Data representation is based on the _______ number system, which uses two numbers to represent all data
Data representation is based on the byte number system, which uses two numbers to represent all data.
Each hexadecimal digit represents four binary digits, and thus is used in computing to abstract four bits to a single unit - the hex digit. For example, byte values can range from 0 to 255 (decimal), but may be more conveniently represented as two hexadecimal digits in the range 00 to FF.
Data Representation. ... Each individual 1 or 0 is called a binary digit or bit and it is the smallest piece of data that a computer system can work with. Eight bits are grouped together to make one byte. One byte provides enough codes (256) to represent all of the characters that appear on a standard keyboard.
