Computer Network Management

Computer Network Management
Today it​ is​ almost inconceivable for a​ business not to​ have computers,​ whether it​ is​ a​ construction company or​ a​ high technology firm .​
When a​ business has more than one computer,​ they are almost always connected together in​ a​ local area network .​
These networks may be more or​ less advanced and therefore more or​ less costly.
Companies invest so much (in terms of​ both money and time) in​ a​ local area networks because there are many advantages that a​ local area network brings to​ a​ business and how it​ is​ administered.
Some businesses use a​ local area network in​ such a​ way they are highly dependent on​ it​ always working .​
If the​ company's network fails,​ then you may see all the​ employees chatting away in​ the​ corridors because they can't do their work .​
This means big losses for the​ company and causes stresses on​ the​ employees .​
All companies must consider their local area networks a​ vital asset and downtime must be avoided .​
This imposes huge demands on​ the​ network staff to​ keep such networks running almost 100% of​ the​ time.
The advantages of​ Computer Network Management
One of​ the​ main advantages of​ installing and maintaining LANs is​ the​ opportunity they create for better communication and cooperation between employees and customers .​
Security considerations: Local Area Network security can be both a​ help and hindrance .​
Comprehensive security is​ beneficial because it​ provides a​ central and safe strategy for data access and disaster recovery .​
All information is​ protected by the​ design and implementation of​ the​ network security solution .​
On the​ other hand,​ interconnecting computers in​ local area networks creates a​ security risk,​ since doing so makes it​ technically possible for intruders to​ access many machines on​ the​ network at​ once .​
Cost considerations: Installing a​ local area network is​ a​ relatively expensive project .​
Servers,​ cabling,​ switches,​ routers and software can all be expensive and should never be purchased without expert advice .​
Keeping the​ network operating and secure also requires a​ lot of​ resources and can be costly .​
Surprisingly,​ a​ local area network can bring a​ number of​ cost savings .​
Sharing resources avoids the​ need to​ purchase equipment for each individual .​
Even more important is​ the​ security that a​ local area network can provide .​
Data loss could cost a​ business a​ great deal of​ money and in​ some cases,​ cause the​ business to​ shutdown altogether .​
Computer Network Management should require a​ consistent routine for data backups with regular checkups of​ data quality - a​ practice that will save a​ company huge sums in​ the​ event of​ a​ mishap.
Computer Network Management: preliminary analysis phases
The first phase of​ computer network management is​ to​ determine the​ source of​ the​ problem (a preliminary study that looks into several options of​ differing scope may be useful here) and defining it​ in​ a​ specification of​ requirements .​
Examples of​ what should be evaluated are different network operating systems,​ mail systems,​ and other applications .​
the​ choice of​ hardware components should also be evaluated .​
This phase is​ generally aimed at​ establishing what the​ system should do,​ not how it​ should do it .​
Computer Network Management: design phase
The purpose of​ design phase is​ to​ determine how the​ requirements of​ the​ specification are to​ be met .​
The current approach to​ large,​ complex projects is​ to​ break them down into smaller,​ more manageable subprojects.
Computer Network Management: implementation phase
This phase involves the​ physical installation of​ the​ local area network .​
Cables are run,​ software is​ installed,​ and computers and other hardware are put in​ place .​
Computer Network Management: integration and system testing phase
In this phase,​ commissioning of​ the​ network begins,​ and routines are adapted to​ users and the​ operating personnel .​
the​ system must be tested,​ both to​ ensure that the​ network meets the​ requirements set out in​ the​ specification and that it​ is​ stable enough to​ perform the​ central function it​ has in​ the​ organization .​
Computer Network Management: operation and maintenance
Local area networks have complex operating routines .​
This is​ because there may be serious consequences when faults occur or​ unauthorized persons gain access to​ the​ system .​
Many companies have employees devoted solely to​ take care of​ running and maintaining computer networks .​
These system administrators may deal with network issues such as​ performance,​ reliability and security of​ both hardware and software.
Computer Network Management: tools
Although an​ organization may have computer administrators on​ site,​ they must also monitor the​ network more than eight hours a​ day .​
In fact,​ some of​ the​ worst trouble that arises with networks can happen during the​ night hours when nobody is​ using the​ network .​
With the​ right computer network management tools,​ your organization can receive the​ security of​ knowing that problems will be foreseen,​ prevented,​ and taken care of​ - and that your network administrator can be notified at​ a​ moment's notice,​ should anything go exceptionally wrong.
