COMPUTER OPERATION AND PROGRAMMING

As has been said, all computers require a program, or list of instructions, to guide their activity. Sometimes the program is designed, or resides, within the hardware of the computer and cannot be changed without redesigning the hardware. More often, the program is entered as software into memory and may be easily removed or altered. In fact, computers that do not have a hardware program usually have several programs available in the memory at the same time. Some of these programs are employed in the general operation of the computer — that is, they control the executive functions. These programs are part of what is referred to as the OPERATING SYSTEM.

Modern computers actually have two sections to the operating system. The first and most primitive section usually is stored in a permanent memory in the hardware. This portion of the system provides setup and connections among basic computer elements, so that more general programs can be entered from a keyboard or loaded from secondary memory. In today’s personal computers this primitive operating system is the BIOS (basic input/output system) that comes with the hardware. The second portion of the system is located in secondary storage for execution when required. These more complex systems, such as DOS and UNIX, perform a wide variety of file-handling tasks using a very structured command set. Yet another layer of operating system uses graphics rather than typed commands. Examples are Windows and Apple products. All these levels have the common goal of making the machine elements interact for the purpose of transferring data.
