One terabyte is equal to 1,099,511,627,776 bytes; 1 byte is equal to 8 bits. Terabytes and bytes are often abbreviated as TB and B, respectively. Both of these terms are used to measure data volume for computers and other digital information systems.
A flash drive can hold 1 terabyte of data, although storage sizes vary. A byte contains the smallest amount of bits that can be utilized by most computers and computer systems. Bits, expressed as either 1 or 0, are the smallest and most basic units of digital technology data. The 8 bits that make up 1 byte can be expressed in different combinations to create 256 codes.
