Computer Hardware consist of core components such as the processor (CPU), memory and storage and peripherals such as input/output devices Major Hardware Components Categories A computer system has five major hardware components: 1. Input devices: Devices used to get data and instructions (commands) into a computer. 2. Central Processing Unit (CPU)- It processes data and controls the operations of the computer. 3. Primary memory (RAM and ROM): Primary memory stores data and instructions needed by the computer to work. 4. Secondary storage: Secondary storage also called auxiliary storage saves files and programs, so they can be used again later. 5.
