What is information technology? A Beginner's Guide to the World of IT (1)

For many people, information technology (IT) is basically synonymous with the guys and gals you call when you need help with a computer problem. While this view of information technology is not entirely wrong, it drastically underestimates the scope of this important career field.

If you want to better understand information technology and the many facets of this field, you've come to the right place. We did our research and spoke with IT industry experts to create this helpful guide for beginners.

What is information technology and what does it include?

The most basic definition of information technology is that it is the application of technology to solve large-scale business or organizational problems. Regardless of role, a member of an IT department works collaboratively with others to solve technology problems big and small.

There are three main pillars of responsibility for an IT department:

  1. IT Governance:This refers to the combination of policies and processes that ensure that IT systems are operated effectively and in accordance with the organization's needs.
  2. IT Operations:This is a comprehensive category for the day-to-day work of an IT department. This includes providing technical support, network maintenance, security testing, and device management tasks.
  3. Hardware and infrastructure:This focus area relates to all physical components of the IT infrastructure. This pillar of IT includes the configuration and maintenance of devices such as routers, servers, telephone systems and individual devices such as laptops.

While a company's IT department plays many different roles and plays a crucial role in keeping things running, says Andrey Prokopchuk, head of IT atBelitsoft, says the perfect IT department is one you don't even know about. This means they can automate many of their daily tasks and create processes to keep the business running smoothly. The ideal IT department is also aligned with business objectives and transparent enough in its processes for the rest of the organization to understand and contribute.

Why is information technology important?

Simply put, without functioning IT systems, most companies' work would progress slowly. You'll be hard-pressed to find a company that doesn't rely, at least in part, on computers and the networks that connect them. Maintaining a standard level of service, security, and connectivity is a daunting task, but it's not the only priority or potential challenge on your plates.

More and more companies want to implement more intuitive and sophisticated solutions. "IT can give a company the edge it needs to outsmart, outrun and outperform its competitors," said Edward Kiledjian, director of information security andtechnology blogger. Let's take a look at the needs that current and future IT professionals will be working on:

  • Data overload:Businesses need to process large amounts of data. This requires massive amounts of computing power, sophisticated software, and human analytical skills.
  • Mobile and wireless uses:More and more employers are offering remote work options that require smartphones, tablets and laptops with wireless access points and roaming capabilities.
  • Cloud services:Most companies no longer operate their own "server farms" to store large amounts of data. Many companies are now working with cloud services - third party hosting platforms that manage this data.
  • Bandwidth for video hosting:Videoconferencing solutions are becoming more popular, requiring more network bandwidth to support them properly.

Given the scale of these needs, you probably won't be too surprised to learn that jobs in computing and information technology occupations are expected to grow by 13% from 2016 to 2026, which, according to theDepartment of Labor Statistics.*

Hardware vs. Software

You know that working with hardware and software is a big part of an IT department's job, but what counts as hardware? And what is software? Let's break down this important difference.

Hardware includes all physical parts of a computer system. This includes the hardware installed in the computer, such as the motherboard, CPU and hard drive. Hardware also describes components that can be attached to the outside of a computer, such as a keyboard, mouse, and printer. However, keep in mind that some smaller tablets and laptops do integrate elements such as a keyboard and mouse into the device. Basically, hardware is any part, component, or device related to computers and their networks that you can physically touch and manipulate.

Unlike hardware, software is not something you can physically change. Software includes all electronically stored data, applications and programs such as an operating system or video editing tool.

How does this distinction apply to an IT career? Almost every IT job requires a combination of hardware and software-based experience. Some IT teams may spend more time configuring hardware components, but these components are also controlled by software. Additionally, IT professionals are responsible for deploying and configuring software applications for users.

In large organizations, IT professionals have a more diverse range of potential focus areas – some may move into strategic planning and managerial roles, while others pursue specialist areas such as cybersecurity.
