Question: A device, which is not connected to CPU, is called as …….

Answer:

A device that is not connected to the CPU is commonly referred to as a "peripheral device" or simply a "peripheral." A peripheral device is an external device that connects to a computer system but is not an integral part of the central processing unit (CPU).

Peripheral devices serve various purposes and provide additional functionality to the computer system. They can be classified into several categories, including:

1. Input devices: These devices allow users to input data into the computer system. Examples include keyboards, mice, scanners, and cameras.

2. Output devices: These devices present data or information generated by the computer system to the user. Examples include monitors, printers, speakers, and projectors.

3. Storage devices: These devices are used for data storage and retrieval. Examples include hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and optical discs (such as CDs or DVDs).

4. Communication devices: These devices enable communication between the computer system and other devices or networks. Examples include network interface cards (NICs), modems, routers, and wireless adapters.

5. Peripherals for specialized purposes: These are devices designed for specific tasks or industries. Examples include barcode scanners, MIDI controllers, graphics tablets, and medical imaging devices.

Peripheral devices typically connect to the computer system via various interfaces, such as USB (Universal Serial Bus), HDMI (High-Definition Multimedia Interface), Ethernet, Bluetooth, or Wi-Fi. They expand the capabilities of the computer and allow users to interact with the system, store data, communicate with other devices, and accomplish specific tasks beyond the processing capabilities of the CPU alone.
