A "computer" is, according to Wikipedia, "any machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming."There are many types and kinds of computers, but I usually focus on three types:
- Personal computers (PCs), including laptops and tablets that have typical PC traits.
- Smartphones, including tablets that have typical smartphone traits.
- Single-board computers (SBC), as interesting as PCs and smartphones combined.
