What are the basic functions of a computer?

The basic functions of a computer are fundamentally centered around the handling of data. This includes taking data from users, which refers to the input process where data is entered into the system. Once the data is received, the computer processes it, which can involve calculations, data manipulation, or running applications to produce meaningful information. Finally, the processed data is either displayed to the user or stored for future access. This cycle of input, processing, and output/storage encapsulates the core functions that define a computer's utility, emphasizing its role in transforming raw data into useful information.

The other options, while they mention aspects of what computers can do, do not summarize the basic functions as clearly and comprehensively as this one. For instance, while establishing connections is important, it doesn’t encompass the fundamental data handling aspects. Additionally, managing networks and enhancing graphics, as mentioned in other choices, are more specialized functions that rely on the fundamental abilities of input, processing, and output/storage rather than constituting the basic functions themselves.
