How many characters can a storage medium of 256 gb hold?

The number of characters a 256 GB storage medium can hold depends on the encoding used. For example, if we use UTF-8 encoding, which typically takes 1 to 4 bytes per character, a rough estimate would be around 256 billion bytes. This translates to approximately 256 billion characters if we consider an average of 1 byte per character, but the actual number may vary based on the specific characters stored. Thus, the range could be anywhere from about 64 billion to 256 billion characters, depending on the character set used.
