Step 1 A good tech not only will learn the specifications of different CPU chips, but also will master the use of reference tools such as the Internet, manufacturers' Web sites, product documentation, and reference books. A quick search of the Web or your motherboard manual will generally yield a full list of specs for a given CPU. In the following table, see how many CPU chip features you can fill in given the maker and CPU type. Keep in mind that CPUs have very short production lives. If some of these CPUs have become obsolete, use the extra rows provided to add more modern processors to the assignment.
