Keyboard (keyboard) The keyboard or the keyboard (keyboard) consists of the letter buttons. Numbers and symbols so that you can enter information into the computer. The keyboard is a device receiving the preliminary information. The keyboard is similar to the behavior of a typewriter, but has added computer-specific controls. The buttons are usually some 101 may be less or more than they are able to divide into groups as follows:101-key Enhanced keyboard104-key Windows keyboard82-key Apple standard keyboard108-key Apple Extended keyboardNotebook & Palm keyboardOperation of the keyboard.Operation of the keyboard are caused by changing the mechanism to hold electrical signals sent to the computer by a signal, it will tell the computer to know what key is pressed. All work will be controlled. Microprocessor (microprocessor), a miniature keyboard in the signal and passes the signal through a cable keyboard connector types are 4 split.5-pin DIN (Industrie Norm Deustche) connector is used with large connector first generation computers.6-pin IBM PS/2 mini-DIN connector is a small connector. Widely found today.4-pin USB (Universal Serial Bus) connector is a connector, a new version of the. Internal connector is an internal connector found in Notebook Computer.The buttons on the keyboard. To print the letters, we will use the same character arrangement in common typewriter, which we called the QWERTY, which is in the top row the 6 character renders. This kind of arrangement to make the print speed of typewriter company typewriter, the reason is reduced due to the creation of the working mechanism of the arms, fingers overlapping maphim check if someone typed too fast, and then it became a widely used long, until finally becoming the standard and user familiarity. Companies that manufacture the keyboard is a computer keyboard manufacturer for the same rai. Although there is no overlapping of the issues it printed sleeves. To describe the functionality of some buttons that are interesting.Alt keys will have two buttons next to the space bar is used as the auxiliary button Alt, similar to the shift button, that is, when we press A single screen, it appears the letter A, but if we press Alt with A at the same time, it will become a function of the Alt-A command, function, or operation of the command in each program are different.Crtl button will have two buttons, as well as an extra button Alt, as well as the Alt button works similar, for example, when you press Ctrl has been dyed with a character, a computer which may vary depending on the program used. Turn-key or button-window as a symbol of PUM is a window for the facility. In turn this button live programs on the left between Ctrl and Alt buttons this buttons are not working only with Windows operating systems only. In other operating systems, they can work as well. If there is a driver that monitors the press of a button-turn-key. Numeric buttons are part of the development of the keyboard for convenience in business. Button added to all 17 button which has a similar arrangement in the calculator, so ease of use 7. Most of the control buttons. Control button allows you to scroll pages or individual lines very much. The controls are as follows: Home End Insert Delete Page Up Page Down Control (Ctrl) Alternate (Alt) Escape (Esc)A button control. When working with other buttons to order something. Each District CommanderAlt + F4 to close the window that is open and start buttons, window or WK can work in conjunction with other buttons. As follows:WK + e-Windows Explorer launchWK + f – opens default for files or folders.WK + Ctrl + f – opens to find computers on the network.WK + M-Minimize command is run using the initial screen display or desktop.WK + Shift + M-minimize window is used to remove.WK + r Run dialog window, open a command-based.WK + F1 – opens the window for assistance.WK + Pause-opens The properties of the system (system properties)From your keyboard to your computerWhen you type on the keyboard. The control processor of the keyboard is referred to as a button button to analyze from where pushing down, keep them in a small memory size approximately 16 bytes, then it will be forwarded to the computer through the connection, there are several kinds of.A plug the keyboard in general are as follows: 5-pin DIN (Deustche Industrie Norm) connector 6-pin IBM PS/2 mini-DIN connector 4-pin USB (Universal Serial Bus) connector Internal connector is an internal connector found in Notebook Computer.The first 5-pin-DIN connector (Deustche Industrie Norm) is a large connector used on the first generation of computers. It is difficult to find, and in the present. Most computers used IBM 6-pin PS/2 mini-DIN connector is small, and they develop a 4-pin USB (Universal Serial Bus), but nevertheless, what type of keyboard connector. The principle of transit information to the computer. It must be reliable to the keys to work. In General, the keyboard will use approximately 5 volts and the ways to send information from the keyboard to the computer.At the end of the strap on the other side, there will be a section that examines the behavior of the keyboard. Called the control IC circuit, which is the keyboard. The keyboard controller to process any data that comes from your keyboard and sends it to the operating system. When an operating system is, it will check the following.Determine whether or not a system command. System commands such as Ctrl-Alt-Del, which is centered around a new computer commands.Programs that are currently running will get data from the keyboard in the program understand and determine whether or not a program's commands, such as file open command is Ctrl-O, etc.Programs that are currently running will be informed (if the information received did not take command) to continue.In addition, the program can also do not receive any information or commands from the keyboard or neglects the information submitted by.
