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 ]
