If the last operation performed on a computer with an 8-bit word wasan addition in which the two operands were 1010 and 1011, whatwould be the values of the following flags?1. Zero flag.u. Overflow flag.

What is the status of sign flag when an arithmetic operation returns a positive number? A) Sign flag set to logic 1 B) Sign flag reset to logic 0 C) Sign flag set to Z state D) None of the above

32. Format flags may be combined usingthe logical AND operator (&&)the bitwise AND operator (&)the logical OR operator (||)the bitwise OR operator (|)

For each of the following parts, determine if overflow occurs (assume values are 6-bit fixed-point binary numbers):  0011.01+0100.10 does NOT overflow  1010.10+1101.01   0111.10+0000.11 DOES overflow  1010.10+1110.00 DOES overflow  1110.10+0001.10

Which of the following statement is FALSE? A) Program counter points to the next instruction in memory B) Instruction decoder to decodes the individual instruction opcodes C) ALU unit performs the arithmetic and logical operations D) FLAG register stores the result of any arithmetic operation

3) Let R1 and R2 be two 4-bit registers that store numbers in 2's complement form. For the operation R1 + R2, which one of the following values of R1 and R2 gives an arithmetic overflow?
