RAM – Random Access memory
When you load a program in Windows, your PC copies the program one line at a time from the mass storage device (usually the hard drive) to RAM. But memory doesn’t just store the programs, but data that is being actively used too.

What part of the computer does the reading/writing to/from the ram???
6
THE CPU
7
The CPU uses Dynamic Random Access Memory (DRAM) DRAM Functions like a spreadsheet which holds 1’s and 0’s
8
ROWS X COLUMNS 1M X 8 Chip = 1M or ROWS X 8 COLUMNS 1M X 16 Chip = 2M ROWS X 16 COLUMNS 1M OR 1 MEG = 1,018,576
10
Why is it called DRAM (Dynamic Random Access Memory
Why is it called DRAM (Dynamic Random Access Memory??? Dynamic = Constantly changing Random = Not planned Access = entry Memory = temporary place for applications and data to be while in use.
11
ALL computers use dram both PC and Mac
