Hardware
The physical elements of computer are known is called
hardware.
1. Input Devices
2. Output Devices

4. Storage devices
Output Devices
An output device is any device used to send data from a computer to
another device. electronic or electromechanical equipment
connected to a computer and used to transfer data out of the
computer in the form of text, images, sounds, or other media.
Monitor/CRT
It is General-purpose color cathode ray tube (CRT)
monitors are used commonly for image display in
personal computer-based picture archiving and
communication system (PACS) and telemedicine systems.
Printer
A hard copy is a printed copy of information from a
computer. You get print out on paper from computer.
There are two types of printer
1) Impact printer
2) Non Impact printer
Impact Printer
a printer that prints by mechanical impacts.
a printing device in which a printing element
directly strikes a surface (as in a
typewriter). It uses a print head that hits the
surface of the ink ribbon.
Non Impact Printer
Non-impact printer is a type of printer that
does not operate by striking a head against a
ribbon. For example, Laser printers and inkjet printers are non-impact printers.
Speaker /Head Phone
Speakers/Head phone are one of the most common output devices used with
computer systems. Speakers/Head Phone are transducers that convert
electromagnetic waves into sound waves. The speakers receive audio input
from a device such as a computer or an audio receiver.,
