- lots of resources

Question 5

how is an embedded system different from an electric torch

Answer 5

it can process data

Question 6

pros of embedded systems

Answer 6

Their limited number of functions means they are cheaper to design and build. They can be made smaller too.
They tend to require less power. Some devices run from batteries.
They do not need much processing power. They can be built using cheaper, less powerful processors.

Question 7

cons of embedded systems

Answer 7

They lack the flexibility of non-embedded computer.
It can be difficult to update their software (e.g. the software in a car). However, some embedded devices, e.g. fitness trackers, can often be upgraded by connecting the device to a PC and installing the new software.
