The boss of networking giant Cisco has said the shortage of computer chips is set to last for most of this year.
Many firms have seen production delayed because of a lack of semiconductors, triggered by the Covid pandemic and exacerbated by other factors.Cisco chief Chuck Robbins said "The providers are building out more capacity. And that'll get better and better over the next 12 to 18 months."
That expansion of capacity will be crucial as advances in technology - including 5G, cloud computing, the internet of things and artificial intelligence - drive a big increase in demand.
Mr Robbins is the latest tech boss to weigh in on the debate - and with 85% of internet traffic using Cisco's systems, his opinion matters.
