Inmost cases, a system administrator and a network administrator areusually defined as one thing. Some organizations end up giving thesetwo jobs to one person. The work of these administrators is to ensurethat the organization has proper work flow and their communicationlines are open. Network and system administrations require a lot ofhard work and dedication. This is because companies depend completelyon these networks to perform their duties as well solving issues thatarise in the company (Clemm,2007).Their duties includes fixing network issues that have been identifiedor reported, updating the softwares and equipments, managing thestorage for data and emails, setting up as well as maintainingcompany’s computer servers. Since new technologies have beendiscovered, some administrators supervise telecommunication networksto enable employees’ access work from home. There is however adifference between network administration and system administration.Network administration involves management of network communicationswhile system administration involves management of servercommunications. However, system administration is broad in scope andnetwork administration is a branch found in system administration.
Asnoted by Clemm(2007), systemadministration is broad. A system administrator deals with computersystem operations, configuration and conservation. He guarantees thatthe resources, uptime, presentation and computer security are in handwith the users requirements at the same time ensuring that it doesnot go off the budget limit. He ensures this by keeping himselfupdated on software, schooling employees, ensuring security policiesare in place, supervising employees. In large companies, systemadministration can be dived into sections such as databaseadministrators, security administrators, network administrators andweb administrators. The work of a data administrator is to sustain adatabase system. He should also ensure that the data received hasintegrity and ensure the efficiency of the system’s performance.Security administrators deal with network security and computerspecialization. Security administration includes all the generalsecurity dealings such as firewall devices in addition toconsultation in their regard (Clemm,2007).The work of a network administrator is to sustain infrastructure.Such infrastructures include routers and switches. He also analysestheir weaknesses inclusive of computers attached to the networks.Maintenance of web server services is done by Web administrators. Theweb server services helps in linking of external and internal websites. Errands performed by web administrators are securityadministration, configuration of software and components, multiplesite management and sometimes software change management (Vacca& Ellis, 2005).
Othersections include computer operators who execute their duties likereplacements of device that have failed and change of back up files.This kind of work necessitates the physical presence of the executoras well as the apparatus being utilized. The computer operator needsthe level of trust like that given to the system administrators. Thisis because they are both dealing with very sensitive issues (Popov,2003).Mail server is administered by a postmaster. Provision, creating,adding or removing is the work of a storage administrator. Some ofsystem administrator’s responsibilities include introducing andincorporating new technologies into obtainable data center settings,identification of potential computer issues and system log analysis,new software and hardware installation and configuration, securityresponsibility, tuning of system performance, responding to userstechnical queries as well as assisting them, routine performancesoftware and system audit, Editing information for the account users,maintaining that all the infrastructures are up and in use,organizing adding and erasing file systems, correcting problemsaccounted for, documenting and arrangement of the system (Clemm,2007).
Largeorganizations divide these tasks among different systemadministrators. For example, applications of a member’s systemupgrade. In small organizations, the system administrator could actas network administrator, application analyst, database administratoror storage administrator. Trying to be a system engineer, systemdesigners or system architects is not a thought that systemadministrators in a large company have. System administrationincludes operations conducted efficiently in parts that create asystem
Networkadministration is a branch of system administration. A networkadministrator oversees network infrastructure like routers andswitches as well as diagnosing dilemmas associated with them togetherwith monitoring computers that are connected to the network. Networkadministration exclusively involves computer networking. It entailsnetwork user setting, distribution management, efficient networkresource operations. Dynamic management and monitoring of networkactivities is required (Popov,2003). The aim of network administration is to show changes oftraffic in the network plus other activities involved with network. It may also include activities like database base administrations forestablishment of integrity, organizations data availability,confidentiality plus provision of support services for the externaland internal users.
Thereforenetwork administration is considered a narrow scope. Systemadministration is considered to be the general word for the systemsand hence we see network administration as a piece of systemadministration. A system administrator can become a networkadministrator but the vice versa cannot be. System administrationincludes other functions of operation away IT systems. Never the lessthese two designations vary in respect to organizations. There arethose organizations that seem to differentiate while others takethese designations as one and the same thing. Large organizationsdivide these tasks among different system administrators, while insmaller organizations the system administrator could act as networkadministrator, application analyst, database administrator or storageadministrator
