Free Network Operating Systems, Architectures, and Standards Essay Sample
A network protocol is termed as a set of rules that govern the transferring of data over a given network. While a network operating system refers to a software program that controls other software and hardware, which runs on a given network.
Differences between a network operating system and a client operating system are:
A network operating system uses some remote resources while a client operating system uses only the resources on a local machine; A network operating system is designed to control, monitor and manage a given network while a client operating system is designed to control computer hardware and peripherals; A network operating system is an operating system that controls processes on the entire network while a client operating system controls processes on the individual client.

Network protocols: Overview
At a wider a variety of network communication, protocols do exist. Among them, many are defined by the standard organization and technology vendors around the globe. One of the most known protocols is the Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is the strongest and most reliable network protocols. It can be sent between available networks. Moreover, it is readily available. The IP holds a strong ground in information exchange between routers, so as the routers can select the appropriate path for network traffic. While the TCP responsibility is to ensure successful transmission of data across the network. Other critical protocols are LAN and WAN.
Basing our argument on the LAN and WAN technologies, the TCP/IP has the following description: TCP/IP is a suite of protocols which has its basis established on a four-layered model, the first layer constitute the network interface which is basically composed of LAN and WAN technologies. The second layer is made up of the IP protocol which has the task of encapsulating data into internet datagram's. On top of the IP layer there exist the transport layers which consist of two transport protocols meant to provide the actual communication. The upper most layer constitute of the application layer, where any application that is involved with a given network get access to the TCP/IP stack. (informIT.com)
Since TCP is the most widely utilized transmission protocol in the TCP/IP suite. Then it can be characterized as follows:
It should be known also that protocols can be implemented either in hardware or software or in both.
Functions of the network operating system
The network operating system (NOS) performs different functions. According to comptechdoc.org, some of the functions are as follows;
Considerations when purchasing a network operating system
When purchasing a network operating system, a company should look at the following aspects; it is important to note the size of the company, the number of users and the type of network the company wants to use. The company should also look at the ease of use of the network operating system that it wants to buy- the software should not be hard to use (this will help the company spend less on training users of the network). The chosen operating system should provide rigid security mechanisms- operating systems that are UNIX based are very good in this area. The company also should choose an operating system that is compatible with the kind or database they intend to use.
