The Harvard Business Review coined the term information technology in order to differentiate between computers that are designed for a limited number of purposes and general-purpose devices that can be programmed to perform any task. As the IT industry evolved from the mid-20th century, computing capability increased, while device cost and energy consumption decreased, a cycle that continues today when new technologies emerge.
What does information technology encompass?
The IT department ensures that the organization’s systems, networks, data and applications all connect and function properly. The IT team handles three major areas:
we provide development and maintenance across a range of IT-related services, including: servers, networks and storage.
monitors, optimizes and troubleshoots the performance of applications, services and infrastructure.
oversees the security and governance of applications, services and infrastructure.
Most IT staff have different responsibilities within the team that break into several key areas including:
Administration. Administrators handle the day-to-day deployment, operation and monitoring of an IT environment, including systems, networks and applications. Admins often perform a range of other duties such as software upgrades, user training, software license management, procurement, security, data management and observing adherence to business process and compliance requirements.
Support. Help desk staff specialize in answering questions, gathering information and directing troubleshooting efforts for hardware and software. IT support often includes IT asset and change management, helping admins with procurement, handling backup and recovery of data and applications, monitoring and analyzing logs and other performance monitoring tools and following established support workflows and processes.
Applications. Businesses rely on software to perform work. Some applications are procured and deployed from third parties, such as email server applications. This means that many organizations retain a team of skilled developers to create applications and interfaces for delivering critical business capabilities. Applications might be coded in a wide array of popular languages and integrated with other applications to create smooth and seamless interactions between different applications. Developers might also have to create interactive business websites or even design mobile apps from scratch. If you’re an agile company, then developers should be involved in IT operations as well. To accommodate the modular development paradigm, it’s really important for developers to know how to deploy code.
Compliance. Businesses are obligated to observe varied government- and industry-driven regulatory requirements. IT staff play a major role in securing and monitoring access to business data and applications to ensure that such resources are used according to established business governance policy that meets regulatory requirements. Such staff are deeply involved with security tasks and routinely interact with legal and business teams to prevent, detect, investigate and report possible breaches.
Why is information technology important?
Businesses worldwide become more competitive with data in hand. Without it, many businesses wouldn’t be able to make decisions about their product and marketing strategies.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
Pervasive computing has become an inherent part of our workplace and personal lives. As such, IT is now critical for any company looking to stay competitive. Computing has gone beyond just laptops or desktop computers too – smartphones, smartwatches and other devices are now commonplace in all walks of life. Computing devices are more common than ever. Newer models can sync up with each other, so you can move between them without missing anything. Most people also have multiple devices, like phones, tablets and laptops. Some even have game consoles and doorbells!
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, perilous environment that requires IT expertise for management, security, maintenance and reliability.
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 nearing the end of their operational and maintenance life cycle 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 repurposed or decommission and dispose of the old servers.
Security monitoring. Businesses routinely employ tools to keep an eye on application usage, network activity, & system issues. IT staff are alerted when they detect potential threats or non compliant behavior–such as a user unintentionally trying 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 road map. Operations staff posts each iteration of the new mobile application for download and deploy 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 are often in charge of architecting a high-availability cluster to provide greater performance, resilience for the application – in the event of single outages. This is because when one server goes down, there’s still another one with all your content/information on it.vThis 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.
