Parents assume children understand technology acronyms Almost half could define CPU as Central Processing Unit and 87 per cent were able to explain WiFi. The survey suggested that children may not be far behind, with 48 per cent of children aged 12 or under believed to be able to identify RAM. Less than a third are believed to be able to identify CPU and 84 per cent were thought to know what WiFi meant. Mant parents admitted to asking their children for technology advice, with 64 per cent admitting they would go to their children with a tech problem, as the child is likely to understand it better than they do. "Adults aren't just lacking confidence in their technology acronyms, many also lack knowledge about the simplest of tasks, such as upgrading their computer, which could help it run quicker and more efficiently," said Roddy McLean, computer upgrade specialist from Crucial.com. Asking children for their help with technology could be easily avoided if adults realised just how easy technology DIY upgrades can be.
