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.
The answer is C:
In most Franchise businesses, the franchisor provides ongoing guidance and support, and a developed way of doing business. In addition, they offer a higher rate of success as compared to start-up businesses and you may find it easier to secure finances for a franchise. You will get all the benefits that are attached with big businesses for a small business ownership.
Master data = represents critical data for important functions
Big data = represents a large volume of data for analysis
Outsourcing = uses another firms services
Archiving = stores rarely accessed important data

Answer:
4 is the correct answer for the above question.
Explanation:
- If the if-else sequence has 4 blocks then it will be designed like if, else-if, else-if and then else which made 4 blocks which are as follows:-
- The first block is an if block.
- Then the second block is an else-if block.
- The third block is also else-if block and
- The fourth block else blocks.
- So there is a need of 4 value (one value for each case) to test the application which is defined in the above scenario.
- It is because when the first if statement is false then the first else-if statement is executed and when the first else statement is false then the second else-if statement is executed and when it is false then the else statement will executed.
