Rearrange the following sentences to form a coherent paragraph:
1. The most critical component is the central processing unit (CPU), which acts as the "brain" of the machine.
2. The architecture of a modern computer is a complex arrangement of various hardware and software components.
3. This complex interplay of components allows the computer to execute a wide range of tasks, from simple calculations to complex simulations.
4. The CPU works in tandem with memory, storage devices, and input/output peripherals to process data.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2, 1, 4, 3.
Logical flow:
2: This is the opening sentence—it introduces the overall topic: computer architecture.
1: After introducing the system, it logically moves to its most important component—the CPU.
4: This follows naturally by explaining how the CPU interacts with other components.
3: This acts as a concluding sentence, summarizing the overall functioning and outcome of this interaction.
Thus, the correct sequence becomes: 2 → 1 → 4 → 3
Final Paragraph:
The architecture of a modern computer is a complex arrangement of various hardware and software components. The most critical component is the central processing unit (CPU), which acts as the "brain" of the machine. The CPU works in tandem with memory, storage devices, and input/output peripherals to process data. This complex interplay of components allows the computer to execute a wide range of tasks, from simple calculations to complex simulations.
