What are the two types of projectors?

digital light projectors (DLP) AND LCD projectors

These are used to project computer output onto larger screens or even onto interactive whiteboards.

Projectors

These printers are primarily used in COMPUTER-AIDED DESIGN (CAD) applications. They can produce solid objects which actually work.

3D PRINTERS

These type of printers are best for one-off photos or where only a few pages of good quality, color printing are needed.

INKJET PRINTERS

A type of printer that uses dry powder ink rather than liquid ink and make use of the properties of static electricity to produce the text and images.

LASER PRINTERS

These are devices that allow computer images to be displayed on a whiteboard using a digital projector.

Interactive whiteboards

This device converts physical values into discrete digital values.

ANALOGUE TO DIGITAL CONVERTER (ADC)

These devices are used to read or measure physical properties.

Sensors

This allows simple touch to launch an application or to carry out many of the functions of pointing devices such as a mouse.

Touch screens

It is used to input sound to a computer which is either built into the computer or are external devices connected through the USB port or using wireless connectivity.

Microphones

This contains a tactile sensor which allows the user to control a cursor by simply moving a finger over the surface of the pad.

Touch pad

This is the most common pointing device with a mechanical ball arrangement; connected to the computer through a USB port

Mouse

It is a kind of injury caused by frequent use of keyboard in hand or wrists..

REPETITIVE STRAIN INJURY

This is the most common device used for data entry. They are used as the input device on computers, tablets, mobile phones and many other electronic items.

Keyboard

This device is used to read matrix of filled-in dark squares on a light background that can hold over 7000 digits.

QUICK RESPONSE (QR) CODE reader

This device is used to read series of dark and light parallel lines of varying thickness that represent information.

Barcode readers/scanners

This device is used in medical fields to create a 3D image of a solid objects for examples in xrays, MRI and more. .

computed tomographic (CT) scanners

Give 5 special face features being scanned using 2D Scanners

• distance between the eyes • width of the nose • shape of the cheek bones • length of the jaw line • shape of the eyebrows

This device is used at airports to to read details of passengers from passports

2D Scanners

This program allows the scanned text from the document to be converted into a TEXT FILE FORMAT.

OPTICAL CHARACTER RECOGNITION (OCR)
