Elements of information systems The process of data input into Nazi and apply processing output is information technology it is a process of information system. A computer is a device that allows data processing information needs. That is one element of the information system. The information system contains five elements, namely hardware (Hardware), software (Software), data (Stored Data), personnel (Personal) and operational procedures (Procedures) (somjit may Indra and Indra. 2540: these beauty, may 4-7), which are as follows: 1. hardware (Hardware) as the first element of the information system on which hardware this will mean using computer equipment, data collection and data processing for. Creating information technology include the computer, which is available from micro computer. Mini machine mainframe computers, computer or even a machine super computer which is the largest machine in addition to this, information technology is also stored in the network (the Network), which is the link. Micro-computers and with such large mainframe computer machine as well and now computers have more equity or communications channel connection (Connectivity) to increase the capabilities of your computer to be able to share information with other computers, such as networking, Internet allows users to expand the capabilities and benefits of the data so that the data is published to multiple sources quickly. 2. software (Software) is a component of information technology, which refers to generates a system command or a set of programs that are written to use the computer to working order can be divided into 2 major categories include: software, system software (System Software), a program that controls the computer, able to work smoothly, including control of devices connected to the computer system and software application (Application Software) is a program developed to work in a particular. 3. ข้อมูล (Stored Data) คือข้อมูล หรือข้อเท็จจริงที่ยังไม่ได้ประมวลผล รวมทั้งข้อความ ตัวเลข รูปภาพ และเสียง ข้อมูลที่เก็บรวบรวมไว้ในระบบคอมพิวเตอร์ และถูกเรียกใช้เพื่อการประมวลผล โดยโปรแกรมประยุกต์ต่างๆ ข้อมูลที่เก็บรวบรวมไว้ในระบบคอมพิวเตอร์นี้อาจอยู่ในรูปของแฟ้มข้อมูลหรือ ไฟล์ (File) ข้อมูลที่จัดเก็บอยู่นี้อาจเป็นแฟ้มข้อมูลเพียงอย่างเดียว หรือหลายแฟ้ม หรืออยู่ในรูปฐานข้อมูล (Database) เป็นการรวบรวมแฟ้มข้อมูลตั้งแต่หนึ่งแฟ้มข้อมูลขึ้นไปที่มีความสัมพันธ์กัน และจัดเก็บไว้ในที่เดียวกันในหน่วยจัดเก็บข้อมูลสารอง เช่น จานแม่เหล็กหรือดิสก์ เพื่อให้บุคลากรจากหลายหน่วยงานสามารถใช้ข้อมูลในฐานข้อมูลร่วมกันได้ 4. personnel (Personnel), the information system will not be able to work if there are no managers. People in this category of personnel at the following: 4.1 users (User) information technology leadership caused the computer system to use, which is not personnel. Need to have much computer knowledge but to know the steps to retrieve the information memorandum from the computer system. 4.2 the worker (Operating Personnel) will be a personnel information, log on to the computer, and NA are the duties runs the task system, applications that are written to order processing, computer and information technology was created and the results from computer system to manage the information it provides to users. 4.3 control and application development user (System and Application Programmer) control who will control the system hardware such as computer controls operate smoothly. There are no problems or waiting fix that may arise from the operation of the computer. For developers, the program will include personnel about the development of various applications to tell your computer to process and create any jobs in the system, etc. 5. operating procedures (Procedures) will be something that tells users how to use the information from the computer system, and how to tell the workers that will be able to order computer system work? Where a worker is required to receive training. Steps to work information system causing skills Chana women it can be used in a computer system efficiently.
