It reduces your dependence on help desks, technical support lines and so-called gurus whenever anything goes awry. What you buy depends on what you need. The subject matters range from basic lessons on how to use a PC to the latest programming and networking tools. The types of training range from impersonal tape recordings to teachers who hold classes in your office.

Tapes can be purchased or rented and watched whenever convenient.
