A keyboard is an input device. A modem is both an input and an output device. A CPU is the central processor and is connected to both input and output devices but is itself neither.
Ram, cpu, storage device, output device, input device, communication device
To type things
Neither. A computer contains both input and output devices. Many modern input and output devices contain embedded computers, that interface between the main computer and the actual input or output hardware of the device.
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.
It is a input device because when you press on a key, you input information. Because, when a key is pressed from the keyboard, it is already information for the computer to process in the CPU and goes to the output devices. Even a single letter typed on a word processing program is still information. -may_pretending
A celeron is a cpu, which makes it a processing device.
Input device (like a keyboard), output device (like a monitor), memory (like a hard drive), and processor (Intel is a designer of these).
CPU is not a peripheral device.
CPU - trust me I already took the test! :)
No. It is a CPU.
