             NEED ANSWERS TO THESE QUESTIONS IN DETAIL

 

The ABC co-operation chemical processing plant uses a computer to monitor the temperature and pressure of four (4) chemical tanks as shown in the figure below. Whenever a temperature or pressure exceeds the danger limit, an internal time sensor applies a 1 to its corresponding output to the computer. If all conditions are ok, then all output are 0.

Question 1.

If the computer reads the binary string 00101000, what problems exist?

Question 2.

What problems exist if the computer is reading 55 hexadecimal?

Question 3.

What hexadecimal number is read by the computer if the temperature and pressure in both tanks D and B are high?

Question 4.

Tanks A and B are taken out of use and their sensor outputs are connected to 1’s. The computer programmer must write a program to ignore these new circuit conditions. The program must check that the value read is always less than what decimal equivalent when no problem exist

 

Question 5.

In another area of the plant, only three (3) tanks (A, B and C) have to be monitored. What octal number is read if tank B has high temperature and pressure?
