PPT ON INTERNAL STORAGE OF A COMPUTER SYSTEM

2. Temporary memory that stores bytes of data
and program instructions for the processor to
access.
Primary storage area in a computer for
programs and data.

3. Too little or too low quality
RAM can result in poor
computer performance.
RAM is installed in a
computer to match the
computer processor’s
abilities.
Most operating systems
require at least 1 GB to run
smoothly.

4. The CPU, or computer processing unit,
works closely with the RAM to run software
applications.
RAM capacities in new computers range
from 1 GB to 4 GB.

5. Made up of sets of chips
grouped together on a
circuit board.
Single in-line memory
module (SIMM)
Dual in-line memory
module (DIMM)
Located in slots in the
motherboard near the
CPU.

6. Provides permanent storage for data and
instructions that do not change, such as
firmware.
Firmware is programs and data from the
computer manufacturer, including the boot
process used to start the computer.

7. The processor (CPU) and
RAM need electricity to
store data. Both are wiped
clean when a computer
powers down.
The computer needs
somewhere to permanently
store instructions need to
boot up the computer and
load operating systems into
RAM.

8. Stores data using circuits with states that are
fixed, they don’t get erase when computer is
shut down.
The basic function of ROM is to store
necessary software components that open
programs so that you can access the RAM.

9. One program that ROM
stores is the BIOS program.
BIOS stores information
about your hardware
configuration along with the
boot program.
The boot program contains
instructions necessary to
start up your computer.

10. After system diagnostics,
boot program loads parts
of the operating system
from the ROM to the RAM.
Modern computers use
flash BIOS, it has been
recorded on a flash
memory chip.

11. Temporary type of memory.
Made up of tiny electrical charges held in
capacitors, making RAM fast and flexible.
RAM cannot store information without
constant electric flow.

12. If your computer is running programs slowly,
you may need more RAM.
Can always upgrade RAM, specific to your
system.
There is always newer and faster RAM being
developed

13. Permanent type of memory.
Stores instructions necessary for your
computer start up and operate.
BIOS is a large program stored by ROM,
that stores information about hardware
configuration and the boot program.
