Computer Memory
- 1. Computer Memory Presented By Most. Arifa Khatun Bithi 191-35-2656 | 28th Batch Department of Software Engineering Daffodil International University Course Teacher Nusrat Jahan Senior Lecturer Department of Software Engineering Daffodil International University August 5, 2020
- 2. 2 Introduction ď Electronic components that store instructions, data, and results ď Consists of one or more chips on motherboard or other circuit board ď Each byte stored in unique location called an address, similar to seats in a concert hall
- 3. 3 Memory Measure ď§ Bit Smallest Unit of Computer Memory ď§ Byte 8 Bit 1 Byte ď§ Kilo Byte (KB) 1024 Byte 1 KB ď§ Mega Byte (MB) 1024 KB 1 MB ď§ Giga Byte (GB) 1024 MB 1 GB ď§ Tera Byte (TB) 1024 GB 1 TB
- 4. 4 Classification of Computer Memory Memory Internal Main Secondary
- 5. 5 Internal Processor Memory ď A small high speed memory inside the processor ď Temporary storage of instruction and data ď Example: Registers, Built-in cache
- 6. 6 Main Memory ď It is relatively large memory placed outside the processor ď Data and instruction storage for the operation of the processor ď Can be accessed directly and rapidly by the CPU
- 7. 7 Image of Main Memory
- 8. 8 Types of Main Memory Main RAM ROM
- 9. 9 Random Access Memory (RAM) ď It is also called as read write memory or the main memory or the primary memory. ď It is a volatile memory as the data loses when the power is turned off ď Every location can be accessed independently ď Access time for every location is constant and independent of itâs position.
- 10. 10 Types of Random Access Memory RAM Dynamic Static
- 11. 11 Read Only Memory (ROM) ď A class of storage used in computer and other electronic devices ď Data stored in it cannot be modified ď Non-Volatile memory ď Used in calculators and peripheral devices
- 12. 12 Types of Read Only Memory ROM PROM EPROM EEPROM
- 13. 13 Secondary Memory ď Permanent storage of data and instruction ď Much larger in capacity but slower than main memory ď Example: Hard disk, CD, Floppy etc.
