Globalization  Video conferencing reduces travel and lodging costs. ICT has enabled the world economy to become a single interconnected system that allows one to contact a business or family member and bring nations and people closer together. 3. Cost - effectiveness  Sending an e-mail seems free, even when it isn't, and it is unquestionably less expensive than making a phone call. ICT has also aided in the automation of commercial procedures, reorganizing firms to make them incredibly efficient. ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict  Advantages and Disadvantages of ICT ADVANTAGES 4. Greater Accessibility  ICT has enabled businesses to be automated, providing customers access to a site or voicemail seven days a week. 5. Bridging the culture clash  More access to technology has made it possible for individuals of different cultures to speak with one another and exchange ideas, increasing awareness and decreasing prejudice. 6. Creation of new employment  The emergence of new, fascinating occupations has been the most significant benefit of ICT. 7. Education  Computers, their programming, and the Internet have made it possible to educate people in ways that were impossible for earlier generations. ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict  Advantages and Disadvantages of ICT ADVANTAGES 8. Complicated Structure  Teachers can explain the complex system and lesson and ensure students understand it thanks to ICT. 9. Make Things Easier  Teachers may design interactive classrooms using ICT, which makes the lesson more fun. 10. GUI Enhance Learning  Images may be employed in education to enhance students' long-term memory using ICT. ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict  Advantages and Disadvantages of ICT DISADVANTAGES 1. Lack of Work Security  Because technology is constantly evolving, experts in various industries think that ICT has created job security a major problem. If people want to feel comfortable in their work, they must continually learn new things or be aware of developments in their field. 2. Cultures were becoming Dominant  Although ICT could have made the globe more interconnected, it has also led to one society absorbing a weaker one. For instance, it is currently said that American teens have an influence on how the majority of young teenagers throughout the world today act, dress, and behave. ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict  Advantages and Disadvantages of ICT DISADVANTAGES 3. Privacy  Information technology may have boosted, simplified, and improved communication, but it has also given rise to privacy concerns. People are increasingly concerned that their formerly private information may become public knowledge due to mobile phone signal interceptions and e-mail hacking. Apart from these issues, Computer worms, Trojan horses, malware, spam, and phishing are a few of the various threats that may ruin our daily lives. ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict  Advantages and Disadvantages of ICT DISADVANTAGES 4. Reliance on Technology  Professor Ian Robertson, a neuropsychology specialist at Trinity College Dublin who conducted the study, said: "People have a lot to remember nowadays, and they're dependent on technology for the memories, but the less you use of your memory, the weaker it becomes. Because they utilize a spell-checker or a calculator to complete simple addition or subtraction, many don't bother learning.” 5. Information Reliability  Just because something is online doesn't guarantee it is dependable. Anybody with computer and internet access can create a blog or post something on a website. The open-source encyclopedia Wikipedia is an excellent illustration of this because, although being a good source of knowledge, academic institutions do not accept it as a reliable source of references ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict  Advantages and Disadvantages of ICT DISADVANTAGES 6. Expensive  Too expensive to be able to afford. 7. Need Separate Training  Lack of experience makes it challenging for instructors to utilize ICT technologies. ce: https://www.javatpoint.com/advantages-and-disadvantages-of-ict Evolution of the WEB 1.
