true/false. anizing a storage cabinet, a technician discovers a box of hard drives that are incompatible with current hardware and may contain sensitive data.

SQL queries cannot directly access disk blocks in the disk without accessing buffer caches in the memory. Hence, the given statement is false.

Explanation:

When a SQL query is executed, it first checks the buffer cache in the memory to see if the required data is already there. If the data is not found in the buffer cache, then the system retrieves it from the disk and loads it into the cache. This process is done to improve performance, as accessing data from memory is faster than accessing it from the disk. The buffer cache acts as an intermediary between the SQL query and the disk, allowing for more efficient data retrieval and minimizing the need for direct disk access.

It is generally safe to change data in a query since you are only changing a temporary copy of the data and not the underlying data in the table.

However, it is important to exercise caution when making changes to the data in a query, as the changes made can impact other areas of the database. When you modify data in a query, you are essentially creating a temporary copy of the original data. The changes you make to this temporary copy will not affect the actual data in the table. This means that if something goes wrong with the changes, you can simply discard the temporary copy and start over again without any permanent damage to the data in the table.
However, it is important to keep in mind that the temporary copy is still part of the larger database system, and the changes made can have ripple effects on other areas of the database. For example, if you modify data that is referenced by other tables or queries, those objects may no longer function correctly.

The correct syntax to add methods to a custom object in JavaScript is option b:

```javascript

var objName = {

 method: function() {

   // commands

 }

};

```

In JavaScript, objects are defined using curly braces `{}` and can contain properties and methods. In this case, the method is added to the `objName` object using the `method` key. The value associated with the `method` key is an anonymous function that defines the behavior of the method. The commands to be executed are placed within the function's code block.

By using the `var` keyword, we declare a variable named `objName` and assign it the object literal that contains the `method`. This creates an instance of the custom object with the added method.

To execute the method, you would use the following syntax:

```javascript

objName.method();

```

This would call and execute the method defined within the object.

It's important to note that option a, c, and d in the provided choices contain incorrect syntax for adding methods to a custom object. The correct syntax requires using the colon `:` to associate a method name with its corresponding function definition within the object literal.

Assuming that ptr is a pointer to an int, when you add 4 to it, the address is advanced by 4 bytes in memory (Option a) and the pointer will move 4 integers forward in memory (Option e).

This is because pointer arithmetic operates based on the size of the data type the pointer points to. In most systems, an int occupies 4 bytes of memory. Adding 4 to the pointer means moving the pointer forward by 4 memory locations, where each location represents one byte. Since an int occupies 4 bytes, advancing the pointer by 4 bytes effectively moves the pointer to the next int in memory.

This operation does not modify the value of the int pointed to by ptr. It only updates the address stored in the pointer. If you want to modify the value of the int, you need to dereference the pointer using the * operator. It's important to note that pointer arithmetic should be done within the bounds of the allocated memory for proper behavior.

Incrementing a pointer beyond the allocated memory range can lead to undefined behavior and should be avoided. Hence, e and a are the correct option.

After receiving a message via TCP, the computer follows a series of steps to process the data and respond appropriately. Firstly, the computer will pass c. the IP packet to the layer 3 process, which is responsible for routing the packet to the appropriate application. Once the packet is routed, the computer will process the message according to the specifications of the receiving application.

Assuming the message has been successfully received, the computer will then send a return segment with the ACK bit set to 1 and the Acknowledgement Number set to the Sequence Number of the original segment. This is done to confirm receipt of the message and to enable further communication between the two devices. In the event that the computer is unable to process the message for any reason, it may send a segment with the RST flag to 1. This is a signal to the sender that the connection has been terminated and communication is no longer possible.

True. Agglomerative hierarchical clustering procedures are better able to handle outliers than k-means.

1. Agglomerative hierarchical clustering procedures are better able to handle outliers than k-means. [True] - Agglomerative hierarchical clustering is more robust to outliers because it builds clusters by merging them based on proximity, whereas k-means can be influenced by outliers due to the mean calculation.

2. Different runs of k-means can produce different clusterings, but agglomerative hierarchical clustering procedures will always produce the same clustering. [False] - Both k-means and agglomerative hierarchical clustering can produce different clusterings in different runs due to their random initialization or tie-breaking mechanisms.

3. When clustering a dataset using k-means, SSE (Sum of Squared Errors) is guaranteed to monotonically decrease as the number of clusters increases. [False] - Increasing the number of clusters in k-means can sometimes lead to higher SSE values as the algorithm may overfit the data.

4. For a dataset that contains a density-based notion of clusters, a measure of cohesion can show poor values on the true clusters. [True] - Density-based clustering algorithms may struggle to accurately measure cohesion in datasets with irregular cluster shapes or varying densities.

5. The SSE of the k-means clustering algorithm keeps reducing with every iteration. [True] - In each iteration of k-means, the SSE is minimized by updating the cluster centroids and reassigning points, leading to a reduction in SSE.

6. The lowest value of SSE for the k-means algorithm is obtained when k=n, the number of points in the data. [True] - When the number of clusters equals the number of points, each point becomes a separate cluster, resulting in SSE equal to 0.

7. If a cluster is split by picking one of the points as a new centroid and reassigning points to the original or new centroid, the SSE of the clustering would only decrease. [False] - Splitting a cluster can increase the SSE if the new centroid leads to a worse assignment of points, resulting in higher squared errors.

The worst-case space complexity of a Binary Search Tree (BST) is O(n), where n is the number of nodes in the tree. This occurs when the tree is either completely full or completely unbalanced, requiring the maximum amount of memory to store node pointers and data.

The worst-case space complexity of a binary search tree (BST) can be O(n) in scenarios where the tree is highly unbalanced and resembles a linked list. In such cases, each node in the tree would only have one child, and the height of the tree would be equivalent to the number of nodes in the tree. This would result in a space complexity of O(n), as the amount of memory required to store each node in the tree would increase linearly with the number of nodes in the tree. However, in balanced BSTs such as AVL trees or red-black trees, the worst-case space complexity is O(nlogn), as the height of the tree is logarithmic with respect to the number of nodes in the tree. In summary, the worst-case space complexity of a BST can vary depending on the balance of the tree, and it can range from O(n) to O(nlogn).

False, the 2's complement operation is used to represent negative numbers in binary form, but it does not change the sign of a positive number or vice versa.

The statement is false. The 2's complement operation on a signed number does not change a positive number to a negative number or vice versa. Instead, it is a method used to represent negative numbers in binary form.

In 2's complement representation, the most significant bit (MSB) is used as the sign bit. If the MSB is 0, the number is positive, and if the MSB is 1, the number is negative.

To obtain the 2's complement of a negative number, the binary representation is inverted (all bits flipped) and then 1 is added to the result.

For example, in a 4-bit system, the decimal number +3 is represented as 0011, and its 2's complement is 1101, which represents -3.
