Requirements When selecting the operating system
To a LAN network, the organization needs to have information on certain topics, which may influence directly or indirectly in the successful implementation of the NOS the network. Some of these requirements are: professional staff, knowledge of costs of each NOS, hardware requirements and interoperability of systems installed with similar inside and outside the organization. Professionalization of staff When installing a local area network, one of the things that matter most to the organization, who will take over the management and maintenance of the network. Perhaps there is already a network and trained personnel to handle the current NOS, but it is the first time you install a LAN, it will upgrade the NOS, or will change the current system by a completely different is then required to invest in hiring new staff or train that is already in the company, as each NOS has its own degree of difficulty. We all know that Microsoft operating systems such as Windows for Workgroups, Windows 95 and Windows NT, have the characteristic of being easy to use and learning. The Windows GUI is almost identical in all systems, which facilitates the adaptation of a person who has always worked on Windows and now must be networked.
Generally, a person who has used both Windows 3.1 and Windows 95 for single-user tasks effectively, is able to manage with a bit of advice, one-to-peer network based on WFW or Windows 95. To manage a Windows NT network, you need a little more knowledge on what corresponds to networks, but the training is not as strong as in other systems. NetWare NOS is the most widely used, so most people involved with network management is aware of its operation. For someone who is just beginning, can be somewhat complicated to empathize with NetWare in the first instance, and must undergo training. NetWare version is installed on most medium and large businesses, universities and institutions of all kinds, is the version 3.x. The update to version 4.x is underway in most of them and should be taken into consideration that 4.x includes powerful new features in its operation, such as NDS, which can cause some headaches poorly trained staff on NetWare . It usually requires a network administrator full time. No doubt when they hear the word complexity in networks, immediately comes to mind of many professionals the UNIX system. This thought about that not everyone can use this system, there is some truth and a lot of myth.
Originally, UNIX was not created with simplicity in mind for the user operation, but the need to address several limitations that had other commercial operating systems. It is true that if you want to install a network based on the UNIX system, you must have personnel trained for such work, since they may present problems for those without prior knowledge, to venture with a network of this type. There are many enthusiastic challenges motivate them and work with UNIX can be, but when you have the right staff to manage this kind of network, the results can be surprising. After seeing these cases, the best thing for an organization that wants to reduce costs is to use the staff you already have, enabling NOS in the management of choice, but considering that it may take some time and some mistakes at the beginning , until you have enough experience. If you are looking for efficiency from the NOS is installed, then the hiring of experienced staff is the most viable alternative, except that usually these people apply for relatively high wages. NOS Costs When starting a project, the economic factor plays a key role in the decision to take, and the selection of a NOS is no exception. The cost varies between each NOS, starting from fairly high price to free distribution systems. The pay more for a NOS does not mean it will be more productive for the organization than a low cost, so we must seek that which meets the expectations of the company, trying, of course, that the payment is always the small as possible. Then it presents recent information on the costs of various NOS analyzed in this work.
Windows NT 4.0 (Microsoft) 5 users = $ 809 USD 10 users = $ 1.129 USD 50 users = $ 4.799 USD
NetWare 4.11 (Novell) 5 users = $ users = $ 1.095 $ 2.095 10 $ 50 = $ 4.995 USD users NetWare 5 ( Novell) 5 users = $ 1.195 USD 10 users = $ 2.190 USD 50 users = $ 5.320 USD
Linux Free or $ 49.95 USD (CD-ROM). Unrestricted licenses. Macintosh (Apple) Update the system 8.5, UnixWare $ 99 (Santa Cruz Operation, SCO) $ 69 USD per unit
LANtastic (Artisoft) 1 user = $ 119 USD 10 users = $ 499 USD X users = $ 999 USD
LAN Server ( IBM) 1st server = $ 795 USD Each additional license = $ 715 USD
Hardware Requirements
Each network operating system has different hardware requirements to run correctly, if they are not satisfied, the system may not operate or work at a level well lower than expected, causing serious problems in the network. It should then meet the requirements of each NOS to see if it satisfies the current team or need to invest in new hardware. Windows NT 4.0 - 33 MHz 486 processor or higher, Pentium or Pentium Pro, Intel and compatible systems, RISC processor compatible with Windows NT Server 4.0 for RISC-based systems. - 16 MB of memory. - Minimum 125 MB hard disk space Intel and compatible systems, 160 MB for RISC-based systems. - CD-ROM. - Graphics adapter VGA, SVGA or compatible with Windows NT Server 4.0. NetWare 4.11 server: - PC with 386 processor or higher. - 16 MB of RAM (more memory is required depending on number of users, which is loaded on the server, open application number and size of hard disks on the network). - A hard disk with enough free space for the size of the network. (NetWare 4.11 uses at least 55 MB of hard drive). - At least one network adapter. - Cable network. - A CD-ROM for installation. Workstations: - For each workstation must have a network adapter and a computer running the client operating system required. NetWare 5 Server: - PC with Pentium processor or higher. - 64 MB of RAM. - 1 GB hard disk. - At least one network adapter. - Cable network. - A CD-ROM for installation.Workstations: - For each workstation must have a network adapter and a computer running the client operating system required. Solaris 7 - SPARC or Intel Platform 486 (100 MHz) the Pentium. - From 600 MB to 1 GB hard disk. - Minimum 32 MB. UnixWare - Supports PCI systems, I2O, EISA, ISA, MCA Intel Pentium, Pentium Pro, Pentium II and 80486DX. - Requires floppy 3.5 "CD-ROM. - Needs 500 MB to 1GB of hard disk space. - At least 32 MB of memory. 64 MB are recommended. - SuperVGA adapter and monitor with at least 800x600. Linux - Processor Intel 386 and later, SPARC, Alpha, PowerPC, etc. - At least 4 MB of memory. - 150 to 200 MB hard disk space. VINES - PC or SMP (Super-Minicomputer Program) based on Intel. - 16 MB of memory . adapter - Ethernet, Token Ring or FDDI. LANtastic for Windows 95/98 - 486 processor or higher. - 8 MB of RAM (16 MB recommended). - 12 MB hard disk space. For Windows 3.x - 386SX processor or higher. - 4 MB of RAM. - 10 MB hard disk space. For DOS - PC XT or higher. - 640 KB of RAM. - 7 MB of hard disk space. Windows 95 - PC with 486-25 MHz or higher. - At least 8 MB of memory. - 40 to 45 MB of hard disk space. - Display VGA or higher resolution. Interoperability is the ability of different computer systems, networks, operating systems and applications to work together and share information. In an organization, computer resources are often located in departments or separate working groups, often using various network topologies and communication protocols. At higher levels, these systems often use different operating systems and applications .
It is thus necessary to integrate these systems so that everyone in the organization to communicate and share information and resources. All systems of an organization must be integrated, whether DOS-based computers, Apple Macintosh, UNIX workstations, minicomputers , or large computer systems. The network should be seen as a platform of "plug and play ', which connects multiple systems. For this you must use operating systems, applications and hardware products that support multiple networking protocols; also create a network platform underlying communication standards that allow hardware and software work together.
