An Indian company designs a mobile application to process staff records. In each record, 10 bits are used to store the staff ID and 20 bytes are used to store the staff name. How many staff records can the mobile application support?

With 10 bits reserved for the staff ID, the app can uniquely number 2 to the power 10 records.

Each distinct ID marks one record, and 10 bits give 1024 combinations.

The 20 bytes hold the name and do not limit how many records there are.

2 to the power 12 would need 12 identifier bits.

2 to the power 22 or 32 far exceed what 10 bits can address.

The identifier width, not the name field, caps the record count.
