Around three quarters of adults in the UK have experience of using a computer, making the country a nation of computer buffs, according to a survey published on Sunday by industry association, the British Computer Society.

The survey of 2,180 adults was designed to assess the level of IT literacy among the British public, and found that 80% of us now believe that computers have made a positive contribution to our lives.

Market research firm TNS, which carried out the survey, found that 73% of respondents using a computer did so in order to surf the internet, while 57% used the internet to purchase goods and services. This, according to the BCS, shows that spam, computer viruses and on-line fraud are not damaging the computer's image too much, but that there is in fact a growing confidence in shopping on-line.

Concerns that computer users spend hours glued to their PC screens were also dispelled: only 34% of those questioned use their PC for more than five hours a week, although 12% spend over 30 hours per week in front of their computer.

David Clarke, BCS chief executive, attributed the upsurge in the nation's computing confidence to a growing social focus on the importance of computer literacy, backed by the upsurge in available IT training from employers.

However, the report also highlighted the significant proportion of adults who are in danger of being marginalised as the government gears society up for the information age. Although 59% of respondents have a home PC, the survey found that 26% have no access to a PC whatsoever, whether at home, work, college or a public library, suggesting the IT revolution is in danger of leaving behind a quarter of the population.

"It is clear that not everyone is experiencing the benefits of computing, despite the government's aim to ensure every home has access to a PC. This is an area which must be addressed," warned David Clarke.

"We see it as essential that all of society is able to use a computer with the same confidence as the telephone," he added.

The report also found that 54% of respondents were frustrated by the complexity of IT, while 72% were concerned about the immoral content to be found on the internet.

Concerns over unsuitable internet material were highlighted in another survey, published by IT consultancy Detica late last month. That survey of 1,006 UK adults, conducted by MORI, found that 37% of respondents were so concerned about accidentally accessing porn and adult material via the internet that they feared they could be prosecuted or lose their jobs as a result.
