An ICT system diagram

1. An ICT system diagram A system is an assembly of parts that together make a whole. ICT systems are made up of some or all of the parts shown in the diagram. Various devices are used for input, processing, output, and communication. ICT systems can be made of some or all of the parts shown.

2. Input devices, processing and output devices Input devices allow to enter raw data into a computer. The computer processes the data and then produces outputs that we can understand by using an output device. Input devices can be manual or automatic. The processing is mainly handled by the Central Processing Unit (CPU). Manual input devices The most common manual input devices are keyboards and mouses. Let’s discover the other manual input devices ... The teacher divides the students in 7 different teams called: (6 groups with 4 students and one with 5) • yellow team • red team • blue team • green team • purple team • black team • orange team First step ….. Every team has to find and insert 3 images of their device. Every team can get 3 points. The teacher will build the score board step by step.

4. Manual input devices Concept keyboard Each button has a functon. Buttons can have text or picture. Fast food restaurants often use concept keyboards because with a single button you can order an entire meal. 1p solo quella col cibo ...

5. Manual input devices Trackball You can use instead of your mouse. The user rotates the ball which moves the pointer on the screen. Their use is very easy, also for those presenting difficulties in manual movements. 2p media 1,5 molto simili … un po’ inevitabii

6. Manual input devices Joystick If you play a videogame you have a Joystick to control your game. In building construction, joysticks control machinery such as cranes. 3p

7. Manual input devices Digital camera A digital camera takes pictures and can usually record videos, too. The pictures it takes and the videos it records are stored in files. These files can be copied into a computer and then edited. 2p troppo simili … perchè non una web cam?? esterna e in un dispositivo

8. Manual input devices Microphone Microphones are used to input sound. In computing they can be used with voice recognition software and a word processing application to enter text. Webcams usually have built-in microphones, too. 2p media 2 p. troppo simili … perchè non una microfono incorporato di un tablet o smart phone?

9. Manual input devices Touch screen A screenvisual display unit screen that allows the user to give commands to the computer by touching parts of the screen instead of using the keyboard 0 p questi non sono touch screen … al momento sono solo progetti e fantascienza … e comunque non sono toccabili (si tratterebbe di altra tecnologia) c’erano i tablet… che fine hanno fatto?? smart phone?

10. Manual input devices 2p Video digitiser A video digitiser takes an image from a video camera or television and digitises it so that it can be read by, and stored on, a computer. Video sequences captured using a video digitiser are often used in multimediapresentations. le immagini richieste erano 3 ...

11. Manual input devices Scanner A scanner can be used to digitise images. They're similar to a photocopier but they make a digital copy instead of a physical copy. They can also be used with optical character recognition (OCR) software to scan in text that is then editable. 2 p 2 sono uguali (bene la terza). Magari una stampante/scanner/fotocopia?

12. Manual input devices 2p Graphics tablet A graphics tablet consists of a flat pad (the tablet) on which the user draws with a special pen. As the user draws on the pad the image is created on the screen. Using a graphics tablet, a designer can produce very accurate on-screen drawings as if they were drawn on paper. immagini richieste 2… è vero che sono simili ma doveno essere 3

13. Second step ….. let’s play! If you think that new words or verbs need to be explained, please write them in the glossary prepared by the teacher. Remember to write every word in alphabetical order. Make sure you’ve understood! You are going to change group to explain to the other classmates what your device is and how it works. Are you ready? When the teacher asks you to change group, only one student will remain seated waiting for the new classmates. Everybody will go to a different group, so every group will have somebody able to explain each input device you’ve explored. Everybody will talk about each input device at least 25 seconds and no more than 1 minute (you can use a mobile or your ipad to take the time). During the activities, the other members of the group decide how many points to give each student (from 0 to 3 points): - 0 if you don’t say a word - 1 if you can’t explain or the other ones can’t understand what you say - 2 if you can explain and the group understands the general meaning - 3 if you speak plain and the group understands everything very well At the end of these activities, every “colour” tells the teacher the score obtained and you go back to your colour team..

15. Third step ….. once again changing devices: output device Let ‘s start again! Your team is all here and you are going to work on your slide (read the next slide then look for your color). When the teacher asks you to move to another group, rembember you can’t be with the same group you were in the previous activity. At the end of these new activities, every “colour” tells the teacher the new score. Go back to your color team.

16. Input devices, processing and output devices Automatic input devices let the data be entered without any human interventions. Question: what are the differences between automatic and manual input devices? The difference is that a manual input device needs the human source of input ( the data are typedin or some special keys need to be pressed), while automated input devices are used in situations in which the data are already prepared, when the data are collected in a form, the input device can pick them up and transmit them directly into the computer. Automatic input devices Let’s discover the other manual input devices ...

17. Automatic output devices Sensor Sensors are often used as part of a feedback cycle. They collect data continuously and are typically linked to a control program that specifies acceptable levels, eg the minimum and maximum temperature in a green house, the right temperature in your house depending on the time, for your washing machine or your fridge. The control program decides what to do, relying on the data felt by the sensors.

18. Automatic input devices Barcode reader Barcodes are represented by black vertical bars and are read by a barcode reader. Barcodes are printed on many products you buy, each product has a unique code. When read, information stored in the shop database is recalled, such as the product name and price. This information will appear later on your receipt. The scanning process also assists in stock management, reducing the stock every time a product is scanned/sold. Find and insert 3 images, then delete this text. You need different picutres that can help your classmates to understand better and (very important) to remember.

21. Automatic output devices Magnetic Ink Character Reader (MICR) Magnetic ink characters appear at the bottom of cheques. Banks use MICR to read the numbers from the bottom of cheques to obtain data such as account numbers and bank sort codes. A particular font is used, that makes it easy for the machine to discriminate between characters. The ink is magnetised, this makes it immune to creases and dirty marks.
