In the early days of computers, instructions and data were often divided into two separate storage areas. Modern computers follow what is called a “von Neumann architecture,” a design proposed by the Hungarian-born computer scientist John von Neumann. These machines have one storage area for both data and instructions. Effectively, instructions and data were treated the same, making computer simpler to build and use.
Unix-based operating systems, including Linux, extend this principle to long-term storage. Linux organizes information on a disk as a collection of files.
