This set of MCQs helps students to learn about basic Peripherals in embedded Systems which are the devices that aid the microprocessor to accomplish a given job. In other words, they serve as accessories to the microprocessor. Depending on their location they can be classified into 2 types, if they are located inside the SoC (expands to System on Chip, in other words, it is just the IC containing the microprocessor ) of a micro-controller they are called on-chip peripherals and if they are located outside the SoC but on the same PCB they are called off-chip peripherals.
