The TTL field for a packet can be used to prevent its looping?
Monday, 18 December 2023 by Acácio Pereira Oliveira
The Time to Live (TTL) field in a packet is an essential component of the Internet Protocol (IP) header that plays a important role in preventing packet looping within a computer network. The TTL field is a counter that is decremented by one each time the packet traverses a network device, such as a router.

In the OSI model can all layers communicate directly with each other?
Monday, 18 December 2023 by Acácio Pereira Oliveira
In the OSI (Open Systems Interconnection) model, the layers are designed to provide a modular and hierarchical structure for network communication. Each layer has specific functions and responsibilities, and these layers work together to facilitate communication between different devices on a network. However, not all layers in the OSI model can communicate directly with each
