Experiment 2: Identify Common ports, associated cables and their connectors. Aim To identify Identify Common Peripheral ports, associated cables and their connectors. Objectives After performing this experiment students will be able to:  Identify various ports.  Identify different types of cables used in computer.  Identify various connectors. Assumptions  Students have basic knowledge of English language and A Computre System Requirement Screw Driver Software Nil Requirement Learning Major Learning outcome of this experiment are: Outcome  Identifying Ports, Cables and Connectors

THEORY Port  The Point at which peripheral attaches to.  Communicates with a system unit so that peripheral can send data to or receive information from the computer. Following are the different Types of Ports of Computer System. 1) PS/2 Ports The PS/2 Ports are simple, 6-pin, low-speed serial connections commonly dedicated to a keyboard and mouse. Although these ports may look identical at first glance, they are not interchangeable, so you'll need to be extremely careful to attach the keyboard and mouse to their respective PS/2 port. 2) VGA Mointer Port Video Graphics Array: used to connect the monitor to the computer 3)

The parallel port originally started out as a unidirectional (output only) Printers and other devices are said to be either parallel or serial. Parallel means the device is capable of receiving more than one at a time (that is, it receives several in parallel). Most modern printers are parallel. 4) Port A local-area network (LAN) architecture developed by Xerox Corporation in cooperation with DEC and Intel in 1976. It is one of the most widely implemented LAN standards. 5) Video Port Short for Super-Video, a technology for transmitting video signals over a cable by dividing the video information into two separate signals: one for color (chrominance), and the other for brightness (luminance). 6) Monitor Port Short for Digital Visual , a digital interface standard created by the Digital Display Working Group (DDWG) to convert analog signals into digital signals to accommodate both analog and digital monitors. 7) USB Port Universal Serial Bus: a protocol for transferring data to and from digital devices. Many digital cameras and readers connect to the USB port on a computer. USB card readers are typically faster than cameras or readers that connect to the serial port, but slower than those that connect via FireWire.

Cable are complex machines consisting of many interconnected parts. While certain computer components plug directly into the , many computer devices such as hard drives, mice, and digital cameras must be connected to a system using cables or cords. There are many types of cables that can allow devices to connect to a computer.

Connector Joins cable and a port. A connector at one end of the cable attaches to a port on a peripheral. Most have the following connectors:  Serial port, which uses a DB9 connector, for connecting older devices;

 Parallel port, which uses a DB25 connector, mainly for connecting old printers;

 USB ports (1.1, low-speed, or 2.0, high-speed), for connecting more recent peripherals;

 RJ45 connector (called the LAN port or Ethernet port), for connecting the computer to a network. It interfaces with a network card built into the motherboard;

 VGA connector (called SUB-D15), used for hooking up a monitor. This connector interfaces with the built-in graphics card;

 Jacks (Line-In, Line-Out and ), for connecting speakers or a hi-fi sound system, as well as a microphone. This connector interfaces with the built- in
