7. What is the full form of 'RAM'?
Answer:  Random access memory
Explanation:

RAM stands for Random Access Memory. It is a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is used by the operating system, software applications, and data in current use so that the CPU can quickly access them. This is essential for the system's speed because it allows for quick read and write access times compared to other kinds of storage like hard drives or SSDs. The term does not stand for Read-only Memory or Read Access Memory, making "Random Access Memory" the correct answer.

8. What component in a computer converts AC power from the wall outlet into the DC power required by the computer's internal components?
Answer:  Power Supply Unit (PSU)
Explanation:

The Power Supply Unit (PSU) in a computer is responsible for converting AC (Alternating Current) power from the wall outlet into DC (Direct Current) power that is required by the computer's internal components. The PSU is a crucial part of a computer because it ensures that all components, such as the motherboard, CPU, and graphics card, receive the correct voltage and current needed for safe and effective operation. The motherboard, heat sink, and network interface card (NIC) do not perform this function. The motherboard distributes power and data, the heat sink dissipates heat, and the NIC provides network connectivity. Therefore, the correct answer is "Power Supply Unit (PSU)."

9. Which type of memory is non-volatile and used to store firmware?
Answer:  ROM
Explanation:

ROM, or Read-Only Memory, is a type of non-volatile memory used to store firmware. Firmware is a specific class of computer software that provides low-level control for a device's specific hardware. ROM retains its data even when the computer is turned off, making it ideal for storing software that is rarely changed throughout the life of the system, such as the system's BIOS or firmware. Unlike RAM, which is volatile and used for temporary data storage, ROM ensures that essential software is permanently available. SSDs are also non-volatile but are used more commonly for general storage rather than firmware. Cache memory is fast and volatile, used for speeding up access to data and instructions by the CPU.

10. Which component of a computer is primarily responsible for managing and coordinating the communication between the CPU, RAM, and other hardware?
Answer:  Northbridge
Explanation:

The Northbridge is a component of a computer's chipset that is primarily responsible for managing and coordinating the communication between the CPU, RAM, and other high-speed hardware components like the graphics card. It acts as a bridge between these components, allowing them to communicate efficiently and effectively. The Northbridge plays a crucial role in a computer's performance because it handles data flows between the processor and the memory, as well as other peripherals. The Southbridge deals with lower-speed peripherals, the GPU handles graphics processing, and the BIOS is a type of firmware used for hardware initialization during the booting process and not for managing communication between components. Therefore, "Northbridge" is the correct answer.

11. Which of the following technologies is primarily associated with enabling low-latency, high-speed communication in autonomous vehicles?
