  4. Memory • Memory consists of electronic components that store instructions waiting to be executed by the processor, data needed by those instructions, and the results of processing the data • Stores three basic categories of items: Discovering Computers 2012: Chapter 4 Page 223

  5. Memory • Each location in memory has an address • Memory size is measured in kilobytes (KB or K), megabytes (MB), gigabytes (GB), orterabytes (TB) Discovering Computers 2012: Chapter 4 Page 223 Figure 4-17

  6. Memory • The system unit contains two types of memory: Discovering Computers 2012: Chapter 4 Pages 223 - 224

  8. Memory • Three basic types of RAM chips exist: Discovering Computers 2012: Chapter 4 Page 225 Figure 4-19

  9. Memory • RAM chips usually reside on a memory moduleand are inserted into memory slots Discovering Computers 2012: Chapter 4 Page 225 Figure 4-20

  10. Memory • The amount of RAM necessary in a computer often depends on the types of software you plan to use Discovering Computers 2012: Chapter 4 Page 226 Figure 4-21

  11. Memory • Memory cache speeds the processes of the computer because it stores frequently used instructions and data Discovering Computers 2012: Chapter 4 Page 227 Figure 4-22
