which flag in the tcp header is used in response to a received fin in order to terminate connectivity between two network devices?

Answers

The FIN flag in the TCP header is used in response to a received FIN in order to terminate connectivity between two network devices.

When a device sends out a FIN, it is essentially asking the other device to end the connection. The other device must then reply with an ACK, which indicates that it has received the FIN. After this, the device that sent out the FIN must wait for the other device to send out its own FIN, which will be followed by another ACK from the original sender. Once both devices have sent out their FINs and the original sender has received an ACK for each one, the connection is terminated.

The FIN flag is one of several flags that can be used in the TCP header. The other flags include the SYN flag, which is used to initiate a connection, and the RST flag, which is used to reset a connection. When a connection is terminated, the FIN flag is used as a signal from one device to the other that the connection should be ended. The two devices then send out an ACK in response, which marks the end of the connection.

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).

Answers

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%.

The address tables of Bridge X and Y after the communication is as follows:Bridge XBridge X Interface AddressTable1 F 2 3Y 2 3Bridge YBridge Y Interface AddressTable1 C 1D 2E 1A 2Explanation:A.

A sends a packet to CAt the beginning of the communication, Bridge X and Y address tables are all empty. So, when A sends a packet to C, Bridge X searches its address table for C’s address. Since it can't find the address, Bridge X floods the packet out of all three interfaces (1, 2, and 3). Bridge Y receives the broadcast packet on interface 1, looks at the source address of A, and updates its address table with A's address.

It then forwards the packet out of interface 2, which is connected to C. Bridge X receives the packet back from interface 2 and updates its address table with C's address and then forwards it out of interface 3 which is connected to E.B. B sends a packet to DBridge X and Y already have D's address in their address table since D has already sent packets to A. So when B sends a packet to D, Bridge X forwards it out of interface 2 which is connected to D. Bridge Y receives the packet on interface 1, looks at the source address of B, and updates its address table with B's address.

It then forwards the packet out of interface 2 which is connected to D.C. C sends a packet to ESince Bridge X already has E's address in its address table, it forwards the packet out of interface 3 which is connected to E. Bridge Y doesn't have E's address in its address table so it floods the packet out of all of its interfaces.D. E sends a packet to ABridge X has A's address in its address table, so it forwards the packet out of interface

2. Bridge Y already has A's address in its address table since it received a packet from A, so it forwards the packet out of interface 1.E. D sends a packet to ABridge X has A's address in its address table, so it forwards the packet out of interface 2. Bridge Y already has A's address in its address table since it received a packet from A, so it forwards the packet out of interface 1.

which of the following statements are valid? a constructor can return a integer a constructor can return a char a constructor cannot return anything a constructor can return a void

Answers

Out of the given statements, the following statements are valid for a constructor: a constructor cannot return anything and a constructor can return a void.

Know what is a constructor! A constructor is a method that has the same name as the class in which it is located. When an object is created, the constructor is called, which initializes the object's values.

Constructors are used to provide initial values for the object's state (the values of instance variables) and to allocate memory for the object. A constructor does not have a return type because it returns an instance of the class it belongs to. Therefore, statement (c) "a constructor cannot return anything" is valid. A return type may be defined for a method in Java, which specifies the data type that the method will return after execution. Constructors, on the other hand, never specify a return type because they always return a reference to an instance of the class. Furthermore, it is not necessary to explicitly declare constructors because Java automatically creates a default constructor if one is not specified. Since the default constructor does not have any parameters, it initializes all variables to their default values, making it possible to construct objects without having to specify any values, making statement (d) "a constructor can return a void" valid.

which text compression technique uses variable-length binary strings to represent characters, assigning frequently used characters short codes?

Answers

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.

which statement type is a loop control structure that includes a loop-control variable, a test, and an update in its statement header?

