What Is Information Technology?

Information technology, or IT, is the use of computer hardware, software, and related systems to support activities on computers and the Internet. IT is a broad field of study that incorporates all aspects of computer science and engineering and many other areas.

Information technology is an integral part of business management today, but it’s not limited to just the office environment. It’s an essential tool for any organization looking to expand its reach across multiple platforms and markets.

Information technology refers to accessing information through computer systems and devices. Our daily activities are influenced heavily by information technology, including our workforce, business operations, and personal access to information.

The IT industry has a tremendous impact on our everyday lives, regardless of whether we store, retrieve, access, or manipulate data.

Everyone utilizes information technology, from multinational corporations to one-person shops. It is used to manage data and to innovate processes by global companies.

Flea market sellers even utilize smartphone credit card readers to collect payments, and street performers distribute Venmo names to collect donations. Using a spreadsheet to catalog which Christmas presents you bought, you’re using information technology.

Examples of information technology

Examples of information technology include:

  • Computer hardware: The physical components that make up a computer system, such as the motherboard, CPU, RAM, and hard drive.
  • Operating system: A program that manages tasks and resources on your computer.
  • Software applications: Computer programs that perform functions on your computers like word processing or spreadsheets.
  • Networked systems: A computer network comprises interconnected computers and peripherals.

What Does It Encompass?

It is a broad term used to describe the application of technology to solving business-related problems. An IT department member solves big and small technical issues with others. It can break down a department’s primary responsibility into three categories:

  1. IT governance refers to the policies and procedures that ensure IT systems are correctly maintained and functioning according to the requirements of an organization.
  2. IT operations: A department’s daily tasks can be grouped under this category. It includes providing technical support, maintaining networks, performing security tests, and managing devices.
  3. Hardware and infrastructure: IT infrastructure’s hardware and infrastructure component are covered in this focus area. Among the pillars under this umbrella are setting up and maintaining IT equipment, such as routers, servers, telephone systems, and laptops.

Why Is Information Technology Important?

IT systems play an increasingly significant role in global connectivity and operations in the modern era. IT services ensure that systems run smoothly, connect networks, and protect data.

Artificial intelligence and data analytics are also used extensively in the IT sector. Businesses can enhance operational efficiency and resource utilization by integrating smart technologies to increase speed and market coverage.

Information technology workers are expected to manage a variety of rapidly expanding functions:

  • Data Analytics: Increasingly, social media, websites, and third-party platforms generate data streams for businesses, creating the need for advanced computing, AI analytics, and cloud tools, as well as a need for professionals in these areas.
  • Cloud Technologies: It is common today to see cloud platforms and serverless operations replacing server farms and server rooms. In serverless operations, data centers and cloud service providers maintain infrastructure.
  • Mobile and Wireless Infrastructure: For companies to support remote or mobile working, they need to create strong networks and cloud platforms that employees can access anytime and anywhere. In addition to such solutions, developers and managers are in high demand.
  • Network Bandwidth: It is becoming increasingly popular to use video communication. To manage the technology infrastructure, it is also necessary to have a high network bandwidth and a lot of expertise.

Hardware Vs. Software

A large part of the job of an IT department is to deal with hardware and software. Additionally, it is necessary to maintain the hardware.

However, what counts as hardware? In addition, what exactly is software? This distinction needs to be understood.

A computer system’s hardware includes all its parts. The hard drive, motherboard, and central processing unit are all parts of the computer’s hardware.

A computer’s hardware can also include peripheral devices like a mouse, keyboard, and printer that connect to the outside of the computer.

However, some tablets and smaller laptops come with keyboards and mice built-in. Any computer or network component that is physically touchable and manipulatable is hardware.

You can physically change hardware, but software cannot. The software also includes programs, operating systems, and applications stored electronically.

How does this distinction apply to IT careers? It is easy to find IT jobs requiring hardware and software knowledge.

The software that controls those hardware components may take up most of the time IT staff spends configuring elements. Additionally, IT professionals are responsible for deploying and setting up user software applications. Furthermore, IT professionals assemble and deploy software programs for users.

How Is Information Technology Used In Business?

There are many ways that information technology helps businesses stay competitive in today’s economy:


Using IT security systems such as firewalls, encryption, and data backup measures protects sensitive data from being stolen by hackers who may try to infiltrate a network by exploiting vulnerabilities in software or hardware.

You can access data stored on a server remotely if the proper credentials are provided. It allows a hacker to access any files stored on the server if they gain access through an open port on which they have been allowed access.

Digital Advertising & Marketing

Digital advertising allows businesses to reach customers through digital channels such as websites, social media pages, and mobile apps. Digital marketing allows businesses to target their audience more effectively than traditional forms of advertising because they know to who they want their message delivered – whether through search engines or content marketing strategies like blogs or podcasts.

Operational Efficiency

In addition to understanding the cash flow needs of businesses, IT can save time and space. Managing inventory costs and delivering products is easier with inventory management technology. Internet meetings can save executives time and money, especially during the Covid-19 era, when everyone is locked inside their houses.

Online Payment Transfers

The fastest way to do business now is through digital currency transfers. Invoices can be sent by email and paid afterward, which saves time and money.

Relationship with Clients

Information technology helps companies manage and build relationships with customers. CRM systems cover the entire business-customer relationship to gain a deeper understanding. For instance, the center has information on the customer’s order history, shipping details, and a tutorial manual that explains how to complete the project effectively.
