2. MEANING OF TECHNOLOGY

Technology is the application of scientific knowledge, tools, machines and skills to solve problems and make work easier.

Technology helps people perform activities faster, more accurately and more conveniently.

Examples of technology include computers, mobile phones, calculators, cars, bicycles and machines used in hospitals and industries.

Explanation:

We use technology in our everyday lives. For example, farmers use machines to cultivate land, teachers use computers to prepare lessons, and doctors use medical equipment to examine patients. These are examples of how technology helps people solve problems and carry out their activities.

3. MEANING OF DIGITAL TECHNOLOGY

Digital technology refers to electronic tools, devices and systems that use digital data to create, process, store and share information.

Digital data is information represented in a form that electronic devices can process, usually using binary digits, 0 and 1.

Digital technology enables people to communicate, learn, work, calculate, store information and solve problems with the help of electronic devices.

Explanation:

For example, when a student uses a computer to type an assignment, the computer processes the work and stores it as digital information.

When someone sends a message through a mobile phone, digital technology helps transmit the message to another person.

Digital technology also allows teachers to use projectors to display lessons and helps students access educational materials through computers and other devices.

4. EXAMPLES OF DIGITAL DEVICES

The following are examples of digital devices:

1. Computer: A computer is an electronic device that accepts data, processes it, produces useful information and stores information. It is used for typing documents, calculations, teaching and learning.

2. Smartphone: A smartphone is a mobile electronic device used for making calls, sending messages, taking pictures, browsing the internet and accessing educational materials.

3. Tablet: A tablet is a portable electronic device with a touchscreen. It is used for reading electronic books, watching educational videos, taking notes and accessing learning applications.

4. Digital Calculator: A digital calculator is an electronic device used to perform mathematical operations such as addition, subtraction, multiplication and division.

5. Digital Television: A digital television is an electronic device that receives and displays television programmes in digital form. It is used for education, news, information and entertainment.

6. Digital Camera: A digital camera is an electronic device used to take photographs and record videos.

Other examples of digital devices include printers, scanners, smartwatches, automated teller machines (ATMs), GPS devices and projectors.

5. AREAS WHERE DIGITAL TECHNOLOGY IS USED

Digital technology is used in many areas of human life.

1. Education: Computers and projectors are used for teaching, learning, preparing lessons and conducting computer-based examinations.

2. Communication: Mobile phones, email and messaging applications help people communicate over long distances.

3. Banking: Computers, ATMs and electronic payment systems are used to manage money and carry out banking transactions.

4. Healthcare: Hospitals use digital equipment to examine patients, store medical records and support treatment.

5. Agriculture: Farmers use digital technology to obtain weather information, access farming advice and monitor agricultural activities.

6. Transportation: Digital technology is used in GPS navigation, traffic control, online ticket booking and vehicle monitoring.

7. Business: Businesses use computers to keep records, manage sales, advertise products and communicate with customers.

8. Entertainment: Digital technology is used to watch films, listen to music, play games and create videos.

6. IMPORTANCE OF DIGITAL TECHNOLOGY

The importance of digital technology includes the following:

1. It makes work easier and faster.
2. It improves communication between people.
3. It supports teaching and learning.
4. It helps people store large amounts of information.
5. It improves accuracy in calculations and data processing.
6. It saves time and reduces some forms of manual work.
7. It helps businesses manage records and communicate with customers.
8. It provides access to educational and other useful information.
9. It supports scientific research and technological development.
10. It creates opportunities for employment and digital skills development.

7. DIFFERENCES BETWEEN DIGITAL AND NON-DIGITAL TECHNOLOGY

Digital technology uses digital data and electronic processing to perform tasks. Examples include computers, smartphones and digital calculators.

Non-digital technology refers to tools and systems that do not rely on digital data processing. Examples include a traditional abacus, a manual typewriter and simple hand tools.

Digital devices can store and process digital information, while non-digital tools may perform tasks mechanically or manually.

Note: Not every electronic device is digital, and not every form of technology is electronic.

8. DIGITAL TECHNOLOGY AND THE INTERNET

The internet is a worldwide network that connects computers and other devices so they can exchange information.

Digital technology can work with or without an internet connection.

For example, a student can use a calculator or type and save a document on a computer without an internet connection. However, activities such as browsing websites and sending email generally require internet access.

9. SAFETY RULES WHEN USING DIGITAL DEVICES

Students should observe the following safety rules:

1. Do not share passwords with other people.
2. Do not share personal information with strangers online.
3. Avoid opening suspicious links or unknown files.
4. Keep liquids away from electronic devices.
5. Do not touch electrical sockets, exposed wires or damaged cables.
6. Use computers and other devices with clean, dry hands.
7. Take regular breaks when using screens for long periods.
8. Ask a teacher, parent or trusted adult for help when something online seems suspicious.
9. Avoid visiting inappropriate websites.
10. Respect other people's privacy and digital property.
