A System on Chip (SoC) is an integrated circuit that combines multiple electronic components onto a single chip. These components may include processors, memory units, wireless communication modules, graphics processing units, and input/output interfaces. The goal of SoC technology is to create compact, efficient, and highly integrated computing systems that can perform multiple functions within a small physical space.
In the context of the Internet of Things (IoT), System on Chip (SoC) technology plays a key role in enabling connected devices to function efficiently. IoT refers to a network of physical devices equipped with sensors, connectivity modules, and software that allow them to collect and exchange data over the internet.
Traditional computing systems often require multiple separate chips for processing, connectivity, and memory. SoC architecture simplifies this by integrating all these functions into a single semiconductor chip, improving efficiency and reducing power usage.
