Processor Modes - Real Mode 

Because it is based on the 8086 and 8088 CPUs, the real mode is sometimes called the 8086 modes. The original IBM PC had an 8088 CPU that could only access 1MB of memory using 20 address lines and could only execute 16-bit instructions using 16-bit internal registers. This chip was developed with a 16-bit instruction set and a 1MB memory model in the schematic diagram, and all original PC software was written to run with it. For example, 16-bit instructions are used in DOS and all DOS software, Windows 1.x through 3.x, and all Windows 1.x through 3.x programs. These 16-bit operating systems and programs are optimized for the original 8088 CPU.

Later processors, such as the 286, could execute the same 16-bit instructions as the 8088, but at a considerably quicker rate. In other words, the 286 was backward compatible with the original 8088 and could execute all 16-bit software the same way an 8088 could, but at a quicker speed. Real mode refers to the 16-bit instruction mode used by the 8088 and 286 CPUs. All real-mode applications must use only 16-bit instructions and stay under the memory architecture's 20-bit (1MB) limit. This sort of software is generally single-tasking, meaning it can only run one program at a time. There is no built-in protection to prevent one application from overwriting another or even the operating system in memory. As a result, if many programs are executing at the same time, one of them might put the entire system to a standstill.
