Input Device
The input device, for example a mouse, tells the processor to pick out applications from the main memory. This is then outputted on a monitor,
all of this happens in nano seconds. The cache in your cpu acts as a buffer so if your computer is working too hard the applications or processes
will stay there until there is more space to get rid of or close the applications or processes. If you want to save your work it will go into the
computers storage until you want to use it again. Processors have certain amount of cores that work at various different speeds. For example
you could have a quad core which has 4 processors or a duel core that only has 2 processors. The speeds is measured in hurtz. A singular hurt is
one tick per second, a mega hurt is 1 million ticks per second and a giga hurt is 1 billion ticks per second. The average computer nowadays has a
processing speed of 3.2GHz which is 3.2 hurtz per second.
2. The Fetch Execute Cycle
Fetches
DecodesExecute
This cycle works as a never ending loop as long the laptop or computer is powered.
Fetches the item from storage or main memory. Decodes the code which is in 0 and 1.
It then executes the actions after decoding it resulting in the application opening.

1) Arithmetic part - which does exactly what you
think it should, it performs the calculations of
the data.
2) Logic part - this deals with logic and
comparisons, for example; it works out the
value, if it greater, less than or equal to.
