Syntax, a systematic way in which words are combined and sequenced to make meaningful phrases and sentences in a given language
Syntax is a set of principles that define the order of words, clauses, and phrases to form appropriate sentences in a given language..
in other hand, Semantic is the study of meaning in language or the study of the meaning of sentences,
Pragmatics is the study of the meaning of sentences within a certain context.
so the relativity between syntax, semantic, and Pragmatic is Syntax is what we use to do our best to communicate on the most basic level (with order of words, clauses, and phrases). Semantics help determine if it makes sense. Pragmatics allows us to apply the right meaning to the right situation.

an SQL index specification that causes records with the same values on the indexed field to be stored close together is CLUSTER
In SQL, clusters are utilized to store information from several tables within the same physical storage blocks. If information from those tables is regularly searched concurrently, then is utilized. With keeping the same data blocks, the number of database block reads required to complete such searches is reduced, improving performance.
SQL clustering alludes to a grouping of two or more physical servers (nodes) connected by a LAN, which each hosts a SQL version and has access to common memory. Clustered SQL server guarantees optimum reliability as well as disaster recovery in the event that a hosting provider of the SQL Server instance malfunctions.

(a) The two main differences between ethernet and 802.11 mac protocols are
Ethernet is based on IEEE 802.3 requirements, while 802.11 mac is based on IEEE 802.11x specifications, where x is a number that represents a particular WiFi version.While 802.11 mac is a wireless network used to link close-by devices to one another and share the internet via hotspots, Ethernet is a LAN network standard used in conventional LANs.(b) A virtual carrier-sensing method called the network allocation vector (NAV) is used with wireless network protocols like IEEE 802.11 (Wi-Fi) and IEEE 802.16. (WiMax). In order to conserve power, virtual carrier-sensing is a logical abstraction that reduces the need for physical carrier-sensing at the air interface. The NAV enhances wireless channels by assisting in collision avoidance and handshaking protocol establishment.
What is the Ethernet?
Wide area networks, metropolitan area networks, and local area networks all frequently use the Ethernet family of wired computer networking technologies. Commercial use of it began in 1980, and in 1983, IEEE 802.3 was officially standardized. Ethernet is a type of network connection that is still widely used to connect devices to a network for regional networks utilized by certain businesses.

In very complex systems, the prototype can become unwieldy and difficult to manage.
a. True
b. False
The option 'a' is correct. It’s true in very complex systems, the prototype can become unwieldy and difficult to manage.
A mock-up of the solution you wish to develop is called a prototype. Without hiring a developer, you can simulate every interaction and view such that it behaves just like a finished product.
When the consumers are unsure of the precise project needs up front, the prototyping model is employed. In this model, an initial prototype of the finished product is created, tested, and constantly improved based on consumer feedback until a final acceptable prototype is reached, which serves as the foundation for creating the finished product.
The possible issue with prototypes is that they can't be properly tested in order to meet other system requirements like dependability and maintainability etc.
Although there are several problems to this strategy, the advantages of the prototype outweigh the negatives. One of the problem is that the prototype might get cumbersome and challenging to control in really complicated systems.
The management of the prototype can become complicated by any implementation and quality problems.

does it make sense to chain two different dimensionality reduction algo- rithm?
Yes, it can absolutely make sense to chain two different dimensionality reduction algorithms.
By obtaining a set of principal variables, dimensionality reduction is the process of reducing the number of random variables being considered. It can be split into two categories: feature extraction and feature selection.
You can combine two distinct algorithms, such as PCA to quickly eliminate extraneous data and LLE to work more slowly. This will probably result in the same performance but quicker outcomes.
There are frequently too many factors used in machine learning classification problems to make the final classification. These elements are essentially features, which are variables. It becomes more difficult to visualise the training set and then work on it as the number of features increases.
Sometimes, the majority of these features are redundant because they are correlated. Algorithms for dimensionality reduction are useful in this situation.

According to the opponent-process theory, there are three types of color-sensitive cones and the process of color vision begins in the cortex.
The opponent-process theory:The opponent-process theory is a theory of color vision that states that there are three types of color-sensitive cones in the retina, and that the process of color vision begins in the cortex. This theory was first proposed by Edwin H. Land in the 1960s, and has been supported by subsequent research.
One of the key pieces of evidence supporting the opponent-process theory is the finding that neurons involved in color vision are stimulated by one color's wavelength and inhibited by another's. This suggests that the brain processes color information in an opponent fashion, with different cells responding to different color contrasts.
The opponent-process theory provides a parsimonious explanation for a wide range of color phenomena, including color constancy, color after-images, and colorblindness. It has also been used to explain why certain colors are more difficult to discriminate than others, and why some colors are more salient than others.
Overall, the opponent-process theory is a robust theory of color vision that can help to explain a wide variety of color-related phenomena.
