Concept:All instructions and data in a digital computer are stored as binary digits, or bits, which are the most basic unit of digital information.
Explanation:A digital computer can only understand two distinct states, usually written as
0 and
1.
Each single
0 or
1 is called a bit.
Bits are grouped together to form bytes, and these combinations are used to represent numbers, letters, symbols, and even machine instructions.
For example, the character "A" can be represented by the bit pattern
01000001, and the digit "
1" can be represented as
00000001.
Even though alphabets, numerals, and characters appear as human-readable forms, the computer actually stores them as patterns of bits.
Instructions, such as adding numbers or printing a message, are also translated into bit patterns that the processor understands.
Thus, bits are the foundation of every piece of stored data and every instruction in a computer system.
Answer:Stored instructions and data in a digital computer consist of bits.
Correct option:
A. bits.
