$149.00$199.00

Students study the main internal components of common digital systems. They consider a range of input/output devices (including augmentative and alternative communication aids) and investigate how the CPU and memory work together to perform calculations and process information. They identify everyday uses of these systems and consider how they are affecting our lives at work and at home. They look at the wide range of computers and consider how hardware specifications affect performance, selecting suitable systems for a range of users.

Students learn about why computers were first connected together and investigate how data is transmitted and secured in wired and wireless networks (including the internet). They learn how to put together the basics of a simple network and get an idea about how larger networks function. They consider the network technology behind phone calls, ATM withdrawals and transport apps and consider the bandwidth and other speed limitations when downloading.

Students learn about protocols and how data is packaged for delivery through the internet. They study how TCP works and what happens when packets are dropped en route. They consider network security and explore simple encryption and decryption algorithms such as ROT13 and XOR.
