The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with its neighbor layer on the destination. Each layer uses Protocol Data Units (PDUs) to communicate and exchange information. Protocol Data Unit (PDU) Protocol Data Units contain the control information attached to the data at each Read More

When the current flows through the conductor, the needle turns parallel to the line of induction about the conductor. The north pole points in the induction flow’s direction and how much the needle turns is based on the electrical current’s overall strength. Who Invented Read More
