Computers and IT (Information Technology) in general are a very big part of a lot of business in today's world, they are used all of the country and worldwide for a number of different purposes. As with all technology they carry the risk of going wrong and not only that but some people simply find them hard to use and do not understand their operation.
To some people a computer can be a daunting prospect and to others the operation of them can come second nature. However if you fall in to the category of maybe needing a little help then there are a lot of companies out there that can offer you help. Often they are support lines, you call the company up and an operator will pick up, from here you explain your problem to them or what you need help with. Some companies will try and help you from this point, but larger support companies will often work out which department you need (from what you told them) and transfer you through.
More than often they will be able to help you there on the spot, they will explain what you have to do and run through it with you on the phone while you do what they tell you. In the odd case the problem can not be solved some companies will be able to send out a technician to help you.
Be warned, these businesses operate a premium rate phone line, make sure you check how much the call will cost you per minute before calling.
