ABSTRACT:
The process of searching starts with the user’s construction of his/her query statement based on his/her search topic and then narrow it down into concepts. But prior to the searching process, user should have at least idea on the measures to be taken during the search process. And then during the input of search query (keywords are determined, and Boolean operators are use on the search query), all symbols, images and other details are converted into binary digits (0s and 1s) in order for it to be understood and processed by the computer. Query statements that are gathered are converted and instructed in a computer through the input devices, and then the data are processed and manipulated in the CPU which controls the other parts of the computer systems while the microprocessor speeds up the process and retrieval of the information.
Once query statement is entered into the system, the computer is then instructed to find all the references in the database about the search concept. The Boolean operators play an important role during the search process.; it in the coordination of the search concepts----- with user’s familiarity of the keyword synonyms and use the Boolean operators the number of relevant document retrieved varies, it depends on how the search statement is being constructed. The results now can be too narrow or too broad, it could focus solely on one concept excluding the other concept (NOT logic), could retrieve all relevant concepts (AND logic), or relevant documents on either of the two concepts (OR logic). In an online based system, the search processing involves several communication devices that allow the transfer of information searched from one network to another; these communication devices are also the one responsible for connecting on databases that matches the concept being searched through host computers. The search results are then translated into language that human can understand, as output, and viewed through computer screens, printers, and other output devices.
3 THINGS I LEARNED:
First, unlike before that average person did not need to know how to use a computer, now, knowledge in computers is must to all professionals since we use it to get hold of information, evaluation of it, and to communicate it with other people.
Second, computers provided a great ease in the work processes involve in our daily life. It speeds – up most of the operations involve in our work. Hence, at present, you can already consider computer as part of commodity, especially for the academic and business community.
Lastly, since development in technology is very fast, we as information professionals should be kept informed with the use and technical aspects of these technologies, such as: knowing the different components of computers involve in information processing, because we are using it to provide and improve services for our clienteles.
IMPLICATIONS OF THE NEW THINGS I LEARNED:
Since the development and upgrades in computers is very fast, we should have familiarize ourselves with the components of computers so we could specifically identify which components need to be repaired or upgrade at times when we experienced technical problems with our computers. Although we can learn computers without knowing its technical aspects, still knowledge of its technical aspects is an advantage; knowing something about the computer can help us find and buy the right computer for our needs, and be able to maximize its use.
