Definition of Digital Technology
Technology represents the range of tools and systems that encode information into digital data. This contrasts with analog systems, which represent data with continuous signals. Digital systems rely on discrete values (e.g., bits), enabling speed, accuracy, replication, storage, and programmable computing.
Broadly, digital technology includes:
- Hardware — physical devices like computers, phones, sensors, and servers.
- Software — operating systems, apps, platforms, and algorithms.
- Networks — connections such as the internet, intranets, 5G, and Wi‑Fi.
- Data — structured and unstructured information processed by digital systems.
- Platforms — cloud services, databases, analytics engines.
One of the hallmarks of digital technology is its ability to transform raw data into actionable insights, automate processes, and enable scaling that was unimaginable before the digital revolution.
