Consider the following code fragment in C++: int *p; *p = 5; The code fragment mentioned above results in a dangling pointer being dereferenced, which could cause the program to crash.
What is a dangling pointer?
Dangling pointers are those pointers that refer to a memory location that has been freed or deleted. When a memory area is deallocated, the pointers pointing to that area become invalid, which can cause the program to crash. It's also referred to as a pointer that doesn't point to a valid object.
Dangling pointers arise in C++ when an object is deleted, but some pointer variables still refer to the memory location of the deleted object. This is a significant issue because attempting to use the pointer variable will cause the program to crash.

A RISC processor has 8 global registers and 10 register windows. Each window has 4 input registers, 8 local and 4 output. How many total registers are in this CPU
There are a total of 168 registers in this RISC processor.
To find the total number of registers in a RISC processor with 8 global registers and 10 register windows, where each window has 4 input registers, 8 local registers, and 4 output registers, we need to calculate the number of registers in each category and add them up.
Step 1: Count global registers
There are 8 global registers.
Step 2: Count registers in register windows
Each register window has 4 input, 8 local, and 4 output registers.
Total registers per window = 4 input + 8 local + 4 output = 16 registers per window.
Step 3: Calculate total registers in all register windows
There are 10 register windows.
Total registers in all windows = 10 windows × 16 registers per window = 160 registers.
Step 4: Calculate total registers in the CPU
Total registers in the CPU = global registers + registers in all windows
Total registers = 8 + 160 = 168 registers.

What an RRD in computer?
Answer: RRDtool (round-robin database tool) aims to handle time series data such as network bandwidth, temperatures or CPU load. The data is stored in a circular buffer based database, thus the system storage footprint remains constant over time.
Explanation:
A candidate key is group of answer choices a. an attribute b. a binary relationship c. a collection of one or more tuples d. a non-empty set of attributes
A candidate key refers to a non-empty set of attributes that uniquely identify tuples (rows) in a database table.
It is one of the important concepts in the relational database model for ensuring data integrity and avoiding redundancy.
In a relational database, a candidate key serves as an identifier for each record within a table. It consists of a single attribute or a set of attributes that can uniquely identify a tuple. For instance, in a table of students, a student ID attribute might be a candidate key because it is unique to each student. Multiple candidate keys can exist within a single table. From these candidate keys, one is typically selected as the primary key for the table, while others remain as alternate keys. Understanding these keys and their role in database design is crucial to effectively manage data and ensure its integrity.

T/F -Touchpads are found most often on desktop computers.
False. Touchpads are not typically found on desktop computers. While it's technically possible to attach a touchpad to a desktop computer, they are much more commonly found on laptops or notebooks.
Touchpads are a convenient way to control the movement of the cursor on a laptop or notebook, without the need for a separate mouse. They are typically located just below the keyboard and allow the user to move the cursor by sliding their finger across the surface of the touchpad.
Desktop computers, on the other hand, usually come with a separate mouse as the primary input device for controlling the cursor. While some desktop keyboards may have built-in touchpads or trackballs, these are much less common than traditional mice.
In summary, touchpads are primarily found on laptops or notebooks, while desktop computers typically rely on separate mice for cursor control.

Suppose a computer using direct mapped cache has 2³² bytes of main memory and a cache of 1024 blocks, where each block contains 32 bytes.
a How many blocks of main memory does this computer have?
b Show the format of a memory address as seen by cache; be sure to include the field names as well as their sizes.
c Given the memory address 0x00001328, to which cache block will this address map? (Give you answer in decimal.)
In a direct-mapped cache, the cache block to which a memory address maps can be determined by extracting the index field from the memory address. The index field is used to index into the cache, and it represents the cache block number.
How can we determine which cache block a memory address maps to in a direct-mapped cache?a) To calculate the number of blocks of main memory, we divide the total size of main memory by the block size. In this case, the total size of main memory is 2^32 bytes, and each block contains 32 bytes. Therefore, the number of blocks of main memory is 2^32 / 32 = 2^27 blocks.
b) The format of a memory address as seen by the cache includes the following fields:
- Tag field: The size of this field depends on the number of bits required to uniquely identify each block in the cache.
- Index field: The size of this field is determined by the number of blocks in the cache.
- Offset field: The size of this field is determined by the block size.
c) To determine which cache block the memory address 0x00001328 maps to, we need to extract the relevant fields from the memory address.
Assuming a direct-mapped cache, the index field determines the cache block. In this case, the index size is 1024 blocks, which can be represented by 10 bits. Taking the lower 10 bits of the memory address (1328 in decimal), we find that the address maps to cache block number 1328 % 1024 = 304.

Cardinality Sorting The binary cardinality of a number is the total number of 1 's it contains in its binary representation. For example, the decimal integer

Given the following traversals of a Binary Tree In Order: 22-34-41-57-65-89-10 Pre Order : 57-34-22-41-89-66-10
I. Draw the Binary Tree
II. Write the Post Order Traversal of the above tree.
The resulting binary tree is:
```
57
/ \
34 89
/ \ \
22 41 10
/
65
```
To draw the Binary Tree, we can start with the root node as 57, then we can split the In-Order traversal into two parts: the left subtree and the right subtree. We know that the first element in the Pr-Order traversal is always the root node, so we can see that 57 is the root node of the tree. Now we can split the In Order traversal into two parts: 22-34-41 and 65-89-10. The left subtree will contain 22-34-41, and the right subtree will contain 65-89-10. We can now see that the Pre Order traversal gives us the information that the left subtree starts with 34, which means that the root node of the left subtree is 34. Similarly, we can see that the right subtree starts with 89, which means that the root node of the right subtree is 89. Continuing in this way, we can fill in all the nodes of the tree.
To find the Post-Order traversal of this tree, we visit the nodes in the following order: Left subtree, Right subtree, Root node. Therefore, the Post Order traversal of the Binary Tree is: 22-41-34-65-10-89-57.
