Mouse dan Keybord

At the meeting this time I will discuss about something unusual for you all, but you will not necessarily pahan Background information of this object is "MOUSE"
Mouse, or that the Indonesian language is called mouse, often we use everyday. Apparently, a lot of mouse development from the beginning until the mouse made a very popular art today. The first mouse invented by Douglas Engelbart of Stanford Research Institute in 1963. Mouse is one of several pointing device (pointing device) which was developed for the online system (NLS) Engelbard property. In addition to the mouse, which was originally called "bug", also developed a detector other body movements, such as equipment placed on the head to detect movement of the chin. Because of convenience and practicality, the mouse was selected.
The first mouse made Engelbard
The first large-sized mouse, and uses two wheels that are perpendicular to the axis motion detection axis X and Y. Engelbart later patent on November 17, 1970, with the name Pointer XY position for graphical display system (XY Position Indicator For A Display System). At the time, Engelbart actually intended users use the mouse with one hand constantly, while the other hand operates like a keyboard instrument with five buttons.
MOUSE BALL
Further development carried out by Bill Home at Xerox PARC in the early 1970s. He uses a ball that can spin kesegala direction, then spin the ball is detected by the sensor wheels inside the mouse. The development of this type gave birth Trackball mouse type, which is kind of inverted mouse where the user moves the ball with the fingers, a popular between 1980 to 1990. Xerox PARC is also popularized the use of a QWERTY keyboard with two hands and use the mouse when it needs it. Current mouse design follows the federales Ecole Polytechnique de Lausanne (EPFL) are inspired by Professor Jean-Daniel Nicoud.

Optical Mouse
In addition to the mouse ball, is widely used as an optical mouse. Superior optical mouse from the mouse ball for more accurate and easier to maintain than the mouse ball. Optical mouse does not need to be cleaned, unlike the ball mouse should be cleaned frequently because a lot of dust on the ball. The first optical mouse made by Steve Kirsch of Mouse Systems Corporation. This type of mouse uses LED (light emitting diode) and the photo diode to detect the mouse movement. The first optical mouse can only be used on pads (mousepad) a special metallic blue stripes - gray. Current optical mouse can be used almost any solid surface and flat, except for light-reflecting surface. Current optical mouse works by using optical sensors that use LED as a light source to take thousands of image frames for the mouse moves. Change of image frames are translated by a special chip to the position of X and Y are then sent to a computer.
LASER MOUSE
Laser Mouse was first introduced by Logitech, the mouse leading companies in collaboration with Agilent Technologies in 2004, with the name of the Logitech MX 1000. Logitech claims that the laser mouse has an accuracy rate 20 times greater than an optical mouse. Basis of the mouse and mouse optical laser is almost the same, the difference is only using a small laser instead of LED optical mouse use. We have a laser mouse has not been used, perhaps because the price is still expensive.
Of all the developments mouse, which has not changed much is the number of buttons. All the mouse has buttons between one to three fruits. The first mouse has one button. Most mice today, which is designed for Microsoft Windows, has two buttons. Some modern mouse has a wheel for easy scrolling. Meanwhile, Apple introduced a single button mouse, which was not changed until now.

Modern mouse also has many without cable, that is using wireless technologies such as Infra Red, Bluetooth or radio waves. Popular wireless mouse is currently using radio waves or Bluetooth. While the mouse that uses Infra Red less popular because of the limited distance range, while also not practical because of the mouse and the receiver must not be obstructed.

MONITOR
In using this application must be connected to computer network from one computer to another computer in order to function properly, because this is the main requirement. If the computer is stand alone so that the application is not useful. In this program work at least use the network group. In the picture below Monitormagic application model.
MonitorMagic an application that can deliver or post an enterprise solution on the network using windows 2000 operating system and Windows NT servers, workstationnya and SNMP devices.
Saving MonitorMagic a network administrator valuable time by monitoring the network and provide important management information. to use MonitorMagic It simplifies network management implementation with the use of a customizable and familiar monitoring and alerting unit measures, the policy called / summoned. MonitorMagic is a complete network monitoring and solutions
In addition to monitoring and alerting can be considered as MonitorMagic reported. This valuable addition of a unique MonitorMagic selling network management. With the same simplicity as the monitoring and alerting. Some main features are MonitorMagics windows NT/2000/XP/2003 Supports, Supports SNMP devices, Supports monitoring with and without agents, provide a web-interface without the need to install IIS.
Monitor History

Computer monitor is a type of output device that seeks persisian expose askara and / or images, either still or moving, which dijanakan by computer and by determined progress graph.
Monitor Tedapat four types, namely monochrome monitor, color monitor, Monitor segerak berbilang, and Monitor Eld (Electro luminescent display). Each monitor has the characteristics and history.
Monitor the quality depends on several factors. Which mainly is the number of pixels is presented by skrinnya; pikselnya more, more sharp text and graphics are presented.
At first all the monitors are of katod ray tiub (CRT) is the same as that used in tiub Televisyen, but now LCD monitors increasingly popular type of LCD monitor kerana use a small space, light and electrical energy is more proportionate menjimatkan CRT monitors

Monitor History



The term "mod exposure" refers to the characteristics of exposure to computers, especially the maximum number of colors and the maximum image separation (in pixels and pixel row latitude). There is a lot of exposure that can mod in the computer system found in a personal way today.
Exposure for cloning the earliest computer is monochrome monitor is used for word processing and computer systems based on the text dekad of 1970. In 1981, IBM introduced a system of tuning exposure Graphic Color (CGA). Exposure system is working to provide four-color, and has a maximum of 320 separation piksels flat and 200 pixels tall. Although CGA sufficient to use simple computer games like solitaire games and drafts, he was not sufficient for word processing, publishing on the table or use sophisticated graphics.
In 1984, IBM introduced a system of tuning graphic presentation Tertingkat (EGA) which can provide so that 16 different colors and the denouement, so 640 x 350. This fix seems proportional earlier exposure, and allow easy reading of the text. However, EGA did not provide sufficient separation for image purposes such as their high point of the graph and the publication of the table. This mod is now obsolete, although he still kekadang be found in the old and the computer processing at the residence of cloning.
In 1987, IBM introduced the system of exposure Tatasusunan Graphic Video (VGA). Now, it has an excellent minimum acceptable for the computer for cloning. The maximum separation depends on the number of colors presented. Users can choose between sixteen colors at 640 x 480, or 256 colors at 320 x 200.
In 1990, IBM introduced a system of graph Tatasusunan widest exposure (XGA) as heir to exposure to 8514 / A. The following versions, namely XGS-2, providing separation 800 x 600 pixels in true color (16 million colors) and the denouement in 1024 x 768 in 65,536 colors. Second-stage separation of two images is perhaps the most popular types among individuals and small trade today.
Expert-expert unity Electronics Video (VESA) has mengasaskan between pengaturcaraan skilled to face exposure Tatasusunan Super Video Graphics (SVGA), which dubbed connection VESA BIOS ( "VESA BIOS Extension"). Typically, exposure SVGA palettes that can support 16 million colors, depending on the amount of available video memory in a computer something that will menghadkan color numbers can be presented. Specifications denouement cadar cadas-Beza image. In general, larger skrin SVGA monitor, more pixels can be described as flat and upright
