The tech sector is best understood by breaking it into its distinct sub-sectors, each with a different business model.
- Software: Develops and sells intellectual property in the form of code. Includes enterprise software (Oracle, SAP), operating systems (Microsoft), and cloud-based Software-as-a-Service (SaaS) (Salesforce). Typically features high gross margins and recurring revenue.
- Hardware: Produces physical equipment. Includes personal computers (HP, Dell), mobile devices (Apple), servers, and networking gear (Cisco). Also includes the highly specialized and cyclical semiconductor industry (NVIDIA, Intel).
- IT Services: Provides consulting, systems integration, and outsourcing services. Includes global players like Accenture and IBM. A more labor-intensive, lower-margin business than software.
- Internet & E-commerce: Includes search engines (Google), social media (Meta), and online retail (Amazon). Business models are often based on advertising or transaction fees.
