RAM is the computer's temporary storage that allows it to perform tasks by accessing data quickly. It is volatile memory that is erased when the computer is turned off. ROM is permanent storage that contains instructions for starting up the computer and initializing hardware. It is non-volatile memory that retains data even when turned off.
2. Random Access Memory
It is a type of computer memory that allows the
computer to temporarily store and quickly access data
that it needs to perform various tasks.
What is RAM?
3. RAM is like your computer's short-
term memory.
It helps your computer access data
quickly and efficiently, just like your
short-term memory helps you
remember things in the moment.
Random Access
Memory
4. • Run multiple programs at the same time without slowing down
• Can quickly access and manipulate data that it needs to run programs and
applications
• Helps computer run smoothly and quickly overall
Why do we need RAM in our computer?
5. The more RAM you have, the more data your computer
can store and access quickly, which makes your
computer faster and more responsive.
Without enough RAM, can make your computer run
slowly and cause performance issues.
Capacity of RAM
6. RAM is considered "volatile" memory. Any data stored in RAM is lost when the
computer is turned off or restarted.
This is why it's important to save your work before shutting down your
computer.
Remember to save your work!
7. The worst feeling is after writing
pages of work in MS Word your
computer shuts down and you
realize you forgot to Ctrl+S.
When you don’t
save your work..
8. Read-Only Memory
It is a type of computer memory that stores important
data that your device needs to work properly.
It's called "read-only" because you can't change or delete
the data stored in it.
The data stored in ROM is retained even when the device
is turned off.
What is ROM?
9. Think of it like the label on a jar of
peanut butter. Once the label is
printed, you can't change what it
says.
Similarly, the information stored on
a ROM chip is printed during the
manufacturing process, and
cannot be changed by the user.
Read-Only
Memory
10. • Contains a set of instructions that the computer uses to start up and
initialize its hardware components.
• Contains firmware that controls various components in the computer, such
as the hard drive, keyboard, and mouse
