The cost of input/output, both inside and outside the computer system, is a topic of increasing concern in the computer industry. The full extent of the problem is often obscured by the fact that much of the expense on input/output, particularly the cost of data collection, is often borne outside the data processing department (DP) and so is not included as part of the DP budget.
Although there have been considerable improvements in the design and performance of electro-mechanical devices, and in the general performance of input/output systems within the computer, these improvements have not been sufficient to keep pace with the ever-increasing amount of data to be processed, expecially in the commercial environment.
This Report examines the factors, both internal and external to the computer, that are currently constraining progress towards more cost-effective computer systems, and discusses several possible avenues of improvement. F.T. Connors of ICL and N. Nisenoff of Forecasting International examine the future of current I/O methods. Specific I/O techniques are described by A.E. Woollaston of the UK Central Electricity Generating Board (key-to-disk); R.M.
