A new study from Plusnet has revealed many UK broadband customers are unsure of internet-related terminology.
The Sheffield-based broadband provider found that despite 59 per cent of survey respondents owning an internet-enabled PC, 26 per cent struggle to understand computer jargon.
Among the terms causing consumers difficulty are bandwidth, Wi-Fi, cursor, router and download.
The Plusnet study also indicated that older people are more clued-up about broadband and computing than younger generations think.
"It was those over 55 who scored well with jargon-busting, as a healthy 72 per cent claim they understand all of the terms perfectly compared to only 61 per cent of those aged between 16 and 24," Plusnet's Bob Pullen stated.
He claimed the findings were "particularly poignant" this Christmas given the explosion in personal computing.
Mr Pullen said many people are hoping to find a new tablet, smartphone or notebook computer under the tree on Christmas morning.
But whether or not they understand everything in the instruction manual is in doubt.
