What is it and why do you need it? RAM What is it and why do you need it?

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.

Why would a computer do this?

A computer copies the application and data currently in use to the RAM because it is much faster to access than accessing the hard drive over and over again.

What part of the computer does the reading/writing to/from the ram???

THE CPU

The CPU uses Dynamic Random Access Memory (DRAM) DRAM Functions like a spreadsheet which holds 1’s and 0’s

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

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.

ALL computers use dram both PC and Mac
