And that's just the beginning when it comes to specialized roles for IT professionals in the workplace. 

To determine the best career path, individuals considering a career in information technology need to first understand what the field encompasses and what IT professionals do. 

According to the American National Standard Dictionary of Information Technology, “” (or IT) is defined as, “the art and applied sciences that deal with data and information. Examples are capture, representation, processing, security, transfer, interchange, presentation, management, organization, storage and retrieval of data and information.” 

This definition is deliberately broad, as many modern businesses use computers, software and other telecommunication technologies in all aspects of their operations.

As technology has advanced and more businesses have automated their operations, the roles of IT professionals have expanded even further. Information technology professionals have diverse responsibilities, must navigate a field rife with jargon and technical terminology and are crucial to the success of their organizations. 

A well-functioning IT department is vital to the productivity and organization of any business. There are IT systems and applications designed for every level of operations, from data security to internal communication. In the modern world, industry leaders use these systems to improve production and set new standards for efficiency. Businesses of all types need IT systems to compete and grow in this new environment. Information technology specialists can help businesses succeed in several key ways:

All businesses need to communicate effectively to function and grow. Efficient communication among employees can cut down on overhead costs and prevent waste. IT innovations like communication software streamline information sharing by allowing employees to access systems and exchange files remotely. Managers and their teams can use these digital communications systems to quickly share important internal data with one another, track tasks and interact with customers more efficiently.  

In the digital age, a business's data is a highly sought asset that must be protected. The has increased exponentially over the last 10 years, and approximately 230,000 new malware variants are produced each day.

Cybersecurity issues like data breaches and malware attacks can be devastating for businesses, but IT professionals can protect a company’s sensitive data from theft or accidental exposure by using cybersecurity software and employing strategies such as data sanitization.  

Businesses of all types use internal research to analyze their operations and find ways to improve. This research can be highly beneficial, but its impact is directly related to the data that employees can compile and analyze effectively.

To help their companies compete, IT managers can use tools like qualitative research software to glean valuable insights from large samples of data. These insights can help inform policy changes and guide managerial decisions. 

Companies use information technology in a variety of ways. IT professionals often take on specialized roles to meet their company’s needs. They have numerous important roles in business. These include:

In business, network architects have the critical job of designing a company’s computer network, including physical components, operational procedures and communication protocols. IT professionals use specialized programs like network architecture and administration software to track protocols and ensure optimal functionality. 

The importance of well-functioning networks to businesses has made relative to the national average. As of May 2023, network architects earned between $77,960 and $195,000, with a median wage of $129,840, according to BLS.

The tools used by information technology specialists are divided into two main categories: hardware and software. These two forms of technology are fundamentally different but are often used together to help businesses achieve their goals. Generally, companies need both hardware and software to establish and sustain functioning informational networks.  

Software describes any programmed set of instructions computers follow to carry out tasks. Software can refer to any program or application that's designed to help computers perform a specific function.

Different types of software have different uses in IT. Operating systems like Windows and iOS help computers perform more efficiently at every level, while applications like office suites and database management programs are designed for a specific task or purpose.

Most types of software belong to one of six major categories: 

• Application software: Programs designed for specific tasks (web browsers, games, word processors, media players, video editing programs).
• System software: General software that guides a computer's basic operations and serves as a platform for more specialized applications (operating systems like Windows, Linux, Android or macOS).
• Firmware: Instructional software that's embedded directly into a device’s internal hardware. Peripheral hardware items like printers and scanners have their own unique firmware designed to make their operations more efficient.
• Programming software: Software that is used to help programmers write code for new systems and applications. Examples include debuggers, compilers and programming language editors like Eclipse or Coda.
• Driver software: Software that controls the functions of a specific piece of hardware. Computer components like graphics cards and network cards each have their own “driver” software that guides its operations.
• Utility Software: This type is designed to help IT managers maintain computers, diagnose problems or optimize a specific function. Examples of utility software include antivirus programs, diagnostic scanners and clipboard managers.

Software can improve network function and help employees complete complex tasks faster. Many software systems require a certain amount of hardware to run, so it's critical for IT managers to understand the system requirements for programs they use. 

While software refers to the programs and applications installed on the computer, “hardware” describes the physical parts a computer or computer network needs to function.

IT professionals use two main categories of hardware: the internal parts of the computer and the external devices that provide input or output. Businesses need both types to optimize their network performance.    

The pieces of internal hardware in a computer (also called “components”) are the built-in, physical parts of the device, such as:

• �Ѵdzٳ������Dz�������
• Hard drive
• CPU (central processing unit)
• Video card
• Network card
• Heat sink
• RAM (random access memory)
• Power supply

External hardware devices in IT (also called “peripherals”) are appliances that connect externally to a computer and provide input, output or data storage. External hardware can take on many forms, such as:

• �ѴDzԾ��ٴǰ�����
• �������Dz��������
• Speakers
• �Ѿ������DZ��DzԱ����
• Cameras
• Touchpads
• �ʰ����Գٱ������
• Scanners
• USB flash drives
• Memory cards
