• There are two major categories of memory:
• long-term memory
• short-term memory.

3. L O N G T E R M M E M O R Y
• Long-term memory is our brain’s system for storing, managing,
and retrieving information.

4. S H O R T T E R M M E M O R Y
• Closely related to “working” memory, short-term memory
is the very short time that you keep something in mind
before either dismissing it or transferring it to long-term
memory.

5. R O M ( R E A D O N L Y M E M O R Y )
• ROM stands for Read Only Memory. The memory from which we
can only read but cannot write on it.
• This type of memory is non-volatile. The information is stored
permanently in such memories during manufacture.

6. C O N T …
• A ROM stores such instructions that are required to start a computer.
• This operation is referred to as bootstrap.
• ROM chips are not only used in the computer but also in other electronic
items like washing machine and microwave oven.

8. T Y P E S O F R O M S
• MROM (Masked ROM)
• PROM (Programmable Read Only Memory)
• EPROM (Erasable and Programmable Read Only Memory)
• EEPROM (Electrically Erasable and Programmable Read Only
Memory)

 Non-volatile in nature
 Cannot be accidentally changed
 Cheaper than RAMs
 Easy to test

• RAM (Random Access Memory) primarily serves as the operating
system or CPU for quick access to data that is constantly used to
run a program in a computing device. Simply put, for every
running program on your computer, it requires a certain amount of
data to run them. This data is temporarily stored in the RAM
modules, and processed by the processor of the computer – also
called the CPU (Central Processing Unit)

11. RAM

12. S T O R A G E D E V I C E
• Storage devices are the computer hardware used to remember/store data.
• There are many types of storage devices.
• Hard Disk Drive (HDD)
• Random Access Memory (RAM)
• CD, DVD and Blu-Ray Discs
• DVD-RAM
• ROM
• USB Flash Memory
