Select the TRUE statement from the following.
Show answer & explanation
Answer: B. Integration of processing power on chips has made processing power cheaper.
Option B is factually correct: Moore's Law and semiconductor integration have dramatically reduced the cost per transistor and per unit of processing power over decades. Options A, C, and D are false: A conflates distinct architectures (microprocessors vs. systems-on-chip), C is historically inaccurate (CPUs predating microprocessors used discrete components and SSI/MSI ICs), and D ignores resistors, capacitors, diodes, and other circuit elements present in microprocessor designs.
Step-by-step Derivation:
Evaluate each statement:
- A) False. A microprocessor is a single processing unit; a computer-on-chip (SoC) integrates multiple functional units (CPU, memory, I/O). Related but not 'variations of each other.'
- B) TRUE. Historical fact: integration and miniaturization have continuously reduced cost-per-MIPS and cost-per-transistor.
- C) False. Pre-microprocessor CPUs (1950s–1960s) used discrete transistors and small-scale ICs (SSI), then MSI chips. The statement contradicts history.
- D) False. Microprocessors contain transistors as the primary active elements, but also include passive components (resistors, capacitors), diodes, interconnects, and other circuit elements in their physical layout.
