High I/O graph

[techyOmen]

My site - techdecypher.ml

My daily I/O graph is almost at the limit . The question is what is I/O graph . I tried to find what is daily i/o in infinityfree knowledge base . But i couldnt understand what it is . Can anyone explain in a simple way what cases my I/o graph to go up ( and it is almost at the verge of hitting the limit ) .
Is it that due to visitor or due to constant changes in my site or something else ?

Does something like this help?

Suspended account for IO limit

IO limits are tracked based on your interactions with the server storage. So actions which read or write a lot of data to or from the storage generate IO usage. Those activities include importing data, creating backups, running exports and installing and removing scripts and plugins. It does not include: Anything that does not involve your website itself, like email on your domain. FTP traffic. Database traffic. Installations with Softaculous. Yes, if you hit the daily limit too many times…
