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.

Help answer the question about computer hardware
Is it cheaper and better to replace computer hardware or just buy a new computer?Our dell is broken. The CPU is clogged and the motherboard is damaged. It keeps shutting off saying that it is "due to a thermal event". Please explain the cost difference between the two options considering these following things:
-if we buy a new computer we would have to pay to have someone set up the networking and we would have to purchase anti-virus softwares.
- we also have no idea how much it costs to replace hardware because we are not sure to what extent the hardware needs to be replaced?
Could someone give us a minimum and maximum expected cost quote?
There is money, especially if you want to consult. One drawback is there is a bias against anyone who isn't a professional programmer.
You can absolutetly brilliant, but if you aren't a programmer there is a view that your just a step above working at Best Buy.

I think it depends more on the field/position you pick than the major. Try this link for network administrator salaries:

If you want to work on networks you probably need to know basic shell scripts the most and some VB.NET. VB.NET has some tools available that you want to customize per network. Shell scripts on UNIX/LINUX are the forefront. You have to know them well, and they can be written in a number of different ways. You can use the OS native language, or even write them in C/C++ or any other kinds. You don't need to know it "well" for your first job, but you need to know it and how it works. Once you get your first job, any job after that you will want to know shell scripts very well.

A degree from DeVry will help you especially if you go onto to the Bachelors in Multimedia Design and Development.
Have you ever taken an appitude test. You may test high in this field where I would not. They do prepare you but on the job training is the best.
1. asset management – applications and methods for real time location services
active rfid (and to a more limited degree passive rfid) is being leveraged in the health care industry, retail, etc. to manage to high value, mobile assets. as the costs associated with these systems fall, what are the potential applications for network management to leverage this technology?
2. on a change control system
that might not be a good description, but what i'm talking about is being able to implement a change control system that applies rigorous restrictions on any changes being made without the change having been approved. as you may or may not know, most issues occur because someone changed something, and they often times do this outside of the change control system. so how do we manage changes made to the infrastructure concretely? probably the nexus of change and configuration management, and ALL access to ALL infrastructure probably needs to flow through a central (or several points) of control. but those points of control need to understand what is being accessed, by whom, at what level, what they are doing, and if what they are doing has been approved (or is simply generally allowed).
