MCQ
Q.
In computers, chip is made up of:
Correct Answer: B
The correct answer is A thin layer of silicon.
Key Points
- In computers, the chip is made up of a thin layer of silicon.
- Computer chips are made of silicon, which is a semiconductor, and in order to make the most efficient use of it, chip manufacturers use sand that contains as much silicon as possible.
- The mineral quartz is ideal for this purpose because its two main components are silicon and oxygen.
- Silicon is used because it can be used as either an insulator (doesn't allow electricity to flow) or a semiconductor (allows a little flow of electricity).
- This is important for making chips.
- It is very, very cheap.
- Hence, option 2 is correct.
Additional Information
- Silicon is used for electronic devices because it is an element with very special properties.
- One of its most important properties is that it is a semiconductor.
- This means that it conducts electricity under some conditions and acts as an insulator under others.
- It is even the most common element in the Earth's crust.
- Lady Ada Lovelace invented looping in computer programming.
- Lady Ada Lovelace wrote a complete plan describing the algorithm needed to calculate the Bernoulli numbers using two loops, demonstrating the bifurcation capabilities of the analytical machine, describing how to perform trigonometric operations that made use of variables.
