With the development of microprocessors and related peripherals, the personal computer of today is as powerful as a minicomputer of yesteryears. The processing speed has touched GHz and the hard disk capacity has reached tens of GBs.
Detailed Explanation
Modern personal computers are equipped with advanced microprocessors which significantly enhance their speed and computing power. Today's PCs can process tasks at speeds measured in gigahertz (GHz), making them incredibly efficient compared to older systems. Additionally, storage capacities have vastly increased, often exceeding tens of gigabytes (GB), enabling users to store large amounts of data.
Examples & Analogies
Imagine if your bicycle was suddenly upgraded to a high-speed racing bike β you'd not just be faster, but could also travel longer distances without worrying about the number of rides. Similarly, today's PCs allow individuals to accomplish more complex tasks at quicker speeds than ever before.

Depending upon their size and portability, they can be classified as desktops, laptops, and palmtops. Desktops are personal computers for use on a desk in an office or at home. They are currently the most popular type of computer in use. Laptops, also referred to as notebooks, are mobile personal computers that can be carried in a briefcase. They do not always require an external power source and run on rechargeable batteries for 4β5 hours.
Detailed Explanation
Personal computers come in various forms. Desktop PCs are designed to stay in one place, making them common in offices and homes. Laptops are portable and can easily be moved around β perfect for people who need to work while traveling. Palmtops are even smaller, designed to fit in your hand, but they usually have limited capabilities compared to desktops or laptops.
Examples & Analogies
Consider how different vehicles serve different purposes. Just as a large SUV is great for families but not ideal for solo trips to the grocery store, desktops are suited for stationary use while laptops provide convenience for on-the-go tasks, making it easier to work in coffee shops or during travel.
