Answer:
0xFF.
Explanation:
The Register A of HSC12 is an 8-bit register.So the maximum value for 8 bit is 8 1's (11111111). So the decimal value for the maximum 8 bits is 255 but all the options given are in hexadecimal so among the given options only 0xFF has the value of 255 in decimal F=(1111)₂.So two F's make 8 bits and their decimal value is 255.
Answer:
Option A(True) is the correct answer for the above question.
Explanation:
- The flowchart is used to give the solution of a problem through the diagram in a step by step processor. It helps the user to understand the solution easily. For diagram, it uses many types of symbols that are fixed for every sequence just like An oval symbol represents the start and end of the flowchart which is fixed for every flowchart.
- So for the decisions in a flowchart, the diamond symbol is used which is to make the decisions and it has two sides-- one is true and the other is false.
- The decisions are used also to represent the loop structure which is also called the repetition structure because the loop is controlled by the help of decisions so the diamond box is also used for the loop
- The above question-statement says that the decisions-controlled is used for the loop and for the decisions which are true because it is also described above.
