IT, let's knock this out. 4. What is result of the following in sign-absolute notation? 01\ 110\ 100 - 01\ 001\ 100. The first bit is the sign bit (0 for positive, 1 for negative). The remaining 6 bits represent the magnitude. First number: 01\ 110\ 100 Sign: 0 (positive) Magnitude: 110\ 100_2 = 1 · 2^5 + 1 · 2^4 + 0 · 2^3 + 1 · 2^2 + 0 · 2^1 + 0 · 2^0 = 32 + 16 + 4 = 52_10 So, the first number is +52. Second number: 01\ 001\ 100 Sign: 0 (positive) Magnitude: 001\ 100_2 = 0 · 2^5 + 0 · 2^4 + 1 · 2^3 + 1 · 2^2 + 0 · 2^1 + 0 · 2^0 = 8 + 4 = 12_10 So, the second number is +12. The operation is 52 - 12 = 40. Now, convert 40_10 to 6-bit binary magnitude: 40_10 = 32 + 8 = 101000_2. Since the result is positive, the sign bit is 0. Combining the sign bit and the 6-bit magnitude: 01\ 010\ 000. Let's re-evaluate the second number's magnitude from the image. It looks like 01\ 001\ 100. Magnitude: 001\ 100_2 = 0 · 2^5 + 0 · 2^4 + 1 · 2^3 + 1 · 2^2 + 0 · 2^1 + 0 · 2^0 = 8 + 4 = 12_10. So, 52 - 12 = 40. The binary representation of 40_10 is 101000_2. In sign-magnitude notation (1 sign bit, 6 magnitude bits), this would be 01\ 010\ 000. Let's re-read the image carefully for the second number. It is 01\ 001\ 100. Magnitude: 001\ 100_2 = 12_10. So, 52 - 12 = 40. The result in sign-magnitude is 01\ 010\ 000. Checking the options: A. 00\ 101\ 000 (Magnitude 101000_2 = 40_10) B. 10\ 101\ 000 (Negative 40_10) C. 00\ 010\ 000 (Magnitude 010000_2 = 16_10) D. 10\ 011\ 000 (Negative 011000_2 = 24_10) The calculated result 01\ 010\ 000 matches option A. A. 00\ 101\ 000 5. An Example of universal gate A universal gate* is a logic gate that can implement any Boolean function without the need to use any other gate type. NAND and NOR gates are universal gates. C. NOR 6. It looks for an instruction, uses circuits to interpret it, and then carries out the instruction in a process known as the... This process describes the fundamental cycle of a CPU, which involves fetching an instruction, decoding it, and then executing it. This is known as the Machine Instruction Cycle. B. Machine Instruction Cycle 7. When the processor receives a signal, it stops what it is doing in order to attend to the request. The mechanism exploited here is: This mechanism is called interrupt handling*. An interrupt signal causes the processor to pause its current task and execute a specific routine (interrupt service routine) to handle the request. C. Interrupt handling Send me the next one 📸
