Since computers were first invented they have been used for a variety of different reasons. Initially they were only for large organisations, multi-national companies and government departments. Bit by bit they filtered down into smaller companies, the education system and for personal use. Computers became smaller and also more sophisticated; able to carry out a much wider range of tasks, and as such there was a greater demand for them. Now most companies use them for at least one aspect of their business, and a large number of households have a computer and access to the internet for entertainment as well as functional reasons such as work and homework.
Unless someone works in a specialist area, it is unlikely that the average household needs a particularly elaborate computer; the main functions are office programs such as word processing and spread sheets, Internet access, using social media networks such as Facebook and Twitter, and email to keep in touch with others. This kind of computer is not overly expensive but they are still not a cheap piece of equipment and as such should be taken care of in the usual ways; used with care and protected from viruses with protection software.
Home computers can break no matter what you do but the relatively simple nature of them makes them easier to fix than a work system or network. There are a lot of shops, companies and individuals that carry out computer repairs London wide, and you will find that if it’s at all possible to repair it, this will be much cheaper than replacing it, with the level of function that you need for an average household computer. Those carrying out computer repairs London wide will either work from a shop that you can leave it at or if you are home based, they can come to you. The more local that the company is the less expensive it is likely to be.
