A VPN extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels. An employee can work outside the office and still securely connect to the corporate network.
Scotland, in common with the rest of the UK uses Pound Sterling (GBP) divided into 100 pennies (or pence). Scotland uses banknotes issued by three different commercial banks;- Royal Bank of Scotland, Bank of Scotland and the Clydesdale Bank. Bank of England banknotes are rarely accepted in Scotland.
In N. Ireland its GBP (Sterling) as in Scotland but Scotland does have its own Â£5/Â£10/Â£20 etc. notes which are legal currency in England as well - though sometimes the English shopkeepers look at you strangely when you try to use them! We also still have Â£1 notes in circulation in Scotland although they are not used as much as Â£1 coins.
