Main memory is neither of these.
Random Access Memory (RAM) is the volatile memory that is both an input and an output. You input data into the memory and can output the result on the monitor or print it out on paper, etc.
Normally unless something is broken, it is a storage device (it stores pictures and sometimes videos), an input device (it gets the photos and videos from something within it), and it is an output device (it has a screen)
A CPU is a central processing unit. It is neither an input nor an output device, but it is usually connected to both kinds of devices. An input device would be a keyboard or a mouse. And output device would be a printer, a hard or floppy drive, or a memory chip in a thumb drive.
is an omr and input or output device?
Memory Stick is a flash memory card. It is a data storage. In some situations it can be an input device (when you load pictures from it into an image editor), in some it can be an output device (when you write edited pictures back to your Memory Stick).
Input device.
both input r output
Input device (like a keyboard), output device (like a monitor), memory (like a hard drive), and processor (Intel is a designer of these).
Normally it is an output device. However a touchscreen monitor is both an input and output device.
buffer
It's an input and an output device. Programs and data are input from the hard-drive to the computer's memory for processing. The results are written back onto the drive when you save your work.
The monitor is an output device......
