Like the later ENIAC of 1946, Colossus did not have a stored program, and was programmed through plugboards and jumper cables.

Stored program control exchanges in the 1970s had teleprinter channels for entering and verifying translation information, which allowed centralizing these functions.
43.
The theory of DDAs was not developed until 1949, one year after ENIAC had been reconfigured as a stored program computer.
44.
This service became commonplace in the 1970s with the spread of Stored Program Control exchanges capable of implementing the required databases.
45.
Strowger exchanges are usually direct control systems, whereas crossbar, electronic exchanges including all stored program control systems are common control systems.
46.
Teleprocessing users could store programs on disks, tapes, or the RCA RACE mass storage unit interfaced through an RCA 301 computer.
47.
The latter allowed the user to upgrade Palm OS, or, with some external applications, to store programs or data in flash memory.
48.
Coke has already begun to fire back with some in-store programs of its own, said Polly Howes, a spokeswoman for the company.
49.
Practitioners quickly realized that this design was not flexible and came up with the " stored program architecture " or von Neumann architecture.
50.
These included some Crossbar systems, the later version ( 7A2 ) of the Rotary system, and the earlier 1970s stored program control exchanges.
