1 Identify the basic capabilities( UNIX / Linux )  Network operating system (NOS)  provides services to clients over a network. Both the client/server and peer-to-peer networking models use network operating systems, and as such, NOSes must be able to handle typical network duties such as the following: Providing access to remote printers, managing which users are using which printers when, managing how print jobs are queued, and recognizing when devices aren't available to the network Enabling and managing access to files on remote systems, and determining who can access what—and who can't Granting access to remote applications and resources, such as the Internet, and making those resources seem like local resources to the user (the network is ideally transparent to the user) Providing routing services, including support for major networking protocols, so that the operating system knows what data to send where Monitoring the system and security, so as to provide proper securi...

TCP/IP Model  helps you to determine how a specific computer should be connected to the internet and how data should be transmitted between them. It helps you to create a virtual network when multiple computer networks are connected together. The purpose of TCP/IP model is to allow communication over large distances. TCP/IP stands for Transmission Control Protocol/ Internet Protocol. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork. TCP Characteristics: Here, are the essential characteristics of TCP/IP protocol Support for a flexible architecture Adding more system to a network is easy. In TCP/IP, the network remains ...
