Overall, your answers seem to be mostly correct. However, there are a couple of corrections that can be made for a more accurate assignment. Here is the corrected list:

1) bar code reader (a)
The purpose of a bar code reader is to read and extract information from source documents, such as barcodes on product packaging. It is used to input data into the accounting system. Therefore, it should be assigned to "source documents" (a), rather than "input devices" (b).

2) filing cabinet (d)
A filing cabinet is used to store physical documents, such as invoices, receipts, and other relevant paperwork. It is used to store information, making it suitable to be assigned to "information storage" (d).

6) zip drive (d)
A zip drive is a form of external storage device used to store computer files. It is primarily used for information storage, rather than information processing. Therefore, it should be assigned to "information storage" (d), instead of "information process" (c).

11) digital camera (a)
A digital camera is often used to capture source documents, such as receipts or other important records. It plays a role in providing source documents for the accounting system, so it should be assigned to "source documents" (a).

Apart from those corrections, the rest of your answers are accurate:

4) computer scanner (a)
5) computer keyboard (b)
7) computer monitor (e)
8) invoice from a supplier (a)
9) computer software (c)
10) computer printer (e)
12) mp3 player (d)

Remember, when assigning the roles, think about how each device or document fits into the accounting system's processes, such as collecting and recording data (source documents - a), inputting data (input devices - b), manipulating and analyzing data (information process - c), storing data (information storage - d), and presenting data (output devices - e).
