ICT Prep 1 Term 1, Lessons 1–10: Review
GoalReview green technology, digital change, operating systems, installing and devices with new tasks.
New words

Explanation
This lesson brings together the first weeks of the term. Green technology protects nature. Digital transformation moves services from paper to digital tools. An operating system runs the device. Install means to put a program on a device from a trusted source. A peripheral is a device attached to the computer, and its driver tells the system how to use it. Plug and Play finds the driver almost by itself. We practise with new tasks: match the idea with its example, put steps in order, and hunt for the error. Check each answer by going back to the idea behind it, not by guessing from the length of the words.
Idea
Example
Green technology
a tap that closes by itself
Digital transformation
an online form instead of a paper one
Operating system
runs the device and its programs
Driver
lets the system use a printer
Worked examples
Match: a light that switches on only when someone is in the room matches green technology, because it saves energy. A school that lets pupils hand in homework through a digital form matches digital transformation.
trusted source→run the installer→options and wait→check it works
Order the steps of installing a program: get it from a trusted source, run the installer, choose the options and wait, then check that it works.
connect→system notices→finds the driver→ready
Order Plug and Play for a new printer: connect it, the system notices it, the system finds the driver, the printer is ready to use. Error hunt: “A driver is a cable.” This is wrong; a driver is a small program.
Class activity
Make a set of eight cards: four ideas from this lesson and four examples. Mix them and let a partner match them. Then write three steps of any process on strips of paper, mix them, and let your partner put them in order.
Practice
1
Match the idea: an online form instead of a paper form. Green technology or digital transformation?
Digital transformation.
2
Put in order: check it works, run the installer, get it from a trusted source.
Get it from a trusted source; run the installer; check it works.
3
What does a driver do?
It lets the system work with a device.
4
Error hunt: “An operating system is only a game.” Correct it.
It is the main program that runs the device and lets other programs work.
