The same way people need blackboard.
To jot specific thing down so they can be manipulated and retrieved faster with the context intact instead of trying to do everything with your brain.
When the process finish the blackboard is cleared.
If a brain is the CPU and harddisk, the blackboard is the memory.
Because if it didn't it could not store anything
A computer needs memory to store data .
to store the information
The only memory cards you wouldn't need a reader for are ones you would never need to connect to a computer. By definition, memory cards need a reader to be connected to a computer.
Just as you need a computer to put information onto a memory card you will need a computer or something that reads memory cards to print from the memory card
The memory card is already in your computer.
For a basic home computer, you would not need more than 1024MB of memory.
Yes in short it is. A basic explanation of computer memory (or Random Access Memory or RAM) is the place where your computer stores things in the short term that don't need to be remembered (if they did need to be remembered they would be on the hard drive), the more Memory you have the more data can be stored in this space.
you will need a card reader to connect your memory card in a computer, card reader can be plug in a USB port.
It holds programs in its memory so you can multitask. Plus a program needs memory to be run. All computers need memory.
no
You need a Memory Card reader device to connect the Memory card to a computer
You can use it for virtual memory,but you need memory still.
