The PS/2 connector

The PS/2 connector is used for connecting some keyboards and mice to a PC compatible computer system. Its comes from the IBM Personal System/2 series of personal computer, with which it was introduced in 1987. The PS/2 mouse connector generally replaced the older DE-9 RS-232 " serial mouse " connector, while the keyboard connector replaced the larger 5-pin DIN used in the IBM PC/AT design. The keyboard and mouse interfaces are eletrically similar with the main difference being that open collector outputs are required on both ends of the keyboard interface to allow bidirectional communication. If a PS/2 mouse is connected to a PS/2 keyboard port ( or if a PS/2 keyboard is connected to a PS/2 mouse port ),the mouse (or keyboard) may not be recognized by the computer depending on configuration, although most modern compuyers will recognize the hardware eigher way.

Digital Camera

A digital camera (or digicam for short) is a camera that takes video or still photographs,or both,digital by recording images via an eletronic image sensor.

Many compact digital stillcameras can record sound snd moving video as well as still photographs. Inthe Western market, digital cameras outsell their 35 mm film counterparts.

Digital camera can do things film camera cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device,recording video with sound,and deleting images to free storage.

Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical device are essentially specialised digital cameras.
