  • Public Cloud

Social and Economic Impact of ICT

ICT has had a large social and economic impact on society, as it has changed the way people communicate, learn, work, and live. Additionally, ICT has contributed to converting human experience into the computer. Therefore, today, robots can perform most human tasks and handle them efficiently.

ICT has largely contributed to the growth and development of the business and economy. The digital age is possible only because of ICT, and it has converted the traditional face to face interactions to digital ones.

Despite the tremendous possibilities and opportunities of ICT, the distribution of its capabilities is not even among the people. Rich countries and individuals have access to explore more possibilities of ICT. For example, many people have access to the devices such as smartphones, tablets, and laptops. However, internet access is limited to people that can afford it. Even if many can afford the internet, they still have limitations of speed.

Advantages and Disadvantages of ICT


The developments in the ICT have led to many cost-saving opportunities for businesses. These include businesses ranging from small scale to large scale. ICT has also changed the way people shop, socialize, communicate, and interact. It has given more choices to people and also enabled internet shopping by facilitating online transactions. Engineers at ICT are developing various applications and systems to make work and daily life easier for everyone.


ICT has several advantages that have contributed to the growth and development of society. However, many problems have arisen with the development of ICT. Data security is one of the major problems.
