ICT Quiz - Data Input 02 (Questions)

This KS3 ICT quiz takes a second look at data input. In the world of ICT, inputting data to a computer is a crucial starting point and there are many ways to go about it. If you want to input an image, a digital camera would be regarded as being the input device. This needs connecting to the computer and the image files can then be transferred manually to the computer. Voice recognition has been around for many years and as the the software gets better, it is being used more and more. The input device for voice activated commands or for dictating to word processing software needs to detect sound waves - a microphone!

The above examples are all manual input devices - there are a number of automatic devices too. One way of automating input is to present it in the form of magnetised ink or on a strip of magnetic tape. Some early computers required reels of magnetic tape or small magnetic discs to hold and transfer information. The technology is still used on plastic cards. All that you need to do is to place the magnetised strip (or magnetised ink characters) next to the appropriate reader and it is automatically entered into the computer.

ICT Quiz - Data Input 02 (Answers)

Which device converts documents and images into digital data?

[ ]	Microphone
[ ]	Monitor
[ ]	Pixelator
[x]	Scanner

It uses a moving strip of light to build up the copy of the document or image

Which device converts sound into data?

[ ]	DVD player
[ ]	Loudspeaker
[x]	Microphone
[ ]	MP3 player

Software can then be used to turn it into a digital recording, a voice command or text in a word processor

Credit cards have a magnetic stripe on the back .......

[ ]	to record how much money is left in the account
[ ]	to stop the wrong person using the card
[ ]	to store fingerprint details of the account holder
[x]	to store information to identify the account holder

Swiping the card in a reader transfers the information to the computer system where it can be processed as needed

The magnetic stripe on a credit card is read by a .......

[ ]	magnetic card reader
[ ]	magnetic domain reader
[x]	magnetic stripe reader
[ ]	stripe reader

The stripe stores basic identifying information

Credit cards have a microchip added because .......

[ ]	chips can hold much more data about the customer
[x]	the chips store encrypted data reducing counterfeiting
[ ]	the chips store encrypted data which completely stops fraud
[ ]	the chips hold information about the bank

These cards are more secure but cannot stop fraud totally

Microphones can input sound, however .......

[ ]	the microphones must have a 'Digital' sticker
[ ]	the microphones must have optical inputs
[ ]	the microphones need digital to analogue converters
[x]	the sound needs converting to digital via a soundcard

Microphones produce analogue electrical signals

Banks often use a MICR device. This stands for .......

[x]	Magnetic Ink Character Reader
[ ]	Micro Ink Computer Reader
[ ]	Micro Interface Computer Reader
[ ]	Multi Intelligent Core Responder

One use of magnetic ink is to record data on bank cheques

Sensors are hardware devices which .......

[x]	detect real-world properties and converts them to data
[ ]	detect what is happening in the software
[ ]	flash when there is an error detected
[ ]	make sure that any input data is valid

Examples of sensors are light and temperature sensors as used in science or geography datalogging experiments and investigations

Which of these is not an input sensor?

[x]	Life-form sensor
[ ]	Light sensor
[ ]	Moisture sensor
[ ]	Photo-transistor

A 'life-form' sensor is purely sci-fi - at the moment!
