✍️ Sample NOCTI Questions & Answers
1. What is the difference between RAM and ROM in a computer system?
RAM (Random Access Memory) is volatile and loses all stored data when power is removed. ROM (Read-Only Memory) is non-volatile and retains its data permanently, typically storing firmware and boot instructions.
2. The PCI Express bus currently comes in how many different slot sizes?
The PCI Express bus currently comes in four different slot sizes. This means that there are four different physical sizes of slots available for PCI Express devices to be inserted into a computer's motherboard. These different slot sizes allow for flexibility in terms of the types of devices that can be connected to the PCI Express bus, accommodating various sizes and configurations of expansion cards.
3. What type of saw is best suited for making curved cuts in wood?
A jigsaw uses a thin, reciprocating blade that can follow curved patterns, making it ideal for cutting curves and irregular shapes.
4. How many bits are in the SIMMs data path?
SIMM stands for Single In-Line Memory Module, which is a type of computer memory module. The data path refers to the width of the memory bus, which determines the amount of data that can be transferred between the memory module and the processor in a single clock cycle. In this case, the correct answer is 32, indicating that the SIMMs data path is 32 bits wide. This means that it can transfer 32 bits of data at a time, allowing for faster data transfer and processing.
5. What is the difference between deductive and inductive reasoning?
Deductive reasoning starts with general principles and draws specific conclusions (top-down), while inductive reasoning starts with specific observations and develops general conclusions (bottom-up).
6. What is the primary function of the alternator in an automotive electrical system?
The alternator is driven by the engine and uses electromagnetic induction to produce AC electricity, which is rectified to DC to recharge the battery and power vehicle systems.
