The correct answer is d. Rainbow tables use less storage space and more computational resources.

When using a rainbow table instead of brute-forcing hashes, there is a trade-off in terms of resources. A rainbow table requires less storage space as it stores precomputed values of hash chains, but it requires more computational resources to generate the table. On the other hand, brute-forcing hashes requires less computational resources as it involves trying different combinations of characters until a match is found, but it requires more storage space to store the generated hash values. Therefore, the resource trade-off between using a rainbow table and brute-forcing hashes depends on the specific scenario and the available resources.

Option C is the correct option: Rainbow tables use less computational resources and more storage space.

A rainbow table is a precomputed table of hash values for all possible plaintext inputs up to a certain length. By using a rainbow table, an attacker can quickly lookup precomputed hash values to find a matching plaintext password without having to compute each hash value from scratch. This technique is much faster than brute-forcing, which involves computing the hash value for each possible plaintext input until a match is found.

However, creating a rainbow table requires significant storage space to store all of the precomputed hash values. The size of the rainbow table grows exponentially with the length of the plaintext inputs, so it can quickly become very large for longer passwords. This means that using a rainbow table requires a large amount of storage space.

This is because a 32-bit operating system can only address a maximum of 4GB of memory. This 4GB memory limit includes all the memory on the system, including physical RAM, video memory, and any memory-mapped devices.

Even if you install more than 4GB of RAM on a 32-bit system, the operating system will not be able to access or use the extra memory. This is why it's essential to use a 64-bit version of Windows if you need to use more than 4GB of RAM. A 64-bit operating system can address a much larger amount of memory, theoretically up to 16 exabytes or 18.4 billion gigabytes of RAM.

It's worth noting that some 32-bit versions of Windows, such as Windows Server 2008, can use more than 4GB of RAM by enabling Physical Address Extension (PAE). However, PAE is not a viable solution for most desktop users, and it's much more practical to upgrade to a 64-bit operating system.

Discrete Multitone (DMT) is a multiplexing technique commonly found in Digital Subscriber Line (DSL) systems. DSL is a family of technologies designed to provide high-speed internet access over existing telephone lines. DMT is an effective method for transmitting data over these lines due to its ability to adapt to varying channel conditions and its resistance to noise and interference.

In DSL systems, DMT divides the available frequency spectrum into multiple sub-channels, each carrying a separate data stream. By using orthogonal frequencies, these sub-channels can operate independently without interference. This allows for the simultaneous transmission of data over multiple frequencies, increasing the overall data rate of the system.

DMT modulates each sub-channel using Quadrature Amplitude Modulation (QAM), which is capable of conveying multiple bits per symbol. By assigning different numbers of bits to each sub-channel based on the signal-to-noise ratio (SNR), DMT optimizes the data rate for each sub-channel. This adaptive bit loading strategy ensures efficient use of the available bandwidth while minimizing the impact of noise and interference on the transmitted signal.

The use of DMT in DSL systems allows for high-speed data transmission over long distances and varying line conditions. This has made DSL a popular choice for providing broadband internet access in residential and commercial settings. Overall, the DMT technique offers numerous advantages in terms of capacity, flexibility, and robustness, making it a vital component of modern DSL systems.
