Write short notes on 1). History of computer (emphasizing on computer generation) 2) classification of computers?

1) History of computer (emphasizing on computer generation):
- The history of computers dates back to ancient times when humans used tools like the abacus to perform calculations.
- The first mechanical computer, known as the Analytical Engine, was conceptualized by Charles Babbage in the early 19th century.
- The first generation of computers, developed in the 1940s and 1950s, were large, vacuum tube-based machines that used punched cards for input and output.
- The second generation, in the 1950s and 1960s, saw the introduction of transistors, which made computers smaller, faster, and more reliable.
- The third generation, in the 1960s and 1970s, brought integrated circuits, which further reduced the size and cost of computers.
- The fourth generation, in the 1970s and 1980s, saw the development of microprocessors, which led to the creation of personal computers.
- The fifth generation, starting in the 1980s, focused on artificial intelligence and parallel processing.
- The sixth generation, beginning in the 1990s, witnessed the rise of the internet and the development of more powerful and compact computers.

2) Classification of computers:
- Supercomputers: These are the most powerful and fastest computers available, used for complex scientific calculations and simulations.
- Mainframe computers: These large, high-performance computers are designed to handle extensive data processing and serve multiple users simultaneously.
- Minicomputers: Smaller than mainframes but larger than personal computers, minicomputers were popular in the 1960s and 1970s for scientific and engineering applications.
- Personal computers: Also known as PCs, these are the most common type of computer used by individuals for personal and professional purposes.
- Workstations: These computers are designed for specialized tasks such as graphic design, video editing, and engineering simulations.
- Servers: Servers are computers that provide services to other computers on a network, such as hosting websites or managing data storage.
- Embedded computers: These computers are built into other devices and perform specific functions, such as those found in cars, appliances, or medical equipment.
- Mobile devices: This category includes smartphones, tablets, and wearable devices that have computing capabilities and are portable.
- Gaming consoles: These specialized computers are designed for playing video games and often have high-performance graphics and processing capabilities.
