Introduction to Memory S tructure
Overview of Electrical Computers
Electrical computers rely on memory to store and retrieve
data.
Memory structure consists of various components and
systems.
RAM and ROM are common types of memory in electrical
computers.
These memory systems play a crucial role in computer
operations.

Classification of Storage Devices
Understanding Different Memory Types
Storage devices can be classified based on various criteria.
Primary and secondary storage devices serve different
purposes.
Examples of primary storage devices include RAM and cache.
Secondary storage devices include hard drives and solid-state
drives.

Memory Hierarchy
Exploring the Levels of Memory
Memory hierarchy organizes storage at different levels.
Registers offer the fastest access but have limited capacity.
Cache memory bridges the gap between registers and RAM.
Secondary storage provides long-term data retention but
slower access.

Random Access Memory (RAM)
The Heart of Computer Memory
RAM enables direct access to read and write data.
It is a volatile memory type that loses data upon power loss.
DRAM and SRAM are common types of RAM.
RAM capacity and speed greatly impact computer
performance.

R ead-Only Memory (R OM)
Permanent Storage in Computers
ROM stores data that remains even without power.
Firmware and BIOS are examples of ROM.
ROM provides essential instructions during computer bootup.
Data in ROM cannot be altered by normal computer
operations.

Virtual Memory
Expanding Memory Capacity
Virtual memory enables efficient usage of limited RAM.
It uses disk space as an extension of physical memory.
Virtual memory management relies on paging and swapping.
Operating systems dynamically allocate and manage virtual
memory.

Cache Memory
Optimizing Memory Access
Cache memory stores frequently accessed data and
instructions.
It reduces the time taken to retrieve data from main memory.
Cache organization includes different levels and sizes.
Cache hit and miss rates directly impact system performance.

Hard Disk Drives (HDD)
Traditional Storage Technology
HDDs use spinning magnetic disks to store and retrieve data.
They offer relatively large storage capacity at affordable prices.
HDD speed is measured in RPM (Rotations Per Minute).
Access time and data transfer rate affect HDD performance.

S olid-S tate Drives (S S D)
Next-Generation Storage
SSDs use non-volatile memory chips for data storage.
They offer faster data access and transfer rates compared to
HDDs.
SSD technology is more resistant to shock and vibrations.
However, SSDs are generally more expensive per gigabyte.
