Is a small unit with a few buttons (keys) on top and which can be rotated on a hard surface. As the mouse moves over the surface, so does the pointer over the screen. There is at least one button on the mouse. Many input devices convert data into mechanical language, i.e. convert the machine into a readable form.

Memory and Control Unit: The information entered by the input units needs to be stored in the computer's memory. The commuter memory stores data, instructions, and the results generated by the process for a short or long period of time. There are different types of commuter memory. Some types of memory are capable of remembering for a very short time, such as as long as the commuter is running or as long as there is uninterrupted power.
This type of memory is called volatile memory. This type of memory is known as primary memory because it is the primary storage memory of the commuter. It is also called temporary memory or main memory. The information inserted through the different units first goes to the main memory (is stored) and stays there electronically (electronically).
This information stays in the main memory until the commuter is switched off. This information is lost when the commuter is switched off or the commuter is reset. We need secondary or secondary memory to store information for a long time. Secondary memory is not temporary and retains information for a long time. Units that use secondary memory are called secondary storage devices. Hard disks and compact disks are common examples of secondary storage devices.
