The order of register usage for parameter passing is %rdi, %rsi, %rdx, %rcx, %r8, and %r9.

The order of register usage for parameter passing can vary depending on the calling convention used by the specific programming language or operating system. However, a common calling convention used in x86-64 systems is the System V AMD64 ABI. In this calling convention, the registers used for parameter passing in order are:

Beyond the sixth parameter, additional parameters are typically passed on the stack. The stack pointer register (%rsp) is used to manage the stack, and the instruction pointer register (%rip) holds the address of the next instruction.

It's important to note that this is just one example of a calling convention, and different systems may use different registers or conventions. Developers should consult the documentation or specifications of their specific programming language or operating system to determine the correct register usage for parameter passing.

Certainly! Here's the Python code for the `average` function that handles non-numerical arguments using exception handling:

```python

def average(num1, num2):

   try:

       result = (num1 + num2) / 2

       return result

   except TypeError:

       print("Non-numerical arguments. Cannot compute the average!")

```

In this code, we use a `try-except` block to handle the `TypeError` that would occur if at least one of the arguments `num1` and `num2` is not a numerical value. Within the `try` block, we calculate the average by adding the two numbers and dividing the sum by 2. If no exception occurs, the result is returned.

If a `TypeError` is raised, the code will jump to the `except` block, where the error message "Non-numerical arguments. Cannot compute the average!" will be printed to the console.

You can call the `average` function with two numerical arguments to calculate the average, like this:

```python

result = average(10, 20)

print(result)  # Output: 15.0

```

And if you provide non-numerical arguments, you will see the error message:

```python

average("abc", 20)  # Output: Non-numerical arguments. Cannot compute the average!

```

This implementation ensures that the program gracefully handles non-numerical arguments without crashing and provides an informative message to the user.

Carl Woese, a microbiologist, is well-known for his contributions to the biological classification system. He is credited with establishing the three-domain system for categorizing living organisms, which is based on the phylogenetic relationships among them.

The three domains are Archaea, Bacteria, and Eukarya.Woese's contributions to the three-domain system for classification:Prior to Woese's work, the biological classification system divided all living organisms into two categories: prokaryotes (bacteria) and eukaryotes (animals, plants, fungi).However, Woese's research demonstrated that this classification system was flawed. Woese discovered that there are significant differences between bacteria and archaea, despite the fact that they are both classified as prokaryotes. He observed that they have different cell wall structures, DNA sequences, and metabolic pathways. This led him to suggest a new classification system with three domains: Archaea, Bacteria, and Eukarya.Archaea and Bacteria are both single-celled organisms that lack nuclei and other membrane-bound organelles. They are classified as prokaryotes. The main difference between them is that archaea have a different cell wall structure and membrane composition. They are also known for their ability to thrive in extreme environments.

Eukarya, on the other hand, are more complex than Archaea and Bacteria. They are multicellular organisms that have nuclei and membrane-bound organelles. Animals, plants, and fungi are all part of the Eukarya domain.In conclusion, Carl Woese's contributions to establishing the three-domain system for categorizing living organisms are significant because they have led to a more accurate and comprehensive understanding of the relationships among different organisms. The three domains reflect the evolutionary relationships among different organisms, and they provide a framework for future research in microbiology and related fields.

Winnie, by continuing to use the laptop well after reaching the age of majority, has impliedly ratified the contract.

In this scenario, Winnie took possession of the laptop as a minor and continued to use it after reaching the age of majority. The question asks whether Winnie has expressly ratified the contract, impliedly ratified the contract, disaffirmed the contract, or none of the choices.

Express ratification occurs when a person explicitly states their intention to be bound by the terms of the contract. Implied ratification, on the other hand, occurs when a person's actions indicate their acceptance and affirmation of the contract. Disaffirmance refers to the act of rejecting or voiding the contract.

In Winnie's case, since she continued to use the laptop well after reaching the age of majority, it can be inferred that she has either expressly or impliedly ratified the contract. By using the laptop, she is demonstrating her acceptance and affirmation of the contract. Therefore, the correct answer is b. impliedly ratified the contract.

The correct answer is c. disaffirmed the contract.

When Winnie, as a minor, initially took possession of the laptop, she entered into a contract with Vijay. However, as a minor, she has the legal right to disaffirm or void the contract. Disaffirming a contract means that the minor chooses not to be bound by its terms and seeks to undo the legal obligations that arise from the contract.

In this scenario, Winnie continues to use the laptop well after reaching the age of majority. By doing so, she is implying her intention to disaffirm the contract. Implied ratification occurs when a person, upon reaching the age of majority, continues to perform under a contract made while they were a minor. In this case, Winnie's actions indicate that she does not wish to ratify or affirm the contract.

Express ratification, on the other hand, would occur if Winnie explicitly stated or signed a document indicating her intention to be bound by the contract after reaching the age of majority. However, there is no mention of such express ratification in the given scenario.

Therefore, the most appropriate option is c. disaffirmed the contract, as Winnie, upon reaching the age of majority, continues to use the laptop without explicitly ratifying the contract.

The cache block size, in the context of a four-way set associative cache design with a 32-bit address that uses offset bits 4-0, is 2^5 = 32 bytes.

This means each block has 8 words (assuming a word is 4 bytes). This size is crucial for efficient data access and transfer.

Further, the offset is used to determine the exact location within a block where the desired data is. As the offset is 5 bits (from 4-0), we know that each block in the cache contains 32 (2^5) bytes of data. Since a word is typically 4 bytes, it means each cache block would contain 8 words. The ratio of total bits required for the cache implementation over the data storage bits depends on factors such as the tag storage, overheads for maintaining information, and the actual data storage.

