COMPUTER CREATIVE TECHNOLOGY HARDWARE Hardware are the various physical components that comprise a computer system, as opposed to the non-tangible software elements. INPUT DEVICES used to interact with or send data to computer OUTPUT DEVICES provide output to the user from the computer STORAGE DEVICES store data processed by computer COMMUNICATION DEVICES used to send, receive or otherwise transmit information System unit is where all the computer peripherals are attached such as mouse, keyboards, monitors, audio speakers, printers and scanners. The main circuit board of a computer, usually containing the central processing unit and main system memory as well as circuitry that controls the disk drives, keyboard, monitor, and other peripheral devices serves as the brain or engine of the Computer Hardware devices used to store information for immediate use in a computer. Hard disk drive is a non-volatile hardware device and usually the largest data storage in a computer. Source of electrical power of every part in the computer. Video card is a printed circuit board that is used to process images so they can be displayed on a monitor, TV or projector. Sound card is an expansion card that enables a computer to manipulate and produce sounds, and send it to an audio device. Network Interface Card is a circuit board installed in a computer which is used to connect to a network. It also allows a computer to share files from one computer to another. The computer is a system composed of several hardware or devices that have specific functions to make the computer system work successfully. A keyboard allows the user to input letters and other symbols into a computer. It is one of the primary input devices used with computer.  typing keypad navigation keys numeric keypad escape key function keys light indicator A monitor or screen displays information from the computer. A monitor is only used to display (output) information from a computer and provides no source of input.  CRT (cathode ray tube) LCD (liquid crystal display) touchscreen The mouse senses the user’s motions and clicks, then sends them to the computer so it can respond appropriately. A printer is an external device that can be connected to a computer to print text and photos for books, flyers, magazine, newspapers, etc. Speakers are used to produced audio that can be heard by the users. In computer, it is used to generate sound that is created by computer’s sound card. Storage is used to describe the devices capable for storing data. It usually refers to hard disks, tape systems and other forms of storage. Optical storage devices are the storage of data in an optically-readable medium.  CD (Compact Disc) DVD (Digital Versatile/Video Disc) Blu-ray HD-DVD (High Definition DVD) Flash memory is a non-volatile memory chip used to store data. flash drive memory card memory stick A communication device is a hardware device designed to transmit an analog or digital signal from one place to another. A modem is capable of sending and receiving a signal that allows a computer to talk to other computers over the telephone. Commonly Used Communication Devices dial-up modem cable or DSL modem router switch hub
