Abstract

Information technologies (IT) and information systems (IS) have profound significance across various sectors of society, including healthcare, business, education, government, and beyond. First, IT facilitates instant communication globally through email, messaging apps, video conferencing, and social media, revolutionizing how individuals and organizations interact, collaborate, and share information (Hacker et al. 2020; Tang and Hew 2020).

Secondly, the Internet and digital libraries provide worldwide access to vast amounts of information, what makes knowledge and education available to everyone, empowering individuals to learn and stay informed on diverse topics (Haleem et al. 2022). Another aspect of IT systems in various industries is that they automate tasks, streamline processes, and improve workflow efficiency. This reduces operational costs, enhances productivity, and allows organizations to focus on strategic goals (Mithas and Rust 2016).

IT and IS allow businesses to reach international markets, efficiently manage supply chains, and securely conduct online transactions enhancing global trade and e-commerce (Chang et al. 2020; Kwilinski et al. 2019). Information technologies and systems drive innovation in research and development across fields like medicine, engineering, and environmental science (Ismagilova et al. 2019). High-performance computing, simulation models, and big data analytics accelerate scientific discovery and problem-solving (Asch et al. 2018; Chen et al. 2016).

IS enables personalized experiences and tailored services through data analytics and artificial intelligence. This includes personalized medicine, targeted advertising, and customized learning experiences (Fan and Poole 2006; León et al. 2021; Shang and Chiu 2022). As digital transactions and data sharing increase, IT's role in safeguarding personal information and preventing cyber threats becomes critical. This includes encryption, biometric authentication, and compliance with data protection regulations (Diwan 2021; Walton et al. 2021).
