Answer:
A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration.8086 has 16-bit flag register, and there are 9 valid flag bits.The FLAGS register is the status register in Intel x86 microprocessors that contains the current state of the processor. This register is 16 bits wide. Its successors, the EFLAGS and RFLAGS registers, are 32 bits and 64 bits wide, respectively. The wider registers retain compatibility with their smaller predecessors.
Answer:
A. 243
B. True
C. 0
Explanation:
Macro instruction is a line of coding used in computer programming. The line coding results in one or more coding in computer program and sets variable for using other statements. Macros allows to reuse code. Macro has two parts beginning and end. After the execution of statement of quiz4 x, 4 the macro x will contain 243. When the macro is invoked the statement will result in an error. When the macro codes are executed the edx will contain 0. Edx serve as a macro assembler.

Answer:
2125 ns.
Explanation:
First of all Execution Time = Number of Instructions * CPI * Clock Cycle
Number of Instructions = 1000
CPI = 0.5
Clock Cycle = 1/clock rate = 1/4GHz = 0.25 * 10-9 s
So Execution Time = 1000 * 0.5 * 0.25 * 10-9
Execution Time = 125 * 10-9 s
Execution Time = 125 ns
Now 20% of the instructions take 10 ns extra time for remote communication.
1 instruction takes 10ns
so 20% of 1000 = 200 instructions will take 200*10 = 2000ns
So Total Execution Time = 125+2000 = 2125 ns.
It performs the basic arithmetical, logical, and input/output operations of a computer
