Understanding Memory and Storage

What are the main types of RAM?

• Read-Only Memory (ROM)

• Flash Memory (NAND)

• Cache Memory (CM)

• Dynamic RAM (DRAM), Static RAM (SRAM), Synchronous DRAM (SDRAM), Double Data Rate SDRAM (DDR SDRAM)

What is the difference between SRAM and DRAM?

• DRAM is faster and more expensive than SRAM.

• SRAM is faster and more expensive, while DRAM is slower and cheaper.

• SRAM and DRAM have the same speed and cost.

• SRAM is slower and cheaper than DRAM.

What does ROM stand for and what are its types?

• ROM stands for Read-Only Memory and its types include PROM, EPROM, and EEPROM.

• ROM stands for Read-Only Module

• Types of ROM include RAM, Cache, and SSD

• ROM stands for Random-Only Memory

What are the characteristics of PROM?

• Faster access than traditional hard drives

• Dynamic data structure that changes after programming

• Characteristics of PROM include non-volatile storage, one-time programmability, fixed data structure after programming, and slower access compared to RAM.

• Volatile storage with multiple programmability

Explain the concept of memory hierarchy.

• Memory hierarchy is a structured arrangement of various memory types in a computer system, optimizing speed and cost.

• Memory hierarchy is the process of deleting unused files from a computer.

• Memory hierarchy refers to the physical layout of a computer's motherboard.

• Memory hierarchy is a method of organizing software applications in a system.

What are the different levels of memory hierarchy?

• Virtual Memory

• Flash Memory

• Registers, Cache, Main Memory, Secondary Storage, Tertiary Storage

• Network Storage

What is the primary function of secondary storage devices?

• To store data persistently.

• To increase processing speed.

• To provide temporary data storage.

• To enhance system performance.

Name three types of secondary storage devices.

• Network Attached Storage

• USB Flash Drive

• Hard Disk Drive, Solid State Drive, Optical Disc

• Tape Drive

What is the main difference between HDD and SSD?

• HDDs are faster than SSDs due to their mechanical design.

• SSDs use magnetic disks while HDDs use flash memory.

• The main difference is that HDDs use mechanical parts and spinning disks, whereas SSDs use flash memory with no moving parts.

• HDDs are more expensive than SSDs because they have no moving parts.

How does data retrieval speed compare between HDD and SSD?

• SSDs are much faster than HDDs in data retrieval speed.

• HDDs are more efficient than SSDs for data retrieval.

• HDDs are faster than SSDs in data retrieval speed.

• SSDs and HDDs have the same data retrieval speed.
