What Is Manchester Mark 1?

The Manchester Mark 1 became the world's first commercially to have a general-cause computer. It turned into evolved because of the Manchester Mark 1 at the University of Manchester in 1949. It was constructed and dispensed using Ferranti Inc. because of the Ferranti Mark 1 in 1951. The computer was designed to perform calculations for scientific research. It weighed about a ton and was about the size of a small car, with racks of vacuum tubes and glass valves that filled its cabinets. The machine could perform around 150 calculations per second; this might seem extremely slow by today's standards, but it was pretty fast at the time. The computer used 2,250 vacuum tubes (and only one transistor), which made it very expensive to operate—the cost per hour was £1/hour (around $2 today). It also produced a great deal of heat; it required an air-conditioning system to keep it cool enough for the operation. The computer had no internal storage other than its program memory—which meant that all programs had to be loaded into the machine before running them—but it had an external store that could hold up to 16 words (32 bits) simultaneously. The computing world owes a lot to the IBM 701 and 702 but even more to their oft-forgotten predecessor: the Manchester Mark 1. The Manchester Mark 1 was created by Freddie Williams and Tom Kilburn, who were trying to find a way to make computers more reliable. Their research led them to 34 patents and significantly contributed to subsequent commercial products such as the IBM 701 and 702. Unlike other stored-program computers at the time, which used mercury delay lines for memory storage, the Manchester Mark 1 used Williams cathode ray tubes and magnetic drums instead. This made it faster and more reliable than other machines at the time.
