History of Computers:
With his conception of the Analytical Engine in the 1830s, Charles Babbage has been associated with beginning the history of computers. Ada Lovelace created the first computer program because she saw its promise. However, electronic computers did not become widely available until the middle of the 20th century. Built in 1946, the first electronic computer with a general purpose was called ENIAC. Mainframes and minicomputers were developed in the 1950s and 1960s, while microprocessors were introduced in the 1970s. In the 1980s, Apple and IBM helped usher in the era of personal computers. Next came quick developments, such as the emergence of the internet and the revolution in mobile computing. Steve Jobs and Bill Gates were two innovators who significantly influenced the development of the computer.
Computers are made up of two basic components: Hardware and Software
What is Computer Software?
A computer may perform operations according to a package of data and instructions called computer software. It includes operating systems, apps, and programs that enable hardware interaction from the user. The computer’s actions are guided by software, which enables it to analyze data, run programs, and carry out particular tasks for a variety of uses.
Examples:
Examples of computer software include operating systems like Microsoft Windows or macOS, which manage hardware resources and provide user interfaces. Productivity software, such as Microsoft Office or Google Workspace, assists in document creation and collaboration. Web browsers like Google Chrome or Mozilla Firefox enable internet access and interaction with online content.
What is Computer Hardware?
Computer hardware comprises the physical components of a computing system. This includes the central processing unit (CPU), memory (RAM), storage devices (hard drives, SSDs), and peripherals like keyboards and printers. Hardware enables the execution of software, facilitating the processing and storage of data in various computing devices.

Fundamentals of computer:
The fundamental functions of a computer include a variety of operations that when taken as a whole enables the device to operate and being beneficial Among these tasks are:
- Data Processing: Computers manipulate information in accordance with preprogrammed instructions by processing data using arithmetic and logic operations.
- Storage: Computers use storage devices like hard drives or SSDs to store data permanently, enabling it to be kept on hand even when the power is out.
- Input: Keyboards, mouse, and touchscreens are examples of input devices that computers use to accept data and commands.
- Result: They use output devices like speakers, printers, and displays to present data or deliver outcomes.
- Memory: Computers store temporary data and programs in RAM (Random Access Memory), which makes it easier to retrieve commonly used files and applications quickly.
- Execution of Programs: In order to carry out particular tasks, computers run programs, which are collections of instructions.
- Communication: Computers are capable of exchanging data and enabling networked operations through communication with other systems and devices.
- User Interface: Operating systems offer a user interface that lets users communicate with computers via command lines or graphical user interfaces.
Together, these fundamental operations enable computers to carry out a vast range of activities, from straightforward math operations to intricate simulations and data processing.
