Network:

  • A network refers to a collection of two or more computer systems linked together.
  • There are different types of computer networks such as Local Area Network (LAN), Metropolitan Area Network (MAN), and Wide Area Network (WAN).
  • Networks can be categorized based on the characteristics such as topology, protocol, and architecture.
  • A computer network is also known as data network.

Explanation of Solution

b.

Bus topology:

The physical layout of devices on a network for bus topology is as follows:

  • Each PLC node is attached to the single bus trunk cable of using the cable drop.
  • The network interface module is attached using a drop cable so that each PLC can interface with the bus.
  • Each end of the bus should be terminated using a terminating resistor...
