Which of the following connects computers at different geographic locations? a-PTSN b-WAN c-SAN d-Ethernet e-LAN
Answers
WAN connects computers at different geographic locations. A wide area network (WAN) is a telecommunications network that connects devices over large geographic areas. WANs can be used to connect computers in different cities, countries, or even continents to each other.
It is used to connect different LANs, MANs, or SANs to enable data sharing and communication among them.The different types of WANs include packet switching, circuit switching, leased line networks, and satellite networks.
A WAN can be established using various technologies such as fiber optic cables, copper wires, microwave transmission, and radio waves. WAN technology can be expensive due to the high bandwidth and infrastructure needed, however, it is essential for organizations that need to connect remote offices, data centers, and cloud computing services.

on a peer-to-peer network, authentication is the responsibility of the domain
true
false
Answers
False. In a peer-to-peer network, each device is responsible for its own authentication and security. Unlike in a client-server model, there is no centralized domain controller responsible for authentication.
In a peer-to-peer network, all devices are equal and share resources, such as printers or files, without relying on a central server. This means that each device must authenticate itself to access resources shared by other devices on the network. For example, if a computer wants to access a shared folder on another computer, it must provide valid login credentials to that computer to prove its identity and gain access.
Because there is no central authority in a peer-to-peer network, each device must also be responsible for its own security. This includes setting up firewalls, installing antivirus software, and regularly updating software to protect against vulnerabilities.
Overall, a peer-to-peer network can be less secure than a client-server model since there is no centralized control and each device is responsible for its own authentication and security.

What is a class?A class can be defined as a user-defined blueprint (prototype) or template that is typically used by software programmers to create objects and define the data types, categories, and methods that should be associated with these objects.
In object-oriented programming (OOP) language, a class that is written or created to implement an interface in a software would most likely implement all of that interface's method declarations without any coding error.

SQL command statement to grant object or system privileges to users or roles. Also used to grant a role to a user.
Answers
The SQL command statement used to grant object or system privileges to users or roles and to grant a role to a user is the GRANT statement.
In SQL, the GRANT statement is used to grant object or system privileges to specific users or roles. This allows those users or roles to perform certain actions on the specified database objects, such as tables or views. The syntax for the GRANT statement varies depending on the specific database management system being used, but generally involves specifying the privileges being granted, the user or role receiving the privileges, and the object or objects the privileges are being granted on. The GRANT statement can also be used to grant a role to a user. Roles are a way to group together a set of privileges and assign them to a specific user or group of users. By granting a role to a user, that user will inherit the privileges assigned to that role.

Create a class called MathTrick in the newly created project folder.
Complete the static methods in the starter code.
Utilize Math.random() and any other methods from the Math class as needed.
Utilize .substring() where appropriate.
Each method should return a value of the correct data type.
Call the completed static methods in the main method to complete a program that does the following:
Generate a random 3-digit number so that the first and third digits differ by more than one.
Now reverse the digits to form a second number.
Subtract the smaller number from the larger one.
Now reverse the digits in the answer you got in step c and add it to that number (String methods must be used to solve).
Multiply by one million.
Subtract 733,361,573.
Hint: since replaceLtr is expecting a String, you should use String.valueOf(number) to create a String variable from the integer variable before step g.
Then, replace each of the digits in your answer, with the letter it corresponds to using the following table:
0 --> Y
1 --> M
2 --> P

For a new version of processor, suppose the capacitive load remains, how much more energy will the processor consume if we increase voltage by 20% and increase clock rate by 20%?
Answers
Answer:
The answer is below
Explanation:
The amount of power dissipated by a processor is given by the formula:
P = fCV²
Where f = clock rate, C = capacitance and V = Voltage
For the old version of processor with a clock rate of f, capacitance C and voltage of V, the power dissipated is:
P(old) = fCV²
For the new version of processor with a clock rate of 20% increase = (100% + 20%)f = 1.2f, capacitance is the same = C and voltage of 20% increase = 1.2V, the power dissipated is:
P(new) = 1.2f × C × (1.2V)² = 1.2f × C × 1.44V² =1.728fCV² = 1.728 × Power dissipated by old processor
Hence, the new processor is 1.728 times (72.8% more) the power of the old processor

Write a program that will evaluate polynomial functions of the following type:
Y = a1Xn + a2Xn-1 + a3Xn-2 + . . . an-1X2 + anX1 + a0X0 where X, the coefficients ai, and n are to be given.
This program has to be written, such that each term of the polynomial is stored in a linked list node.
You are expected to create nodes for each polynomial term and store the term information. These nodes need to be linked to each previously created node. The result is that the linked list will access in a LIFO sequence. When you display the polynomial, it will be displayed in reverse order from the keyboard entry sequence.
Make the display follow mathematical conventions and do not display terms with zero coefficients, nor powers of 1 or 0. For example the polynomial Y = 1X^0 + 0X^1 + 0X^2 + 1X^3 is not concerned with normal mathematical appearance, don’t display it like that. It is shown again as it should appear. Y = 1 + X^3
Normal polynomials should work with real number coefficients. For the sake of this program, assume that you are strictly dealing with integers and that the result of the polynomial is an integer as well. You will be provided with a special PolyNode class. The PolyNode class is very similar to the ListNode class that you learned about in chapter 33 and in class. The ListNode class is more general and works with object data members. Such a class is very practical for many different situations. For this assignment, early in your linked list learning, a class has been created strictly for working with a linked list that will store the coefficient and the degree of each term in the polynomial.

{
private int coeff; // coefficient of each term
private int degree; // degree of each term
