Digital World 2017, an exposition promoting the country's information technology sector, drew huge crowd on Friday, a weekly holiday.
Tech-lovers, especially youths, along with their close ones started gathering at the city's Bangabandhu International Conference Centre (BICC) since the morning to know about the latest developments in the ICT.
Visitors were seen waiting in a long queue for nearly an hour to enter the fair venue.
Abdul Halim Forhad, a private service-holder who came to the expo with his family, said he came here to know about local startups taking part in the fair.
"I think the country has been making a significant progress in the ICT in recent years," he said adding that: "I believe our local tech companies will be famous as like as Google, Facebook and Uber."
Mr Halim also said he wanted to see social robot 'Sophia' at the inaugural ceremony. "But I couldn't visit the fair on Wednesday when I went to my office. I took this opportunity today (Friday)," he said.
Prime Minister Sheikh Hasina on Wednesday afternoon inaugurated the four-day fair as the chief guest.
A humanoid social robot with artificial intelligence named Sophia was presented at the inaugural ceremony. Her (Sophia) conversation with the prime minister created a buzz of tech-lovers. Though Sophia left the country on Wednesday, tech-savvies are coming to the fair to meet new technologies.
Information Communication and Technology (ICT) division has organised Digital World (DW) with support from various government and non-governmental organisations including Bangladesh Computer Council (BCC), Bangladesh Association of Software and Information Services (BASIS) and Access to Information Program (a2iProgram) under the Prime Minister's Office.
