Chapter 3Tracing information Regular units of the essence. Nowadays, there are a lot of data published on the Internet is constantly increasing amount of information is khaosanklai everyday life. Health science professions, it is necessary to rely on the State-of-the-art knowledge to work, so users of the Internet to learn about techniques to search for information on the Internet. By using the service from a Web site that offers tools to find information on the Internet source of information on the Internet is rapidly expanding continuously. There are a lot of mayomhasan information, make. Is the current era of Internet users (con user-generated) The user group community with social networking (social network) is a lot like HI5, MySpace, Wikipedia, Faceebook web blog.

Annual unit performance Show knowledge about the search information. Tracing information Tracing information from electronic systems in all current systems. Should have basic knowledge about information and search the database first. Include the trace data from a duplicate than other computer efficiently. Tracing information refers to the process of searching for information technology by using various formats, search tools to search for information technology is divided into two ways.1. information technology system tracing tools (Manual System), such as the card card tancha Ney magazine.2. trace a computer system with information technology (Computer System), which can be searched through the database include computer hardware, electronic books, periodicals, electronic and information technology, on the Internet etc.Information search tool The tool is a device used to find books that are available in the library to use the computer to learn include: The search is to find information about the book in the journal study project that there Gallop books that students want to or not. If there appears to be in a category. The data contract is the human perception and the Plains brought record contracts look. When the data is managed, so changing the content or meaning of the information technology level. Information technology is a fact. An event that is televised and recorded in various formats such as audio and visual material, newspapers, periodicals, books, computers and the spoken word is beginning to be used in making a decision or respond to various issues (reproductive-2543 (2000) phornprapha, son). The components of the tracing tool contains information 1. the screen is a device that sends out (Output devices) or one type of computer display unit using the information display monitors usually contain information both as letters and graphics. 2. the keyboard is a device (Input devices), the import data as a primary device that is used to import data into the computer. It is a typically rectangular or nearby, there are approximately a hundred keys on the keyboard do not key (depending on your keyboard map) of a typewriter to make data entry as simple characters and numbers and more comfortable keyboard, so that the Panel is a key character with separate numeric keypad and separate vacation if. 3. a mouse is a device data import (Input devices) that are used in standard usage in the computer that controls designed to fit by a concave curve to curve, and part into the user's hands and noticed by the South by the mouse will have equipment that detects the wave motion of the mouse. Consistent with the contract by sending the computer. 4. the case for packing box is a device that uses the processor and the computer's memory in a device anchored to a stable, compact and organised labour migration. At the same time, such as fire protection safety suction. Protective devices to prevent loss and sent waves that interfere with the operation of other electronic device. 5. software (Software) about the job search is a program of the library information technology examination handbook/CDS database IS down to those okborikan publication information and facilities. To find a book to the user, which the user can order processing through various options for businesses under the eyes from the menu system. Text box: knowledge, software program or series (Sofrware) is a command and control commands to the computer hardware, we cannot work directly to the same software, hardware or software program, because this will be stored in the media used to record information such as the disc software.

Chapter 3 : Information Retrieval Unit essence, this is a lot of information published on the internet, with the number increasing all the time to get information into a daily lifestyle. Health professionals, the scientific knowledge is necessary to ensure that the work, so internet users have no knowledge of the techniques of finding information on the Internet. By using the services of a website that offers tools to Internet search resources on the Internet are rapidly expanding continuously throughout. The massive amounts of data The current generation of Internet users (user-generated con) is the user group community, social networking (social network) is a lot like Faceebook, MySpace HI5, Wikipedia, web blog, etc. I chose to study Ø.

Select the basic theory and evaluation system for storage and retrieval has eight. Analysis of technology and standards for the storage and retrieval of information on the performance of the unit, expressed no knowledge of the search information is searched information query information from all electronic systems today. Should have basic knowledge about the query and the database before. They're included in the process of searching the computer in other ways. Effectively query information refers to the process of finding information. Using various search engines. Retrieving information is divided into two ways: 1. Information searched by hand (Manual System) as Card sq Gibbons Journal of the two. Retrieving information by computer (Computer System) queries can be made ​​via devices including computers, electronic books database. Electronic journals And information retrieval on the Internet, etc. Information Query tool is used to find books available in the library. To be attributed to learning, including computer search is to find information about books in the race to maintain that the book is a book that people want to or not. If it is listed in the category of data is a sign of human perception and be recorded in the symbol. When data is managed, meaning or content. Thus changing the level of information technology is the fact the event is broadcast and recorded in various books, journals, newspapers, audiovisual materials and words, etc. to be used in deciding whether or edited many (books Wadi successor pine Barth, 2543) components. a tool for searching information Include : 1. The screen is a device output (Output devices), or display one type of computer with a display that information. Usually contains commercially text. And graphics 2 keyboard input devices (Input devices) are the main equipment used in information into the computer. There is usually a rectangle. Or closely with the keys on the keyboard do about a hundred keys. (Depending on the keyboard layout), which is adapted from the typewriter. To make data entry as easy and convenient alphanumeric keyboard is a separate panel keyboard with numeric keypad characters aside if exposed 3. mouse input devices (Input devices) in use to maintain control. in computers, designed to fit applications by arches and concave curves into the hands of those carried by the bottom of the mouse is a device which detects the motion of the mouse. The signals go to a computer 4. Oakes was the equipment used for packaging, processing and memory of computers inside them. In order to secure the device firmly compact K-slip move. Meanwhile, to prevent electric shock protection devices such as safety, loss prevention and sending waves interfere with other electronic devices 5. Software (Software) about the library's program guide information retrieval database preparation into CDS. / iS to print out those services. And facilities To find books to users. The user can process through the various options. Under the eye of the camera's menu system Box: Knowledge Software (Sofrware) is a program or set of instructions. To command and control the hardware, software, computer work, we can not be caught. Directly on the same hardware. Because the software or application is being stored on the media used to record information such as the disc software.
