ICT 1

This printer is used for CAD applications, particularly where large printouts are required such as A0.

Pressure sensors measure the amount of heat in the environment.

This printer is used by applications which require low noise and low chemical emissions, e.g. most networked systems, and applications that require rapid, high quality and high volumes of output, e.g. most offices and schools.

Examples of sensors are (tick all that apply):

A keyboard is used to enter numeric data such as PIN numbers for credit cards and ATM machines.

Most ATM cards and credit cards have magnetic strip at the back which carry the account holder's information

To input text to a computer ready for processing by another
software package such as word processors, spreadsheets,
databases etc. Processing of passports and identity cards.

To input pencil marks on a form such as a school register,
candidate exam answers, any application involving input of a
choice of options

Speakers are needed for any application which requires sound to be output such as multimedia presentations/web sites including encyclopaedias and playing of musical CDs and DVD films.

ATM machines have chip readers to allow account holders to withdraw cash.

Multimedia projectors display data from computers, pictures from televisions and video/DVD recorders.

Washing machines, automatic cookers, and airconditioners have temperature sensors.

To input moving pictures, often pre-recorded, into a computer.

A joystick is a device used by flight simulation software.

What does CAD stand for?

Devices such as iPads and iTouches have touchpads.

Where desktop space is limited, a light pen is used instead of a mouse for drawing applications where a graphics tablet might be
too big. Also used in applications such as operating theatres
where surgeons have little space but require an input device
which can be guaranteed to be clean.

Pointing devices are used in applications that require selection from a graphics interface.

What does TFT mean?

This printer is used for applications where noise is not an issue and copies have to made, e.g. industrial environments (multipart forms,
continuous stationery, labels etc.), car sales and repair companies, manufacturing sites.

What does CRT mean?

To input freehand drawings and retouch photos, you can use a graphics tablet.

This printer is used for applications which require portability and low volume output, where changing cartridges is not an issue, e.g. small offices and stand alone systems, and applications which require very
high quality output and where speed is not an issue, e.g.
digital camera applications.

There are several types of devices that store data. Look at the choices below and tick the data storage devices.

Laptops have touchscreens which allow the user to move the computer's pointer.

In order to enter text into a word processing documents, you use a keyboard.

A trackerball is used by people with limited motors skills to control the computer's pointer.

To input code numbers from products at a POS terminal,
library books and membership numbers.

To input moving pictures from a fixed position into a computer

Scanners are used to enter hard copy images into the computer.

A mouse controls the computer's pointer.
