Computer Pheriperal

Additional hardware peripherals are connected to the computer, usually with the help of cables.Peripheral is tasked with helping the computer to complete the task that can not be done by hardware that is mounted inside the casing. There are various types of peripherals with a variety of duties:

Keyboard.
Shaped like a typewriter that contain letters, numbers, special symbols and function keys. Point to give orders to the computer by writing or pressing a combination of a few buttons. Currently, a number of companies like Microsoft and Logitech already makes a keyboard without wires (wireless) that uses an infrared beam.

Mouse.
Tools like mice and consists of two or three buttons, functions to control the cursor / pointer on the screen monitor by way of moving forward, backward or laterally. It poses a rubber ball that will move the little wheels, which will regulate the movement cursor / pointer. Usually equipped with the latest generation of mouse scrolling button to make it easier to move down / up on the screen monitor. Mouse can also be used to play games.Now the wireless mouse has also been produced.



Trackball.
Its function is exactly the same as the mouse, just looks different. At the trackball, the ball that moves the cursor / pointer is outside and must be driven by our finger towards what we want. If we move the mouse body all over the table, the agency remained silent trackball in place. As with the keyboard and mouse, wireless trackball has also been on the market. Playing games with a trackball rather more difficult than the mouse.

Monitor
Looks like a television and function displays the process and results of computer work. Ancient computer monitor or a monochrome black and white only (sometimes with the word green or orange and black background). Now the monitor almost everything in color and high resolution, so that the resulting image quality is also much better.

Printer.
Used to print the paper or more computer processes that can be read. There are three types of printers that is widely known that dot-matrix printers, inkjet printers, and laser printers.

Scanner.
Used to retrieve the image prints (pictures, photos, writings) to be processed or displayed through a computer. There are two types of scanners, handy scanners (held and moved by hand), and flatbed scanner (similar to a photocopy machine.)

Microphone and speaker.
To enter and record their voices and listen to recordings that have been stored in the computer, or listen to music and sound from CD, MP3 or gaming.

Digital Camera.
It acts like a normal photo camera, it's just a direct result stored in computer data format. The result is much better than negative film prints.

External Modem.
External modem installed outside the casing and connected via cable, while the internal modem card that was plugged in the shape of the mainboard. Modem function convert digital signals to analog and vice versa, in order to send computer data over telephone lines. If you want to use the internet, the modem should be available.
