The relationship between human and computer has been long time ago and it just keeps growing up as the human’s world is developing. According to Vannevar Bush, technology is always new and very powerful (Vannevar 46); that’s why people have to rely on technology to the approach modern efficient world. With the current computer’s system, its functions are very complicated with significant noticeable features. However, the current computer system is not more than the information technology as the first product came into the world. In 1945, Vannevar Bush created the very first piece of technology; it’s called the Memex. “ A Memex is a device in which an individual stores all his books, records and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility” (Vannevar 53). There are four main components that operated the Memex system; they were microfilms with drawers, the screens, the keyboard and the stylus. Firstly, microfilms were used to record documents, communications and images; additionally, drawers were the storage for the microfilms as the library of microfilms were accessed through these drawers. Secondly, the screens displayed the projected items, the codes, the trails and allowed the direct entry of notes. Thirdly, the keyboard was used to enter codes, project the heads of trails and to duplicate established trails. Finally, the stylus was used for adding notes to project items (Vannevar 53). Nowadays, there are so many computers’ systems and devices are created base on the Memex’s system of Vannevar Bush; plus, it increased the technological human demands to higher levels.
