INTRODUCTION
Digital technology has become an important part of modern life. Computers, smartphones, tablets, digital cameras, internet services, automated systems and many other technologies are used every day to create, process, store, communicate and access information.
People use digital technologies in schools, homes, businesses, banks, hospitals, farms, government offices, transportation systems and entertainment. Understanding digital technologies therefore helps students understand how modern information systems work and how technology can be used responsibly and effectively.
MEANING OF DIGITAL TECHNOLOGIES
The word digital refers to information represented using discrete values. In modern computers, digital information is commonly represented using binary digits, which are called bits. A bit can have one of two basic values, represented as 0 or 1.
Digital technologies include both the devices used to handle digital information and the systems, software, networks and services that make those devices useful.
CHARACTERISTICS OF DIGITAL TECHNOLOGIES
Digital technologies have several characteristics that distinguish them from many traditional technologies.
| Characteristic | Explanation |
|---|---|
| Digital Data | Information is represented and processed in digital form, commonly using binary values. |
| Speed | Digital systems can process and transmit large amounts of information very quickly. |
| Storage | Large quantities of digital information can be stored in relatively small devices and systems. |
| Connectivity | Digital devices can communicate and exchange information through networks and the internet. |
| Automation | Digital systems can perform many tasks automatically according to programmed instructions. |
| Accuracy | Digital systems can process information consistently when they are correctly designed and operated. |
| Easy Reproduction | Digital information can often be copied and distributed without the same type of physical reproduction required for many traditional media. |
