2. Computer Memory
• A computer Memory is a physical device
capable of storing information permanently or
temporarily.

3. Volatile vs Non Volatile Memory
• Memory can be either volatile or non volatile
• Volatile memory is a memory that loses its
content when the computer or hardware device
loses power. Eg. The random access memory
(ram).
• Non volatile memory is memory that keeps its
data even when the computer loses power. Eg.
the (EEPROM).

4. EEPROM ?
• It stands for Electrically erasable
programmable read only memory.
• It was developed by George Perlegos while at
intel in 1978 and unlike most memory in a
computer, this memory remembers data when
the power is turned off.

5. Two Main Types Of Computer Memory

6. Primary Memory
• This is the memory that the computer
accesses first or directly, it allows the
computer to access running applications that
are temporarily stored in specific memory
location.

7. Secondary Memory
• This is where our program and data are saved
for long term purposes.

8. Difference between the Primary and
Secondary Memory
Primary Memory
• Fast
• Expensive
• Low Capacity
• Works directly with the
processor
Secondary Memory
• Slow
• Cheap
• Large Capacity
• Not connected directly to
the processor

9. Memory Hierachy

10. HDD vs SDD
HDD
• Draws more power (6 – 7
watts)
• It is very affordable
• Typically larger than 500gb
to 2Tb for notebook sized
drives
• Around 30 – 40 seconds
average bootup time
• Slower than the SSD
SSD
• Draws less power (2 – 3
watts)
• It is very expensive
• Typically less than 1Tb for
notebook sized drives
• Around 10 – 13 seconds
bootup time
• 30% faster than the HDD

11. What is this ?

12. Evolution Of External Memory Storage

13. Cloud Storage
• This is a cloud computing model in which data
is stored on remote servers and accessed from
the internet.
• Cloud computing is believed to have been
invented by Joseph Carl Robnett Licklider in
the 1960s.
