Software products or other informatic, electronic or mechanical goods. In general, technical support services address specific problems with a product or service rather than the provision of training, customization, or other support services. Most companies offer technical support for the products they sell, either freely available or for a fee. Technical support may be delivered over by e-mail, live support software on a website, or a tool where users can log a call or incident. Larger organizations frequently have internal technical support available to their staff for computer-related problems. The Internet can also be a good source for freely available tech support, where experienced users help users find solutions to their problems.
