What are 2 components every computer must have -?

Answer 1

Well that depends... the term computer is not limited to the device that I am using to make this post. Here is the Wikipedia definition of computer:

A computer is a machine that manipulates data according to a list of instructions So with this in mind, a human becomes a computer, amongst other things not actively referred to as computers.

Now if you are asking in the context of a Personal Computer, (PC), then things basic requirements are different. For a modern computer to even function properly it requires much more than just two parts. Modern computers are a collaboration of different types of hardware, all working together to achieve a common goal.

Here are the minimalist part requirements for a modern PC that would run an OS like Microsoft Windows:

* Processor - This is the computational unit, the "brain"

* RAM - This is the systems memory, where it stores information temporarily

* Hard Drive - This is where information is stored permanently, beyond the machine losing power

* Motherboard - This is the main board, containing all the different integrated circuits required for the other components to interact with each other.

Answer 2

To pass the POST or power on self test, a computer must have a working keyboard and monitor at a minimum. In order to function properly, it must have a motherboard, processor, at least one stick of RAM, hard drive, power supply, keyboard, monitor, and BIOS. If any of those are missing, incompatible, inadequate or damaged, you'll get little more than error messages from the computer.
