2)a) Geometric representation of how the computers are connected to each other is known as topology. Computers are connected via wires (link) that varies based model (like as mesh, star, ring, bus, hybrid) and number computer. Say you have 3+X1+X2 devices. Here, X1 and X2 is the last two digits of your id. Now Predict the number of wires (link) required for the various topology. *X1 = 7 , X2 = 1
