Well I would think all of them in some way. For the first one, students need to collect data (whether it’s mathematical, scientific, etc.) to answer a question. For the second one, they may need to know how much money is in there bank account or they may need to calculate a sale to order the item. For the third one, they may need statistical data to support a position. For the last one, a student could use technological data to be able to solve their problem sorting documents.
Answer:
Explanation:
When most non-technical people hear the term “seven layers”, they either think of the popular Super Bowl bean dip or they mistakenly think about the seven layers of Hell, courtesy of Dante’s Inferno (there are nine). For IT professionals, the seven layers refer to the Open Systems Interconnection (OSI) model, a conceptual framework that describes the functions of a networking or telecommunication system.
The model uses layers to help give a visual description of what is going on with a particular networking system. This can help network managers narrow down problems (Is it a physical issue or something with the application?), as well as computer programmers (when developing an application, which other layers does it need to work with?). Tech vendors selling new products will often refer to the OSI model to help customers understand which layer their products work with or whether it works “across the stack”.
Layer 7 - Application
To further our bean dip analogy, the Application Layer is the one at the top--it’s what most users see. In the OSI model, this is the layer that is the “closest to the end user”. It receives information directly from users and displays incoming data it to the user. Oddly enough, applications themselves do not reside at the application layer. Instead the layer facilitates communication through lower layers in order to establish connections with applications at the other end. Web browsers (Google Chrome, Firefox, Safari, etc.) TelNet, and FTP, are examples of communications that rely on Layer 7.
Layer 6 - Presentation
The Presentation Layer represents the area that is independent of data representation at the application layer. In general, it represents the preparation or translation of application format to network format, or from network formatting to application format. In other words, the layer “presents” data for the application or the network. A good example of this is encryption and decryption of data for secure transmission - this happens at Layer 6.
A cryptocurrency is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.
Answer:
int calculate_cost(int quantity) {
double cost = 0;
if (quantity <= 20)
cost = quantity * 23.45;
else if (quantity >= 21 && quantity <= 100)
cost = quantity * 21.11;
else if (quantity > 100)
cost = quantity * 18.75;
return cost;
}
Explanation:
Create a function called calculate_cost that takes one parameter, quantity
Initialize the cost as 0
Check the quantity using if else structure. Depending on the quantity passed, calculate the cost. For example, if the quantity is 10, the cost will be $234.5
Return the cost
