Instruction Set is NOT the same with program codes (programming).

Instruction Set is NOT a machine language.

x86 Architecture is the standard of CPUs.

Set of operations which are decoded in sequence (these operations instruct ALU and CU.)

Informs the CPU what operation needs to be done.

Data which needs to be acted on or it can refer  to a register in the memory.

Has a compact operating system (OS)

Has ​an integrated circuit which only has a CPU on the chip.

Has ​a single chip where RAM and ROM and other peripherals are embedded which carry out a specific task. integrated circuit which only has a CPU on the chip.

Its example is Arduino.

One of its examples is the Qualcomm Snapdragon that can be found in smartphones.

They are small in size and therefore easy to fit into devices.

Compared to other systems, they are relatively low cost to make.

It can be difficult to upgrade some devices to take advantage of new technology.

Troubleshooting faults in the device becomes a specialist task.

They are usually dedicated to one task allowing simple interfaces and often no requirement for an operating system.

Although the interface can appear to be more simple in reality it can be more confusing to change some settings.

They consume very little power.

Any device that can be accessed over the internet is also open to hackers, viruses,etc.

They can be controlled remotely using a device(for example mobile phone).

Very fast reaction to changing input.

With mass production comes reliability.

Due to the difficulty of upgrading and fault finding, devices are often just thrown away rather than being repaired.

Can lead to increase in the 'throw away' society if devices are discarded just because they have become out-of-date.
