Answer Details

(a)

1. (i) Disk formatting: Disk formatting is the process of preparing a storage device, such as a hard drive, for use by organizing it into sections called partitions and setting up a file system on it to manage the data stored on the device. This process erases all the data on the disk and makes it ready for use.

2. (ii) Data backup: Data backup is the process of creating a copy of important data and storing it separately from the original data, typically in a different location or on a different storage device. The purpose of data backup is to have a copy of the data that can be used to restore the original data in the event of data loss, such as due to hardware failure or data corruption.

3. (iii) Virus scan: Virus scan is the process of checking a computer or device for malicious software, commonly known as viruses, and removing them if found. This process is typically performed using antivirus software and is an important step in protecting a computer from potential harm.

(b)

1. (i) Withdraw cash: One of the main uses of ATMs is to withdraw cash. Customers can use their debit or credit cards to withdraw money from their bank accounts at ATMs.

2. (ii) Check account balance: Another use of ATMs is to check the balance of a customer's bank account. Customers can use their debit or credit cards to access their account information and see how much money they have in their account.

3. (iii) Transfer funds: ATMs also allow customers to transfer funds between their accounts. For example, a customer can transfer money from their savings account to their checking account.

4. (iv) Pay bills: Some ATMs also allow customers to pay their bills. Customers can use their debit or credit cards to make payments on their utility bills, credit card bills, and other types of bills.
