Do I have to memorise the whole five-stage table?

Yes, all three columns: the period, the technology and the impact on society. The exam questions turn on the third column, so learn each row as a technology and what people could do afterwards.

Is Moore's Law still valid?

The book calls it an empirical observation that held for many years and is now approaching a physical limit. Know the two problems it names (quantum tunnelling and leakage current) and the two new directions (multi-core parallel processing and quantum computers).

Which part of this lesson carries the most marks?

The exam-style question on p. 9 (6 marks) and the scenario tasks on p. 10. They do not ask you to list the stages; they ask you to use one stage or one definition to explain a change for real people.

Lesson 1-1

Development of Information Technology and Social Transformation

Unit 1 — Information Technology and Society

Programming & Artificial Intelligence — Baccalaureate Year 2

Textbook pages pp. 4–11Published

Five stages of IT from ENIAC to the cloud, Moore's Law, five social changes and four emerging technologies: textbook pp. 4–11, and what the exam asks.

Learning objectives

01Explain the major stages in the development of information technology and the impact of each on society.
02Give examples of the social changes and emerging technologies brought about by information technology, and describe their characteristics.
03Distinguish augmented reality from virtual reality, and explain why autonomous driving relies on edge computing.
04Analyse the impact of one information technology on different groups in society and justify a decision with evidence.

Summary

The lesson opens with an ordinary day in Egypt: a student reads messages on a social networking app, pays for breakfast without cash, joins a class online and orders a book from an online shop. Twenty years ago most of that was impossible. Information technology developed in stages, and each stage changed how people communicate, work, learn and pay, not only how fast machines run.

The first part is history, told as a five-row table of period, technology and impact on society: the birth of the computer with ENIAC and vacuum tubes in the 1940s–60s, personal computers in the 1970s–80s, the commercial Internet and the Web in the 1990s, smartphones and mobile Internet in the 2000s, and cloud computing from the 2010s onward, the stage that made large-scale data analysis and AI practical and turned IT into a service. Beside the table sits Moore's Law, the observation that transistor counts double about every two years, and the physical limits (quantum tunnelling, leakage current) now pushing designers towards multi-core parallel processing and quantum computers.

The second part names five social changes and defines each in one line: social networking services, e-commerce, remote work, online learning and cashless payment. The exam tests these definitions by swapping one part, so exact wording matters more than brand names.

The third part introduces emerging technologies: autonomous driving and why it depends on edge computing rather than the cloud, the contrast between augmented and virtual reality, and quantum computing with its qubits and superposition. The lesson closes with a 6-mark exam-style question on how one stage changed the way IT is used, and a Think-as-an-Engineer task on a cashless society. Both reward one move: take a fact from the book and follow it to its consequence for real people.

Key terms

Moore's Law: The empirical observation that the number of transistors on an integrated circuit doubles about every two years; a historical trend now approaching a physical limit, not a law of physics.
Social networking service (SNS): A service that connects users so they can post and share information; highly effective at spreading information rapidly.
E-commerce (EC): Buying and selling goods and services through the Internet, as online shops do.
Cashless payment: Paying without physical cash, using cards, electronic money, mobile payment apps or QR codes.
Cloud computing: Computing delivered as a service over the Internet from real machines in a data centre; the stage that enabled large-scale data analysis and AI.
Edge computing: Processing data on the device itself, instantly, instead of sending it to the cloud and waiting for a judgement.
Augmented reality (AR) / virtual reality (VR): AR overlays digital information on the real world; VR immerses the user in a space generated entirely by a computer.
Quantum computing: Computing based on the principles of quantum mechanics, expected to speed up certain computations that are hard for classical computers, not all of them.

Sample questions

01A self-driving car must decide whether to brake within a fraction of a second. Explain why the book says this judgement is made on the vehicle itself, using edge computing, rather than by sending the sensor data to the cloud.Understand
02A grocery shop in Mansoura places a QR code on its counter so that customers can pay with a mobile wallet instead of cash. Name the social change from the lesson that this represents, the stage of IT development that made it possible, and the impact on society the book gives for that stage.Apply
03A district council proposes that every shop in its main market accept only cashless payment from next year. Weigh the proposal for three people: a student who already pays by phone, the owner of a small vegetable stall, and a retired man with no bank card and no smartphone. Give one benefit and one drawback for each, then recommend one step and support it with two reasons from the lesson.Evaluate
