- 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.
- 9. TYPES OF SECONDARY MEMORY
- 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.
