Memory Unit: Stores data and
instructions temporarily for quick access during processing.

The speed of a CPU is measured in Megahertz. Higher the value, faster is the information
processed by the CPU.
OUTPUT DEVICES
The output devices are used to display the information and result of computation
to the user. Some of the output devices are:
Monitor
The monitor is one of the most familiar output device. It is
also called Visual Display Unit (VDU). The images that you
see on the monitor are made up of tiny dots called pixels.
The clarity of the images depends on the number of dots/
pixels on the screen per inch. Monitor
Printer
A printer is an output device that allows you to print the work done on the computer
on a sheet of paper. The most commonly used types of printers include:
Dot Matrix Printers: These work similarly to typewriters,
where the printer head strikes an ink ribbon against the
paper to create characters.
Dot matrix printer
Inkjet Printers: These print by spraying tiny droplets of ink
onto the paper, typically doing so line by line.
