Memory refers to
Types of Memory :-
There are basically two types of memory which are categorised in a computer system ,they are:
1) Primary memory
2) Secondary memory
1. Primary memory
It is a type of volatile memory in which the data is stored temporarily until the software’s is accessed or processed, it is the memory which
Example : SRAM( Static Random Access Memory ), DRAM( Dynamic Random Access Memory ), etc.
2. Secondary memory
It is a type of non – volatile memory in which data is stored for a long period of time and can be executed at any time later, it is the memory which can exist even after power supply is off. Secondary memory can also be a external storage device.
Storage is said to be a physical space ( Rather is in GB or MB ) which can be externally connected to a device for storing media, software, games, etc of different volume. It can also
Example :- Floppy Disk , Hard disk , Magnetic tape, etc.
Memory measurement table of the storage (unit of computer memory measurement) :-
computer storage units smaller to larger
|Unit||Short Name||Full Name|
|1 Bit||Bit||Binary Digit|
|8 Bits||1 Byte||Byte|
|210 i.e., 1024 Bytes||1 KB||Kilo Byte|
|210 i.e., 1024 KB||1 MB||Mega Byte|
|210 i.e., 1024 MB||1 GB||Giga Byte|
|210 i.e., 1024 GB||1 TB||Terra Byte|
|210 i.e., 1024 TB||1 PB||Peta Byte|
|210 i.e., 1024 PB||1 EB||Exa Byte|
|210 i.e., 1024 EB||1 ZB||Zetta Byte|
|210 i.e., 1024 ZB||1 YB||Yotta Byte|
|210 i.e., 1024 YB||1 Bronto Byte||Bronto Byte|
|210 i.e., 1024 Bronto bytes||1 Geop Byte||Geop Byte|
Note that Geop Byte is the highest memory measurement unit till now.
