0s and 1s (data storage)
To process and store data, digital devices use electrical circuits with two states (0=closed 1=open).
In computing, these two states represent bits.
8 bits (e.g. 10010011) = 1 byte = 1 character (approximately)
Question 1:
What is the number of bytes and bits in the word dog?
Question 2:
An old computer has 256 MB (megabytes) of RAM. Approximately how many characters can it store?
The M stands for 1,000,000.
The B stands for byte.
Question 3:
A more recent computer has a 512 GB (gigabytes) hard drive. Approximately how many characters can it store?
The G stands for 1,000,000,000 .
The B stands for byte.
Question 4:
An even newer computer has a 4 TB (terabytes) hard disk: approximately how many characters can it store?
The T stands for 1,000,000,000,000.
The B stands for byte.
The byte, Wikipedia's view
1 kilobyte (kb)= 103 bytes= 1,000 bytes
1 megabyte (MB)= 106 bytes= 1,000 KB= 1,000,000 bytes
1 gigabyte (GB)= 109 bytes= 1,000 MB= 1,000,000,000 bytes
1 terabyte (To)= 1012 bytes= 1,000 GB= 1,000,000,000 bytes
1 petabyte (Po)= 1015 bytes= 1,000 To= 1,000,000,000,000 bytes
1 exabyte (Eo)= 1018 bytes= 1 000 Po= 1 000 000 000 000 000 000 bytes
1 zettabyte (Zo)= 1021 bytes= 1,000 Eo= 1,000,000,000,000,000,000 bytes
1 yottabyte (Yo)= 1024 bytes= 1 000 Zo= 1 000 000 000 000 000 000 000 000 bytes
