when Robert L. Patrick implemented a very primitive operating system for General Motors Research in 1956. His operating system design, labeled GM-NAA I/O (General Motors – North American Aviation Input/Output), consisted of three parts. It received an input, made a computation, and submitted an output. This early operating system allowed each of the (approximately) 40 IBM 704 mainframes to process jobs simultaneously one after another. This was the start of a beautiful component that would give

effectiveness possible only with the help of computers. These systems operate using the Von Neumann Architecture. The Von Neumann Architecture and Importance The von Neumann architecture is a design model for a stored-program digital computer that uses a processing unit and a single separate storage structure to hold both instructions and data. The instructions are executed sequentially which is a slow process. One shared memory for instructions and data with one data bus and one address bus between processor

Assignment 3: Input Controls and Restricting User Interface INPUT CONTROLS No matter how data enters an information system, the quality of the output is only as good as the quality of the input. When developing or purchasing a new system or application, it is important that the system or application has adequate input controls. “Input controls ensure the complete and accurate recording of authorized transactions by only authorized users; identify rejected, suspended, and duplicate items;

CHAPTER 1 INTRODUCTION Overview of the current system Computer world is now at our hands, this give improvement and development of all programs in the different agencies, in offices and in schools. Paper work become easy, computation is faster, record keeping and bringing out is fast. In schools, all works became easily fast to look at record, easily to reproduce student record. Since, computation of grades is one burden of the teachers, computerization made the answer in solving, in recording

International Group(AIG) uses to quote their commercial auto(CA) business lines, how it effects the deliverance of quotes to their clients and approaches to a solution. AIG uses a standardized commercial auto rating system(CARS) that electronically outputs a rating. The input procedure isn't electronic by any means and can be very timely and costly due to the number of people involved, the excessive amount of paper being used and the turn around time for their clients to receive a quote. If AIG adopted a more

for storage and use. Both UNIX and Windows file systems are ordered and both support lengthy names as much as 255 characters. File Processing Evaluation UNIX programs that are based upon simple text files for setup use a lot of powerful devices that are utilized to process text files. Piping is widely utilized to reroute the result of one command to the input of the subsequent command. UNIX deals with most command in a consecutive order (first in first out) but the procedure may be overridden
