"Ada Lovelace" was known as "mother of computer science" and "Charles Babbage" was known as "father of computer".

Introduction:
The father of the computer is widely recognized as Charles Babbage, an English mathematician, philosopher, and inventor. He is known for his contributions to the development of early mechanical computers. While Babbage is often referred to as the father of the computer, it is important to note that the concept of a computer evolved over time with the contributions of numerous individuals.

Charles Babbage:
- Charles Babbage was born on December 26, 1791, in London, England.
- He is best known for his design of the Analytical Engine, a mechanical general-purpose computer.
- Babbage's work laid the foundation for modern computers and computer programming.
- He envisioned a machine that could perform complex calculations automatically, eliminating human errors.

Contributions:
- Babbage designed and built various machines, including the Difference Engine and the Analytical Engine.
- The Difference Engine was designed to calculate polynomial functions, while the Analytical Engine was a more advanced concept.
- The Analytical Engine featured several key components of modern computers, such as a central processing unit (CPU), memory, and input/output devices.
- Babbage also introduced the concept of loops, which allowed for repetitive computations.

Ada Lovelace:
- Ada Lovelace, an English mathematician, is often considered the mother of computer programming.
- Lovelace worked closely with Babbage and is credited with writing the first algorithm intended to be processed by a machine.
- She recognized the potential of the Analytical Engine beyond mere calculation and envisioned its use for creating music, art, and more.

Legacy:
- Although Babbage's designs were never fully realized during his lifetime, his ideas and concepts laid the groundwork for the development of modern computers.
- His work inspired subsequent generations of inventors and engineers to further explore and refine the concept of mechanical computation.
- Babbage's legacy is evident in the evolution of computers, from early mechanical devices to the sophisticated electronic machines we use today.

Conclusion:
Charles Babbage is widely regarded as the father of the computer due to his groundbreaking designs and concepts. His work on the Analytical Engine and his collaboration with Ada Lovelace paved the way for the development of modern computers and programming. While Babbage's designs were not fully implemented during his lifetime, his contributions laid the foundation for the technological advancements that followed.
