ここ10年でずいぶん's meaning


コンピューターの技術は、ここ10年でずいぶんです。

What does ここ10年でずいぶんです mean.

ずいぶん means remarkable (I searched from a website),but I don't know what で
functions and what ここ10年 means.

In my opinion, I think it means "Computer technology will be remarkable in
this 10 years"




According to the comment, the correct sentence is:

> コンピューターの技術は、 **ここ10年で** ずいぶん **進んでいます** 。  
>  The computer technology **has advanced** greatly **in the last 10 years**.

Or:

> コンピューターの技術は、 **ここ10年で** ずいぶん **進みました** 。  
>  The computer technology **advanced** greatly **in the last 10 years**.

`ここ + time-length` is a way to say "last ～". For example ここ3日で is "in the last
three days". To say "next ～", you can use この先. For example この先3日で means "in
the next three days". This particle で is a equivalent of English "in" used
with a time frame.

This means the sentence is about the **past** 10 years, so you have to
conjugate 進む ("to advance") into either the -teiru form or the past (-ta)
form.
