Download Solution PDFThe 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.
