Colossus worked by holes punched in a paper tape. It was programmed by switches and plugs. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations.
Colossus was programmed by instructions punched on a roll of paper tape.
The holes in the Colossus computer were designed to hold punched tape, which stored messages and data for processing. This method allowed the Colossus to read and interpret encrypted messages during World War II, particularly those generated by the German Lorenz cipher machine. The use of punched tape facilitated rapid data input and helped automate the decryption process, significantly aiding Allied intelligence efforts.
The input for Colossus was a paper tape that went through a special optical reader at a speed of 5000 characters per second on a system of pulleys called "the bedstead". There were 8 punch positions per character on this paper tape: 5 holes for the encrypted Baudot character code, 1 character synchronization hole, 1 start hole, 1 stop hole.
Colossus, the world's first programmable digital computer, used punched paper tape to input codes. Operators would create binary sequences on the tape, representing the specific instructions and data needed for the machine to perform cryptographic calculations. The tape was then fed into the Colossus, where its reading mechanism would interpret the patterns of holes as binary values, enabling the machine to execute complex computations to help break German codes during World War II.

cheese.... yes! they used cheese.......
The best tape for drywall repair and installation is typically paper tape or fiberglass mesh tape. Paper tape is more commonly used for seams and joints, while fiberglass mesh tape is better for patching holes and cracks. Both types of tape provide strong reinforcement and help create a smooth finish on the drywall.
Bicycle rim tape is a protective strip that covers the spoke holes on the rim. Its purpose is to prevent the inner tube from getting punctured or damaged by the sharp edges of the spoke holes. The rim tape acts as a barrier between the inner tube and the rim, reducing the risk of punctures and ensuring a smoother ride.
Bike rim tape is a protective strip that covers the spoke holes in a bicycle rim. Its purpose is to prevent the inner tube of the tire from getting punctured by the sharp edges of the spoke holes. By providing a smooth surface, the rim tape helps to maintain the integrity of the inner tube and prevent flats.
Rim tape on a bike serves to protect the inner tube from sharp edges and spoke holes on the rim, preventing punctures and ensuring a secure fit.
