The OSI Layer-7 model enables reliable communication between different networks of different systems through seven hierarchical structural models. Therefore, its most basic function is to help different types of hosts transmit data. The node that completes the relay function is usually called a relay system. In the OSI Layer-7

abide by: The OSI seven layer model.OSI seven layer model, does that sound handsome? This standard was born in 1984, only 3 years earlier than I was born (accidentally exposed to their age →_→).The smart reader may have noticed that the standard is a long way behind the advent of the Internet.The reason is simple: the OSI seven-layer

LAN and WAN communications are guided by a network communication model, open Systems Interconnection (OSI). The OSI model is the product of two standardization organizations, ISO, and the American National Standards Association (ANSI).

OSI Seven layer model:The OSI (open System Interconnection) seven-layer network model, known as the Open System Interconnect Reference Model, is a logical definition, a specification that divides the network logically into 7 layers. Each layer has relevant, corresponding physical devices, such as routers, switches.

Its main function is to enable the host to send information to any network and send it to the correct target. The network layer uses IP addresses to identify network

Ha, finally to the network knowledge article. Always do not know how to write this blog, because the knowledge point is too much, the content is really not good to write Ah! But, after all, as an IT staff, do not learn network knowledge how to go out? So, to the next, before the explanation, I first come to the concept of science, what is the OSI seven layer model?The so-called seven-layer

The OSI Layer-7 model is complex due to the entire network connection process, including the interconnection between hardware, software data packets, and applications. If you want to write a program that concatenates all functions of the Internet, you must rewrite the entire program when a problem occurs in a small link. Therefore, we divide the entire network into several layers, each of which has its own
