Aman installs a web camera in the waiting area of a clinic for security purposes and finds that a 1- minute video takes up approximately 10 MB. Which of the following is the required storage capacity of a daily backup in GB (correct to three significant figures)?

The correct answer is - 14.1 GB

Key Points

• Video Storage Calculation
  • Each 1-minute video takes up 10 MB.
  • There are 60 minutes in an hour and 24 hours in a day.
• Total Minutes per Day
  • Total minutes in a day = 24 hours/day * 60 minutes/hour = 1440 minutes/day.
• Total Storage per Day
  • Total storage required = 1440 minutes/day * 10 MB/minute = 14400 MB/day.
• Conversion to Gigabytes
  • 1 GB = 1024 MB.
  • Total storage required in GB = 14400 MB / 1024 MB/GB = 14.0625 GB.
  • Rounded to three significant figures, the required storage capacity is 14.1 GB.

Additional Information

• Data Storage Units
  • 1 Kilobyte (KB) = 1024 bytes
  • 1 Megabyte (MB) = 1024 KB
  • 1 Gigabyte (GB) = 1024 MB
  • 1 Terabyte (TB) = 1024 GB
• Importance of Backup
  • Regular backups ensure data security and availability in case of system failures.
  • For security purposes, video surveillance data is crucial and needs to be backed up daily.
