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.

Answer:
HVAC is stand for the heating, ventilation and the air conditioning system that basically perform various type computer management and operation system. It also helps to improve the productivity of the system.
As, HVAC system is very concerned about the security as it basically include various types of toxic chemical in the environment that include various types of criminal and terrorist activities and natural disaster.
The HVAC systems are easily cause various accidental cases due to its complexity nature. It also performing various types of function in the management sector like maintenance, system updating function an remote controlling maintenance.
Answer:
The reasons for Blue Screen Of Death are as following:-
- Faulty Memory.
- Power Supply Issue.
- Overheating of Components.
- Malfunctioning Hardwares.
- Poorly coded device drivers.
- Hardware runnign beyond it's capacity.
- Bugs in the Operating System Kernel.
These are the some of the reasons why the blue screen of death is caused.
The correct answer is C. Typeover mode
This is when you select a text and can then type over it and it automatically replaces it with what you're writing. It also creates a little box that lets you edit the selected part easily if that's what you need with things like bold or italic or change the text color.
