Broadly, a "biometric device" is any device that measures a biological function or trait. As related to computers, biometric devices are used to control access and/or verify identity. Voice recognition, retinal scanners, palm/fingerprint scanners are all examples of biometric devices. A biometric scanner will take a picture (your fingerprint, your retina) and match it to a previous scan kept on file. Other types of biometric devices, such as voice recognition systems, will record your voice and compare the recording to a sample on file.
The biometric devices are used for security measures.
Biometric security devices can be purchased from several different companies. Some companies that manufacture biometric security devices are Quick Access, Sentry Safe, Viking, Lock Safe, and Gun Vault.
Biometric devices measure (metric) features of living things (bio). To be useful in security (such as authentication and identification), biometric devices measure features of living things that are unique for any individual, such as the Fingerprint Readers now available on most laptops. Other biometric devices include Voice Print Analyzers, Facial Recognition Scanners, and eye (retina or iris) scanners.
It is an input device.

Biometrics is the system of identifying humans through personal characteristics. Examples of biometric systems include the scanning of the iris/retina, fingerprint scanning, and handwriting scanning. Another example of a biometric system is the scanning of the voice in order to recognise the speaker.
Althogh there there are better biometric devices, face recognition is an example of biometric device because it has to recognize your face to authenticate you to a facility.
The most important disadvantage of using biometric devices to authenticate someone is lack of flexibility in conditions. There are many factors which could make identification difficult with biometric devices; such as injury to or loss of a finger, laryngitis, and background noise.
Iris scanners and fingerprint scanners are alternative (biometric) input devices for computers.

Some examples of IP devices are internet modems and routers, EtherNet/IP drive devices, VoIP systems, and numerous electronic devices, such as an iPad.

The influence of biometric devices on either security or privacy will depend upon how they are used. Like any other device, biometric devices can be used appropriately or inappropriately. Does the use of a knife make you bleed to death? But then, maybe you will just chop vegetables.
Most biometric devices would be input devices although they may also utilize storage devices and output devices in their functioning. A biometric device usually takes in biometric information about a person and compares it to information stored in a database - much like username/password methods of authentication compare the username and password to the stored information for a user. Fingerprint scanners, read the fingerprint, convert it to a data stream and then compare it to the stored data previously recorded for the individual, retinal scanners read information about the retinal patterns of a user, convert it to data and compare it to stored data, etc. Note that biometric devices must rely on a storage device, but usually the storage device is not part of the biometric device. Instances of OUTPUT associated with a biometric device might be a signal to open a door or trigger an alarm, but again, the output usually comes from another device that the biometric device is connected to.
There are quite a number of examples of serial devices. Some of them include routers, switches and modems which connect through serial ports.
Yes they are input devices.
output devices are the devices from which the output is obtained. examples: MONITER, PRINTER etc.,
