which statement about routers is !!!FALSE!!!
a. they (routers) put packets in the right order after they arrive at their destination
b. they are located at the intersections of the network of wires and cables that make up the internet.
c. they check the address on each packet that arrives and decide which way it should go next
Answer:
b. they are located at the intersections of the network of wires and cables that make up the internet.
Explanation:
Given that Router is a computer networking device that operates by transferring data packets between computer networks, while also ensuring traffic organizing tasks on the Internet.
Hence, Routers put packets in the right order after they arrive at their destination by matching the destination IP address of the packet and one of the addresses in the routing table.
Also, Routers check the address on each packet that arrives and decide which way it should go next by ensuring the data packets are summarized for the outgoing interface recorded in the table entry.
Therefore, the correct answer is option B

The characteristics of the first roof truss can vary depending on the specific design and construction of the truss.
But generally speaking, some common characteristics of the first roof truss include:
Triangular shape: Roof trusses are typically designed in a triangular shape to distribute weight and stress evenly. This shape allows the truss to support the weight of the roof and transfer it to the load-bearing walls.High strength-to-weight ratio: Trusses are designed to be strong yet lightweight, allowing for efficient use of materials and reduced construction costs.Wooden construction: Historically, most roof trusses were constructed using wood, due to its availability, low cost, and ease of use. Today, other materials such as steel or aluminum may be used as well.Customizable design: Roof trusses can be designed to meet specific architectural or construction needs. This allows for customization based on factors such as roof shape, building size, and desired aesthetic.Standardized construction: Trusses are typically constructed in a factory or workshop setting, with standardized designs and construction methods. This allows for efficient and consistent production, reducing construction time and cost.To learn more about roof truss visit;

The act of going from a single system to several component processes refers to: A) structuring B) balancing C) functional decomposition D) formatting
The act of going from a single system to several component processes refers to: C) functional decomposition.
Functional decomposition is the process of breaking down a complex system into smaller, more manageable parts or components, each of which performs a specific function or task. This decomposition allows for a deeper understanding of the system's inner workings and enables the development of more efficient and specialized processes.
In functional decomposition, a system is analyzed and divided into its constituent functions or processes. Each function is then examined separately, identifying its inputs, outputs, and dependencies. By breaking down the system into smaller components, it becomes easier to analyze and optimize each part individually, leading to improved overall performance and flexibility.
Functional decomposition is particularly useful when dealing with large and complex systems that can benefit from modularization and specialization. It helps to organize and structure the system in a way that facilitates easier development, maintenance, and scalability. Moreover, functional decomposition promotes reusability by creating modular components that can be easily integrated into other systems or reused across different projects.Therefore, correct option is C) functional decomposition.

when using spss for windows to compute a regression line, you should also request a __________ to see how well the data fits a straight line function.
When using SPSS for Windows to compute a regression line, you should also request a "scatterplot" or "scatterplot with regression line" to see how well the data fits a straight line function.
What is a scatterplot?A scatterplot is a graph that displays the relationship between two numerical variables. It is a two-dimensional plot with one variable plotted along the x-axis (horizontal axis) and the other variable plotted along the y-axis (vertical axis). Each point on the scatterplot represents an observation in the dataset.
A scatterplot can help you visualize the relationship between the independent and dependent variables, and the regression line can help you determine the strength and direction of the relationship. Additionally, the scatterplot can help you identify any outliers or influential data points that may be affecting the regression results.

Consider the following brute-force algorithm for solving the composite number problem: Check successive integers from 2 to [n/2] as possible divisors of n. If one of them divides n evenly, return yes (i.e the number is composite) if none of them does, return no. Why does this algorithm not put the problem in class P?
The algorithm described does not put the problem in class P.
The class P refers to the set of decision problems that can be solved in polynomial time by a deterministic Turing machine. To be in class P, an algorithm must have a polynomial time complexity.
In the given algorithm, the successive integers from 2 to [n/2] are checked as possible divisors of n. This requires iterating over a range of numbers, performing division and checking for divisibility. The time complexity of this algorithm is approximately O(n/2) or O(n), as the loop runs for about half of the input value n.
Since the time complexity of the algorithm is linear with respect to the input size, it is not a polynomial-time algorithm. In class P, algorithms must have a polynomial time complexity, typically expressed as O(n^k) for some constant k.
Therefore, the brute-force algorithm for checking composite numbers does not belong to class P because its time complexity is not polynomial.
The given brute-force algorithm for checking composite numbers does not belong to class P because it does not have a polynomial time complexity.

c. The Java memory management API allows developers to write code directly deallocating the used memory space.
d. JDK offers an interface for Java developers to use in managing the memory heap, e.g. deallocate the memory after a given period of time.
The statement about java that's true is b. A Java GC process is responsible to take care of heap memory and deallocate the space occupied by those objects no longer used. In Java, the JVM (Java Virtual Machine) handles memory management by using a process called Garbage Collection (GC).
The GC process is responsible for identifying and freeing up memory that is no longer being used by the application. This process occurs automatically and in the background, without the need for developers to explicitly create a new thread or write code to deallocate memory. The JDK (Java Development Kit) also provides an interface for developers to use in managing the heap memory, but this is not used for deallocating memory. Instead, it can be used for monitoring and tuning the performance of the GC process.
