The Fine Print
Jobs within these businesses aren't all technical; they include administrative, marketing, sales and support positions. But the bulk of the jobs in each sector are technical.
Because large IT companies could employ workers in several sectors, their employment could be scattered among different categories, based on individual worksites. For example, IBM employees designing, manufacturing and selling eServers would be grouped within the Computer and Peripheral Manufacturers category, while those employed by the unit that creates and supports WebSphere middleware would be placed within the Software Publishers group.
