If you were to change a system from using an Intel socket and CPU to an AMD socket and CPU, the following computer parts would generally need to be replaced:

CPU (Central Processing Unit): Since Intel and AMD use different socket designs and architectures, the existing Intel CPU would need to be replaced with a compatible AMD CPU that matches the AMD socket type.

Motherboard: The motherboard houses the CPU socket and determines its compatibility. As the CPU socket types between Intel and AMD are different, the motherboard would need to be replaced with one that supports the AMD socket type.

CPU Cooler: Depending on the specific CPU and socket change, the CPU cooler might also need to be replaced. This is because different CPU sockets often have different mounting mechanisms and thermal requirements.

RAM (Random Access Memory): In most cases, the existing RAM modules should still be compatible with the new AMD system, as long as they meet the specifications supported by the new motherboard and CPU.

Other components: Generally, other components such as storage drives, graphics cards, power supply, and peripherals should remain compatible and do not need to be replaced when switching from Intel to AMD. However, it's important to ensure compatibility with the new motherboard and CPU specifications.

It's worth noting that the specific requirements may vary based on the exact models and generations of the components involved, so it's advisable to check the compatibility of the new AMD CPU, motherboard, and other components before making any changes.

The digital counter with T flip-flops that counts in the given fashion (1, 2, 3, 5, 6, 1, 2, ...) is not self-correcting.

To design the counter, we can use three T flip-flops (A, B, C) and the following connections:

- Connect the T input of flip-flop A to its complement output.

- Connect the T input of flip-flop B to the output of flip-flop A.

- Connect the T input of flip-flop C to the XOR of the outputs of flip-flop A and flip-flop B.

This configuration ensures that the counter counts in the desired sequence: 1, 2, 3, 5, 6, 1, 2, ...

The circuit diagram for the counter is as follows:

```

       ______      ______      ______

      |      |    |      |    |      |

 -----|  A   |----|  B   |----|  C   |----

 |    |______|    |______|    |______|

 |

CLK

```

The state diagram for the counter includes the following states:

- State 1: A=0, B=0, C=0 (initial state)

- State 2: A=0, B=0, C=1

- State 3: A=0, B=1, C=0

- State 4: A=0, B=1, C=1 (unused state)

- State 5: A=1, B=0, C=0

- State 6: A=1, B=0, C=1

The counter is not self-correcting because it does not have a mechanism to detect or correct errors. If any flip-flop in the circuit experiences a glitch or error, the counter will not be able to recover and continue counting correctly.

Therefore, external measures or additional circuitry would be required to ensure error detection and correction in the counter.

Heapsort uses a priority queue to sort elements.

Heapsort is an efficient sorting algorithm that utilizes a binary heap data structure, which can be implemented as a priority queue. It involves building a heap from the input array and repeatedly extracting the maximum element (or minimum element for sorting in descending order) from the heap and placing it at the end of the sorted portion of the array. This process continues until all elements are sorted. Heapsort has a time complexity of O(n log n), making it a favorable choice for sorting large data sets. It exhibits good average-case and worst-case performance and is particularly useful when a stable sorting algorithm is not required.

When developing a program that relies on user input, it is important to consider the possibility of invalid input. Invalid input can cause your program to malfunction or even crash, so it is crucial to implement measures to prevent it.

Here's how you can check for an invalid input number and prevent it from being used in your program:

1. Define the input range: Before you begin accepting input from the user, it is important to define the acceptable range of values. For example, if your program requires a positive integer, then you should define the range as 1 to infinity.

2. Validate the input: Once you have defined the input range, you need to validate the user's input to ensure that it falls within this range. You can use a simple if statement to check whether the input is within the acceptable range. For example:

```
if input < 1:
   print("Invalid input! Please enter a positive integer.")
else:
   # input is valid, proceed with the program
```

3. Handle errors: If the user enters an invalid input, you should provide an error message and prompt them to enter a valid input. You can use a loop to keep prompting the user until they enter a valid input. For example:

```
while True:
   input = int(input("Please enter a positive integer: "))
   if input < 1:
       print("Invalid input! Please enter a positive integer.")
   else:
       # input is valid, break out of the loop and proceed with the program
       break
```

JPEG was designed to exploit the limitations of the human eye, such as the inability to perceive individual frames at faster than about 30 frames-per-second.

One of the key considerations in its design was the limitations of the human eye. One such limitation is the inability to perceive individual frames at a rate faster than approximately 30 frames-per-second, known as the persistence of vision. JPEG takes advantage of this by employing a compression algorithm that reduces the amount of data needed to represent consecutive frames, resulting in smaller file sizes.

D: Optimal Replacement suffers from Belady's anomaly.

Belady's anomaly is a phenomenon in page-replacement algorithms where increasing the number of page frames can result in more page faults. In other words, adding more memory can lead to worse performance.

Optimal Replacement (also known as MIN or OPT) is an ideal page-replacement algorithm that selects the page to evict which will be accessed furthest in the future. Belady's anomaly occurs with Optimal Replacement when the number of page frames increases, and instead of decreasing the number of page faults, the algorithm exhibits an increase in page faults.

On the other hand, the other options, a. Second-chance Replacement, b. LRU Replacement, and c. FIFO Replacement, do not suffer from Belady's anomaly.
