Many personal computer users no longer need to write their own programs to make any use of a personal computer, although end-user programming is still feasible. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software (' freeware'), which is most often proprietary, or free and open-source software, which is provided in 'ready-to-run', or binary, form. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers.
Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician.
