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:
True
Explanation:
SQL stands for structured query language , which is used to query Relational Database Management systems like SQLServer. This is not for writing applications like business layer where we use some programming languages.SQL is meant for data layer to perform CRUD operations against database.
CRUD operations :
Create
Read
Update
Delete
we can perform above operations on database by using SQL query language
Answer:
Because it helps you prove that you're you to third parties who wouldn't know otherwise. A CA helps you to establish trust with others because they're trusted for issuing valid, reliable certificates — and that trust is integral to public key infrastructure (PKI).

Answer:
applets
Explanation:
Java applets are dynamic programs that can be embedded on a webpage and run on a web browser like internet explorer,firefox or google chrome. The code for applets is developed using java programming language and facilitates interesting and complex display entities to be included as part of the web page. HTML provides a special tag called <Applet> for providing details of the applet.
