VHDL is a hardware description language used to model and simulate digital systems.

• VHDL stands for Very High-Speed Integrated Circuit Hardware Description Language

• It is used to describe the behavior of digital systems and circuits

• VHDL is commonly used in the design and verification of electronic systems

• It allows for simulation and synthesis of digital circuits

• Example: Writing code to describe the functionality of a dig

The 8085 microcontroller has a 40-pin dual in-line package (DIP) with specific pin configurations for various functions.

• 8085 microcontroller has a 40-pin dual in-line package (DIP)

• Pins 1-20 are for address bus, pins 21-28 are for data bus, pins 29-32 are for control signals, and pins 33-40 are for power and ground

• Pin 40 is the RESET pin, Pin 39 is the READY pin, Pin 38 is the HOLD pin, and Pin 37 is the HLDA pin

PLC is a digital computer used for automation of electromechanical processes in industries.

• PLC is used to control machinery on factory assembly lines, amusement rides, or lighting fixtures.

• It uses a programmable memory to store instructions and specific functions.

• PLCs are designed for multiple input and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impac...read more

SCADA is a system used for monitoring and controlling industrial processes.

• SCADA stands for Supervisory Control and Data Acquisition

• It is used in industries to monitor and control processes such as manufacturing, production, power generation, etc.

• SCADA systems consist of sensors, controllers, and a human-machine interface (HMI)

• Data is collected from sensors, processed by controllers, and displayed on the HMI for operat...read more
