Network Engineering : A Network Engineer

“Networks are all around us. They are in our walls, in the air. At schools, hotels, hospitals, even coffee shops. Always there, always on…This power exists today. In our routers. In our switches... . (Cisco, n.d.)

One thing that I believe that I learned that is important is the different areas of a network architecture that you must support as a network guy to have a reliable network. These are Security which is keeping data safe from people who are not supposed to have it and having a secure network that other people cannot alter. The next part it (QoS) which is making sure the correct data gets privileges when there is congestion. Fault tolerance which is have

This assignment will be mainly about network components and how do they operate, what are their functions and what are their flaws.

I have decided to go into Networking for many reasons, one of those reasons is that it’s the right kind of job for me, as I’m known as the “computer guy”,“the nerd”, “the computer nerd”, and “the IT guy”. The job title for the networking job I’m looking into is known as none other than “Network Administration”. In this amazing job you get to do many important things for any organization that requires internet or computer services. Network administration requires you to: make sure the internet is running smoothly, make sure all systems are fully upgraded for full performance, troubleshoot any problem that happens to the computer system and network system, train all the people having to do with that

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

You must stay aware of not only those but the industry trends on how to deal with them and what’s effective. You must get educated on the hardware and tools you’ve got. Whether learning on your own or with instructor-led training, you need to have a solid networking foundation and a clear understanding of all 7 layers of the OSI model. For Security, you build off of that foundation through familiarity with attack vectors and hours of poring over vulnerability notices and mitigation plans. You can’t just learn this through book reading. Jeff found that hands-on experience is best because books tend to describe ideal-state situations. In his 25 years of IT work, that was rarely the case. He never experienced setting up a networking from a “tabula rasa” state and more often than not he was either trying to clean up someone else’s mess or trying to make the old hardware work to align with new business constraints. For him, the first part of his career was configuring a network according to someone else’s vision of how the network needs to be set up to meet those business needs. The best way to strive in this industry is to ‘GET A MENTOR’. I bold this to emphasize his importance on this. Finding someone out there that knows more about networking or the network you are working on is pivotal. Learn from them, go to the area user’s groups and make some new friends and exchange ideas. He was surprised at how much he picked up from veterans and how willing they usually

Are you staff on any other servers currently?: Yes, I currently own a server but would like to take a break to see how getting staff on another server would be.

As the network engineer, you have been asked to standardize network configurations across the Devry University campus.

Enhancing the security of routers is important to avoid unauthorized users change configuration settings and avoid unauthorized information and routing from entering. For instance, clear text authentication takes advantage of more flexible key management capabilities.

The security engineer will install and manage an organization’s security systems across its network. He will also monitor and react to their output.

The presence of such a label, however, has to be indicated to the router/switch. In the case of Ethernet frames this is done through the use of EtherType values 0x8847 and 0x8848, for unicast and multicast connections respectively.[1]

When a CPU is composed of two or more processors, each one is referred to as a(n) ________.

“They are responsible for LANs, WANs, network segments, and Internet and intranet systems. They install and maintain network hardware and software, analyze problems, and monitor networks to ensure their availability to users. These workers gather data to evaluate a system’s performance, identify user needs, and determine system and network requirements.” (Labor, 2010) The work environment for these workers is ideally a comfortable well-lit office setting. With the expansion of computer networks they are often able to telecommute from home. The education requirement for these workers is typically a bachelor’s degree but a professional certification may be adequate for some employers. “Experience with network security and maintenance is preferred. Because network administrators are involved directly with people in many departments, good communication skills are essential.” (O'Leary & O'Leary, 2008) Network and computer system administrators can expect to earn an annual salary ranging from $41,000 to $104,070. “Median annual wages of network and computer systems administrators were $66,310 in May 2008. The middle 50 percent earned between $51,690 and $84,110. The lowest 10 percent earned less than $41,000, and the highest 10 percent earned more than $104,070.” (Labor, 2010) The future employment outlook for the network and computer systems administrator is good and

As a child, I grew up enjoying mathematics and science; this led to my dream of becoming an Information Security Analyst by majoring in Computer Engineering in college. I chose this profession because over the past couple of years, the world has become more dependent on technology, which means that there is more technology that needs to be developed and better network security will need to be implanted to meet the progressing world’s standards. By being in this profession, there will always be job opportunities in small and large companies because networks, computers, cell phones and many other gadgets are prone to being compromised. For example, Boeing is a prestigious, global company that is one of the leading manufacturers of cyber security that offers several internship and job opportunities to undergraduates and graduates. Future graduates will be able to learn reliable information on what they need to become an information security analyst because an intensive amount of time was taken to research and find credible sources.

Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.
