The document discusses the key components of computer architecture: - Input and output devices connect to the computer to enter commands (input) and display processed data (output). Without input there would be no data to process and without output the processed data could not be seen. - Main memory stores programs and data being actively used by the processor or currently being executed. It is sometimes called RAM, for random access memory, since memory cells can be accessed in any order. - The CPU processes instructions and performs calculations and logic operations using the data stored in main memory. It is the brain of the computer that controls all activities within the system.

The Architecture of Computer is
as complex as human being. Their part
have different tasks in order for the
computer to function well. Let’s explore!

Input and Output are devices
connected to the computer that enters
command (Input) then display it
(Output).
Input devices helps computer as
they enter command to it. If there is no
Input device, there’ll be no data to
process. Output device, helps for
displaying the process data. No output
device? We cannot see anything in
computer. Useless.

Main Memory is where programs
and data are kept when the processor
is actively using them or simply where
programs go when they are currently
being executed.
It is sometimes called RAM. RAM
means Random Access Memory.
"Random" means that the memory cells
can be accessed in any order.
