    Historical Context

    The roots of computer science can be traced back to the early 20th century, with significant contributions from mathematicians and engineers. The term "computer science" was popularized by George E. Forsythe in 1961, who defined it as the theory of programming, numerical analysis, data processing, and the design of computer systems. Early computing devices, such as the abacus, laid the groundwork for modern computers, which have evolved significantly over the decades.
