The document discusses computer memory, defining it as various data storage technologies within a computer. It differentiates between primary memory (such as ROM and RAM) and secondary memory (auxiliary storage), highlighting their features and functions. Additionally, it mentions cache memory as a fast storage solution that improves CPU performance.

2. WHAT IS COMPUTER MEMORY ?
Computer memory refers to different types of
data storage technologies used by the
computer. A computer system is made up of a
combination of types of computer memory.

3. FEATURES OF COMPUTER MEMORY
• Location: It represents the internal or external
• Capacity: It is the most important feature of
computer memory. Storage capacity can vary in
external and internal memory.

4. TYPES OF COMPUTER MEMORY

5. PRIMARY MEMORY
Primary memory is also known as the
computer system’s main memory that
communicates directly within the CPU,
Auxiliary memory and the Cache memory.
Main memory is used to kept programs or
data when the processor is active to use
them.

6. TYPES OF PRIMARY MEMORY

7. • Read-Only Memory:Any data which need not be altered are
stored in ROM. ROM includes those programs which run on
booting of the system (known as a bootstrap program that
initializes OS) along with data like algorithm required by OS.
Anything stored in ROM cannot be altered or changed.
• Random Access Memory:Any process in the system which
needs to be executed is loaded in RAM which is processed
by the CPU as per Instructions in the program. Like if we
click on applications like Browser, firstly browser code will
be loaded by the Operating system into the RAM after which
the CPU will execute and open up the Browser.

8. SECONDARY MEMORY
In secondary memory, programs and data
are stored. It is also called auxiliary
memory. It is different from primary
memory as it is not directly accessible
through the CPU and is non-volatile.

10. CACHE MEMORY
It is a small-sized chip-based computer memory
that lies between the CPU and the main memory.
It is a faster, high performance and temporary
memory to enhance the performance of the CPU.
