Unit 1: Technology all around us

  Check which one of these activities you or your friend have done or participated in and format the text as Bold.

   Cooked/ warmed food in a microwave oven.  Drawn cash at an ATM ( Automatic Teller Machine)  Used a telephone.

   Used a dishwasher  Sent/received an SMS  Booked tickets for a movie or show,  Watched a DVD movie.

   Checked the time on a digital watch.  Upload airtime to your cellphone. If you have performed any of the activities in the list, you have used a computer without even realizing that you have. It could be that computer chips have been controlling the equipment or they have helped to create at the program /movie /sound that you have been enjoying. The fact is that computers are here, there and everywhere - and you probably can’t get along without them even if you don’t have PC sitting on your desk at home. Sometimes just taking notice of information we receive in the media, e.g. Reading a newspaper, listening to the radio or watching television can help you to realize and understand how much of an impact computer have on our society.

Task 1:

  1. List three examples where technology is used to :  Present information  Gather information  Control machines/devices

  2. From the picture give three examples of how technology makes our lives easier.

  4. Think about a visit to the Bank or Post Office. Describe all the ways that technology is used there.

  5. Has technology been good for all section of the community? Give an example of someone that may not benefit from ICT and explain why.

  Save your work as: Task 1 and your name and surname.

Unit 2: ICT and personal computer Computers today are all around us

   Laptop The point is that computers come in all shapes and sizes and are often built into other devices. But they share some common features. There are three types of personal computers (pc) in common use.

   Mobile phone

   Calculator

   Watch

   Interactive white board

   Projector

   Printer

   Desktop computer

  Whilst you are reading this page, how many computers are you aware of in the room? Maybe you are in a classroom right now and you are near to a:

  1. Desk-top: designed to be used at home or in the office in one place.

  Desk- tops are often linked together or networked to share software and data. Each PC is then called a workstation.

  2. Notebook or laptop: small, light and

  with built

• –in screen, mouse, speakers, microphone and mode. It has a rechargeable battery.

  extremely small, designed to be carried in a pocket and used anywhere.

  Visit the we How and where are technology being used?

  3. Palmtop :

Task 2:

Hardware

  Hardware is a generic term for any part of the computer that you can physically touch, pick up, hold, move around the room etc. In other words, hardware are the physical parts that Examples of external hardware (not inside the computer):

   Monitor - so you can see what you are working on

   Printer - so you can get a paper copy of your work

   Keyboard - so you can type text, numbers and symbols into your work

   Mouse - so you can point, click and select things on your screen

   Microphone - so you can input voice or sound recordings Examples of internal hardware (inside the computer):

   Hard disk - to store all of your applications and files

   CPU (Central Processing Unit) - the 'brains' of the computer

   Fan - to keep the CPU cool and stop it overheating

   Motherboard - the main printed circuit board in the computer with sockets to connect the other parts

   Sound card - used to generate and capture sounds

Software

  A computer needs to be told what to do, otherwise it will just sit on your desk collecting dust and taking up space.

  Software are the applications and programming instructions that tell your computer what to do and enable you to use it for things such as playing games, writing an essay or listening to music.

  There are two main types of software which you will learn about in detail later on. They are 'systems software' which basically controls the way the computer works and tells it what to do.

  Examples include:  Operating System  Utilities  User Interface The other type of software is called ' application software' and it is this type of software that you use to do your work and have fun. Some examples include:  Word processors such as Word  Spreadsheets such as Excel  Databases such as Access  Games applications such as Half Life, Call of Duty etc

  So software depends on hardware and hardware depends on software. Together they form a computer system.

Task 3A:

  Students work in groups of two or three members and should brainstorm various technology/digital devices they use daily each member should have his own list with daily technology activities.

Student’s next task is to log their daily use and how long they have used of all digital media over 4 days which includes at least

  one weekend day. Saturday Sunday Monday Tuesday Television 30 min Microwave 20 min Computer 60 min Dishwasher 120 min PlayStation 60 min IPad 30min Cellphone 25 min Some examples include: phone usage, gaming (DS, PlayStation, X-Box) playing, surfing the internet, texting and so on.

Save your work as: Task 4 Your name and surname Task 5:

  So you think you know about the web? You think you’re safe? After all it’s all in the computer, so how could it hurt you? Guess again.

  The truth is: it’s a jungle out there! It’s full of traps for the unwary and vicious predators waiting to destroy your life.

  It isn’t safe but you can learn to protect yourself. You can learn to minimize your exposure to dark side of the web. How? By arming yourself with information and shielding yourself with the use of a little commonsense.

  

Research the following question and apply your findings in a Presentation.

Example: PowerPoint.

  1. Identify five types of personal information

  2. Identify types of online “Stranger Danger”

Unit 4: Computer System

  Computer system allows you to enter data, process data, store data and then output the result.

  Input Devices

  Task 4: Design an A4 poster in Microsoft Word that display ONLY input devices .

  The following criteria should be apply.

  1. Heading for your poster.

  2. Format the pictures

  3. Each picture should have a caption Bonus Points: Apply double page border and change the color of the page.

Computer processing

  Processing is the stage where the input data is manipulated in order to produce meaningful information. Processing can include a number of stages such as sorting, searching, calculations, graphing.

  Some examples of processing could include:

  1. Searching sales data to find which products in a supermarket have sold

  the most 2. Sorting a list of customer data into alphabetical order

  3. After a barcode has been scanned (input), retrieving the price of the item

  from the supermarket database and using this data to calculate the customer's bill

  4. Auto tune software: You are at a concert of a world famous singer. The singer knows their voice is a bit wonky this evening with some 'off' notes.

  So they use a computer processing system between the microphone and the main sound system to 'correct' these duff notes in real-time. The audience enjoys a perfect rendition. This is real-time processing in action.

Computer Output: Examples of output could include:

  1. A printout of student examination results displayed in order from highest to lowest.

  

2. A digital display at the petrol pump showing how much fuel has been delivered

and the cost of that fuel.

  3. An alarm from a fire alarm system which has detected smoke in the room.

  Task 6: 1. Insert a table in Microsoft Word.

  2. The table should have 2 columns and 4 rows.
