I can do all parts of the IELTS test on the computer
This is true - but depends on the format you choose.
The Reading and Listening parts of the IELTS test are completed on a computer, and if you choose IELTS Writing on Computer as your Writing delivery format, your Writing test answers will be typed on computer, too.
The Speaking test remains as a conversation with an IELTS examiner.

The IELTS Writing on Computer test is different from the IELTS Writing on Paper test
This is a myth!
The only difference between the IELTS Writing on Computer and IELTS Writing on Paper test is the delivery format for the Writing section of the IELTS test.
If you choose to take IELTS Writing on Paper, you can handwrite your Writing answers on paper and take the Listening and Reading on computer.
If you choose to complete your IELTS Writing test on a computer, all answers for IELTS Writing will be typed on the screen.
The task types, scoring, & time allocation of the Writing section are the same whether you type on a computer or write on paper.
In both options, the Listening and Reading tests are taken on computer, and the Speaking test is conversation with an IELTS examiner.
