What is the full form of 'RAM'?
-
Read-only memory
-
Random access memory
-
Read access memory
-
None of the above
Correct Answer
A. Random access memoryExplanation
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.Rate this question:

Which type of memory is non-volatile and used to store firmware?
-
RAM
-
ROM
-
Cache
-
SSD
Correct Answer
A. ROMExplanation
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.Rate this question:

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.Rate this question:

Which part of the computer is the brain of the computer?
-
Monitor
-
Keyboard
-
CPU
-
None of the above
Correct Answer
A. CPUExplanation
The correct answer is the Central Processing Unit (CPU). The CPU is often referred to as the brain of the computer because it is responsible for executing instructions and performing calculations. It controls the operations of all the other hardware components and manages the flow of data within the computer system. The CPU contains the arithmetic logic unit (ALU) which performs mathematical and logical operations, and the control unit which coordinates and controls the activities of the computer. Without the CPU, the computer would not be able to process and execute instructions, making it an essential component for the computer's functioning.Rate this question:
