Data processing involves the conversion of raw data and the flow of data through the Central Processing Unit and Memory to output devices. Each CPU in a computer contains two primary elements: the Arithmetic Logic Unit (ALU) and the control unit. The Arithmetic Logic Unit performs complex mathematical calculations and logical comparisons. On the other hand, the control unit accesses computer instructions, decodes them, and controls the flow of data in and out of the Memory, ALU, primary and secondary storage, and various other output devices.
The internet is a vast network that connects computers, cellular devices, and cable together from all over the world. There is wireless internet (Wi-Fi) which doesn’t use lines/cables to connect to devices. Cellular technology provides wireless internet access through cellphones. Finally there is satellite which travels an enormous distance from Earth to a satellite.
