digital devices 2

Question 1

multi functional device

Answer 1

A multifunctional device, sometimes known as an MFD, is one that is capable of performing more than one specific function. We also often refer to these as multifunctional peripherals.

e.g printing, scanning and photocopying

Question 2

multi functional uses

Answer 2

Touch screens are used on tablet devices to allow users to input without a separate keyboard or mouse. The screen the user views on is also how they input, by touching objects on the screen or by using an onscreen keyboard.

Force-feedback game controllers are used on games consoles to allow you to control the game and receive vibration output. The vibration output is usually designed to improve the immersive experience of the game, such as rumbling in a car game when you go off track, or a fighting game when you’re hit.

Question 3

Digital Cameras

Answer 3

This is a device that is capable of taking photo and video and recording it as digital data

Question 4

Digital Camera - uses

Answer 4

One of the uses of digital cameras is to allow us to share them using a computer. We often upload pictures and videos to our social networking profiles, like Facebook or Instagram, in order to share them with family and friends. We might also send them to others through the use of email as attachments.

We also use them as we can edit the digital pictures and videos on our computer using photo & video editing software. You’ve often heard of the term ‘Photoshopping’ an image, which refers to the use of a software program called Photoshop that we can use to remove blemishes or perform even heavier changes to a photo.

Question 5

Data Capture & Collection Systems

Answer 5

Data capture & collection systems input and store data through methods other than direct data entry (such as typing on a keyboard). Rather, the data is entered as a result of a related activity

Question 6

Data Capture & Collection System uses

Answer 6

Barcode scanners capture data by reading the widths of dark & light bars. We use these input product items by reading the barcode we find on the back of most products. When the barcode is read it matches it to a database of products on the computer and returns things like the price of the product.

OMR is used in shops for inputting lottery tickets. Pre-printed forms like lottery tickets are designed so that when marks are placed on it, the OMR device can detect what numbers you have selected from the marks’ location on the form.

MICR is used for verifying that cheques are legitimate. A special kind of magnetised ink is used to write a code on the bottom of a cheque. The MICR device reads the magnetic field of the characters to read the code to ensure it is a legitimate cheque.

Obviously, these types of devices are only useful for very specific reasons. They aren’t flexible enough for the general uses we want at home or even in most workplaces.

Question 7

Communication Devices & Systems

Answer 7

A device that is used to move data between two other devices, such as two computers.

Question 8

Communication Devices & Systems uses

Answer 8

Network Interface Cards, for example, allow data to be transferred to and from a networked computer by connecting an ethernet cable. We commonly use these with desktop personal computers.

Wireless dongles allow you to either transfer data to a router wirelessly as part of a local area network or connect to a mobile broadband network. We commonly use these with laptops. WiFi and even mobile broadband connectivity are often integrated directly into mobile devices like smartphones and tablets.

A router directs data to its correct destination over a large network. Wherever two networks meet, a router is required to direct the data in the right direction along the next network in order to reach its destination. You probably use a router at home to allow the multiple different devices in your house to connect to the same internet connection.
