IT Service Management is a system for managing Information Technology organization systems, focused on customer’s perspective of Information Technology’s donation to the business.

Businesses today lean on a large quantity of communication between customers, partners, workers and human doing duties – all that take place at any granted infinitely short period of time within the Information Technology.

Transaction amount of work which need to be done must have management, even Blue Cross and Blue Shield of Minnesota announced that they has implemented the award-winning ‘CoreFirst’ product by OpTier which is a company makes application management software – who works to increase quality of customer service levels by decreasing the sum of time customers spend finding information and display it as output over customers portals.

Such applications – are for managing transaction loads (amount of work to be done) across different basis layer, for example – Web and application servers and DB.

Each interaction represents a one undivided IT-provided service – such as balance questioning, obtains orders and dealer updates. Each business transaction is made up of complicated sets of ingredient operating across multiple layers and involving different stake holders which holds a share in company. There’s a few IT applications (most of them are PC software) increasing the complexity of activation like this kind of services – when businesses get it hard to promise business service delivery.

On an interview one of the IT companies said that executives compare their escapade in starting this kind of companies to those of The Blues Brothers – a small team decided to take a mission to solve a huge problem.

My name is Donald Carroll. I am the President and Webmaster of Green Planet Fantasy Theater. How did I get here? I have over ten years of work experience in the field of Information Technology (IT). I also have five years of teaching experience as an instructor in both Microsoft and Cisco technologies as well as other networking technologies such as Novell Netware, Unix, and Linux. I am twice certified by Microsoft as a Microsoft Certified Systems Engineer (MCSE), and twice certified by Cisco Systems as a Cisco Certified Network Associate, or CCNA?

The field of Information Technology has been very good to me and is an excellent trade to get into for those of you looking at entering a career or changing careers. As a former instructor, I can tell you that as a prerequisite you must be at least comfortable with using computers; better if you have a knack for fixing them when they break! Those of you who are very familiar with using, repairing, and even building computers are perfectly cut out for the lucrative field of Information Technology.

The purpose of this article is to help you in getting started on the path towards earning your industry standard certifications in the field of Information Technology while also gaining hands on practical experience with computer networks. I will tell you on the next page exactly what to do if you are interested in entering the field of Information Technology, even if you have no experience whatsoever. In the field of Information Technology, it is often not enough to just earn your certifications as employers generally favor IT professionals with work experience.

I will also share with you more about my own background and how it helped me to enter the field of Information Technology.

In the early 1990′s I was working as an administrative assistant, and as part of my duties I learned how to use a number of different computer programs; common business applications including word editors, spreadsheet programs, and databases. After my stay as an administrative assistant, and while I was seeking new and interesting employment opportunities, I sent away for a PC (Personal Computer) home study course, mostly because it came with a PC! I learned computer hardware, and computer software, including operating systems such as Microsoft DOS and Windows version 3.1. (Learning computer hardware and computer software, including operating systems such as Microsoft Windows XP and Microsoft Windows Vista is the first step in training for a career in Information Technology. I will explain more about this on the next page.)

I was also able to connect to the Internet using a modem; at that time, the only real Internet choices there were was “GopherNet”, and the America Online Network. (“GopherNet”, which is still in existence today, allows you to view folders and files on a remote computer, not web pages. The America Online Network has merely changed over the years.) Besides then connecting to a rather bleak Internet, in comparison with today’s Internet, you could connect to what were called “BBS’s”, or electronic bulletin boards. These “sites” allowed you to chat, play online games, and both upload and download content. ( I would have to check to see if any “BBS’s” are still in existence today!)

In 1997 I relocated to the Silicon Valley (San Jose, California), and I began applying around for administrative assistant positions. One recruiter pointed out that I “had a list of computer skills a mile long” between having learned a number of business applications, and having also completed a two year home study course as a PC Specialist. I was offered a high paying short term contract to provide computer support for employees at NEC Computers. I was basically an apprentice to what I would call a “guru” in terms of computer and computer networking skills.

I also entered college again to earn an Associate of Science/Information Systems Degree. After my contract at NEC Computers ended I applied at Honeywell Automated and Industrial Controls, and I accepted a position as a hardware technician. At this point now in my life I was pursuing a second degree in Information Technology, and working in the field of Information Technology, developing on the job skills critical to become a real expert. (At that time, the field of Information Technology was called Management Information Systems (MIS). Later it was changed to Information Specialist (IS), and today it is known as Information Technology (IT)).

That was the beginning for me. I soon continued on to teach networking technologies, and I accepted senior engineering positions with a number of different companies and corporations. I WAS EARNING WAGES and BENEFITS PACKAGES I HAD NEVER DREAMED OF!!! I essentially climbed the ladder from working as a computer hardware technician to working as an instructor, a network engineer, a senior network engineer, and finally as a consultant! Today I work as a contractor and as a webmaster.

