Network Administration Essay -- Computer Science

Network AdministrationI create worked as a computer profit executive for over 5 years. I deliver worked well-nighly with cyberspaces in a mixed Microsoft Windows NT andNovell Netware environment. I am a Novell Certified Novell Engineer(CNE) and I am a certified Novell GroupWise Administrator. I havetaken classes in configuration of lake herring routers. In this essay, I willdiscuss the definition of a network administrator, the tasks andresponsibilities of a network administrator and share a day in thelife of a network administrator. For documentation on my credentials,I am including my certification certificates.What is a Network Administrator?A network administrator is one who maintains and troubleshoots yourcomputer systems. Depending on the size of your organization and thecomplexity of your engineering science, a network administrators job can rangefrom ten hours per week to large time. There are some obvious networkadministration tasks, such(prenominal) as installing or upgrading system softwareand managing substance abuser accounts and disks space, so you probably have someidea of what an administrator does. The InternationalTelecommunications league (ITU) is a consortium of telecommunicationscompanies worldwide who have, among other things, defined a serial ofrecommendations that describe how a telecommunications managementnetwork (TMN) should be operated. The ITU members have adopt a modelof management functions that I think is of interest to us because itprovides a framework that we can use to understand the role of thenetwork administrator. This function model is often referred to as theFCAPS model after the initials of each of the major functions itdescribes.TMN function Naive descriptionFault Management fastener what is broken.Configuration Management Controlling the operational parameters ofsomething so it works the federal agency you want.Accounting Management Knowing who is using how much of what, andmaybe thrill them for it.Perform ance Management Making sure it all works tolerably quickly.Security Management Controlling who can do what.The idea is that notwithstanding about any network management task can be said tobelong to one of those management functions. For example, plugging apatch-lead back in after it has fallen out is fault management,introducing a firewall onto your network is a security managementt... ...workstation can be putback in service elsewhere, the administrator would possibly format thedrives (effectively erasing all the previous data) and transplant theworkstation in a position that is less demanding than the previousone. I have found that installation of bare-assed workstations not only makesthe end user more productive, but generally the task of administeringthe workstation is easier because of the improvement in technologyi.e. newer operating system. Some administrators have found it usefulto sue a surgical procedure called ghosting to speed up the process ofsetting up triple ne w workstations. When this process, a workstationis configured with general setting sufficient for most users. Specialsoftware is used to copy an image of that configuration. When a newworkstation or workstations is needed to be configured the imaged isthen copied to the hard drive. For this procedure to work, theworkstation must have the same or very similar ironware as theoriginal workstation the image was copies from. Otherwise there willbe multiple errors and the administrator will spend time morecorrecting errors than he/she would have doing the configurationmanually.
