Data entry method: Questionnaire for printing - Depending on the type of questionnaire, some form of optical data reading diving is the best method. You can easily enter data from questionnaires by combining OMR or optical marker reader with special paper called mark detection form. People simply mark responses from the set of defined answers. Another type of optical data that can be used in the questionnaire is called OCR or optical character reader.

The purpose of this article is to answer questions about various data input / output methods, various storage types and devices, and computer speed. Each of the four questions is divided into corresponding sections below. In the input device section, this article describes user input. It is not an input device used to extract information entered by the user. In all proposed cases electronic scanning methods are the most commonly used method and are commonly used for extracting data and storing it in a repository for editing and analysis It is a method.

Primary memory (in text): "Input data is stored in main memory (memory) after being received from input device and output data is stored in main memory before being sent to output device Execute from secondary memory Saved in main memory Importantly, the computer used in the information system has enough main memory to store the data and program instructions necessary for the current processing. Or, please use the data "When you turn off the computer, this message will not be displayed (unstable).

The four basic functions of the computer are input, processing, output, and storage. Input is information input to the computer. Processing is performing operations on data or manipulating data. The output is the result of data processing. Storage is a device that holds data even when the computer is disabled. - (1) Microcomputer: These computers use a microprocessor chip, and using a chip instead of a CPU means that the microprocessor chip is used as a CPU. These computers are also called personal computers. The two main types of these computers are laptops or desktops. Only one user will use these computers. Therefore, these users are also called personal computers. (2) Minicomputer: These are powerful computers. These computers were founded in the 1960s when the cost of large computers is very high. The minicomputer is cheap, so the user starts to use it
