Information systems hardware consists of the components of digital technology that you can touch. In this chapter, we focused on the personal computer and its components. We reviewed the personal computer configuration because it has many of the same attributes as other digital computing devices. A personal computer comprises many components, most importantly the CPU, motherboard, RAM, hard disk, removable media, and input/output devices. We also reviewed some personal computer variations, such as the tablet computer, Bluetooth, and the smartphone. By Moore’s Law, these technologies have improved quickly over the years, making today’s computing devices much more powerful than devices just a few years ago. Finally, we discussed two of the consequences of this evolution: the commoditization of the personal computer and the problem of electronic waste.
