INPUT and OUTPUT Devices

Input and output devices

• Any information or data that is entered or sent to the computer to be processed is considered input.
• Anything that is sent from the computer to an internal or external device is output .

Input devices

• An input device, such as a computer keyboard or mouse , can send information to the computer, but it cannot receive information from the computer.

Output devices

• An output device, such as a computer monitor or printer , can receive information from the computer, but it cannot send information to the computer.
• An input / output device, such as a CD-RW drive or USB flash drive , can send information to a computer and receive information from a computer.

• The Output Devices of computer system
• The Output Devices of computer system are electromagnetic devices or gadgets that accepts or acknowledge data or information's from computer system and translate and converts the data in human readable or intelligent form.
• Generally output can be obtained and acquire mainly in two distinct and different ways Softcopy and Hardcopy . At the point when handled data or information is stored in computer memory is given to an output unit then this processed or prepared data or information is displayed to user in such a way that they can easily read
• The output devices can be classified in the following types and Complete list of output Devices are as follows
• Touch Screens
• LCD Monitors or LED Monitors
• Sound Cards
• Computer monitors are considered to be essential Output devices of PC system .
• They are likewise called as VDU (Visual Display Unit) the screens are massive in size, devour more power, and require part of a room to fit. They seem to be like TV.
• Computer Screens are primarily used to show the handled outcome and result from computer memory to their screen for clients or users. They deliver result in a type of softcopy.
• Touch screens are considered as one of the types of output devices or output gadgets .
• Touch screens can show the data and information to the client or users alongside accepting the information through touch screens it doesn't require input devices of computer system , for example, keyboard or mouse for communication.
• LCD stands for Liquid Crystal Display and LED for Light Emitting Diode . LCD and LED Screens are used as a part of little computers and in addition to laptops.
• This type of innovative technology is used widely in almost all upgraded devices. This screens are more slender and little in weight and does not need huge space for installation, they devour or consume less power and heat when contrasted or compared with CRT Monitors.
• Printers are the prime example of OUTPUT DEVICE of the computer system. They are peripheral devices or electronic gadgets which produces output or outcome on papers. which are called as HARDCOPY.
• Printers are associated with modern day computers or PCs by means of USB or LPT Port with printer cables. Nowadays for quicker preparing and processing USB cables are used .
• Printers come in large variety of sizes and printers with particular task or for special purposes has been created and manufactured for speedier, precise and errand driven printing.
• For instance, printing of pictures or photographs specific printers can be purchased from market.
• Printers can be classified in two types
• Impact Printers.
• Non-Impact Printers.
• Dot matrix and Daisy wheel printers are the prime examples of impact printers. Impact printer utilizes the component of standard typewriters.
• A hammer strikes the paper through the inked strip, the printer has a component which touches the paper with a specific end goal to make content or pictures.
• They deliver low nature and quality of printouts while printing they create noise as the hammer hits the paper through the inked strip.
• This movement makes irritating noise. They are tranquil less expensive and slow as compared with non-impact printers. The Speed of impact printer is measured in CPS Character Per Second and LPM Line Per Minute
• Dot Matrix is an impact printer. This is the least expensive and low-quality printer which produces output in low quality. The dot matrix printer is broadly utilized and used as a part of substantial large associations where mass volumes of printing assignment must be finished.
• Dot matrix printer is generally utilized as a part of printing receipts and bank statements because of its low-quality outputs. Many firms and organizations utilize and use Dot matrix printers for high volume of printout where quality is secondary.
• Laser and inkjet printers are one of the prime examples of non-impact printers. These printers use laser and electrostatic innovation and technology for printing.
• They don't deliver any clamor or noise as they don't touch the paper while creating outputs. They utilize chemicals, warmth and electric signs for making content and pictures.
• They are more costly when compared with impact printers, their quality is better, while printing they don't touch the paper consequently they are quiet and their speed is faster than impact printers.
• The speed of the non-impact printer is measured in PPM Pages Per Minute.
• A Laser printer is a type of non-impact printer. They create great outputs when contrasted or compared with Dot matrix printers, they are costly, faster compared to dot matrix printers.
• Their speed is measured in PPM (Pages Per minute) it can print from 10 pages to 300 pages for every moment. They print page by page.
• Laser printer utilizes ink which is inside the cartridge called as tonner . Static power and warmth is connected to paper for imprinting on the paper . printing are finished by making the picture utilizing laser bar on the photosensitive surface of a drum.
• At the point when the paper moves on the drum, the toner is exchanged to the paper and settled into a perpetual picture.

Presentation Transcript

Input devices are used to enter data from outside world into primary storage & output devices supply the result of processing from primary storage to users. Input device is any peripheral (piece of computer h/w equipment) used to provide data & control signals to an information processing system. Input/output devices make up the h/w interface between a computer . INPUT DEVICE

Keyboard Mouse Scanner Joystick Trackball The most common input devices are following.