The principle of work for stack memory is Last-In, First-Out (LIFO). This means that the most recently added item to the stack is the first one to be removed.

When an element is pushed onto the stack, it gets placed on top of the existing elements. When an element is popped from the stack, the topmost element is removed, and the stack shrinks.

In a stack memory, elements are added or removed from only one end, which is referred to as the top of the stack. The push operation is used to add an element to the top of the stack, while the pop operation is used to remove an element from the top of the stack. The LIFO principle ensures that the last element pushed onto the stack is the first one to be popped off.

Imagine a stack of plates where new plates are placed on top and the topmost plate is the one that can be easily accessed and removed. Similarly, in a stack memory, the most recent element pushed onto the stack becomes the top element, and any subsequent pop operation will remove that top element.

This LIFO behavior of stack memory makes it useful in various applications such as managing function calls and recursion in programming, undo/redo operations, and maintaining expression evaluations. It allows efficient storage and retrieval of data, with the most recently added items being readily accessible.

194.12.5.0/28Answer: Address Class: In the given network address, the first octet falls between 192 and 223, hence the address class of the given network address is Class C. Default subnet mask: By default, Class C Is IP address has a subnet mask of 255.255.255.0.

Hence, the default subnet mask for the given network address is 255.255.255.240. Custom subnet mask: As per the given network address, it is a Class C network address with a subnet mask of /28. Hence, the custom subnet mask for the given network address is 255.255.255.240. Total number of subnets: Since the subnet mask is /28, 4 bits are used for subnetting. Hence, the total number of subnets = 2^4 = 16 subnets.

Total number of host addresses: Since 4 bits are used for subnetting, 28 - 4 = 24 bits are left for host addressing. Hence, the total number of host addresses = 2^24 = 16,777,216 host addresses. The number of usable addresses: Out of 16,777,216 host addresses, 2 are reserved for network ID and broadcast ID. Hence, the number of usable addresses = 16,777,216 - 2 = 16,777,214 usable addresses. A number of bits borrowed: As per the given network address, /28 subnet mask is used. Hence, 28 bits are used for subnetting. As the default subnet mask for the Class C address is /24, we borrowed 4 bits from the host portion to create 16 subnets from the given network address. Therefore, the answer is:Address class: Class CDefault subnet mask: 255.255.255.240Custom subnet mask: 255.255.255.240Total number of subnets: 16Total number of host addresses: 16,777,216Number of usable addresses: 16,777,214Number of bits borrowed: 4

To determine the values of \( m \) and \( n \) in the equation for average speed, we can express it mathematically:

Average speed = Distance traveled / Time taken

Let's assign variables to each component:

Average speed = \( v \)

Distance traveled = \( d \)

Time taken = \( t \)

The equation can be written as:

\( v = \frac{d}{t} \)

From this equation, we can see that \( m \) would be equal to 1 (coefficient of \( d \)) and \( n \) would be equal to -1 (coefficient of \( t \)).

Therefore, 826 addresses will be available for each of the 59 subnetworks.

When an ISP leases you the following network \[ 139.10 .8 .0 \text { / } 22 \] and you need to create 59 subnetworks from this single network, your new subnet mask (dotted-decimal) will be 255.255.254.0, and you will have 512 addresses per network.2.

If we divide the original network into 59 subnetworks, the size of the subnetwork will be:

Size of each subnetwork = Original Network / 2^n

where n is the number of bits borrowed.

The formula used to calculate the required number of bits is:

2^n = number of subnets

To calculate the required number of bits for the subnets, you should first determine the number of subnets required:2^6 = 64, therefore 6 bits are required to provide 64 subnets (the closest value greater than the required number of 59 subnets).

To create 59 subnets from this single network, we need to borrow 6 bits from the host portion of the address. Therefore, the new subnet mask would be /28.

The calculation is as follows:22 bits are already assigned to the network portion of the address, so 32 - 22 = 10 bits are left for the host portion. Borrowing 6 of the host bits gives us 10 - 6 = 4 bits for the subnet portion of the address.

So, the new subnet mask would be 255.255.255.240, which is equivalent to /28.Each subnet would have

2^(10-6) = 16 IP addresses, minus the network and broadcast addresses, which can't be used.

Therefore, each subnet would have 16 - 2 = 14 usable IP addresses. The total number of usable IP addresses available after subnetting is

59 subnets × 14 addresses = 826 addresses.

B)Virtual keyboards are used primarily on cell phones and tablets.

These devices typically lack physical keyboards due to their compact size and touch-based interfaces.

Instead, they utilize virtual keyboards that are displayed on the device's screen to allow users to input text and commands.

Virtual keyboards are designed to replicate the functionality of physical keyboards while maximizing the available screen space.

They consist of a visual representation of a keyboard, usually in a QWERTY layout, and can be accessed by tapping on the screen or through gestures.

The keys on virtual keyboards are typically displayed as touch-sensitive areas, and when a user taps on a key, the corresponding character is inputted.

Virtual keyboards also provide additional features such as autocorrect, predictive text, and gesture typing to enhance the typing experience.

Virtual keyboards offer several advantages for mobile devices.

Firstly, they eliminate the need for physical space dedicated to a physical keyboard, allowing for slimmer and more compact designs.

They also provide flexibility, as the layout and appearance of the keyboard can be modified to suit different languages and user preferences.
