was the most widely used IGP. RIP is a distance-vector routing protocol which is gradually being replaced by OSPF, due to the former's slow convergence, tendency to form routing loops, and poor scalability. ...
A relay is an electrically operated or electromechanical switch composed of an electromagnet, an armature, a spring and a set of electrical contacts. The electromagnetic switch is operated by a small electric current that turns a larger current on or off by either releasing or retracting the armat...
