The Domain Name System (DNS) is a distributed database that maps domain names to their associated IP addresses. It is the way that computers locate each other on the internet. Common domain name extensions and their designated different types of services, are: .com = commercial business, .org = non-profit organizations, .net = internet services, .gov = government agencies, .edu = educational institutions, .info = informational websites, .uk = United Kingdom
- .us = United States, .co = companies, corporations, or commercial organizations, .io = input/output, typically used for tech or web services

The domain name system (DNS) is a hierarchical and decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It associates different types of information with domain names assigned to each of the participating entities. A domain name identifies the entity that owns the domain name space, which in turn directs internet traffic to the respective website or IP address.

There are various types of domain name extensions, such as Top-level domain (TLD) and Country-code top-level domain (ccTLD) that are currently available. Common domain name extensions and their services:

1. .com: Commercial businesses

2. .org: Nonprofit organizations

3. .edu: Educational institutions

4. .gov: Government agencies

5. .net: Network infrastructure

The domain name system (DNS) is essential for any network communication because the IP address of each device connected to the internet has to be unique, which could be challenging to manage. Hence, the DNS translates domain names into IP addresses so that computers can understand and locate the respective resources on the internet. It acts as the internet's directory, where computers can look up a domain name and find its associated IP address.

According to if the CDS spread for a regular 5-year CDS is 120 basis points and the recovery rate is 50%, then the CDS spread for a 5-year binary CDS on the same underlying reference entity would be 240 basis points.

However, if the recovery rate is 40%, we would need to use a different formula to calculate the probability of default per year. According to a loss of 200 basis points and a recovery rate of 40%, the implied probability of default per year conditional on no earlier default would be $0.02/(1-0.4)$, or 3.33%.

The text compression technique that uses variable-length binary strings to represent characters is known as Huffman coding.

It assigns each character a binary string, where the length of the string is determined by the frequency of the character’s use. Frequently used characters are assigned shorter codes, and less frequently used characters are assigned longer codes. This is done to reduce the amount of data that needs to be stored in memory.

Huffman coding works by first constructing a frequency table that records the number of times each character appears in a given text. Then, a Huffman tree is constructed from the table. This tree has the shortest path from the root to a character as its code. Finally, a code table is produced from the tree, which assigns each character its code.

This technique is advantageous for text compression because it allows for efficient storage of data. By assigning shorter codes to frequently used characters, fewer bits are used to store the same amount of data. This makes it easier to transfer and store files, reducing storage costs and increasing transfer speed.

Suppose we have a direct-mapped cache with 2 sets, each of size 16b.

What is the overall miss rate for the function dotprod?

answer as a percentage (including the '%' sign).In computer science, cache memory is a small-sized, high-speed memory that temporarily stores data to reduce processing time.

A direct-mapped cache is a cache memory in which each main memory block is mapped to a particular cache location. The processor performs a simple calculation to locate the position of the item in the cache.

A direct-mapped cache is a simple and efficient caching technique that saves cache meamory space and aids in speeding up cache memory processing.

The overall miss rate for the function dotprod is 25%.

Explanation: Given that, the direct-mapped cache has 2 sets, each of size 16B. Let's first calculate the number of blocks in each set. Number of blocks in each set=Size of cache / (Number of sets x Block size)= 16 B / (2 x 16 B)= 1

The number of blocks in each set is 1.

The total number of blocks in the cache=Number of sets x Number of blocks per set= 2 x 1= 2 blocks.

Let us assume that the function dotprod has four arrays, namely A, B, C, and D, each containing 32 bytes of data. Also, we assume that the arrays A and C are in block 0 and block 2 of set 0, and the arrays B and D are in block 0 and block 2 of set 1. There are a total of 8 blocks in the four arrays. Each set of the cache has only two blocks, so we can see that there will be a conflict in the placement of blocks in the cache. There is no room in the cache to store all eight blocks simultaneously.

A miss occurs when a cache is requested to locate an item in memory, but it cannot be located in the cache.

A hit occurs when a cache is requested to locate an item in memory, and it is found in the cache.

The formula for the overall miss rate is:

Overall miss rate= (Number of conflicts + Number of compulsory misses + Number of capacity misses) / Total number of referencesFor the dotprod function, the following table shows the reference patterns.

Reference Memory Block Hit/ MissBlock 0 of set 0 A HitBlock 0 of set 1 B MissBlock 2 of set 0 C HitBlock 2 of set 1 D MissBlock 0 of set 0 B MissBlock 0 of set 1 A MissBlock 2 of set 0 D MissBlock 2 of set 1 C Miss

The dotprod function has a total of 8 references.

Number of conflicts = 2

Number of compulsory misses = 0

Number of capacity misses = 2

Overall miss rate= (Number of conflicts + Number of compulsory misses + Number of capacity misses) / Total number of references

Overall miss rate= (2 + 0 + 2) / 8= 4/8= 0.5 or 50%

Therefore, the overall miss rate for the function dotprod is 50%.
