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.
On A Windows machine, you can use the netsh command.
<span>netsh interface ip set dns name="Local Area Connection" static 208.67.222.222
All the steps below means you have access to the router via Telnet or physical access and it already has a valid configuration (except the DNS)

Answer:
A lot of people have claimed that they lost their full-established accounts after using LinkedIn automation tools. LinkedIn detected the activity and blocked their accounts.
But it’s not the tool that causes spam, it’s the approach you adopt while using these tools.
Many people think that LinkedIn automation tools(LinkedCamp) can generate leads magically over the night. They send thousands of connection requests and messages using automation and as a result, LinkedIn detects their activity. This is not how it works. You need a proper strategy to leverage the potential of these tools. Even the best LinkedIn automation tools cannot guarantee success if you try to overdo the activities.
Internal Fragmentation occurs when a process needs more space than the size of allotted memory block or use less space. External Fragmentation occurs when a process is removed from the main memory. Internal Fragmentation occurs when Paging is employed. External Fragmentation occurs when Segmentation is employed.