Answers

The statement type that includes a loop-control variable, a test, and an update in its statement header is a for loop. A for loop is a type of loop control structure that is used when you know how many times a set of instructions should be executed. The structure of a for loop includes an initializing statement, a loop-control variable, a test, and an update. The initializing statement sets the value of the loop-control variable. The test is a condition that is evaluated before each iteration of the loop. If the test evaluates to true, the instructions in the loop body will be executed. If the test evaluates to false, the loop will end. The update is used to modify the value of the loop-control variable after each iteration.

For example, a for loop might look like this:

for (int i = 0; i < 10; i++) {
 // instructions in loop body
}

In this example, the initializing statement is int i = 0, the loop-control variable is i, the test is i < 10, and the update is i++. The loop will execute 10 times, starting with the value 0 for i and incrementing it each time by 1.

Overall, a for loop is a loop control structure that includes a loop-control variable, a test, and an update in its statement header.

disjoint subtypes are subtypes that contain nonunique subsets of the supertype entity set. true false

Answers

Disjoint subtypes are subtypes that contain nonunique subsets of the supertype entity set. The statement is False.

Disjoint Subtypes are mutually exclusive subtypes. A superclass may not contain an entity that belongs to more than one disjoint subtype. A subtype is an entity in a database model that is based on a super-type entity. If a superclass entity type is divided into subtypes, there are two basic alternatives for selecting an instance of the superclass and presenting it as a tuple of the subtype.

When selecting tuples of a subtype, a strategy must be adopted for coping with the common information in the superclass and the information that is exclusive to the subtype. A subtype can be described as either complete or incomplete. A complete subtype contains all of the attributes in the supertype and the subtype. In contrast, an incomplete subtype has attributes that are exclusive to that subtype.

A disjoint subtype is one in which no entity can be a member of more than one subtype, whereas an overlapping subtype is one in which an entity can be a member of more than one subtype.

objects that are stored in a collection should contain implementation details of the underlying structure. group of answer choices true false

Answers

True. Objects that are stored in a collection should contain the implementation details of the underlying structure, as the structure defines how the data is organized and stored. This allows the user to access and manipulate the data stored in the collection with ease.

For example, an array is a type of collection, and its underlying structure is the array itself, which consists of elements that can be accessed and modified through indexing. An array is a data structure that stores data in an indexed, linear fashion, making it easy to manipulate and access the stored data. Similarly, a linked list is a collection, and its underlying structure is a linked list node, which consists of a data element and a reference to the next node in the list.

By understanding the underlying structure of the collection, users can easily access and manipulate the data stored in it. For example, an array can be easily traversed by looping through the indices of the array, while a linked list can be easily traversed by looping through the nodes in the list.

In conclusion, objects that are stored in a collection should contain the implementation details of the underlying structure, as it defines how the data is organized and stored, and understanding this structure makes it easier to access and manipulate the data stored in the collection.

The boolean expression is executed before each execution of the loop body in a do-while loop. The statement is true.

A do-while loop is a loop statement that performs its first iteration without verifying the loop control variable or the condition tested by the while loop. A do-while loop can be used to repeat a block of statements until a certain condition is met.

The while loop is evaluated before the loop body is executed in a while loop. If the condition is false, the loop body is never executed. A do-while loop is distinct from a while loop in that the loop body is executed at least once, and then the condition is tested. The loop body will continue to execute as long as the condition is true. In a do-while loop, the statement(s) are executed until the condition is no longer true.

The code for a do-while loop in Java is as follows:

explain the domain name system. what are some of the common domain name extensions currently available and what types of services do they designate?

Answers

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.

7.5 code practice help I do not understand how to get the 81666.6666667 as the answer for Your average award money per gold medal was. The program works except for that.

Answers

The most probable reason why the output of your program was 81666.6666667 is because you made use of "float" or "double" instead of "int"

What is a Floating Point output?

This happens when the program performs some arithmetic or mathematical operations that involve division or decimal numbers, which results in the floating-point output.

For example, if the program calculates the average of three numbers, where the numbers are 80000, 82000, and 81000, the result would be 81666.6666667.

You should make use of "int" which gives input only in whole numbers without decimals or floating point numbers.
