Understanding Computer Memory Organization

What is the primary function of computer memory?

• To provide power to the computer components.

• To increase the processing speed of the CPU.

• To connect the computer to the internet.

• The primary function of computer memory is to store data and instructions for quick access by the CPU.

Define RAM and its role in a computer system.

• RAM is a permanent storage device that retains data even when the power is off.

• RAM (Random Access Memory) is a volatile memory that temporarily stores data and machine code for quick access by the CPU, enhancing system performance.

• RAM stands for Read Access Memory and is used for long-term data storage.

• RAM is a type of software that manages hardware resources in a computer.

What is the difference between volatile and non-volatile memory?

• Volatile memory loses data without power; non-volatile memory retains data without power.

• Volatile memory is used for long-term storage while non-volatile is for temporary storage.

• Non-volatile memory requires constant power to retain data.

• Volatile memory is faster than non-volatile memory.

Explain the concept of cache memory.

• Cache memory is a permanent storage solution for all data.

• Cache memory is used exclusively for video processing tasks.

• Cache memory is a type of RAM that stores all system files.

• Cache memory is a high-speed storage area that temporarily holds frequently accessed data and instructions to speed up processing.

What are the different types of RAM?

• Cache Memory, Hard Disk, SSD

• The different types of RAM include DRAM, SRAM, SDRAM, DDR SDRAM, VRAM, and Flash RAM.

• ROM, PROM, EPROM

• Registers, Buffers, Pipelines

Describe the purpose of ROM in a computer.

• To increase the computer's processing speed.

• To provide a user interface for applications.

• The purpose of ROM in a computer is to store firmware and essential instructions for booting and hardware initialization.

• To store temporary data during operations.

How does virtual memory work?

• Virtual memory increases the speed of the CPU by adding more cores.

• Virtual memory is a type of physical memory that is faster than RAM.

• Virtual memory prevents applications from crashing by limiting their resource usage.

• Virtual memory allows a computer to use hard drive space as additional RAM, enabling it to run larger applications than the available physical memory.

What is the significance of memory hierarchy?

• It increases the cost of data access.

• It optimizes performance by balancing speed and cost in data access.

• It eliminates the need for caching.

• It reduces the speed of data retrieval.

Explain the term 'memory address'.

• A memory address is a type of computer virus.

• A memory address refers to the speed of the CPU.

• A memory address is a physical component of the computer hardware.

• A memory address is a unique identifier for a specific location in computer memory.

What is the role of the memory controller?

• The memory controller manages data flow between the CPU and memory.

• The memory controller stores data permanently.

• The memory controller is responsible for executing CPU instructions.

• The memory controller manages power supply to the CPU.
