Historical background about Computer

The history of computers dates back to the 19th century when mathematicians began to develop machines that could perform mathematical calculations. However, it wasn't until the mid-20th century that the first electronic computers were developed. Here's a brief overview of the historical background of computers:

1. Mechanical Computers: The earliest devices that could be considered as computers were developed in the 19th century. These were mechanical devices that were used for performing calculations such as the Difference Engine developed by Charles Babbage.
2. Vacuum Tube Computers: In the 1930s and 1940s, vacuum tube computers were developed. These were large and bulky machines that used vacuum tubes for processing data. The first electronic digital computer, the ENIAC (Electronic Numerical Integrator and Computer), was developed during this time.
3. Transistor Computers: In the late 1940s and early 1950s, the first transistor-based computers were developed. These were smaller and more reliable than vacuum tube computers.
4. Integrated Circuit Computers: In the 1960s, integrated circuits were developed, which allowed for the creation of smaller and more powerful computers. This led to the development of mini computers and mainframe computers.
5. Personal Computers: In the 1970s, personal computers started to become available. The first personal computer, the Altair 8800, was developed in 1975. This led to the widespread use of computers in homes and businesses.
6. Internet and Mobile Computing: In the 1990s, the internet became widely available, which revolutionized how people use computers. In the 2000s, mobile computing became popular, which led to the development of smartphones and tablets.

Today, computers are an essential part of our daily lives, and their development continues to shape the world we live in.
