What is information technology and what does it encompass?

The most basic information technology definition is that it's the application of technology to solve business or organizational problems on a broad scale. No matter the role, a member of an IT department works with others to solve technology problems, both big and small.
There are three primary pillars of responsibility for an IT department:
  1. IT governance: This refers to the combination of policies and processes that ensure IT systems are effectively run and in alignment with the organization’s needs.
  2. IT operations: This is a catchall category for the daily work of an IT department. This includes providing tech support, network maintenance, security testing and device management duties.
  3. Hardware and infrastructure: This focus area refers to all the physical components of IT infrastructure. This pillar of IT includes the setup and maintenance of equipment like routers, servers, phone systems and individual devices like laptops.
Even though an organization’s IT department handles many different functions and plays a critical role in keeping things running, Andrey Prokopchuk, head of IT at Belitsoft, says the perfect IT department is the one you aren’t even aware of. This means that they are able to automate and create processes for many of their daily tasks, so that the business continues to run smoothly. The ideal IT department is also aligned with the business’s goals and transparent in its processes in a way that the rest of the business can understand and provide input on.



Why is information technology important?

Simply put, the work of most organizations would slow to a crawl without functioning IT systems. You’d be hard-pressed to find a business that doesn’t at least partially rely on computers and the networks that connect them. Maintaining a standard level of service, security and connectivity is a huge task, but it’s not the only priority or potential challenge on their plates.

  • Data overload: Businesses need to process huge amounts of data. This requires large amounts of processing power, sophisticated software and human analytical skills.
  • Mobile and wireless usages: More employers are offering remote work options that require smartphones, tablets and laptops with wireless hotspots and roaming ability.
  • Cloud services: Most businesses no longer operate their own “server farms” to store massive amounts of data. Many businesses now work with cloud services—third-party hosting platforms that maintain that data.
  • Bandwidth for video hosting: Videoconferencing solutions have become more and more popular, so more network bandwidth is needed to support them sufficiently.
Based on the volume of these needs, you probably won’t be too surprised to learn that employment of computer and information technology occupations is projected to grow 13 percent from 2016 to 2026, which is faster than the average for all occupations, according to the Bureau of Labor Statistics.*



Hardware vs. software

You know that working with hardware and software is a large part of an IT department’s work, but what counts as hardware? And what’s software? Let’s break down this important distinction.
Hardware includes all the physical parts of a computer system. This includes hardware installed inside the computer like the motherboard, central processing unit and hard drive. Hardware also describes components that can be connected to the outside of a computer like a keyboard, mouse and printer. Keep in mind though that some tablets and smaller laptops integrate items like a keyboard and a mouse within the device. Basically, hardware is any part, component or device related to computers and their networks that you can physically touch and manipulate.

So how does this distinction apply to an IT career? Nearly every IT job requires a blend of hardware and software-based know-how. Some IT workers may spend more time working with configuring hardware components, but those components are also governed by software. Additionally, IT professionals are responsible for deploying and setting up software applications for users.