The keyboard is the main input device for computers. For instance, boot up a computer without a keyboard and it stops, warning the user that no keyboard is attached. • The keyboard is the only tool available at the command prompt, so it is a necessity for a computer. • It is also used in almost every application like spreadsheets, email, word processing documents and coding. KEYBOARD

. • It is possible to interact with most computers solely through the keyboard, without even a mouse, because they are usually the default input device. Touch screens may eventually overcome the keyboard as well, by providing an onscreen keyboard to save space. • The keyboard is the most common input device. It is almost unheard of for a computer to be without some form of keyboard, be it a full QWERTY keyboard or a smaller number pad, such as those found on a cell phone

Other than the keyboard, mice are the most common type of input device. Nearly every computer has one, and they make navigating the screen much easier than trying to use just a keyboard. Mice usually use a ball, light, or a laser to track movement. Similar peripherals, such as a touch screen or laptop's touchpad, trackballs, graphics tablets, and even joysticks are “pointing” input devices. Touch screens are becoming an increasingly popular pointing device, and someday may replace mice altogether. Mice and other Pointing devices

Scanners allow information such as a photo or text to be input into a computer. Scanners are usually either A4 size (flatbed), as shown below, or hand-held to scan a much smaller area. If text is to be scanned, you would use an Optical Character Recognition (OCR) program to recognize the printed text and then convert it to a digital text file that can be accessed using a computer. scanner

A trackball is a pointing device consisting of a ball housed in a socket containing sensors to detect rotation of the ball about two axes - like a mouse lying on its back. The cursor is moved about the screen by a user rolling the ball with their thumb, fingers, or the palm of their hand. There are usually one to three buttons next to the ball, which are in the same way as mouse buttons. TRACKBALL

The principal advantages of trackballs over mice is that since it is stationary, it requires less space to use, and it can be operated on any type of surface, including the user's lap. These attributes make a trackball particularly suitable for use with portable computers, and they were widely used on laptop PCs before the advent of the touchpad. A further benefit is that because there is no need to physically move the device around’ Like traditional mice, trackballs can be communicate with a PC through serial or USB connections, or in the case of wireless mice, via infrared or radio frequency.

A joystick is a PC peripheral or general control device consisting of a handheld stick that pivots about one end and transmits its angle in two or three dimensions to a computer. Most joysticks are two-dimensional, having two axes of movement (similar to a mouse), but three-dimensional joysticks do exist. A joystick is generally configured so that moving the stick left or right signals movement along the X axis, and moving it forward (up) or back (down) signals movement along the Y axis. In joysticks that are configured for three-dimensional movement, twisting the stick left (counter-clockwise) or right (clockwise) signals movement along the Z axis. joystick

A storage device is a hardware device designed to store information. There are two types of storage devices used in computers; a 'primary storage' device and a 'secondary storage' device. term used to describe any location where information can be held permanently or temporarily for later use. A computer commonly has two types of storage: internal and external. For example, an internal storage is a device such as a hard disk drive and an external / removable storage is a device such as a floppy disk drive. Below are examples of types of storage that can be found on a computer. STORAGE DEVICE

A Floppy Disk Drive, or FDD for short, is a computer disk drive that enables a user to easily save data to removable diskettes. Although 8" disk drives were the first real disk drives, the first widely used an floppy disk drives were the 5 1/4" floppy disk drives, which were later replaced with 3 1/2" floppy disk drives. However, today because of the limited capacity and reliability of floppy diskettes many computers no longer come equipped with floppy disk drives and are being replaced with CD-R and other writable disc drives and flash drives. Floppy disk drive

Short for Compact Disc-Read Only Memory, CD-ROM drives are CD players inside computers that can have speeds in the range from 1x and beyond, and have the capability of playing audio CDs and computer data CDs. CD-ROM

The computer's main storage media device used to permanently store all data on the computer. Also referred to as a hard disk drive or abbreviated as HD or HDD, the hard drive was first introduced on September 13, 1956 and consists of one or more hard disk platters inside of air sealed casing. Most hard drives are permanently stored in an internal drive bay at the front of the computer and are connected with either ATA, SCSI, or a SATA cable and power cable. Below is an illustration of the inside of a hard disk drive. Hard drive

Below is a picture of the front and back of a standard CD-ROM drive.

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) to the outside world. Output device

In computing, input/output, or I/O, refers to the communication between an information processing system (such as a computer), and the outside world. Inputs are the signals or data sent to the system, and outputs are the signals or data sent by the system to the outside.

Speaker Headphones Screen (Monitor) Printer Examples of output devices:

Computer speakers, or multimedia speakers, are speakers external to a computer, that disable the lower fidelity built-in speaker. They often have a low-power internal amplifier. Computer speakers range widely in quality and in price. The computer speakers typically packaged with computer systems are small, plastic, and have mediocre sound quality. Some computer speakers have equalization features such as bass and treble speaker

Headphones are a pair of small loudspeakers, or less commonly a single speaker, with a way of holding them close to a user's ears and a means of connecting them to a signal source such as an audio amplifier, radio or CD player. They are also known as stereo phones, headsets. The in-ear versions are known as earphones or ear buds. In the context of telecommunication, the term headset is used to describe a combination of headphone and microphone used for two-way communication, for example with a telephone. Headphones

A Monitor or Display (sometimes called a visual display unit) is an electronic visual display for computers. The monitor comprises the display device, circuitry, and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube about as deep as the screen size.
