The computer still sits at the centre of many people's lives. Fitting it in and around the multitude of other devices (smartphones, tablets, bluetooth connections, music and TV servers) makes it all the more important to know how to manage your computer. This straightforward new book helps answer those awkward questions -- why is my computer so slow?, How do I set up wi-fi in my home? -- and covers other essential tasks such as backing up, checking for viruses and dealing with child-protection measures.
