__23. A bit isa) a single 0 or 1 in the binary code.b) equal to 64K of RAM.c) a group of eight 0s or 1s in the binary code.d) a person’s name stored in memory.

Question Analysis

The question asks for the definition of a "bit," which is fundamental in the field of computing and digital electronics.

Relevant Concepts

A bit (short for "binary digit") is the most basic unit of data in computing and digital communications. It represents a state of either 0 or 1 in binary code.

Options Analysis

1. Option a: "a single 0 or 1 in the binary code."

   • This accurately describes a bit.

2. Option b: "equal to 64K of RAM."

   • This is incorrect, as 64K of RAM refers to 64 kilobytes, which is substantially larger than a single bit.

3. Option c: "a group of eight 0s or 1s in the binary code."

   • This describes a byte, not a bit.

4. Option d: "a person’s name stored in memory."

   • This is unrelated to the definition of a bit.

Conclusion

Based on the analysis of the options, the correct answer is option a, as it correctly identifies a bit as "a single 0 or 1 in the binary code."

Final Answer

a) a single 0 or 1 in the binary code.
