Real-World Significance of Models Flashcards
How these models apply to LANs and the Internet Importance of layers for troubleshooting
How does the TCP/IP model apply to the Internet?
The TCP/IP model is the foundation of the Internet.
It is a protocol that defines how data is sent between devices globally, making sure that different types of systems can communicate smoothly across networks.
Why are the OSI and TCP/IP models important for LANs?
Both models help standardize communication within Local Area Networks (LANs), making it easier for devices like computers and printers to share data. They ensure different devices follow the same rules to communicate.
How do the layers in the OSI and TCP/IP models help with troubleshooting network issues?
By breaking network into layer, we can identify where the problem is happening. So let’s say we have a problem with connection, we could check the physical layer (hardware) or the network layer (routing) to find the source of the problem.
Why is the TCP/IP model more commonly used in real-world networks like the Internet?
The TCP/IP model is simpler and designed specifically for real-world networking. It’s practical and focuses on how data moves across networks like the Internet, whereas the OSI model is more theoretical.
How do network models like OSI and TCP/IP help with compatibility across different devices and systems?
These models provide a standard framework that all devices follow. This ensures that even devices from different manufacturers can communicate and share data efficiently, whether in a LAN or across the Internet.
