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?
A2 to the power 10 ✓ Correct
B2 to the power 12
C2 to the power 22
D2 to the power 32
Correct answer: (A) 2 to the power 10 — The application can support 2 to the power 10 records, so the answer is 2 to the power 10.
Explanation
★The application can support 2 to the power 10 records, so the answer is 2 to the power 10.
★Each staff record is identified by a staff ID.
★The staff ID is stored using 10 bits.
★With n bits, the number of distinct values is 2 to the power n.
★So 10 bits give 2 to the power 10 distinct IDs.
★Each distinct ID can identify one staff record.
★So the application can support 2 to the power 10 staff records.
