Techopedia explains Information Technology (IT)

There are many things involved in IT. For example, take an IT department in a company. There are many people who have multiple jobs and different responsibilities. These responsibilities range from keeping the system and data secure to keeping the network running. There are people who input data, people who manage databases, and people who do programming. There are also decision-makers, such as the Chief Information Officer (CIO), who decide how an IT department will function and which components will be procured.

It also includes the management of data, be it text, voice, image, audio, or any other form. This can also include things related to the Internet.
It gives a whole new meaning to IT, as the Internet has its own territory. It involves the transfer of data, so it makes sense that the Internet would be a part of IT. It has become a part of our daily life and is continuously expanding into new areas.

Examples of information technology

So how is IT actually involved in day-to-day business? Consider five common examples of IT and teams at work:

Server upgrade. One or more data center servers near the end of their operational and maintenance lifecycle. IT staff will select and procure replacement servers, configure, and deploy the new servers, backup applications, and data on existing servers, transfer that data and applications to the new servers, validate that the new servers are working properly, and then repurpose or decommission and dispose of the old servers.

Security monitoring:

Businesses routinely employ tools to monitor and log activity in applications, networks, and system IT staff receive alerts of potential threats or non-compliant behavior -- such as a user attempting to access a restricted file -- check logs and other reporting tools to investigate and determine the root cause of the alert and take prompt action to address and remediate the threat, often driving changes and improvements to security posture that can prevent similar events in the future.

New software: 

The business determines a need for a new mobile application that can allow customers to log in and access account information or conduct other transactions from smartphones and tablets. Developers work to create and refine a suitable application according to a planned roadmap. Operations staff posts each iteration of the new mobile application for download and deploys the back-end components of the app to the organization's infrastructure.

Business improvement: 

A business requires more availability from a critical application to help with revenue or business continuance strategies. The IT staff might be called upon to architect a high-availability cluster to provide greater performance and resilience for the application to ensure that the application can continue to function in the face of single outages. This can be paired with enhancements to data storage protection and recovery.

User support:

Developers are building a major upgrade for a vital business application. Developers and admins will collaborate to create new documentation for the upgrade. IT staff might deploy the upgrade for limited beta testing - allowing a select group of users to try the new version - while also developing and delivering comprehensive training that prepares all users for the new version's eventual release.

Why is information technology important?

It's been said that data is what powers industries worldwide. That may be hyperbole, but few businesses - large or small - can remain competitive without the ability to collect data and turn it into useful information. IT provides the means to develop, process, analyze, exchange, store, and secure information.

Data processing plays a significant role in these core business practices, among others, including:

  • Product development and design.
  • Marketing and market research.
  • Sales and invoicing.
  • Customer development and retention.
  • Accounting and taxes.
  • Human resources and payroll; and
  • Regulatory compliance.

Computing has penetrated practically every part of business and much of our personal lives. The ubiquity of computing - also referred to as pervasive computing - is another reason why IT is critical. Computing devices have evolved well beyond personal computers and servers. Today, all businesses and most individuals have and use multiple computing devices, including phones, tablets, laptops, game consoles, and even doorbells, thermostats, vacuums, and many kitchen appliances.

Virtually all these devices, many of which are part of the IoT, tap into the internet, which interconnects billions of devices worldwide. It's a complex and, potentially, the perilous environment that requires IT expertise for management, security, maintenance, and reliability.

Information technology

IT is generally associated with the application of technology to deal with business issues. As such, the IT workforce is oriented toward developed technologies such as hardware systems, OSes, and application software. Proficiency in IT is required to identify the hardware and software components that should be used to enhance a specific business process. IT pros work with a variety of technologies, such as server OSes, communications devices and software, and applications.

Preparation for an IT career requires basic courses in hardware and software systems. IT degree programs may include subjects such as:

  • Database design
  • Database management  
  • Business Analysis
  • Project management
  • Telecommunications
  • Network Administration
