Hardware Basics

Understanding what hardware we use, whether it's directly or indirectly via a Cloud provider, is important because ultimately everything we're doing in this field involves getting computer hardware to do something for us.

This is what Wikipedia says about computer hardware:

Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. - https://en.wikipedia.org/wiki/Computer_hardware

The hardware basics I recommend you get a good understanding of includes:

  • The Central Processing Unit, or CPU
  • Random-access Memory, or RAM
  • Hard Disk Drive, or HDD
  • Solid State Drive, or SSD
  • Network Interface Controller, or NIC
  • Graphics Processing Unit, or GPU

Those are the components that make up the physical and even the virtual infrastructure you will encounter in your career.

There is networking hardware to understand too. There are two pieces of networking hardware I recommend you understand well: the switch and the router.
