🏁 Conclusion

• A computer is an electronic device guided by programs to convert input data into useful output information and store it.
• Its units—Input, Output, Memory (RAM/ROM), Storage, CPU (ALU, CU, Cache/Registers)—work together under control.
• Software directs hardware; GPU complements CPU for parallel graphics.
• 64-bit architectures deliver larger address spaces and higher throughput vs 32-bit.
