With the REST architectural style, as long as each side knows what format of messages to send to the other, the code on the server side can be changed without affecting the operation of the client.
True / False
The statement is true because the REST architectural style is designed to facilitate the decoupling of client and server components, allowing them to evolve independently.
In a RESTful system, the client and server communicate using standardized methods and representations, typically over HTTP. This standardization ensures that both sides understand the format of messages to send to one another, and allows for flexibility in the design and implementation of both client and server components.
Because the client and server are decoupled, changes to the code on the server side do not necessarily affect the operation of the client, as long as the format of messages remains the same. This means that developers can modify or upgrade the server-side code without requiring corresponding changes on the client side.

What is the basic data unit (word) size for AES?
The basic data unit or word size for AES (Advanced Encryption Standard) is 128 bits or 16 bytes.
AES is a block cipher, which means that it encrypts data in fixed-size blocks, with each block consisting of 128 bits of data. This block size was selected because it is considered to be a good balance between security and efficiency.
The encryption process of AES operates on these 128-bit blocks, using a set of keys to perform a series of substitutions and permutations that transform the plaintext into ciphertext. The number of rounds that are applied to the data depends on the key size, with larger key sizes requiring more rounds to be performed.
The use of a fixed block size is a characteristic of block ciphers in general, and helps to ensure that the same level of security is maintained for all blocks of data. This makes AES a highly secure encryption standard that is widely used in various applications, including encryption of data at rest and in transit.

What sequence of keystrokes causes CSE 12 programs to terminate normally:
This sequence indicates the end of the file and will cause the program to terminate and return to the command prompt.
In order for a CSE 12 program to terminate normally, the user must input the appropriate sequence of keystrokes. This sequence is as follows:
1. First, the user must make sure that the program has finished executing all necessary code.
2. Then, the user must press the "Ctrl" and "D" keys simultaneously. This is also known as the "End of File" (EOF) character.
3. When the EOF character is input, the program will terminate and return to the command prompt.
It is crucial to understand the requirements and structure of the program in order to terminate it normally, without causing any unintended consequences or data loss.
Remember, always refer to the specific instructions provided in your CSE 12 course or assignment, as they may offer more detailed information on how to terminate programs for that particular scenario.
It is important to note that if the program is stuck in an infinite loop or is experiencing an error, this sequence of keystrokes may not work. In this case, the user may need to force the program to terminate by using a different sequence of keystrokes, such as "Ctrl" and "C".
In summary,
The sequence of keystrokes that causes CSE 12 programs to terminate normally is "Ctrl" + "D".

Routers using __ ___ protocols use a more sophisticated approach to finding the best path to a network (as compared to distance-vector protocol)
Routers using Link-state protocols use a more sophisticated approach to finding the best path to a network (as compared to distance-vector protocol).
Link-state protocols, such as Open Shortest Path First (OSPF) and Intermediate System-to-Intermediate System (IS-IS), enable routers to have a comprehensive view of the entire network topology.
This is achieved by each router in the network sharing information about its directly connected links with all other routers, thus creating a shared map of the network topology. By employing algorithms like Dijkstra's Shortest Path First (SPF) algorithm, routers can calculate the shortest and most efficient path to any destination network.
This method offers several advantages over distance-vector protocols like Routing Information Protocol (RIP). For instance, link-state protocols provide faster convergence, which reduces the time it takes for routers to update their routing tables when network changes occur. Additionally, they are less prone to routing loops and can support larger, more complex networks.

when a member function is defined outside of the class declaration, the function name must be qualified with the .
Answer: When a member function is defined outside of the class declaration, the function name must be qualified with the class name and the scope resolution operator ::. This is called the "namespace qualification" or "class qualification" syntax.
For example, if you have a class named MyClass with a member function myFunction, and you define the function outside of the class declaration, you would write:
class MyClass {
public:
void myFunction(); // declaration
};
void MyClass::myFunction() {
// definition
}
In the definition of myFunction, the function name is qualified with the class name MyClass and the scope resolution operator ::. This tells the compiler that myFunction is a member function of MyClass.
So, the correct statement is:
When a member function is defined outside of the class declaration, the function name must be qualified with the class name and the scope resolution operator ::.

num=8.0f is of what data type?
The term "num=8.0f" is an example of a declaration of a variable in programming. The "8.0f" part specifies that the variable is a floating point number with a precision of one decimal place. Therefore, the data type of this variable is a floating point number or "float" in programming terminology.
A floating point number is a numerical data type used to represent real numbers that have a fractional component. This data type is used in calculations that require a high degree of accuracy and precision, such as scientific and engineering applications.
The "f" suffix in "8.0f" indicates that the value assigned to the variable is a float. Without the "f" suffix, the value would be considered a double, which has higher precision than a float.
In summary, the data type of the variable "num=8.0f" is a float, which is a numerical data type used for high-precision calculations that require decimal places.

Which network does 10.2.100.1 belong to? A) 10.2.1.0/16 B) 10.1.0.0/16 C) It is not present
The IP address 10.2.100.1 belongs to network A, which is 10.2.1.0/16.
So, the correct answer is A.
This is because the first two octets (10.2) match with the network address of network A.
The subnet mask for network A is 255.255.0.0, which means that the first two octets represent the network address and the last two octets represent the host address.
Therefore, any IP address that starts with 10.2 is a part of network A.
Network B, which is 10.1.0.0/16, has a different first octet, so the IP address 10.2.100.1 does not belong to it.
Lastly, if an IP address is not present in either network A or B, it means that it is not a part of any defined network
