The floppy disks or CD-ROMS with this binary format of the program are sold through computer stores etc. to end users. The computer software maker releases the binary format for sale, but guards the source code and does not release this information to anyone outside the company as this is seen as a strategic asset of the company. This allows the software maker to control the program eg. Hence a user having bought a piece of software is entirely dependent on the company making the software. The advantages of this model are almost entirely biased towards the software maker rather than the end-user.
Program is translated in to binary format.
Download a binary format suitable for their computer and operating system and use this on their computer. Download the source or binary format and put it onto diskette, CD-ROM etc. Such copies of the program on diskette or CD-ROM may then be sold to other individuals or organisations. This model has massive advantages to the end user of the software - there is competition for the supply of any piece of software, as the same software may be obtained in many ways. Also, the fact that the source code is available means that any person in the world including a skilled user can modify the program to fix a problem or to make enhancements.
