Under which of the following conditions will the procedure NOT return the correct product? Select two answers.when the values of x and y are both negative when the value of x is positive and the value of y is negative
The procedure will not return the correct product in the following two conditions:
1. When the values of x and y are both negative.
2. When the value of x is positive and the value of y is negative.
The reason for this is that the procedure uses a repeat-until loop to add x to the result y number of times. However, when both x and y are negative, the loop will execute y number of times but will add -x to the result each time, resulting in the incorrect product. Similarly, when x is positive and y is negative, the loop will execute but will subtract x from the result each time, again resulting in an incorrect product.
To fix this, the procedure should include conditions to check for the signs of x and y and adjust the operation accordingly. For example, if both x and y are negative, the procedure should multiply x and y with a positive sign to get the correct product. Similarly, if x is positive and y is negative, the procedure should multiply x and y with a negative sign to get the correct product.

if a client does not have the correct dns server address specified in its tcp/ipproperties, what will occur?
When a client connects to the internet, it must have the correct DNS server address specified in its TCP/IP properties. DNS stands for Domain Name System, and it is responsible for translating domain names into IP addresses. Without the correct DNS server address, the client will not be able to access websites or other internet resources.
If a client does not have the correct DNS server address specified in its TCP/IP properties, several things can occur. First, the client may not be able to connect to any websites or internet resources. This is because the client does not know how to translate domain names into IP addresses.
Second, the client may be able to connect to some websites but not others. This is because some websites may be cached in the client's local DNS cache, while others are not. The local DNS cache is a temporary storage area where the client stores information about DNS requests it has made recently. If the requested website is not in the local DNS cache, the client will need to query the DNS server for the correct IP address. If the DNS server address is incorrect, the client will not be able to resolve the domain name.
Third, the client may experience slow internet speeds or intermittent connectivity issues. This is because the client will be constantly trying to resolve domain names, but without the correct DNS server address, it will not be able to do so effectively.
In conclusion, having the correct DNS server address specified in a client's TCP/IP properties is crucial for accessing websites and other internet resources. Without the correct DNS server address, the client may experience connectivity issues, slow internet speeds, or an inability to access certain websites.

2. An explicit deny does not override all allows.
3. All policies are evaluated before a request is allowed or denied.
Explanation:
1. This means that if there is an explicit allow policy for a resource, the user or entity will be granted access to that resource even if there is a default implicit denial of access to all resources. However, if there is an explicit deny policy for that same resource, the user or entity will be denied access to it.
2. This means that even if there is an explicit deny policy for a resource, the user or entity may still be granted access to it if there is an explicit allow policy for that same resource.
3. This means that all policies are checked before a request is either allowed or denied. This includes the policy attached to the user, group, or role, as well as any policies attached to the resource being accessed.

gateway cities are thus named because of their function as centers of computer and technology production. group of answer choices true false
The statement is false because gateway cities are not named for their function as centers of computer and technology production, but rather for their role as transportation hubs or gateways to other regions.
Gateway cities are typically named for their function as transportation hubs or gateways to other regions, rather than their function as centers of computer and technology production. These cities are often located near major airports, seaports, or highways, and serve as important economic and cultural centers for the surrounding region.
While many gateway cities do have a significant technology sector or are home to major technology companies, this is not the primary reason for their designation as gateway cities. Instead, they are typically named for their role in connecting people and goods across different regions and fostering economic growth and development.

What kind of variable is accessible to other scripts?
The kind of variable that is accessible to other scripts is a public variable.
In Unity, variables defined in a script can have different access modifiers that determine their visibility and accessibility. When a variable is declared as public, it can be accessed and modified by other scripts or components in the Unity project. This allows for easy communication and sharing of data between different scripts.
By declaring a variable as public, it becomes a globally accessible variable that can be accessed and modified from other scripts by directly referencing the script component or object that contains the variable.

for a direct-mapped cache design with a 32-bit address, the following bits of the address are used to access the cache. what is the cache block size (in words)?
In a direct-mapped cache design with a 32-bit address, a portion of the address is used to index the cache. This portion is determined by the size of the cache.
For example, if the cache has 2^n blocks, then n bits of the address are used for indexing. The cache block size is determined by the number of bytes in each block. In this case, the question does not provide information on the number of bytes in a block, so it is impossible to determine the cache block size in words. However, the size of the cache and the number of bits used for indexing can be used to calculate the number of blocks in the cache.
