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.
Pounds are coins. They are the same in England and Scotland. Anything bigger comes in paper notes. ( Â£5, Â£10, Â£20) These differ between the two places, but don't stress about it. Any notes from England can be used in Scotland with absolutely NO problem.
