Here you can find material for Unit 1
Topic 1 - Hardware and software
Digital devices consist of both hardware and software components. From the hardware perspective, it is important to understand the technologies that enable these devices. From the software perspective, it is important to understand licensing and maintenance. Understanding both the hardware and software will enable students to assess and select components to meet the requirements of an individual, organisation or scenario.
Topic 2: Networks
Computer networks are essential to most organisations, enabling them to access their information irrespective of its geographical location, make efficient use of hardware and software resources, and communicate effectively. Network design, based on an understanding of protocols, is fundamental to the way networks work. Such reliance on networks in our society is founded on the assumption that there are mechanisms for securing access to them.
Topic 3: The online environment
The internet and the world wide web are fundamental parts of our digital activity. The rise of cloud storage and cloud computing require more online activity. As more and more people work online and participate in online communities, the issues of potential and risk need to be considered.

Topic 4: IT systems
IT systems are pervasive in organisations. They are used for stock control, booking, asset management, and logistics. These systems operate effectively because they are designed and planned. An understanding of conventional notation will enable students to design systems consisting of both hardware and software components.
Topic 5: Data and databases
Our digital world runs on data. Whether it is personal data or institutional data, it must be organised in such a way that it can be retrieved, manipulated, and understood to have value. Databases are one way in which data is organised, retrieved and manipulated.
Topic 6: Wider issues
The pervasive use of technology has an impact, not just for individuals, but also for the environment and society as a whole. The ability to make judgements about technology is underpinned by an understanding of the moral and ethical issues and the legal frameworks that are part of our lives.
