What is Information Technology?

In the early days of information technology, some of the industry’s leading professionals were self-taught people who mastered computers as they became increasingly common in the modern workforce. Today’s information technology professionals may have the same independent spirit, but also need to be well-versed in the common computer technology and programs that are used in a variety of organizational settings. Whether you want to work in education, business, government, healthcare, or another type of organization, the best way to start a successful career in modern information technology is through a formal information technology or computer science degree program.

Information technology professionals have to start with the basics of computer programming. Though many people in the field will never actually have to write any programs, but will, instead, work with existing software, understanding programming is a critical part of any information technology job position. Therefore, students must be familiar with C++. This computer language is considered a hybrid language and is general-purpose object-oriented programming language with the convenience of having pre-defined classes. It is used in a wide variety of programming scenarios.

While you may not ever tackle programming in your professional life, there are three areas of information technology study that every computing professional will have to understand: hardware, software, and security. Computer hardware refers to the physical components of a computer or computing system. You are probably already familiar with the hardware that most users have on or in their own computers: motherboards, central processing units (CPU), random access memory (RAM), hard drives, solid state drives, optical drives, video cards, power supplies, monitors, keyboards, mice, heat sinks, data cables, fans, battery backups, webcams, flash drives, printers, speakers, tablets, sound cards, and modems. However, as an IT professional, you will be expected to understand network hardware like: routers, network switches, repeaters, bridges, access points, printer servers, firewalls, and cables or wireless communication devices that allow network computers to communicate with one another.

Software refers to computer data or instructions and is subdivided into two groups: system software and application software. System software runs the computer or network, while application software is task-specific. IT professionals are expected to be proficient with today’s most commonly used software, which includes Microsoft applications for general office usage, but may also include very industry-specific programs in some areas.

Computer security refers to protecting a computer or computer system. Many people think of computer security strictly in terms of protecting the software or the data stored on a computer or network from virtual attacks. While this type of security is important, it is equally important to consider the physical security of hardware; if hardware is accessible, then the data on the computer is vulnerable.

If you explore systems analysis and design, the you will need to combine all three of those components to create a system that balances the need for user-friendliness with the need for security. System designers must be able to anticipate the needs for a system, design the system components, chose the software to run on the system, and possibly design databases that can manage data and help coordinate between users. [ Show Less ]

E-commerce benefits and organizational impacts in developing economies
Both articles and their extensive empirical and theoretical research have a wealth of insights and intelligence that brings e-commerce into a more realistic and pragmatic perspective. Starting with Exploring E-commerce benefits for businesses in a developing country (Molla, Heeks, 2007) that authors explain how they have interviewed 92 businesses in South Africa who have moved beyond the basic stage of ecommerce as defined by the 6-point e-commerce capability indicator cited in their article (Molla, Heeks, 2007). In citing this scale the authors contend that the much-hyped benefits of e-commerce surrounding operating efficiency gains including lower transaction costs and greater fluidity and flexibility of e-commerce are in fact not occurring in the emerging economy of South Africa. Instead, the authors state that the greatest gains are being made in the area of intra- and interorganizational communication and collaboration, clustered primarily in services industry as evidenced by their cited research (Molla, Heeks, 2007). This is certainly the case in Brazil where the continued growth of e-commerce has succeed while other nations have failed mainly due to the exceptional stability of the nations' banking system, strong laws and regulations to protect e-commerce and online commerce, and an infrastructure that makes automating supply chains more achievable than many other regions and nations of the world (Paulo, Dedrick, 2004). Brazil is also unique in that is government subsidizes new ventures and seeks out global technology partners, including Intel, for its e-commerce and infrastructure-dependent industries (Callaway, 2008). Juxtaposing the growth of Brazil is the stagnation of South Africa as is shown in the analysis, which implies e-commerce is better at breaking down the walls of organizations and getting them to work together more effectively than it is in driving top-line revenue from transactions., This consistent with the more pragmatic and practical studies of e-commerce adoption in emerging nations that show e-commerce system development and implementation will teach a business more about itself than it had never considered prior to the implementation (Alemayehu, Heeks, 2007). The process of creating an e-commerce strategy including the process and system integration, coordination of product and services catalogues, redefining and clarification of pricing, and the ability to define expediting processes for service and service recovery of negative customer events all force a business to grow faster than it had anticipated (Standing, Benson, 2000). Small businesses enter e-commerce thinking the big pay-off will be increased top-line revenue growth and greater transaction efficiencies (Molla, Heeks, 2007). Small businesses in commodity driven industries will also do this to specifically drive down the cost per transaction and pool purchasing power to gain an advantage in negotiating with suppliers (Salcedo, Henry, Rubio, 2003). All of these actual benefits are completely different than the much-hyped and promoted benefits of e-commerce being frictionless commerce throughout a supply chain, greater revenue growth at lower transaction costs, and ease and speed of generating customer loyalty, all contributing to skyrocketing profitability of an enterprise (Romano, 2009). All of these benefits accrue, in actuality, to oligopolistic firms who have the infrastructure, from a corporate IT staff to a well-known brand and the ability to selectively disintermediate their own supply chain to gain the much-hyped transaction cost efficiencies (Molla, Heeks, 2007). The greater the global market power of a company and its commanding position in an oligopoly, the more it can enforce its market-maker statue and drive change (Alemayehu, Heeks, 2007). Molla and Heeks (2007) deflate the hype of Transaction Cost Theory and its corollary of disintermediation by showing through their research that perfect competition doesn't exist in e-commerce globally and is especially problematic in emerging countries due to the lack of value chain integration and transparency. The authors also make an excellent point that the main catalysts or fuel of e-commerce growth in many nations is market research and mass customization (Molla, Heeks, 2007). There are myriad of examples of how e-commerce combined with mass customization has led to explosive, profitable growth on the part of companies with Dell not only reaching over $1B in revenues from online sales but also achieving double-digit inventory turns and extensive operational efficiencies at the same time (Luo, John, Du, 2005). The authors contend that for many emerging nations this however is not possible given the lack of trust and adoption of e-commerce, and the lack of alacrity and accuracy in complex supply chain relationships including a lack of clarity in communications and procurement performance (Molla, Heeks, 2007). Contrasting this however are the effects of a stabilized and trusted banking system in Brazil for example (Brazilian e-Commerce, 2005). The greater the trust levels in a given nation's financial system the higher the level of e-commerce adoption, even in highly collectivist cultures (Joia, Sanz, 2005). The authors continue with a triangulation of market performance, communications and transaction cost reduction, showing how e-commerce is more of a catalyst of organizational synchronization than a platform for selling more online (Molla, Heeks, 2007).
