Brandon Douglas Bradshaw has studied IT and computer systems for many years and it have become his passion. In his studies she has discovered some very important foundational facts. Computer networks can be defined as an engineering discipline regarding the interaction between devices of computer and computer systems. Routing protocols, networking, routers and entire networking system over the internet services have their details defined in documents termed as RFCs (request for comments). Computer networking is also considered as a discipline of computer science, telecommunications, computer engineering and information technology. It deals with practical and theoretical applications of these engineering and scientific disciplines. There are three kinds of computer networks:
- Internet
- Intranet
- Extranet
Generally a computer network is sets of various devices and computers that are associated to each other having capability to send or receive data. Here is the list of different kinds of computer networks that Brandon Douglas Bradshaw is experienced with:
- LAN (Local Area Network): this is a small network deals with local and small regional area. Like a computer network covering a building.
- MAN (Metropolitan Area Network): This is medium size network deals with a city or state.
- WAN (Wide Area Network): This is a bigger network deals with large geographic area.
- WLAN & WWAN (Wireless LANs and MANs): These networks are the equivalent of the WAN and LAN in a wireless form.
There are all kinds of computer networks that are connected to each other to let the communication be done among various Medias like copper wire cable, optical fiber, coaxial cable, micro wave system, power lines and different wireless technologies. The devices regarding computer set-ups can be operated within a few meters or unlimited distances, depending on its range.
There are many organizations such as insurance companies, railways, hospitals, banks etc that needs real time processing of huge number of transactions via many computer systems in order to interact and communicate with each other via same network. Thus the installation procedure of an entire computer group is very important as well as sensitive also.

If you’re looking for a fast-paced career that combines technology with creativity, check out the field of computer network, systems, and database administration. This dynamic career path reflects the increasing number of computer networks in business today.
In the workplace, computers and computer networks have become an integral part of everyday life. Nearly everyone who works in an office has a computer, and big companies may have thousands of workstations, each with a computer terminal. These computers don’t just sit on desks like little islands; they need to be linked together into one seamless operating system. The ways that computers are linked together include local-area networks (LAN), wide-area networks (WAN), network segments, and Internet and intranet systems. Networks can be very complex, and creating a network of computers is a task that must be performed by highly qualified personnel.
Network and computer systems administrators design, install, and support an organization’s computer network systems. Network and computer systems administrators work in a wide variety of organizations including professional offices, government organizations, small businesses, and large corporations. They analyze problems, maintain a company’s network hardware and software, and monitor networks to ensure their functionality. Administrators may plan, coordinate, and implement network security measures, and they may gather data to identify customer needs and then use the information to identify, interpret, and evaluate system and network requirements.
Systems administrators ensure that the design of an organization’s computer system allows all of the components, including the network, the computers, and software, to work properly together. They are often responsible for maintaining the network’s efficiency, and they monitor and adjust the network’s performance. They continually survey the current computer system to determine future network needs, troubleshoot problems reported by users and by automated network monitoring systems, and make recommendations for future system upgrades.
When the computers in the sales office crash, or when the finance people can’t access their networked spreadsheets, or when the warehouse cannot access the intranet to track a shipment, the company can become paralyzed. A network systems administrator is the person who can, and must, resolve these network issues. It’s an important position.
Education and training are key. A bachelor’s degree is required for many network and computer systems administrator positions. In addition, many employers will demand that applicants have specialized computer network training of the type that may be offered by a career college. The best way to explore your career training opportunities is to log onto a reputable online college directory and compare computer training programs. Choose the ones that are right for you and request free information from the schools. This will allow you to make the best choice for your career education.
Here are some of the program areas that are key to this career field:
• Computers and electronics – Knowledge of circuit boards, processors, chips, electronic equipment, and computer hardware and software, including applications and programming.
- English language – Knowledge of the structure and content of the English language including the meaning and spelling of words, rules of composition, and grammar.
- Mathematics – Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications.
- Administration and management – Knowledge of business and management principles involved in strategic planning, resource allocation, human resources modeling, leadership technique, production methods, and coordination of people and resources.
The career outlook is excellent. According to the U.S. Bureau of Labor Statistics (BLS), in the current decade from 2008 to 2018 employment of computer network, systems, and database administrators is expected to increase by 30 percent, which is much faster than the average for all occupations. Demand for computer network administrators is expected to increase as companies continue to invest in new technologies.
Compensation can be generous. According to the BLS, as of May of 2006, the median annual earnings of wage and salary network and computer systems administrators was $62,130. Not bad!
