Tick () the things used to store objects.
In your previous classes, you have learnt about mathematical tables, addition, subtraction,
etc. It was your memory that saves all the information for you and acts as a storage device.
Similarly, computers also have memory to store all the data and instructions for performing
various tasks and functions. Let us learn what computer memory is and about its function.
MEMORY
The storage space in a computer is called its memory. The data and instructions that are
entered into the computer using input devices are stored inside the memory. There are two
types of memory: primary memory and secondary memory.
Primary Memory
This is the main memory of a computer. CPU can directly access this memory. It is fixed on the
motherboard of a computer. Primary memory is further divided into two types:
1. Random Access Memory (RAM)
2. Read Only Memory (ROM)
Random Access Memory (RAM)
RAM is a temporary memory. The information stored in this
memory is lost when the computer is turned off. That’s why it
is also called volatile memory. It stores data and instructions RAM
given by the user and also the results produced by the computer
temporarily.
