Briefly analyse research presentation methods before and after the advent of computer.

Before the advent of computers, research presentation methods relied heavily on traditional forms of communication and documentation. These methods were based on physical formats such as printed papers, books, posters, and oral presentations. The research process was manual, requiring researchers to compile their findings, organize their data, and present their conclusions in written reports or live discussions. The physical nature of research outputs, such as books and papers, made the distribution and accessibility of research findings more challenging. Researchers had to rely on typewriters or handwritten notes to prepare their reports, and the editing process was cumbersome, involving multiple revisions and physical corrections.

The most common method for presenting research during this period was through oral presentations at conferences or seminars, where researchers would speak directly to an audience, often using slides or handwritten diagrams to illustrate their points. Visual aids were limited by the available technology, such as chalkboards, posters, and printed handouts. In some cases, researchers used transparencies and projectors, but these methods were relatively slow and not as interactive or flexible as the computer-based tools we use today. Furthermore, the process of sharing research findings with others, especially across different geographical regions, required mailing physical copies of papers or relying on journals, which had a slower circulation time.

The presentation of research findings also depended on printed publications, including academic journals, books, and newsletters. The printing process itself was time-consuming and expensive, often limiting the number of people who could access the research. For a researcher to publish their findings in a journal, they had to submit physical copies of their manuscripts, which would be reviewed by peers and then printed, often leading to delays in disseminating new knowledge. This process was also more prone to human errors during manual transcription and editing. The advent of computers revolutionized research presentation ___ ____ _________ _____ ______ _______.
