Which of the following describes a primary function of the ENIAC?

The primary function of the ENIAC (Electronic Numerical Integrator and Computer) was to perform calculations, particularly for complex mathematical problems. Developed in the 1940s, ENIAC was one of the first electronic general-purpose computers and played a crucial role in scientific and military computations, including artillery trajectory calculations during World War II. Its ability to carry out thousands of calculations per second significantly outperformed previous mechanical and electromechanical computing devices.

While ENIAC had limited capabilities for data storage and could perform some logical operations, its strength lay specifically in executing complex arithmetic operations. The design and architecture of the machine were tailored for high-speed numerical calculations, making it ideal for tasks that involved extensive mathematical computations. Additionally, ENIAC did not have any direct means to represent graphical data or store large amounts of information in the way modern computers do, thus emphasizing its focused role in numerical calculations.
