If MARIE has 4K words of main memory, addresses must have 12 bits because each bit can represent two states (0 or 1), and 2^12 equals 4096, which is the same as 4K (4 x 1024). Therefore, 12 bits are needed to uniquely represent all 4096 memory locations in the 4K words of main memory.

In order to access each of these words, we need a unique address for each one. Since each address must be unique and there are 4,000 words in the memory, we need at least 12 bits to represent all possible addresses. This is because 2^12 = 4,096, which is greater than 4,000. Therefore, addresses must have 12 bits to be able to access all of the words in the 4K memory.
In terms of how many words can be stored in the memory with 12-bit addresses, we can use the formula 2^n where n is the number of bits. So, 2^12 = 4,096 words can be stored in the memory with 12-bit addresses. If we want to answer how many words can be accessed by a specific 12-bit address, the answer would be 100 words. This is because each address represents a unique location in memory, and since there are 4,096 possible addresses with 12 bits, each address would represent 100 words (4,096/100 = 40.96, which we can round down to 40 since we can't have a fraction of a word).

The strlen function is a built-in function in C and C++ that returns the length of a C-string. It takes a C-string as input and counts the number of characters in it until it reaches the terminating null character (\0).

When the answer is TRUE.

The function does not count the null character itself, but it is included in the length of the string. Therefore, when the function returns the length of a C-string, it adds one to account for the null character.

For example, if we have a C-string "hello" which has five characters, the strlen function will return 5. However, if we add a null character at the end of the string to make it a proper C-string, like this: "hello\0", the strlen function will return 6. This is because it counts the five characters of the string and adds one for the null character.

In summary, the strlen function is a useful function in C and C++ for determining the length of a C-string. It returns the length of the string and includes the terminating null character in its count.

When the answer is FALSE.

The `strlen` function returns the length of a given C-string, but it does not add one for the null character `\0`. The `strlen` function is used to determine the number of characters in a C-string, excluding the null character, which marks the end of the string. Here's a brief explanation:

1. `strlen` is a standard library function in C/C++ programming languages.
2. This function takes a C-string (a null-terminated character array) as its argument.
3. It iterates through the C-string, counting the number of characters until it encounters the null character `\0`.
4. The function returns the number of characters found, excluding the null character.

Keep in mind that the length returned by `strlen` does not account for the null character. If you want to include the null character in the length, you should manually add one to the result.

Example:

```c
#include
#include

int main() {
 char myString[] = "Hello, world!";
 size_t length = strlen(myString);
 printf("Length of the string: %zu\n", length); // Output: Length of the string: 13
 return 0;
}
```

In this example, `strlen` returns 13, which is the length of "Hello, world!" without counting the null character.

The city government's least effective activity in reducing the digital divide would be to solely provide computers or internet access without also addressing the underlying issues that prevent certain groups from accessing technology, such as affordability, digital literacy, or language barriers. Simply providing equipment without also addressing these issues will not create long-term solutions and could potentially widen the digital divide further.

Explanation:

The digital divide refers to the gap or disparity between those who have access to digital technologies, such as computers and the internet, and those who do not. In order to bridge this gap and reduce the digital divide, city governments and other organizations often implement various policies and initiatives to increase access and affordability of computing and internet resources. However, implementing policies or initiatives that further increase the cost or affordability barriers for internet access or computing devices would be counterproductive and least likely to be effective in reducing the digital divide.

For example, if a city government were to impose additional taxes or fees on internet service providers, which could lead to increased costs for internet service, it could further hinder access for low-income or marginalized communities who already face affordability challenges. Similarly, if policies or initiatives are implemented that increase the cost of computing devices, such as computers or tablets, it could create additional financial barriers for certain groups, exacerbating the digital divide.

Efforts to reduce the digital divide should focus on increasing access and affordability of computing and internet resources, such as providing subsidies or discounts for internet service, offering affordable or subsidized computing devices, and providing digital literacy programs and training for underserved communities. Implementing policies or initiatives that further increase costs or affordability barriers would likely hinder the goal of reducing the digital divide and may not be effective in addressing the issue.

Option B, disabling the SSID broadcast, will have the least impact on improving the security of the network.

Although it may provide some level of obscurity by not broadcasting the network name or presence, this is a relatively weak security measure as it can be easily circumvented by attackers who know the network is there or who use tools to detect hidden networks.

On the other hand, enabling MAC filtering, configuring WPA2, and changing the default username and password are all significant security measures that can greatly improve the security of the wireless network. Enabling MAC filtering allows the router to only allow connections from devices with pre-approved MAC addresses, which can significantly limit unauthorized access. Configuring WPA2 provides strong encryption for the wireless network, making it difficult for unauthorized users to intercept or decode wireless communications. Changing the default username and password makes it more difficult for attackers to gain access to the router's configuration settings.

The layer that manages the transmission of data across a physical link and is primarily concerned with physical addressing and the ordered delivery of frames is the Data Link Layer.

The Data Link Layer is the second layer of the OSI (Open Systems Interconnection) model, which is a conceptual framework for understanding the functions of a communication system. The Data Link Layer is responsible for establishing and maintaining a reliable link between two nodes in a network.

The Data Link Layer is concerned with two main functions:

Framing: The Data Link Layer takes the packets from the Network Layer and divides them into smaller, more manageable units called frames.

Each frame is then given a unique physical address, known as a MAC (Media Access Control) address. The MAC address is used to identify the source and destination of the frame.

Error Control: The Data Link Layer ensures that the frames are transmitted without errors by providing error detection and correction mechanisms.

If an error is detected, the Data Link Layer requests the retransmission of the frame.

The Data Link Layer also provides flow control, which is the process of regulating the rate of data transmission to prevent the receiver from being overwhelmed with too much data.

This is accomplished using techniques such as buffering and congestion control.

Overall, the Data Link Layer plays a crucial role in ensuring the reliable transmission of data across a physical link in a network.

Base-class data members should be accessed using the scope resolution operator "::" or using the "using" keyword in the derived class.

In object-oriented programming, a derived class is a class that inherits properties and behavior from its base or parent class.

One way to reference base-class data members is by using the scope resolution operator "::" followed by the name of the data member.

This syntax allows the derived class to access the data member of the base class directly.

Alternatively, the "using" keyword can be used in the derived class to bring the base-class data members into the derived class's scope.

This approach allows the derived class to reference the base-class data members as if they were defined within the derived class itself.
