Moving Files
mv command seems so basic, so straightforward.
Reminder: mv -b is useful for creating backups of any files that exist in the destination directory. If merging two big directories with some overlapping files, this is a useful option to be able to compare once everything is in the same place.

Hardware
A computer is hardware that runs software. These devices power the systems and applications we've come to rely on.
If you're just getting familiar with learning about computers, the Raspberry Pi ecosystem is a great place to start. Heavy overlap and an inexpensive entry point. Learning is part of the process.
Computers are defined by three general properties; how much: computational processing power (CPU), memory, and storage.
Storage
Memory and storage may seem like the same, but for now memory is a fast storage system that only exists while power is supplied. Storage is slightly slower for reading and writing, but the information persists after power is removed.
Operating Systems
Set up a computer with a fresh operating system.
Linux is common on desktop machines in the open source world. There are many flavors:
In the mobile phone space, Android is a good open source solution.
If you don't already have a preferred operating system, consider one that is open source.
Windows and Mac OS X are good options too.
Boot
The boot sequence gets the system started so it is ready to run software.
