3. COMPUTER
• A Computer is an electronic device that accepts data from the user, processes it, produces
results, displays them to the users, and stores the results for future usage.
• To process the data and convert into information, a computer is used.

4. MAIN PARTS OF COMPUTER
• HARDWARE: Computer hardware is what you can physically touch includes the computer
case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case,
such as the hard disk drive, motherboard, video card, and many others.
• SOFTWARE: The computer hardware itself is not capable of doing anything on its own. It
has to be given explicit instruction’s to perform the specific task. Software is a collection of
programs which utilize and enhance the capability of the hardware.

5. GENERATIONS AND COMPUTER
• There are Five Generations of computers:
1. First Generation (1946-1955)
2. Second Generation(1956-1965)
3. Third Generation (1966-1975)
4. Fourth Generation (1976-1985)
5. Fifth Generation (1986-onward)

6. FIRST GENERATION OF COMPUTER
• The first generation of computers refers to the earliest electronic computers,
which were developed in the 1940s and 1950s. These computers used vacuum
tubes for circuitry and magnetic drums for memory. They were large, expensive,
and consumed a lot of electricity. Examples include the ENIAC and UNIVAC I.

7. SECOND AND THIRD GENERATION OF COMPUTER
• The second generation of computers emerged in the late 1950s and lasted
through the 1960s. They were characterized by the use of transistors instead of
vacuum tubes, which made them smaller, faster, cheaper, and more reliable. These
computers also introduced magnetic core memory.
• The third generation of computers appeared in the 1960s and continued into the
1970s. These computers were characterized by the use of integrated circuits (ICs),
which further reduced the size and cost of computers while increasing their
processing power. Third-generation computers also introduced high-level
programming languages and operating systems.

8. FOURTH AND FIFTH GENERATION OF COMPUTER
• The fourth generation of computers began in the late 1970s and continued into the
present day. These computers are characterized by the use of microprocessors, which
allowed for even greater miniaturization, increased processing power, and lower cost.
Fourth-generation computers also saw the development of personal computers (PCs),
graphical user interfaces (GUIs), and networking technologies.
• The fifth generation of computers is often associated with advancements in artificial
intelligence (AI) and parallel processing. Although there's no universally agreed-upon
definition, it generally refers to ongoing research and development efforts in areas like
natural language processing, expert systems, neural networks, and parallel computing.
These efforts aim to create machines capable of understanding, learning, and
reasoning in ways that mimic human intelligence
