Data accesses don’t change the DS and ES registers, allowing 64K of data. Medium: Code addresses include the segment address, reloading CS on access and allowing up to 1M of code.Code accesses don’t change the CS register, allowing 64K of code.

Compact: Data addresses include both segment and offset, reloading the DS or ES registers on access and allowing up to 1M of data.

Small: All memory accesses are 16-bit (segment registers unchanged).Tiny: All memory accesses are 16-bit (segment registers unchanged).The general concept is to set different segment registers in the x86 CPU (CS, DS, ES, SS) to point to the different or same segments, therefore allowing various degrees of access to memory. MS-DOS compilers was introduced with the memory models having the 64K memory limitation.

Setup.exe, Install.exe and cmd.exe are some common and well familiar names of EXE files. It is the standard file format to run applications on Windows. Application developers mostly publish their programs for Windows OS in executable format as exe files. exe file is a program that can be executed on Microsoft Windows operating system.
