Understanding File Size Calculations

What is the fundamental rule for calculating file sizes?

• Add all values including metadata

• Divide all values by the number of files

• Subtract metadata from the total size

• Multiply all values except metadata

How many bits are used to calculate the size of a text file with 20 characters, each character being 32 bits?

• 1024 bits

• 640 bits

• 512 bits

• 320 bits

What is the first step in converting the calculated bits of an image file to bytes?

• Multiply by 8

• Divide by 8

• Add metadata

• Subtract metadata

How many bytes of metadata are added to the image file size calculation?

• 6 bytes

• 8 bytes

• 4 bytes

• 2 bytes

What is the total size in bytes of an image file before adding metadata if the calculated size is 960 bits?