If you would like to enter the field of Information Technology yourself PLEASE CONTINUE READING!!! I have myself graduated over four hundred computer networking students, and I can teach you how to learn computer hardware and software, and computer networking. I will tell you what course books to study and how and what certification tests to prepare for.

The field of Information Technology is not about computer programming, or application development; this field is all about the designing, building, maintaining, troubleshooting and repairing both the computers and the computer networks that companies use to store and use their data. In considering computers, there is the computer hardware; the disk drives, cd-rom drives, memory, motherboard, processors, power supplies, mice, keyboards, and other parts and peripherals. There is also the computer software; namely, the operating system, like Microsoft Windows XP or Microsoft Windows Vista, and computer applications or programs, such as Microsoft Office or Adobe Acrobat Reader.

When one or more computers are connected together to form a computer network they are connected using network devices such as hubs, switches, routers, and other network devices. In the field of Information Technology some IT Specialists prefer to work on computer hardware and computer software, and special computers used in a computer network called network servers. Other IT Specialists prefer to work more with network switches, network routers, and other telephone and telecommunications equipment.

If you would prefer to work with networking devices more than with computer hardware, computer software, and servers, you might want to pursue getting certified as a Cisco Certified Network Associate, or CCNA. (The CCNA certification is either one or two exams; you have a choice of taking it as either one or two exams depending upon your preference.) Your duties as a CCNA would revolve more around configuring and troubleshooting network routers and switches, and working with leased line providers and telecommunications equipment. Cisco Systems also offers other more advanced routing certifications beyond the CCNA, namely the Cisco Certified Network Professional, or CCNP, and the Cisco Certified Internetwork Expert, or CCIE.

If you would prefer to work on computers; installing and fixing computer hardware and computer software, and administering network servers and network databases and applications, you might be interested in pursuing first the A+ certification followed by the Microsoft Certified Systems Engineer, or MCSE certification. (The A+ certification exam is given as either one or two exams; one exam is based on computer hardware and the other exam covers special software known to IT Specialists as operating systems. The Microsoft Certified Systems Engineer, or MCSE, is awarded upon the successful completion of seven individual exams.)

Many IT professionals maintain proficiency in computer hardware, software, network servers, and comput

er networking devices such as routers and switches. Many employers demand that their IT staff be able to help employees with simple computer problems while also being able to solve complex network problems on network routers, switches, and even firewall systems. Many positions in the field of Information Technology require an A+ certification, an MCSE, and a CCNA. Other positions require only one of these certifications, plus or many any of a number of other industry standard certifications.



Unless you decide to pursue the Cisco Certified Network Associate, or CCNA certification, you will probably want to begin learning the ins and outs of a single computer before studying computer networking technologies. You can purchase the textbooks for the A+ certification, the MCSE certification, and the CCNA certification at almost any book retailer.

Focus first on the A+ exam material before proceeding to the MCSE exam material and/or the CCNA exam material – this is best if you are an absolute novice. It is also a good idea to set up a small computer network at home to practice with – hands on experience with these technologies is essential to success! It is also a good idea to attend a technical school to learn the basics of networking technologies, but you can study and become proficient with these technologies on your own just as well.

With your A+ certification behind you, you can work as a PC technician, or even as a Help Desk Specialist (helping employees with their hardware, software, and basic network problems.) While pursuing your MCSE and or CCNA, you can apply for positions as a junior systems administrator, network administrator, and even a junior network engineer.

Study your exam materials, setup your own home network that you can use to practice on, and by all means try to meet people who work as IT Specialists so that you can learn more about working in the field of Information Technology. Maybe you can spend a day at work with them working for free as an apprentice? (Companies usually do not mind extra help for free!)

Create a sharp resume’ listing your certifications and/or technical school degrees, and your work experience…if you do not have any work experience, try to get some working with an IT Specialist. Though certifications are important, most employers prefer work experience. Some job interviews have a required technical interview where you are tested on your fundamental knowledge and your ability to troubleshoot and resolve computer and computer network problems.

Once you have passed you A+ certification exams you can begin applying to work as a computer technician (hardware and/or software technician.) From there you can continue your studies in networking, earn your MCSE and/or CCNA, CCNP, or CCIE, and become a network engineer, a senior network engineer, a contractor, or even work as a consultant.

Good luck to you…if you have any questions about the field of Information Technology please feel free to contact Donald Carroll at Green Planet Fantasy Theater.

IT Changing Careers, Cisco Certified Network Associate, Computer Networks

When people hear the words “Information Technology,” the first things that come to mind are computers and the Internet. It may also bring up words like “network,” “intranet,” “server,” “firewall,” “security,” as well as more arcane expressions such as “router,” “T-1,” “Ethernet,” or the mysterious and exotic-sounding “VoIP” (pronounced “voyp”).

