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.
Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. 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:
The srand function in C++ seeds the rand function. It means that the srand function provides rand function with a number which is used by the random function to generate random numbers.
_______ is a process that insures that operations meet data validity standards. For instance, information systems that process checking accounts will only allow unique check numbers for each transaction—and reject duplicates.

int ans = 10;
int x = 65;
int y = 55;
if (x >= y)
ans = x + y;
A) 10
B) 120
C) 100
D) No value, there is a syntax error.
Answer:
Option B 120
Explanation:
There are three variables, ans, x and y given in the code. In beginning, the variable. ans, holds value of 10. And variable x and y hold value of 65 and 55, respectively. Since the value held by x is bigger than one held by y, the if condition is met and the statement ans = x + y will run. The execution of this statement will total x with y -> 65 + 55 and the initial value of ans is overwritten by the addition result which is 120.
Answer:
B) 120
Explanation:
In the first three lines of the code, three variables ans, x and y have been declared and initialized;
=> ans = 10;
=> x = 65;
=> y = 55;
On the fourth line and fifth line of the code, there is an if block statement that will get executed if the value of x is greater than or equal to that of y;
i.e
if (x >= y)
ans = x + y;
And since x = 65 and y = 55, it implies that x is greater than or equal to y.
Therefore the fifth line of the code will be executed
=> ans = x + y
=> ans = 65 + 55
=> ans = 120
Note:
Though the value of variable ans was initially 10 before the execution of the if statement, its new value 120 will replace the former value.
Therefore the value of ans after the code has been executed is 120

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.

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.
