Information Technology (IT)

Information Technology (IT)

Information technology (IT) is the use of any computer, storage, network, and other physical devices, infrastructure, and processes to create, process, store, protect, and exchange all forms of electronic data. IT is generally used in the context of business operations, as opposed to technology used for personal or recreational purposes. Business use of information technology includes both computer and communication technology. Harvard Business Review coined the term IT to distinguish between machines that are designed for a specific purpose to perform a limited range of functions, and general-purpose computing machines that can be programmed for different tasks. As the IT industry has evolved since the mid-20th century, computing capacity has increased while device cost and power consumption have decreased, a cycle that continues today as new technologies emerge.

What does information technology include?

IT Applications departments ensure that an organization’s systems, networks, data, and applications are all properly connected and functioning. The IT team addresses three main areas:

  • Deploy and maintain business applications, services, and infrastructure (servers, networks, storage).
  • Monitor, optimize, and troubleshoot application, service, and infrastructure performance.
  • Oversees the security and governance of applications, services, and infrastructure.

Most IT staff fall into several key areas within their team:

  • Management:
  • Administrators handle the day-to-day deployment, operation, and monitoring of the IT environment, including systems, networks, and applications. Administrators often perform a variety of other tasks, such as software updates, user training, software license management, acquisition, security, data management, and observing business processes and compliance requirements.
  • Support:
  • IT Support Help Desk staff specialize in answering questions, gathering information, and directing hardware and software troubleshooting efforts. IT support often includes IT asset and change management, data and application acquisition, backup and recovery processing, log monitoring and analysis and other performance monitoring tools, and change management to support compliance with established workflows and support processes.
  • Request:
  • Businesses rely on software to do their jobs. Some applications, such as email server applications, are purchased and distributed by third parties. However, many organizations have experienced developer staff who create applications and interfaces, such as APIs, needed to provide critical business functions and services. Apps can be coded in a variety of popular languages ​​and integrated with other apps to create seamless and seamless interactions between different apps. Developers can also be tasked with creating interactive business websites and developing mobile applications. The trend toward agile or continuous development paradigms requires developers to become increasingly involved in IT operations, such as application deployment and monitoring.
  • Compliance:
  • Companies must comply with various government and industry regulatory requirements. IT staff play a critical role in protecting and controlling access to business data and applications to ensure that these resources are used in accordance with established business governance policies that meet regulatory requirements. These employees are deeply involved in security operations and routinely interact with legal and business teams to prevent, detect, investigate and report potential breaches.

Why is information technology important?

Data is said to be the driving force behind industries around the world. It may be an exaggeration, but few companies, large or small, can remain competitive without the ability to collect data and turn it into actionable information. IT provides the means to develop, process, analyze, exchange, store and secure information.

Data processing plays an important role in key business practices such as:

  • product development and design;
  • marketing and market research;
  • sales and billing;
  • customer development and retention;
  • accounting and tax;
  • human resources and salaries; why
  • Compliance with the Code.
  • Information technology has penetrated almost every aspect of business and many aspects of personal life. The ubiquity of computing, also known as pervasive computing, is another reason why IT matters. Computing devices have gone far beyond personal computers and servers. Today, all businesses and most people own and use multiple computing devices including phones, tablets, laptops, game consoles and even doorbells, thermostats, vacuum cleaners and many kitchen appliances.

Almost all of these devices that are part of the IoT leverage the Internet, interconnecting billions of devices around the world. It is a complex and potentially hazardous environment that requires IT expertise in management, security, maintenance, and reliability.

Examples of information technology.

So how will IT get involved in day-to-day business? Consider five common examples of IT and teams in the workplace.

  • Server update:
  • One or more servers in a data center are nearing the end of their operational and maintenance lifecycle. The IT staff selects and purchases replacement servers, configures and deploys the new servers, backs up applications and data on the old servers, transfers those data and applications to the new servers, verifies that the new servers are working properly, and then Change use. Or withdraw and delete. old server.
  • Security monitoring:
  • Companies routinely use tools to monitor and record the activity of applications, networks and systems. IT staff are alerted to potential threats or non-compliant behaviors, such as users trying to access restricted files. View logs and other reporting tools to investigate and determine the root cause of alerts and take immediate action to remediate and remediate threats. This often leads to changes and improvements in security posture that can prevent similar events in the future.
  • New software:
  • The company determines the need for a new mobile application that allows customers to log in, access account information, or conduct other transactions from their smartphones and tablets. Developers work to create and improve appropriate applications according to a planned roadmap. Operations staff releases each iteration of a new mobile app, downloading the app’s backend components and deploying it to the organization’s infrastructure.
  • Business improvement:
  • Businesses require greater availability of critical applications to support revenue or business continuity strategies. IT staff may need to design high availability clusters to provide higher performance and resiliency to applications so that they can continue to function in the event of a single outage. This can be combined with improved data storage protection and recovery.
  • User Support:
  • Developers are building major updates for critical business applications. Developers and admins work together to create new documentation for updates. By distributing updates for limited beta testing, IT staff can develop and deliver comprehensive training that prepares all users for the final release of new versions, while allowing a small group of users to test new versions.

Information technology vs computing

When searching for jobs in the IT field, you will likely come across the term computer science. While there is some overlap between information technology and computer science, both are distinct disciplines with different courses of study to prepare for jobs in either field.

Information Technology

Information technology is generally related to the application of technology to deal with business problems. As such, the IT workforce is geared toward mature technologies, such as hardware systems, operating systems, and application software. IT proficiency is required to identify the hardware and software components that should be used to improve a particular business process.
