computer networks

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.
