What are the uses of flags in microprocessor?
Flags are a modified kind of register that record the condition of a microprocessor’s calculation. For instance, a “zero status” flag is activated only when the microprocessor’s calculation concludes with a “zero” status.

What is 8086 microprocessor carry flag?
Auxiliary Carry Flag (AF) is one of the six status flags in the 8086 microprocessor. This flag is used in BCD (Binary-coded Decimal) operations. The status of this flag is updated for every arithmetic or logical operation performed by ALU.
What is the difference between overflow and carry flag?
The difference between Carry and Overflow is that Carry is used for unsigned numbers whereas Overflow is used for signed numbers. Carry is detected when addition of two numbers becomes a smaller number than the input terms.
What is overflow in coding?
In computing, an overflow error can occur when a calculation is run but the computer is unable to store the answer correctly. All computers have a predefined range of values they can represent or store. Overflow errors occur when the execution of a set of instructions return a value outside of this range.
What is an overflow error example?
What this means is that a certain data type used for storing a piece of data was not large enough to hold the data. For example, if you try to fit twelve cans of soup in a box designed to hold ten cans, two cans will “overflow” that space. By the same token certain data types can only store numbers of a certain size.
What type of error is an overflow?
In computing, an overflow error is an error that happens when a program receives a number, value or variable outside the scope of its ability to handle. This type of error is somewhat common in programming, especially when dealing with integers or other numerical types of variables.
What does it mean if the overflow pipe is dripping?
When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve. Float valves are found in toilet cisterns, cold water tanks and central heating feed and expansion tanks. When the water in the tank is used, its level goes down and so does the ball and arm.
