countable or uncountable

Hi, I have a question related to nouns.

If my PC receives (different) data twice, say, from a PC "A" and a PC "B",
could I write:

"There have been (two) data receptions from both a PC 'A' and a PC 'B'",

or

"There has been data reception from both a PC 'A' and a PC 'B'"?

Also, I understand the word "data" is uncountable, but when mentioning the above data, which one is correct,
"data of two different types" or "two different types of data"?

Thanks in advance:-)

Data is not always uncoutable; some use it as a plural, with datum as the singular. You will hear scientists and statisticians say 'these data are', though most people use it uncountably. I would say 'Data has been received from both PC A and PC B'. You could use both "data of two different types" and "two different types of data". However, are they different types of data or different sources?

Thank you for your reply.

Okay, so data could be both singular and plural, thanks.

I meant the data of the same source, like, one is encrypted, and the other is decrypted, or something like that.
I guess in that case you could say "data of two different types", no?

Thank you again.

In computing, I normally see it used as an uncountable noun. And the answer to your question is yes. ;-)
