1.0 INTRODUCTION Science and technology constantly evolving and changing. The latest released product will surpassed the earliest. The earliest will only become a history. Therefore, computer scientist are striving to develop and finding the newest and ideal to fulfill the need of users. This assignment aimed to identify the computer components, its function, its importance as well as the latest and the future technologies of the pointing devices, central processing unit (CPU), memory, disk controller, disk, and monitor. 2.0 POINTING DEVICES Pointing device is an input devices that is used to allow user to input data to a computer. It is connected to the computers or laptops using a USB, PS/2, serial, or Bluetooth connection (Tyler, 2008). It functions to point somewhere on the monitor, click and drag item in the computer. It plays an importance role enables user interact with the computer for many purpose such as surfing the web, editing document, editing images, computer games (Kirschner, 2010) and many others. It is defined as a piece of equipment used for moving a cursor on a computer screen (Mac-Millan Dictionary). There are many types of pointing devices nowadays such as mouse, trackball, pointing stick, joystick, touch pad, touch screen, light pen and digitizer tablet. Pointing devices are used depend on the types of task to perform in the computer. For example, joystick is often used to control play games. Digitizer tablet and light pen is used for drawing new images or tracing old images. It is usually used for drawing maps and engineering design. However, the most commonly used pointing devices nowadays are the mouse and touch screen. Mouse has four types which are mechanical, optical, touch sensitive and wireless mou... ... middle of paper ... ...an the CRT monitors and the LCD monitors are significantly thinner having lower radiation emissions. Few years’ back, Plasma came in the scene and they are gradually making its space in the market. However, after that, LED displays came and won over Plasma and LCD technology which is has various advantages over LCD technology like better image quality, low power consumption. After that, the latest technology for monitor is the Organic Light Emitting Diode (OLED) which is has advantage over LED. It is directly produce the correct color, fast response time, wide viewing angles, outstanding contrast levels and perfect brightness, OLED displays are surely better than the existing other display technologies. OLED technology is used in commercial applications such as displays for mobile phones and portable digital media players, car radios and digital cameras among others.
