Supercomputers are the giants of computing, first appearing in the 1960s with machines like the Cray-1 in 1976. They were built for tasks such as weather prediction, nuclear research, and space exploration. Today, they power artificial intelligence, drug discovery, and complex simulations. They are the fastest computers in the world but also the most expensive, requiring special buildings and cooling systems. Examples include Fugaku in Japan and Frontier in the USA.

Mainframes have been around since the 1950s and are still essential for banks, airlines, and governments. They can process millions of transactions at once and run non-stop 24/7. Famous systems like the IBM Z Series highlight their reliability and stability. However, they are costly, difficult to maintain, and less flexible than modern computing solutions.

Minicomputers rose to popularity between the 1960s and 1980s, providing a smaller and cheaper alternative to mainframes. They were useful for universities, labs, and medium-sized businesses, serving multiple users efficiently. Yet they were less powerful than mainframes and eventually became obsolete with the rise of personal computers. A well-known example is the PDP-11.

Personal computers, or PCs, revolutionized technology in the late 1970s with the Apple II and IBM PC. They quickly became part of daily life, used for writing, gaming, studying, and working. Available as desktops or laptops, PCs are versatile, affordable, and often upgradeable. Their downsides are lower power compared to large systems, vulnerability to viruses, and the need for constant updates.

Mobile computers expanded on this by adding portability. Starting with laptops in the 1980s and later evolving into tablets and smartphones, they allow people to work and play anywhere. Examples include the iPhone, iPad, and Samsung Galaxy. They are convenient, battery-powered, and portable, though usually less powerful than desktops, harder to upgrade, and limited by short battery life.

Embedded computers, on the other hand, are hidden inside everyday devices. Since the 1970s, they have powered cars, appliances, and industrial machines. They are small, cheap, and energy-efficient, designed for specific tasks only. While they cannot be used as general-purpose devices, they are highly reliable within their roles, such as in car control systems or factory equipment.

Wearable computers are the newest trend, becoming popular in the 2010s with devices like smartwatches and smart glasses. They integrate technology into daily life by tracking fitness, monitoring health, delivering notifications, and even enabling augmented reality. Examples include the Apple Watch, Google Glass, and Fitbit. Their advantages are lightness and convenience, but they face limitations like small screens, short battery life, and dependence on smartphones.
