Storage

Before compact discs (CDs) or development of the Internet age, software was used on various computer data storage media tools like paper punch cards, magnetic discs or magnetic tapes.

There are four main processing steps in a computer: inputting, storage, outputting and processing.

Computer hardware is the physical parts or components of a computer, such as the monitor, keyboard, computer data storage, graphics card, sound card and motherboard.

They consist of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.

The perishable food storage usually maintains the temperature at 37 to 41 degrees F or 3 to 5 degrees C .
