Network Operating Systems
NetWare de Novell
It is one of the most reliable service platforms to provide secure and
continuous network access and information resources, especially regarding file
servers. The Netware opertivo system consists of server and client
applications. It provides services such as file management (using the NDS
database), seguirdad powerful and services transparent to the user printing. It
has the disadvantage that can not interoperate with other Windows NT networks.
This network operating system is a suite of protocols designed based on
the architecture of the XNS protocol. It provides comprehensive support for
most desktop operating systems on the market, including DOS, Windows,
Macintosh, OS / 2 and Unix. Novell also supports local area networks and
asynchronous wide area communications. (Informaticamoderna.com, 2015)
The general features of a network operating system are:
· Connect
all computers and network resources.
· Central
user management.
·
Provides security, controlling access to data and resources. You must validate
access (keys, certificates, biometrics, etc.) and see implement security
policies.
·
Coordinates the network functions, even with their own team.
· Share
resources (carried out coordination and privileges when sharing). Therefore,
greatly improves the resource utilization.
· Allows
you to monitor and manage the network and its components.
LAN
Manager de Microsoft
LAN Manager is a network operating system created by Microsoft and functioning as a server application. It runs under Microsoft OS / 2 and was developed in conjunction with 3Com. The file server can be used concurrently for other tasks such as database services. In other words, the system provides a good multitasking function. It also supports most desktop operating systems such as DOS, Windows and OS / 2 clients. Currently, the LAN Manager tool has been replaced by Microsoft Windows NT Server and mostly being used in Windows NT and Windows 2000.
Since Microsoft released the first Windows NT in 1993 as network operating system, it has not stopped evolving and amplicar functions and interoperability with other operating systems such as Netware. Windows NT combines the operating system and network equipment in one system and traabaja on a domain model. It consists of Windows NT Server, which sets up a team to work as a server, and Windows NT Workstation, a computer that provides client functions. After Windows NT, Windows Server 2000 and Server 2003. (informaticamoderna.com, 2015)

LANtastic de Artisoft
LANtastic supports
a variety of PC operating systems such as Windows NT 4.0
/2000/2003 (for workstation and / or server) and Windows XP. It
has improved support for multi-platforms. The installation and
operation of the system is fast and easy to use, besides having an
improved interface that allows all PCs connected to the
network can communicate using only the Chat tool. It
is not necessary that users use a dedicated server or a network
administrator to have full-time, because the system is
simple andeasy to maintain. (Chasing, 2013)
Banyan VINES
The integrated virtual
network service Banyan (VINES Virtual Integrated Network Service or English) is
a network operating system based on a family of proprietary protocols. The
protocol is basically derived from the protocols of the systems Xerox Network
(XNS or Xerox Network Systems in English), in which a client-server
architecture that allows customers to request specific services to servers,
such as file access is used and printers. (Chasing, 2013)
UNIX
UNIX is a multitasking, multiuser
operating system, which means you can run multiple programs simultaneously, and
can manage multiple users simultaneously. It was developed at Bell Laboratories
(by Kernighan & Thompson), and although it was originally designed for the
PDP-11, a machine Digital, now runs on lots of platforms with many different
types of microprocessors, making it a multiplatform system, and thereby causing
a machine executable program code on a UNIX platform does not have to be
enforceable in another. However, all UNIX are supported at two levels. UNIX is
a network operating system and has some characteristics of distributed system,
since there is a name £ nico for all files available on the network, and is
independent of the machine, or more specifically, in this name does not include
the name of the machine where the file is stored. This is called location
transparency, and is achieved, for example, Sun NFS
It is an operating system:
§ Multitasking,
§ Multi-user,
§ Joint Planning,
§ Almost all implementations are virtual
memory.
UNIX is a multitasking, multiuser
operating system, so certain mechanisms must be established so that,
simultaneously, the user data are protected against other and they can be
shared if necessary. UNIX has a mechanism associated with each file
permissions. This mechanism allows files and directories belonging to a
particular user. UNIX also allows files to be shared between users and user
groups. The default behavior in most systems is that all users can read the
files of another user, but can not modify or delete them. (S / A, s / f)
LINUX
Linux is a Unix-like operating system designed to maximize the capabilities of PC-based computers and later i386 microprocessor. It is an OS capabilities multiprocessing, multitasking, multiuser. However, unlike other PC Unix systems, you do not have to pay heavy license for the use of Linux.
The concept that many users may access applications or processing power on a single PC was a mere dream a few years ago. Linux allows more than one person can work on the same version of the same application simultaneously from the same terminals, or in separate terminals.
Networks and telecommunications
The superiority of Linux over other operating systems is evident in their utilities for networking and communications. No other operating system includes capabilities so tightly coupled network. Linux supports the following network interfaces: Ethernet, FDDI, token ring, ARCNET, X.25, ISDN, serial synchronous and asynchronous lines.
Ethernet
With Linux you can connect to the Internet and the vast world of information that the network covers. Email, Mailing Lists, Interest Groups, Search and File Transfer, Gopher, WAIS, and of course, World Wide Web.
Linux You can connect to a local network, and make server for MS-DOS, Windows, Windows for Workgroups (WfW), Windows 95 and Macintosh at a cost well below other business systems. (Purdy, 2004)

FEDORA
Fedora is a distribution based, like Mandriva RPM and has the backing of Red Hat Fedora .. try to be the leader in the field of using free software and code abierto.Prefieren make changes in the sources that apply a specific patch for distribution, thus ensuring that updates are available for all variants of Linux.
Yum is the package manager system. An alternative to this administrator is apt-rpm (comparable with APT but manages RPM) which could be more familiar to people who have used Debian or derivatives. As Mandriva and Ubuntu, has Fedora repositories which recommends using only open source software or libre.Fedora highlighted in safety and use SELinux and other security measures. (Noti-Linux, 2008)

Ubuntu
The name of the distribution comes from the Zulu and Xhosa concept of Ubuntu means "humanity to others" or "I am because we are". Ubuntu is focused on personal computers, but it also has support for servers.
It is a derivative of Debian, so it has almost all its advantages including the use of deb packages. Stable versions are released every 6 months, although sometimes it is not recommended to upgrade immediately. The official desktop environment is Gnome although there are other versions of ubuntu with other desktops (Kubuntu (KDE) Xubuntu (XFace), etc ...). the sudo command is used to avoid using the root account.

RED HAT
Red Hat is installed with a graphical environment called Anaconda, designed for easy use by novices. It also incorporates a tool called Lokkit to configure firewall capabilities.
As in the Red Hat Linux 8.0, UTF-8 was enabled as the coding system font for the system. This has little effect on English users, but when the top of the game character is used ISO 8859-1 encoding these are radically different. This can be seen, for example, users who speak French or suecocomo something aggressive, because their old filesystems look very different and can then be unusable. You can get this change by removing the ".UTF-8" configuration of the language.
Version 8.0 was also the first to include the graphical desktop environment Bluecurve.
Red Hat Linux lacks many features due to possible copyright and patents. (Lopez, 2012)
