Changes to technology over time has affected many aspects of life. The way we lived in the past is different to the way we live today and this is vastly due to the changes in technology. Technological changes affect the way we work, travel, communicate and play. As students learn about the impact of changing technology they can explore current digital systems and their use. Current digital systems such as computers, smartphones, tablets and laptops have evolved over time. The availability of the Internet provides us with ready access to information anytime, anywhere. Connectivity enables us to conduct our shopping and banking online. We can stay in touch and communicate instantly with friends and family anywhere in the world. Students can consider the impact of these technological changes as they compare a current digital solution with the way this might have been solved in the past.

Current digital systems such as computers, smartphones, tablets and laptops have evolved over time.
The typewriter was replaced by digital systems such as a computer and word processing software.
Telephones have evolved over time into versions that are portable such as mobile phones and, more recently, smartphones. A smartphone is a mini computer and has many more functions than simply making voice calls as was its only function in the past. A smartphone can be used to capture, edit and store photographs and videos. They can be used to play music and video clips. They can connect to the Internet and be used to send and receive emails and SMS’s and they can be used to access and interact with a wide range of mobile apps. They can also be used to operate global positioning systems (GPS) so people can navigate from one location to another.
Technology has changed over time. Many of these changes have improved the way we work, communicate, play and travel.
The Internet provides us with ready access to information. The connectivity provides opportunity to do online shopping and banking and stay in touch with instant communication.
Many homes these days have access to tablet computers. These ‘mobile computers’ include a camera for stills and video, and a microphone. The touchscreen has eliminated the need for a mouse or keyboard.
This section integrates ICT capabilities with their exploration of digital systems.
Software consists of the applications that make the computer work and tell it what to do.
A computer is a common digital system. A tablet device, laptop and smartphone are also digital systems.
The digital system uses hardware and software component to enable a user to complete specific tasks.
Hardware refers to the physical parts of the computer that you can touch. In a desktop computer it includes the case (or tower), the monitor, keyboard and mouse.
The software are the applications that make the computer work and tell it what to do. These might include word processing and presentation software, a drawing program, photo editing, video playing and other applications.
Peripheral devices can be connected to the computer.
