Ex: 101 133 Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.
Answer:
srand(time(NULL)); //using srand once
cout<< (rand()%50)+100; // first random number
cout<<endl; //new line
cout<< (rand()%50)+100; //second random number
Explanation:

One software license model allows software to be freely distributed, downloaded, and installed without paying a license fee but often requires a fee for support, training, or added functionality.Trure/false
Answer:TRUE
IT IS AN OPEN SOURCE SOFTWARE
Explanation:AN OPEN SOURCE SOFTWARE is a software which is made to accessed free of charge,no lincense is required for the use of the software. This type of softwares are usually developed to help the users which may be students or for religious purposes or for vunerable persons whom the developer feels should have access to the software. The only fee required is for maintenance or for other special features. GOOGLE'S ANDROID OPERATING SYSTEM is considered as an open source software.
It is false statement. The statement about a software licensing model allowing free distribution but potentially charging for support or additional features refers to open source software. While open source provides freedom to share and modify software, it does not guarantee that the software is free of cost. GPL-licensed open source software ensures users have the right to modify and distribute software, but may not always profit from these actions.
One software license model that permits software to be freely distributed, downloaded, and installed without a license fee but may require a fee for support, training, or added functionality is true to the open source software model. Open source software grants users the freedom to access, edit, and distribute the source code. However, open source does not necessarily mean the software is free of cost; while you can use the software without paying for it, there might be charges for additional services.
When we discuss free software, such as the software licensed under the GNU General Public License, we are referring to the freedom to share and change the software. The concept of "free" in this context is about liberty, not zero price. Developers using the GNU GPL protect your rights by allowing you to copy, distribute, and modify the software according to these terms.
It is important to note that users can change the software and they also can distribute their modified versions. However, if users distribute their modified versions, the GPL requires that these versions are also licensed under the GPL. Users are not always able to profit from selling their versions of the software, as the main idea behind this licensing is to ensure the software remains free and open for everyone's use.

Rasheed is memorizing his multiplication tables by using flash cards. He does this frequently enough that eventually he does not need the visual stimulation of the cards to remember his times tables for a test. Rasheed is then taking advantage of __________ memory
Answer:
Long-term memory
Explanation:
There are two common types of memory - Long-term and short-term.
In short-term memory, information are stored just for a very short time before they are eventually discarded or transferred to the long-term memory. It is sometimes called working memory. For example, short-time memory can be used to remember that a particular event is going to be by 12pm today. After the event, the information might either be discarded or pushed to the long-term memory.
In long-term memory, information are stored for a very long term, almost permanently. For example, long-term memory enables you to remember an event that has taken place in the past. In the case of Rasheed, he has so much learned the multiplication tables in such a way that information on the tables have been stored indefinitely in a part of his brain called hippocampus. Every time he needs the multiplication tables, they are always available. So he is already taking advantage of the long-term memory.

Computers and communication systems use _____ to represent information between computers and network systems.
Answer:
Data Code
Explanation:
In Data Communication, Data and Information are being assigned binary code in a digital system. This process is known as encoding system. This binary code helps computer of different architecture communicate with one another.
Data code is an encoding system for data in a computer. For text encoding we have ASCII, 7-bit ASCII, EBCDIC and Unicode. For non-text encoding, we have MIME, BinHex, Codec, etc. For video encoding, we have MPEG, YUV, YCbCr, chroma, e.t.c.
Computers and communication systems use **binary code** to represent information between computers and network systems. Binary code consists of two symbols, typically 0 and 1, which are used to encode data. This binary representation is fundamental for digital computing and communication, enabling the processing, storage, and transmission of information.
Computers and communication systems use **binary code** to represent information between computers and network systems. Binary code is a system of representing text or computer processor instructions using the binary number system's two binary digits, 0 and 1. This system forms the basis of all modern computing processes.
In binary code, each digit is referred to as a bit. These bits are grouped together to form bytes, typically consisting of eight bits. Bytes can represent a wide variety of data types, including characters, integers, and more complex data structures.
The primary advantage of binary code is its simplicity. Digital systems only need to distinguish between two states, which can be easily represented by electrical signals (on/off, high/low voltage). This reduces the complexity and cost of hardware.
Additionally, binary code enables reliable error detection and correction. Techniques such as parity checks and cyclic redundancy checks (CRC) ensure data integrity during transmission across networks. This binary representation is fundamental for digital computing and communication, enabling efficient processing, storage, and transmission of information across various platforms and devices.

public class factorial //defining class
{
//method fact
public static long fact(int x1) //defining method fact
{
//conditional statement
if (x1 <= 1) //if block checks parameter value less then equal to 1
{
return 1; //return value
}
else //else part
{
return (fact(x1 - 1) * (long) x1); //return factors using recursive function
}
}
//method main
public static void main(String[] args) //defining main method
{
long data=fact(5);//defining variable that holds function value
System.out.println("Factorial is: "+data); //print value
}
}
Output:
Factorial is: 120
Explanation:
In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.
If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.In else part, it uses a recursive function to calculate factorial of a number and return its value.Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.The component of the information system that is described as raw, un-processed facts, including text, numbers, images, and sounds,is called:_______.

A constructor is a method that
Select one:
A. removes the object from memory.
B. returns an object of the class.
C. never receives any arguments.
D. performs initialization or setup operations.
Answer:
A constructor is a method that performs initialization or setup operations.
Explanation:
A constructor is a special method that is immediately called just after a memory space as been allocated to an object or when an instance of the class is created.
Constructors perform initialization or setup operations, such as assigning initial values to instance Variables. They are called "constructors" because they assist in constructing an object even though they actually don't construct the object.
A constructor is a method in object-oriented programming that initializes an object's state or performs setup operations. It is defined within a class and typically has the same name as the class.
Explanation:A constructor is a special method in object-oriented programming that is used to initialize an object's state or perform setup operations when the object is created. It is typically defined within a class and has the same name as the class. Constructors can take arguments or parameters, allowing for customization and initialization of objects based on specific values.
For example, let's consider a class called 'Car' in a car dealership system. The constructor of the 'Car' class could be used to set initial values for properties such as 'make', 'model', 'year', and 'mileage' when a new 'Car' object is created.

Answer:
Option d is the correct answer to the above question.
Explanation:
Java is a programming language that gives the features to write the program in one platform and execute it on multiple platforms. The machine code is not given features like this. So for this, the java derived a class file which is then converted file of the java program which is also called the byte code. This code can be transferred on multiple machines and then excite after get converted into machine code. So to convert the byte code into machine code the java needs a JIT compiler which takes inputs as byte code and gives the output as machine code.
The above question asks that which take input as byte code then the answer is JIT which is defined as above and it is stated from option d. hence option d is the correct answer. while the other is not because--
Option 'a' states about the java compiler which gives the output as byte code.Option b states about the window system which is not the correct option.Option c states that it is the output of the interpreter but the interpreter gives the output as machine code in java language.
