The first attempt at improving the efficency of was to take away the slowest part of the process (the human being) and to use some other method to first collect all the input data. Once the data has been collected it could be input to the processor using the fastest input devices available. In this way one processor can be used to satisfy the demands of a number of users, although it may be some time before a response is produced as all the input data has to be collected before the processing is done. A good example is when workers input the times at which they start work and finish work each day during the week. This data is collected in some way and then input into the computer and only when all the data is collected it is used to calculate the pay for each worker for the week, The OS which insists on being collected together first and then input all together is called a Batch OS. Batch OSs where developed in the 1950s because there were very few computers but lots of people wanting to use them. The only way to satisfy demand was to stop people slowing the computer down.
