The components of a computer system involved in program execution include:

1. Central Processing Unit (CPU): This is the brain of the computer where most calculations take place. It interprets and carries out the instructions in the program.

2. Memory: This is where the computer stores data and instructions. The CPU fetches instructions from memory, carries out the operations specified by these instructions, and then stores the results back into memory.

3. Input/Output (I/O) Devices: These are used to interact with the outside world. Input devices (like a keyboard or mouse) allow the user to send information to the computer. Output devices (like a monitor or printer) allow the computer to send information to the user.

4. Storage: This is where the computer keeps data and programs when they are not in use. Unlike memory, storage is non-volatile, meaning it retains its contents even when the computer is turned off.

5. Operating System: This is the software that manages the computer's resources and provides a user interface. It is responsible for loading programs into memory and starting their execution.

6. Bus: This is the system that transfers data between computer components. The CPU uses the bus to fetch instructions from memory and to send and receive data from the I/O devices and storage.

7. Control Unit: This component of the CPU manages the execution of instructions. It controls the operation of the CPU and hence the computer.

8. Arithmetic Logic Unit (ALU): This is another component of the CPU. It performs arithmetic and logical operations.

9. Registers: These are small storage locations in the CPU. They hold data that the CPU is currently processing.

10. Cache: This is a small amount of high-speed memory in the CPU. It is used to hold frequently accessed data and instructions, to speed up program execution.
