source documents, recording the transactions in journals, and posting data from journals to ledgers. 2.

Describe the four major steps in the data processing cycle. 1. Input: The first part of the data processing cycle involves collecting data as well as entering it and then preparing it for the next part of the cycle. 2. Processing : During the second part of the cycle, data is manipulated according to instructions and parameters programmed into the processing application. 3. Output : The form of outputs includes common variations such as results that are printed or displayed on a computer monitor. 4. Interpretation : Assessing and analyzing results: What does the data mean? Discuss the types of information that an AIS can provide. Manual Data Processing : This is the “old-fashioned” way of doing it before the invention of calculators. When data processing is done manually (“by hand”), the process is slow and all mistakes are due to “human error.” Mechanical Data Processing : Data processing results improved dramatically with the addition of typewriters and calculators. However, speed and errors were still very much a function of “human operators.” Electronic Data Processing : Modern data processing uses computers to facilitate processing requirements. Based on data processing instructions provided by human users and programmers, computers now handle an expanding part of the data processing operation. While processing data electronically has become the accepted norm, the underlying technology continues to evolve. For example, replacing “paper forms” is still a work-in-progress for many organizations.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
