Bytes
Depends on how many bytes it has
Bytes
640 x 1024 x 1024 bytes (data transfer) 640 x 1000 x 1000 bytes (storage)
1,000,000,000,000,000,000 bytes or 1018 bytes
A bit is a single 1 or 0. A Byte is 8 bits.
Storage is measured in a hierarchy of bytes.
mega byte
KB refers to kilobyte which is a unit of computer storage equal to 1,024 bytes. MB refers to megabyte which is a unit of computer storage equal to 1,048,576 bytes. 30MB equals 30,720KB.
The storage size of an int in C is loosely defined, and may be either 2 bytes or, more commonly, 4 bytes. Whether or not it is defined as const won't affect the size.
It is the memory capacity of the storage unit.