In fact, information technology is all of these things, and more. It’s hardly new, however. Information technology is as old as the brain itself, if you think of the brain as an information processor. As far as I.T. being a science, even that goes back as far as the earliest attempts to communicate and store information.

And that is essentially what information technology is: the communication and storage of information, along with the ability to process and make use of the information stored. In this chapter, we’ll begin with a brief history of I.T., what it comprises today, and the different major types of I.T. systems available today.

A Short History of Information Technology

As human societies have grown in size and complexity, so has the need to collect, store and transmit information. While it could be argued that brains represent a form of “bio-information technology,” Greek word “Tektra” – from which we get the word “technology” – really refers to scientific or mechanical knowledge, particularly that which involves the use of tools. Therefore, we’ll begin our journey with humans first attempts to record and transmit knowledge through mechanical means.

The Neolithic Period and the Bronze Age

We might not have thought of it as “information technology” several thousand years ago when we as a species were painting animals on cave walls. But in fact that may be exactly what it was.

Using a combination of tools that included manganese “crayons” and clay that was colored with various pigments, early humans left these images on the walls of a cave near Lascaux, France and on cliffs in the Algerian Sahara.

These have been dated as being approximately 18,000 and 8,000 years old respectively. Unfortunately, there is no way to be certain exactly what message was being communicated (a problem our own descendants 15,000 years from now may very well encounter from what we leave behind!)

Since the images depict animals that were commonly hunted at the time, and given the importance of game animals to a hunting-gathering culture, it’s possible that such images were attempts to present information about such game, or part of a rite designed to ensure a successful hunt.

The invention of writing systems – including pictograms such as hieroglyphics, alphabetic writing and “syllabic” systems – seems to have taken place almost at the same time as the development of agriculture. Agriculture introduced such formerly unknown concepts as land ownership, advanced trade and the accumulation of wealth, which in turn led to more complex societal structures.

As you might expect, this necessitated more detailed and efficient record-keeping. Alphabetic writing has a substantial advantage over pictograms (hieroglyphs), because a relatively limited number of symbols (letters) can be used over and over in infinite combination to communicate nearly anything. (As you will see later, modern I.T. uses only two of these symbols!)

Preserving and storing such information posed certain challenges; information either had to be inscribed on stone or clay tablets (which were heavy) or animal skins, wax tablets or papyrus (which weren’t durable).

The Hellenistic World

The Classical Greeks were the first people of record to attempt to find scientific, rational explanations for natural phenomena. Some of the earliest proto-computers known were mechanical devices developed by the Greeks. One of these was a form of abacus (which also developed and was used in ancient China). The device facilitated and simplified mathematical calculation.

Consider REALLY early Greco-Roman Abacus

Another early computational device was the antikthera, greek in origin. An antikthera was discovered by a Greek sponge diver over a century ago, it was only recently that this 2100-year-old device was reconstructed and shown to be an early form of computer designed to chart the movements of the sun, moon and five planets known at the time.

Early Programmable Devices

By the time the gradual break-up and fall of the Roman Empire was complete in the year 476 C.E., scientific and technological advances in the Western world had ground to a halt. While much of the scientific knowledge of the Greeks was preserved by Irish monks and Arab scholars, it wasn’t until the fourteenth century that principles of engineering were rediscovered and applied to information. The first of these was of course the printing press.

Although the concept of movable type printing had been developed in China some four hundred years earlier, it was Gutenberg’s device in 1447 that revolutionized communications, making it easier and faster to record and disseminate information than ever before. The first truly programmable device would not come along for another 354 years, however.

The Jacquard Loom of 1801 was a product of the Industrial Revolution. This invention used a series of specially punched paper cards that functional as templates, allowing for the automatic weaving of highly intricate patterns. Those punch cards became very significant to computing in the 1950′s, 60′s and 70′s.

The next development was Charles Babbage’s “Analytical Machine” – a fully-programmable computer that unfortunately was never actually built. Babbage worked on designs from 1837 until his passing in 1871. This steam-powered mechanism would have also utilized punch cards, with a central processing unit (CPU) and a form of memory storage in the form of a system of pegs inserted into rotating barrels.

The Analytical Machine would have been capable of storing 1,000 numbers of up to fifty digits each, and perform six different mathematical operations, including the calculation of square roots. Babbage’s ideas were incorporated into early electronic computing devices being developed in the late 1930′s and 1940′s, although not all of these were actually programmable. The first truly programmable computers – able to store and use information – did not come into common use until the 1950′s, and yes – made use of punch cards (those born before 1965 may remember playing with them).

Of course most people born in the 70′s, 80′s and 90′s just take for granted that the Information Technology we have today is from fairley recent developments in science, mechanics and electronics. But we know different now don’t we. And therefore can better appreciate what we have available to us now.
