operating system and protocol software to manage the main tasks related to the network access layer. The modularization of the protocol stack enables software components in the network access layer dealing with hardware to provide interfaces for the upper layers unrelated to hardware. Network access layer and OSI model-- The physical layer in the OSI model is responsible for converting data frames into bit streams suitable for transmission media. The data link layer completes two independent ta

The TCP/IP network communication software package uses remote access commands. These commands were first developed for Arpanet by UC Berkely. It allows you to remotely register to another system and copy files from one system to another. You can obtain information about a system, such as who is currently registering for use. When calling a system address, these remote commands use the domain name or IP addr
