describe five most comon types of personal computers

While researching a topic, a student has taken the following notes: The first computer, the ENIAC, was built in the 1940s and filled an entire room. Over time, technological advancements led to smaller and more powerful computers. The invention of the microprocessor in the 1970s was a major breakthrough that enabled the development of personal computers. Today, most people carry a powerful computer in their pocket in the form of a smartphone. Despite their small size, modern smartphones have computing power that vastly exceeds that of early computers.27Mark for ReviewABCThe student wants to highlight the dramatic evolution of computer technology and note the extent of this transformation.
