Option d is correct. The property of relations is that no two rows in a relation are identical.
Both reflexive and irreflexive relationships are incompatible. As a result, these two qualities are incompatible. It is not irreflexive if it is reflexive. It cannot be reflexive if it is irreflexive. However, a relationship could also be neither reflexive nor irreflexive.
The relationship between the elements of the sets is the next topic that is brought up whenever sets are being discussed. Between objects of the same set or between objects of two or more sets, relations may exist.
A directed graph can be used to depict a relation.
The number of elements in the set from which the relation has been defined equals the number of vertices in the graph. There will be a directed edge from the vertex 'x' to the vertex 'y' for any ordered pair (x, y) in the relation R. There will be a self-loop on vertex "x" if there is an ordered pair (x, x).

The AND search operator is used to search for two things at once and match both items.
What is search operator?
A character or a string of characters utilized in a search engine query to focus the search is known as a search operator (also known as a search parameter). Operators are characters and sequences of characters that express actions or cause actions to be done in computer science and mathematics. In search, boolean operators are frequently employed. For instance, the symbol AND indicates that the search results' Web pages must have both the word or phrase that comes preceding it and the word (or phrase) that comes after it. NOT denotes that the word or phrase that follows it shouldn't appear on pages in search results. Instead of pages that contain both or all of the terms in the query, the OR symbol specifies that the pages in the search engine results should include any terms on either side.

When the target file supports the same constructs and features as the source file, this process is possible. The conversion process looks for the first rule that matches the incoming data and then executes the associated action.

host a and b are directly connected with a 100 mbps link. there is one tcp connection between the two hosts, and host a is sending to host b an enormous file over this connection. host a can send its application data into its tcp socket at a rate as high as 120 mbps but host b fills up its buffer at a rate of 40mbps. on average, what is the long-term rate at which host a sends data to host b?
The long-term rate host a sends data to host b is 100 Mbps, Host A's sending rate can be at most 100 Mbps. Still, Host A sends data into the receive buffer faster than Host B can remove the data.
Transmission Control Protocol (TCP) means a standard that describes how to establish and maintain a network conversation by which applications can exchange data. TCP works with the Internet Protocol (IP), which describes how computers send packets of data to each other.
Based on the story above, the receive buffer fills up at a rate of roughly 40 Mbps. If the buffer is full, Host B signals to Host A to stop addressing data by setting RcvWindow = 0; Host A then stops addressing until it receives a TCP segment with RcvWindow > 0. Host A will start sending as a function of the RcvWindow values it receives from Host B and also thus repeatedly stop.

is fast recovery used? if it is used, indicate the instances where fast recovery is applied. if it is not used, indicate the instances where fast recovery can be applied.
Fast recovery is used in instances where data needs to be recovered quickly from a backup. Fast recovery can be used in instances where data is lost or corrupted, or in instances where the system needs to be restored to a previous state.
What is fast recovery?
Fast Recovery is now TCP's final advancement. Every time network congestion is identified, the congestion window is reduced to 1 by using solely Fast Retransmit. As a result, reaching high link utilisation again takes some time. Fast Recovery, on the other hand, solves this issue by doing away with the slow-start period. Slow-start will specifically only be used at the start of a connection and once an RTO time has expired. The lack of slow-start after receiving three duplicate ACKs is due to the fact that triple ACKs inform the transmitting side of more than just packet loss. The dup ACK informs the sending side that packet has been missed by the network since the receiving side can only generate one if it gets an out-of-order packet.

The minimum value in the current stack, 18, should be returned by the call to getMin(). We create a variable called minEle that keeps track of the stack's current lowest element.
Create a data structure called SpecialStack that supports all stack operations, including push(), pop(), isEmpty(), and isFull(), as well as the extra method getMin(), which should return the SpecialStack's bare minimum element. All of these SpecialStack operations must have an O time and space complexity (1).
The current minimum element in the stack is kept in the variable minEle that we define. How to handle the situation when the minimum element is eliminated is now the intriguing aspect. To address this, we push "2x - minEle" into the stack rather than x so that the current minimal element and its value may be used to recover the prior minimum element.
