Storage
Storage allows the computer/us to keep work "permanently" unless we want to delete it.
Storage is Internal - hard disk (inside the tower, connected via the motherboard) or portable - flash stick/hard drive (outdated : CD/DVD)
Storage has a larger capacity than memory due to the fact that it has to store our apps/data.
Storage capacities:
Storage capacities:
Kilobyte - 1024 bytes
Megabyte - 1024 Kilobytes (KB)
Gigabyte - 1024 Megabytes (MB)
Terabyte - 1024 Gigabytes (GB)
Hard drive -usually large GB (250GB-2TB)
Flash drive - 1GB - 64GB
