1. Processing data: The CPU is responsible for executing instructions and performing calculations on data stored in the computer's memory.
2. Controlling input and output devices: The CPU manages the flow of data between the computer's input and output devices, such as the keyboard, mouse, monitor, and printer.
3. Managing memory: The CPU controls the allocation and retrieval of data from the computer's memory, ensuring that programs and data are stored and accessed efficiently.
4. Running applications: The CPU runs software applications, such as word processors, web browsers, and games, by executing the instructions contained in their code.
5. Handling interrupts: The CPU responds to external events, such as user input or hardware errors, by interrupting its current tasks and executing the necessary actions.
6. Performing arithmetic and logical operations: The CPU performs basic arithmetic operations, such as addition, subtraction, multiplication, and division, as well as logical operations, such as comparisons and conditional branching.
7. Managing system resources: The CPU coordinates the use of system resources, such as the computer's memory, storage, and input/output devices, to ensure that multiple programs can run simultaneously without interfering with each other.
