Final answer:
option a,The four different possibilities for extension digit length in a computer system are 8-bit, 16-bit, 32-bit, and 64-bit. These terms refer to the number of bits used to represent data in a computer system.
Step-by-step explanation:
The four different possibilities for extension digit length in a computer system are:
- 8-bit
- 16-bit
- 32-bit
- 64-bit
These terms refer to the number of bits used to represent data in a computer system. For example, an 8-bit system can represent 2^8 (256) different values, while a 16-bit system can represent 2^16 (65,536) different values.
The question refers to the extension digit length in a computer system, which is a measure of computational capacity, memory, or data width relating to processors and data storage. The extension digit length commonly referred to as 'bit' size, indicates the number of binary digits (bits) that a system can process or represent at once. The four different possibilities for extension digit length in a computer system are 8-bit, 16-bit, 32-bit, and 64-bit. These bit sizes are integral for understanding the processing power and memory capacity of computers. Additionally, in relation to computer memory units, the term for one million bytes is a megabyte (MB).
