The correct answer is C. The wider the data bus, the greater the computer’s processing speed.
A data bus is a set of wires that carries data between the CPU and other parts of the computer. The wider the data bus, the more data can be transferred at once. This means that the CPU can access data more quickly, which can lead to faster processing speeds.
Option A is incorrect because the narrower the data bus, the slower the computer’s processing speed.
Option B is incorrect because the width of the data bus does not affect the amount of data that can fit into main memory. The amount of data that can fit into main memory is determined by the size of the memory chips.
Option D is incorrect because the wider the data bus, the faster the computer’s processing speed.
Option E is incorrect because the data bus is important to the processing speed of a computer.
